as well as video interviews with thought leaders on clean energy policy topics.
Today’s webinar agenda is centered around the presentations from our guest panelists
Elena Berger, Meredydd Evans and Sha Yu, Jyotirmay Mathur and Bhaskar Deol. These panelists have
been kind enough to join us to review the progress with ECBC implementation in India
and analyze the economic impacts of ECBC-compliant buildings.
Before our speakers begin their presentations I will provide a short informative overview
of the Clean Energy Solutions Center Initiative. Then, following the presentations, we will
have a Question and Answer session where the panelists will address questions submitted
by the audience, then closing remarks and a brief evaluation.
This slide provides us with a bit of background in terms of how the Solutions Center came
to be. The Solutions Center is one of 13 initiatives of the Clean Energy Ministerial that was launched
in April of 2011 and is primarily led by Australia, the United States, and other CEM partners.
Outcomes of this unique initiative include support of developing countries and emerging
economies through enhancement of resources on policies relating to energy access, no-cost
expert policy assistance, peer to peer learning and training tools, such as the webinar you
are attending today.
The Solutions Center has four primary goals: It serves as a clearinghouse of clean energy
policy resources. It also serves to share policy best practices, data, and analysis
tools specific to clean energy policies and programs. The Solutions Center delivers dynamic
services that enable expert assistance, learning, and peer to peer sharing of experiences. And
lastly, the Center fosters dialogue on emerging policy issues and innovation around the globe.
Our primary audience is energy policy makers and analysts from governments and technical
organizations in all countries, but we also strive to engage with the private sector,
NGOs, and civil society.
A marquee feature that the Solutions Center provides is the no-cost expert policy assistance
known as "Ask-an-Expert." The Ask an Expert program has established a broad team of over
30 experts from around the globe who are available to provide remote policy advice and analysis
to all countries at no cost. For example, in the area of Buildings we are very pleased
to have Cesar Treviño, Leader Mexico Green Building Council serving as one of our experts.
If you have a need for policy assistance in Buildings or any other clean energy sector,
we encourage you to use this valuable service. Again, this assistance is provided free of
charge. To find out if the Ask-an-Expert service can benefit your work please contact Sean
Esterly directly at sean.esterly@nrel.gov or at 303.384.7436. We also invite you to
spread the word about this service to those in your networks and organizations.
In summary, we encourage you to explore and take advantage of the Solutions Center resources
and services including the expert policy assistance, the database of clean energy policy resources,
subscribe to our newsletter, and participate in webinars like this one.
Now, I’d like to provide brief introductions for today’s panelists.
First up today is Dr. Elena Berger. Dr. Elena Berger is a Science and Technology Fellow
at the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, International
Program, currently managing the portfolio of projects in renewable and energy efficiency
in collaboration with India. Following Dr. Berger we will hear from Meredydd
Evans. Meredydd is an energy policy and finance expert with over 20 years of international
experience and has worked on energy efficiency and clean energy policies and projects in
numerous countries.
Presenting with Meredydd will be Sha Yu. Sha is a scientist at the Pacific Northwest National
Laboratory.
After Meredydd and Sha we will hear from Jyotirmay Mathur. Jyotirmay is a mechanical engineer,
with postgraduate degrees in energy from the Indian Institute of Technology, in New Delhi
(India) and the University of Essen (Germany)
Our final presenter today will be Bhaskar Deol. Bhaskar is an India representative with
NRDC’s India Team and is based in New Delhi.
And with those introductions I’d like to welcome Dr. Berger to the webinar. Dr. Berger?
>> ELENA BERGER: Thank you Emily for that introduction. So I'm waiting to see the presentation.
>> EMILY EVANS: And we're getting the slide up. Just give us one moment.
>> ELENA BERGER: Thank you very much and thank you for joining this webinar given by the
US Department of Energy and organized by the Pacific Northwest National Laboratory (PNNL)
with the participation of the Malaviya Institute of Technology (MNIT) and the Natural Resources
Defense Council (NRDC). I thank you, our partners, at MNIT and NRDC for cooperating with us in
organizing this webinar. Next slide please.
I would also like to acknowledge our great partners who helped us disseminate information
about this webinar. Next slide please.
This webinar in our continuing work to support the adoption of building codes in India takes
place within the framework of our bilateral partnership between India and the United States
and in the recent meeting between Prime Minister Modi and President Obama the two leaders emphasized
the commitment of the two countries in advancing the partnership in energy and climate change.
Next slide please
The Partnership to Advance Clean Energy or PACE has three main components: PACE-D for
deployment, PACE-R for research and development, and PEACE for energy access. Building codes
belong to the deployment arm of PACE along with other energy efficiency activities, renewable
energy, clean fossil, and clean energy finance efforts. Next slide please
The Partnership to Advance Clean Energy or PACE takes place under the umbrella of the
Indo-US Energy Dialogue and its six working groups. The cooperation on renewable energy
and energy efficiency technology are managed under two working groups - Power & Energy
Efficiency and New Technology & Renewable Energy working groups. Next slide please
The Indo-US Collaboration for the adoption of ECBC is managed under the Power and Energy
Efficiency working group. Under this collaboration DOE and PNNL have been engaged with the government
of Rajasthan and MNIT since 2011 in two main efforts - Training and Institutional Support
and Incentives. We believe that these efforts are very important to advance the main barriers
that have presented the adoption of building codes in India.
On training, PNNL and MNIT have developed and delivered training workshops and stakeholder
meetings in Rajasthan and have developed set of training materials on ECBC 101. On institutional
support, PNNL and MNIT have developed an ECBC roadmap in collaboration with the government
of Rajasthan, and we have created an award to accelerate the adoption of the code by
stakeholders in the state. You will learn more from my colleagues from PNNL that do
provide in great detail and talk about these activities in Rajasthan.
More recently PNNL has collaborated with MNIT on two ECBC compliant pilot buildings at the
MNIT campus and details about this pilot will be presented by Dr. Jyotirmay Mathur from
MNIT during this webinar. Mr. Deol Bhaskar from NRDC will also provide case studies from
successes in the state of Andhra Pradesh and I thank you NRDC for being a great partner
all along in collaborating with us to disseminate the benefits of ECBC doing this webinar. I
hope you really enjoy the information that we are trying to convey during this session
and will be happy to answer questions at the end of this webinar. Thank you for your attention.
>> EMILY EVANS: Thank you Elena. I will now hand it off to Meredydd Evans and Sha Yu who
will talk to us about the ECBC implementation, progress, lessons learned and options. Meredydd
and Sha?
>> MEREDYDD EVANS: Hi, thank you. While the slides are loading...great, I see them right
there. I'd like to first say thank you for joining us and I'm looking forward to sharing
a few thoughts with you. Next slide please
So, on ECBC implementation today I'll describe a couple of themes. First off is an introduction
- why ECBC is important and what it is. I'll also talk about progress with implementation
and some lessons learned in Rajasthan. Sha Yu will then describe tools for implementation
and some takeaway points. Next slide
This slide you can see two figures that highlight the core reason for focusing on new buildings
in India. They show projections that our institute has done using integrative assessment modeling.
They present data on the likely growth in floor space in billion square meters, both
in commercial and residential space, from now through 2095 as well as the linked increase
in energy demand those buildings in a scenario where there are no specific building policies,
like building energy codes. You can see there is a likely tremendous growth in the amount
of floor space so by 2050 we are talking something like 35 billion square meters of new buildings.
Energy use in those buildings would increase substantially as well. That could put tremendous
pressure on India's power system as well as its overall energy systems and instead there
is an alternative to save energy and to reduce the energy impact of those buildings while
still maintaining comfort. Next slide please
So here you can see some analysis the business case for the ECBC. We show calculated savings
for ECBC compliant buildings versus typical buildings in different cities in India. The
savings are really impressive - 25-40% of the energy can be saved, depending on exactly
where the building is and whether it is a building that is used 24 hours a day or is
used during day time. Regardless, very impressive figures and what's more those savings are
cost effective. Next slide Which means that the savings themselves, the
reduction in energy consumption, can pay for itself, can pay for the investments themselves.
In addition, ECBC implementation can reduce CO2 emissions and it can accelerate deployment
of energy-efficient technologies. Next slide
So, what is ECBC? Just a quick overview. It was issued in 2007 by the Ministry of Power
and the Bureau of Energy Efficiency. It's mandatory in the states that have adopted
it for all new commercial buildings with connected load over 100kW, basically for all large new
commercial buildings. It's different from voluntary labels like LEED because it is mandatory
and it applies to all buildings in those jurisdictions. ECBC addresses building envelope - so the
walls, windows, etc., HVAC, lighting, electrical systems, hot water, and pumping. And it allows
for three different compliance approaches: A prescriptive approach with specific levels
of say insulation or specific types of windows allowed, a trade-off option with slightly
more flexibility, and a whole building performance approach that requires the use of sophisticated
building simulation software. So just to recap a couple of the differences between ECBC and
green building labels such as LEED or GRIHA, ECBC is mandatory and it covers presumably
all buildings in the jurisdictions that adopt it. ECBC covers only the energy provisions,
so not other energy issues, other non-energy issues like water. ECBC is not score based
but rather it's based on engineering principles. Next slide
Here is a little bit of information on the implications of ECBC for different stakeholder
groups. I know that the next speakers will talk a little bit more about this so I will
go over it quickly. For example, local governments or ULBs will need to add code requirements
if they have not already done so in order to make ECBC effective. They also need to
be involved in ECBC enforcement, for example, involving their party inspectors as one option.
Manufacturers will likely see an extended market for energy efficiency products and
materials. Real estate and construction companies will need to ensure code compliance during
building construction for new buildings. Developers, like architects or engineers, need to make
sure they integrate the code into their building design and that they document compliance for
code authorities. Next slide
So, today ECBC has been adopted by a range of states in India. You can see the Bureau
of Energy Efficiency lists the states and their status in terms of whether they have
issued formal notification to make it mandatory or they're in some other stage of the process.
The number of states is growing all the time and it is at that level that ECBC then becomes
mandatory. Next slide
Focusing on Rajasthan, a few of the milestones there with the ECBC implementation: In March
2011, the Rajasthan government adopted ECBC with minor additions. In September 2011, then
ECBC entered into force. Compliance became mandatory. Then in June 2012 another important
step was that ECBC incorporated into the local bylaws, which made it formally a part of the
process for approving buildings. Since 2011, DOE and PNNL have worked with the government
of Rajasthan and MNIT to support roll out of ECBC and build capacity among stakeholders.
Next slide
Finally, on my side, a couple of lessons in terms of the barriers of implementation. In
a nutshell, it's capacity. In particular, state and local governments lack, in many
cases, the capacity and resources to implement and enforce the code. ULBs, would typically
be the primary enforcement entities, lack technical expertise and staff to implement
ECBC effectively in many jurisdictions. So that is an important barrier. Sha will talk
about some alternatives that can help boost this capacity. In addition, building professionals,
while their experience with ECBC is growing rapidly, many still lack capacity and/or access
to energy simulation programs that are required for the whole building compliance test. So
that is one reason we are really excited to hold this webinar and share a little bit of
information, raise interest in ECBC. On a slightly different topic there is somewhat
limited capacity for testing building materials and equipment, which is essential to make
sure that those materials actually match what is required under the code. Overall, stakeholders
cited the lack of code training as the most important barrier for ECBC implementation.
Fortunately that is something that we can actually address together. With that I'd like
to turn it over to Sha.
>> SHA YU: Thank you Meredydd. Next slide please.
As Meredydd mentioned earlier, there are several barriers for ECBC implementation and fortunately
there are approaches and tools that can help tackle these barriers and [inaudible 22:57]
the ECBC implementation. One important aspect is to raise capacity of relevant stakeholders
through training, trainer-to-trainer programs, and potential use of certified third parties
in the states. ULBs, in particular, is critical for adopting and enforcing ECBC and monitoring
the progress. So, raising awareness of ULBs and building their capacity will help roll
out implementation and increase compliance. At the same time, testing and rating of energy
efficient materials is important and is actually an important building block for all building
energy policies, including ECBC. So, the best testing and rating system will help and guarantee
that building contractors meet all of the design specifications. Finally, there are
several software tools that could make compliance easier for designers, for ULBs, for consultants
and I will further discuss the software in the later slides. Next one please
There are three major tools or approaches that I'm going to discuss today and that would
be the potential use of third-party assessors in ECBC implementation and some training and
capacity activities that have been done and in the end the compliance software in India
or other countries. Next one please
As discussed earlier, limited capacity and human resources of ULBs is one of the major
barriers for ECBC implementation. The potential use of third-party assessors could help alleviate
burdens on local and state governments and help improve capacity irrevocably. For developers,
this approach could potentially reduce permitting application times and make it faster. It also
provides a signal to view the market in earnest in general. These third-parties have been
done in several other countries, including US, China, and some European countries, in
code implementation and it's proven effective in building capacity and maintaining code
implementation. For example in China by using third parties they have been successfully
increased compliance rates from around 50% in 2005 to close to 100% today in major cities.
So it is a huge improvement in the past 8 years, and the use of third-parties, largely
contribute to this progress. Third-party factors could be architects, engineers, and other
consultants that have past experience in building energy efficiency and certified. Currently
the Bureau of Energy Efficiency is developing a national certification system for third-parties
through a National Productivity Council. So people that have experience in building energy
efficiency might be qualified as third-party assessors after taking exams and certified
by the Bureau of Energy Efficiency and National Productivity Council. I think in Rajasthan
we are discussing the potential of using third-parties and in Andhra Pradesh, as I will discuss later,
they are also looking at the third-party approaches. Designers, developers and ULBs potentially
could work with third-party inspectors during the design and construction stages and this
might have some potential growth of third-parties during both plan review and construction and
inspection stages including, for example, in plan review you need to check building
plans, review materials, and specification, as well as calculations. Next one please
As discussed earlier, there are several benefits of using third-parties such as building capacity,
increasing market opportunities, and foster permitting process. However, it may also slightly
increase the cost of developers by paying third-parties. The third-party system also
requires multiple checks and balances to guarantee a fair process. Several factors that need
to be considered when designing a third-party system this would include: a robust third-party
training and certification program, which the Bureau of Energy Efficiency is doing right
now; and random checks of approved projects; and also there might be penalties involved
if there is a violation. Next one please
So, while ECBC has mandatory energy requirements for all building components and it affects
plan review, design, construction, as well as equipment installation. So to raise awareness
of stakeholders, PNNL has been collaborating with MNIT to develop training materials and
conduct ECBC training for different stakeholder groups in Rajasthan. The training materials
we developed complement the existing training materials developed by US AID and BEE group
and covers both general introduction information about ECBC and specifications for different
building components. It has been found in the US and elsewhere that training is multifactive
when targeting specific stakeholder groups. So in light we have conducted separate training
for architects, for ULBs, and for engineers in Rajasthan. We will share a link of all
the training materials we have developed with this presentation later. Next one please
Here is an example slide we took from the Code 101 training that MNIT and PNNL developed.
Code 101 training in general includes the general knowledge of building energy efficiency,
specific information about ECBC, and relevant compliance rate with a comprehensive approach,
like prescriptive, trade off, and whole building performance. In particular, Code 101 talks
about how ECBC is relevant to you as an architect, engineer, government official, or developer.
We also include a few case studies showing energy things and economic benefits of ECBC
compliant buildings. Later we'll show a concrete example of how the building will perform if
it's an ECBC compliant building based on our pilot on the Pacific Northwest campus.
In general as Meredydd talked earlier, ECBC sets minimum requirements for building systems.
For example, much of building energy use comes in the form of cooling and ventilation in
India so ECBC set minimum criteria for the HVAC system and equipment taking into consideration
the energy amounts of the building space. Architects, builders, and developers together
all need to collaboratively implement ECBC during the building design and construction
process. That will be including meeting all the code requirements including ECBC requirements
within the budget constraints. Also, that would affect the material selection and installation.
For example, by doing or installing proper insulation of materials and correct efficiency
replacings. The next one please.
There are several useful tools that could facilitate the compliance checks and code
implementation. Here in this slide we give some examples of compliance software. For
example, ECOnirman Prescriptive, developed by USAID and BEE, based on a contract to use
in the US. It is a web-based to provide compliance check software for both prescriptive and trade
off approaches. The software could help compute compliance results for building components
and will help generate reports that could be reviewed by ULBs and code officials later.
Next one please
So as a conclusion slide, we learn from the experience in Rajasthan that there are benefits of implementing
ECBC. As Meredydd talked earlier, in general it can save you 25-40% off energy and it is
cost effective. Building code is mandatory once it is adopted. It is definitely requirement
energy for building systems. Learning from Rajasthan, there are some common problems
in code implementation such as lack of capacity and lack of building materials [inaudible
32:14] systems but there are potential tools that could help address this problem, including
the use of third-parties. Some useful tools are software and the continuing of training
programs in multiple places for different stakeholder groups.
Going forward there are priorities we feel important in administering ECBC implementation.
Important stakeholders like ULBs are critical to building capacity and through training
and awareness raising programs and because they are critical in terms of adopting ECBC
and checking the progress and also for the design professionals it is also important
to increase their capacity through training and other activities. They are part of the
design process but they could also serve potentially as third-parties. The last one. Next one please.
In the end of the presentation we actually pulled together a few of the resources you
can further refer to after the presentation and thank you for listening today and now
I will turn over to Emily.
>> EMILY EVANS: Thank you Sha and Meredydd for that excellent presentation. Now I'd like
to hand it over to Jyotirmay who will talk about the ECBC impacts and the experiences
from the ECBC pilot building in India. Jyotirmay?
>> JYOTIRMAY MATHUR: Thank you very much and thank you all the participants who are there
online with us for joining and seeing how we try to implement ECBC and the pilot building
at MNIT. I'm also thankful to my co-presenter, Tarush Chandra, who is a colleague of mine
and he was also the architect of this building. He will also be available to answer any questions
related to the architecture of this building.
So the overview of my presentation is first of all I would like to describe the project,
then a little bit about the climatic conditions on the site for those that are not in Jaipur
or around, the benefits of code compliance buildings, how we proceed and how we convinced
our administrators and finance persons to take decisions, specifications of components
and systems, simulation results, and summary of our experiences. Next slide
So this building was already existing as a single floor, partially air conditioned building
of about 4,000 square meters. Then we decided to have one floor on the top of it. Once the
work started another receipt was taken, which was quite important. One more floor was to
be added and then third addition was to make a major retrofitting on the ground floor itself,
which was partially conditioned initially.
So the present status is that currently the first floor and the second floor, they are
ready. The first floor is already operational in one half of it. The second floor is undergoing
some furniture fitting. It will also be functional very soon. Ground floor is at the finishing
stage so we very soon will have this building functional. A simulation of this building
is performed on the basis of design and specifications of the installed systems. The simulation will
be revised after the ground floor is also finished because of some decision, if it is
taken, till the time of completion of the ground floor that would require us to move
[inaudible 36:06]. So the results, which I present today, might be slightly different
than finally after results will be after final completion of the total building.
So the building is basically used, or going to be used, for an office purpose and a computer
center. So the building operates 8 AM to 8 PM as an office but the computer laboratories
they work around the clock and also on the weekends partially. All the number of floors
is G+2. The total carpeted area now on the three floors is 11,306 square meters and most
of it is conditioned now. The window to wall ratio of this building is about 27%.
If you Google Design Center MNIT you will find an image, which is there on the left
hand side and on the right hand side I have a circle, which is showing the design center
building. On the further right of this building is the next project, which we are working
on, and this is the lecture theater complex. We call it Vivekanand Lecture Theater Complex.
We can review the results of this theater later.
The climate conditions of Jaipur, which falls in composite climatic zone. As for the climatic
classification of India, it has a latitude of 26.5, longitude 75.5, we have elevation
390 meters, cooling degree days are relatively high - 5,732, and heating degree days at 141.
So as on the right hand side we have shown that the monthly mean temperature is reading
from maximum of 35 to minimum of about 15. The humidity is also reading quite a lot.
The minimum is about 18%, which is very dry in April to a maximum of a quite high value.
This is the rainy season.
On this graph I tried to show the relative humidity in a pictorial way and, in a sense,
this humidity and dry bulb temperature as well. The dry bulb temperature, these dark
red points, represent very hot time in a year. That is from April to the mid of July. We
have very cold, as per Indian definition; we call about 2 degrees, 3 degrees, 4, degrees
as very cold temperature. They are in the month of December as on the chart. Dry weather
is in the month of April and humid weather is in the month of July.
For the features of Design Center Building, we have going to the east side of the building,
which is the main entrance, we have an entrance, which is projected and self-shading, and I
will show a picture of how the building is of self-shading time. We have on the south
side of staircase and a corridor and a facility area, which is the toilet block. The reason
for doing this was to reduce the heat from the south side. On the west side we have this
projected area as a ramp and this ramp is designed with a feature that when we have
evening low altitude sun this ramp actually shades the left side of my west facade. Similarly
if it is on the left hand side that is toward the south it shades the right hand side of
the facade. This ramp is actually helping us in shading the facade. There are fence,
and we are also using fence on the sides, including north side, because again for the
low altitude sun these fence are useful for the solar ingress to the windows.
We have a courtyard that was already existing in this building. We have retained this courtyard
as its feature. These are the four photographs. On the east side, as you are seeing, this
is the front elevation of the building. This is going to the main entrance of this building.
We have the north side and the fence. You can see the fence on this photograph. We have
the south side. We have the pilot block. We have the corridors. We have the staircase.
This is the ramp area, which is shaded, so you can see that this part of the building,
the left part of the building, is shaded by this ramp.
Some more pictures - this is the finished part of the front entrance and the glass is
completely shaded as you can see. Even the shading is coming to the lower part of the
down floor. On the right inside picture you can also see that shading - the facade is
shaded and some of the windows are completely shaded because of the self-shading nature
of the building.
Motivation for us to go for code compliance was first of all the notification issued to
us by the government of Rajasthan, which mandated implementation of ECBC. Then, major motivation
was not the code actually. It was less operating cost of the building and less connected load,
which also reduces our demand charges. We have reduced capacity of transformer now in
this building as compared to a conventional way. We have reduced our capacity of electrical
panel and circuit breakers in this building and acceptable payback and internal rate of
return of energy conservation measures were also motivation to go beyond ECBC. So in this
building we have not stopped. We started to look at ECBC level but then we thought that
the paybacks were quite attractive and there is a margin we could go beyond ECBC and that
is what we have done. Additional purpose for going for this building was also to learn
by doing it, to build capacity, and showcase energy conservation measures.
The first thing we did was to be supplied the applicability check through various definitions
under the scope of ECBC. So if it is a non-residential building of more than 100 kW and there is
an addition of two floors in this building, the ground floor is also undergoing major
retrofitting, and therefore it is coming under the coverage.
After we were done with the compliance check, we decided to go for whole building simulation
and not prescriptive route. There were three reasons finally - flexibility in selection
of elements and systems. We had a non-standard design of shading fin. We had to curve the
design of fin for integrating the ground floor with the extended second floor. So the first
floor was integrating the ground floor with the second floor through a curved fin. There
was no way in a prescriptive approach we could have the compliance with this fin. Ground
floor wall insulation, because it was already existing, was difficult to implement the insulation
on the ground floor. That is also another reason we did not go for the prescriptive
route.
The features of envelope are we have used XPS insulation on the roof and tiles on the
terrace. We have 1.5" sandwiched insulation in the wall. We have double glazed unit with
low E-coating on surface number 2 with UPVC frame. We have vertical fins and also overhangs.
The HVAC system is VRF type. We have used heat pumps also in areas with high occupancy.
Duct insulation is with PU foam. We have dimmable LED lights with daylight integration and in
addition we have 150 kW peak of solar implants. This is not a requirement of ECBC but still
we have done it. I will cover it slightly later.
If you compare with the prescriptive requirements of ECBC, which are also - to be fair - in
the standards rates of modeling, the wall insulation requirement was wall U-value of
.440. Whereas, we have stopped at .72 because we have other payback limitations. Going for
a higher insulation was requiring an unacceptable payback period and there we opted out. On
the roof, on the other hand, what we have done was the code was .409 but we have gone
for .35. The reasons are as listed below. We have under deck insulation on this roof
because our construction people and construction agency was not very confident about providing
us waterproofing guarantee. We agreed .409 insulation and therefore to compensate for
the lesser effectiveness of under deck insulation we have provided excess insulation through
inverted earth pots on the top side. We have also taken the decision about insulation on
wall and roof not only based upon the payback but also we have included the cost of avoided
tonnage. A lot of rounds of simulation were done and the U-value of roof, as I said, is
finally lower than the U-value of the code. Glazing selection was also done through the
help of simulation. So the U-value of 3.3 at required by the code, we have 2.2 as U-value.
SHGC is a little higher and there was a very specific reason of doing this. As I've listed
in the slide again, what happens is SHGC and VLT, they are linked with each other. If we
use the SHGC below a certain level the daylight ingress to the building also reduces. What
we have done is try to see effectiveness of different glazings and we stopped at .28 level
because this was offering us a glazing of .39 visible light transference and we were
getting an optimal combination of the daylight usage and keeping the building cool through
this combination. Also, there was another reason that we added shading to fins and overhangs.
If we apply shading adjustment factor to the U-value of .28 I would anyways be having a
value of less than .25. We did a total calculation because we did not have a conversion factor
for the curved fin. So we took the average length of fin and then we did the rough calculations
and we were convinced that this building was going to be code compliant. It may be lower
than the prescriptive value but the sim was based upon simulations.
A special care, which I will finally recommended through this webinar is that when you decide
about window glass, that time only we should go for the decision about lighting type. That
is what we did about this building because we were investing a lot of with glazing. If
we do not use available light in our interiors, the investment in glazing would go waste.
That is what we took care of in this building, that we took both the decisions together.
We also took another decision that 30% of the window area was kept openable so that
the building can also operate in mixed mode, although we have not modeled this in mixed
mode because presently we are operating it as fully conditioned and non-open window conditioning.
The light condition the ECBC requires is 10.8 watt per square meter LPD, whereas we have
gone with efficient LEDs - an LPD of 5.38 dimmable with daylight integration. We have
a combination of square 2x2 lights with 6" round down-lighters in the building. As you
can see on the right on slide there, there are two pictures. These are the square lights
and these other down-lighters, which are in the corridor. With the help of simulation
we have decided on these low LED. We measured the levels and they are sufficient and acceptable
as per ECBC requirements.
We have VRF systems and they are multiple units. There are 54 numbers of units installed
variable refrigerant machines where the standard says that the chiller would be a screw type,
with a COP of 3.05. This table has been given because we have modeled the standard HVAC
system according to this table, whereas the design case has been modeled after VRF.
There were certain reasons for going for VRF. Limited availability of water was forcing
us to use air cooled systems. The building is likely to have a large diversity due to
vacation of students, exam periods, seminars and training programs. Some of the sections
would be totally closed. The third reason was that discernable, exact uses of the building,
as I explained in the beginning of this presentation, that it was taken in steps. This was forcing
us, all of these three reasons together. It was forcing us to use VRF systems.
An additional feature that is not ECBC but we've gone for it is 150 watt kW peak of solar
plant on this. So there are three units of 50 kW each crystalline units. We have 6 of
the number of models, 50kVA*3/inverter, and in a string there are 15 modules and there
are 14 strings. What we have also taken care of is that, because on Saturdays and Sundays
most of the offices in this building would be closed, and some for the slab would be
utilized and therefore power exported to load the local grid. All this is there in the system.
The simulation results are showing energy savings, significant energy savings, in two
areas mainly. One is the lighting because we have roughly half the LPD. As you can see
these yellow bars in the standard case are double the height of, nearly double the height
of, yellow bars in the design case. The air conditioning load, the air conditioning cooling
load, is also quite low. It is high in my standard case and these blue bars are low
in the design case.
So if I compare the month by month energy consumption, this line is basically my energy
line as per the standard case. This line is as per my design case.
I come to the summary of the numbers. So if I pay the total energy consumption it is 2,192.40
MWh on annual basis. The purposed case is 1,704.80. All in all we are saving 487 MWh
on an annual basis, which in terms of EPI 194 KWh per square meter per annum was the
standard case, 151 in the purposed case, saving about 22% of saving beyond ECBC level. If
we talk about the demand reduction we could reduce the demand level by about 15%. The
photovoltaic system was able to give us about 16% reduction in energy savings.
This is the monthly generation of electricity from solar photovoltaic plants. As you can
see, the generation is considerably less than 15% only.
Coming to the lessons that we have learned and the summary, whole building performance
method was basically providing us flexibility in decision making based upon the techno-economic.
As I said, one insulation we had reduced and we had stopped even at the lower insulation,
this is required as per ECBC, but as we have gone in some of the things - like glazing,
lighting, and HVAC - beyond the ECBC requirements. Maximum energy savings in our case came to
three areas - glazing, efficient lighting, and HVAC system. Decisions are to be taken
in an integrated manner is what we have learned through this project. Standalone incidence
may give us a wrong picture in terms of payback period or in terms of internal rate of financial
investment and because they influence each other's performance greatly. There exists
a significant potential of exceeding the level of energy building code. Another lesson we
have learned and, this might be useful for the next version of ECBC, that is there is
an absolute necessity of human [inaudible 52:05] of ECBC and we are setting off another
22% annual energy savings potential. Solar Photovoltaic integration was giving us yet
another 15% energy saving. All in all we are crossing 50%, more than 50%, energy savings
level through this building. Before I end I would like to acknowledge the
contributions of Dr. Vishal Garg in improvising the slides of this presentation, Shivraj Dhaka,
and Ashok Dhayal who have helped me a lot in collecting the specifications of this building
and simulating this building.
Thank you very much for your time. Over to you Emily.
>> EMILY EVANS: Thank you Jyotirmay for that excellent presentation. For our final presentation
I will now hand it over to Bhaskar Deol. Bhaskar, if you'd like to take it from here?
>> BHASKAR DEOL: Sure, hi. I'm just waiting for the presentation to come over. Great,
good evening everyone. Thank you so much for joining us this afternoon. Before I start
let me also echo Jyotirmay and the presenters that have gone ahead before me in thanking
DOE as well as PNNL in organizing this webinar. I think we have already had a very good set
of presentations discussing various aspects of the energy conservation building code.
What I thought I would do today is specifically focusing on the experiences we've had implementing
the Energy Conservation Building Code in the state of Andhra Pradesh and then leave my
presentation, sort of finish it off, talking a little about some other work that we have
been doing in the area of energy efficiency, specifically highlighting the financial payback.
The excellent analysis that Dr. Mathur just discussed already makes a very strong case
for energy efficiency in buildings in general and also ECBC. As we will see towards the
end of my presentation, this is also something that our analysis has shown, specifically
when you look at a payback period from the perspective of a building owner or real estate
developer.
Just quickly looking at the agenda for my presentation. I will start off with a quick
introduction to our organization, the Natural Resource Defense Council. I'll focus the bulk
of my presentation on the Energy Conservation Building Code implementation in Andhra and
Telangana states. We've already had very good discussions about the benefits of energy efficiency,
what are some of the key barriers in terms of we heard from Sha, for instance, about
capacity building for ULBs is an issue. Also, the third-party assessors being a model and
also Meredydd also talked specifically about how the building sector is growing. So I would
complement that talking a little bit about how the process of adopting ECBC to a particular
state looks like and how has Andhra Pradesh gone about doing that.
Just a quick introduction - NRDC has been working with the Administrative Staff College
of India. ASCI is a pioneer management and research organization established in Hyderabad
in 1956 and is currently working with the Bureau of Energy Efficiency as well as the
state designated agency in Andhra Pradesh on capacity building for local government
real estate developers and architects about ECBC. At NRDC we have a clean energy and climate
change initiative and building energy efficiency is one of the main areas where we have been
working along with our partners.
Let me just take a second to reiterate what Meredydd already talked about in a good amount
of detail. India has been seeing rapid growth in the real estate sector over the past several
years. We all know that this put significant drain on the electricity grid and what that
means is energy efficiency in buildings is really a low hanging fruit. That is the case
that we are trying to build here. Of course, looking at the key trends that we have been
seeing in the real estate sector wind buildings are slowly gaining in popularity. The Energy
Conservation Building Code is doing its part and a number of states have announced or are
at various stages of implementing it. Then the flip side of it is that in general if
you look at the typical building you do see that there is a trend of increasing energy
intensity. That means that the efforts that our organizations are putting in are very
much required. There is a strong need to make the case for investors or real estate developers
or home owners who are investing in buildings or building houses to focus on what are the
cost savings that can be achieved through efficiency. Then probably appeal to their
desire to have a greater market share if they are real estate developers.
With that let me just jump into the current status of the Energy Conservation Building
Code of Andhra Pradesh and Telangana States. This work really started back in 2009 and
11 and I would really look at those couple of years as laying the ground work for the
state adopting, getting familiarized with the Energy Conservation Building Code and
then starting its process of implementing it or adapting it to the local requirements.
Then between 2012 and 13 was a series of intensive stakeholder discussions but with the government
making a formal announcement that it would start the process of implementing the Energy
Conservation Building Code. I would say key aspects of that period - first of all having
a steering committee, which was constituted of stakeholders that came from the necessary
different groups that included real estate developers, architects, as well as local government,
as well as civil society. And in coming together, to see how ECBC can be helpful for Andhra
and specifically how can that be translated into the local bylaws. We did also have state
bifurcation into Andhra Pradesh and Telangana states, which happened in February or earlier
this year. The advantage of having this process underway already was that as the state had
already announced it would be enacting ECBC both states have now inherited the code. So
that's definitely good news.
If we look at where we are today, that is the green arrow at the moment, the stage where
Andhra Pradesh and also Telangana are at right now is to empanel the architects. Sha touched
upon capacity building for ULBs so this is really the stage where ASCI has been working
with support from the UNDP [inaudible 1:00:28] program to train a number of district officials
and state urban local bodies as well as real estate developers and architects. The target
is the reach 400 stakeholders that would be trained. About half way the trainings have
been completed with mainly the government folks having been trained. Over the next couple
months more trainings will be held for real estate developers and other architects. The
final dates announced for the code being operationalized are August 2014 for Telangana and early next
year, in February 2015, for Andhra.
The next slide is basically to show a little bit of the key roles of various agencies that
come together at the national level, the state level, and the local level in adopting ECBC
specific to a particular state. I won't dwell on this too much but the key methods that
I want to leave the webinar participants with is that it truly is an integrated effort and
one of the most important aspects of it is really how the ECBC is translated to the local
level and how it is kind of tweaked as in where necessary to the needs and requirements
of the local agencies, as well as the real estate developers who interact with these
agencies on a regular basis.
We also had a good discussion about what ECBC constitutes so I will just focus on how the
interpretation of ECBC different than the code announced by the BEE. So first of all,
and this is not really a difference, is that it is applicable to commercial buildings,
offices, hospitals, and IT parks but unlike the ECBC, which has a connected load as the
threshold which figures a building to configure to ECBC, under the base of laying down this
in the square footage of the building rather than the connected load. The main reason for
this was because for the municipal administration department is accustomed with dealing with
building designs. They thought that it would be a lot more comfortable for them to look
at the total area rather than the connected load as something that triggers whether or
not ECBC should be applicable. Of course, the state code takes into account that there
are some building categories, which may not meet this threshold in surface area but would
still be an energy intensive building. So for those there is a special mention in the
code of the government order, which talks about multiplexes, hospitals and hotels needing
to comply with ECBC, irrespective with how large they are. As we already discussed under
our third party certification and validation system and then there is an assessment that
is carried out at two stages. Sha talked about this in her presentation. So, it also specifically
looks at first how to find the design and then having a construction approval, which
then required for the occupancy certificate. I'll talk about that in a minute. The other
key difference is also of the AP ECBC operates a star rating system based on the energy savings.
We have discussed earlier during this webinar the three different mechanisms with which
ECBC can be complied with so developers who choose to go with the whole building approach
can demonstrate that if their buildings go beyond the minimum requirements they get additional
stars for energy savings. Also, if the building goes beyond one star then there is the added
benefit to the developer of fast track approval for their building permissions.
This is what the current building approval process looks like. It is pretty much the
two stage process that I mentioned earlier. First there is a local body issuing construction
approval based on a third party assessment of the building design. Once the building
developer has the construction approval, they go ahead and start the construction. Upon
finishing the construction, they again seek certification by the third-party about the
building being constructed by the design specifications. With that the urban local body issues to the
owner an occupancy certificate and afterwards the building can be occupied. Both the third-party
assessors as well as the urban local bodies are being monitored and pretty much the entire
process is overseen by the state designated agency that's the Bureau of Energy Efficiency
based in Telangana and Andhra states as well as the municipal administration departments.
With that, what are some of the key capacity building activities that are envisioned or
currently being carried out to states? First of all, and this cannot be emphasized enough,
capacity building for planning officials and also elected representatives. There is a series
of programs that I mentioned earlier but also the kind of resources that PNNL has developed
along with Professor Jyotirmay Mathur at MNIT. They are extremely valuable in spreading information
and building awareness and capacity about how local bodies can comply with ECBC. The
empanelment of consultants is an activity, as I mentioned, is currently underway. What
this process entails is having workshops. First of all, the selection of empaneled design
consultants who are architects and can review and provide certification for buildings being
made to specification and then also carrying out workshops and training sessions across
major cities spread across the two states. Some of the cities where these trainings have
been carried out by asking for support from UNDP [inaudible 1:07:48]. Similarly, other
activities, like train the trainers, which were mentioned and Professor Sha and Professor
Mather have been instrumental and also awareness building activities and a couple of pilot
projects. Two that I would flag here is the BEE demonstration project where the Bureau
of Energy Efficiency has extended technical guidance for design of dormant buildings so
that they are ECBC compliant and also pilot project so that they extend support to the
municipal corporation to effectively implement Energy Conservation Building Code.
So here is what the national map looks like of key states currently working or at various
advanced stages of the Energy Conservation Building Code. I do apologize for not having
the interstate boundaries between the Telangana and Andhra.
With that the key take aways and learning from implementing ECBC in Andhra Pradesh,
I would say first of all, in order to create political will it is extremely important to
have senior government buy in for energy efficiency. In the case of Andhra Pradesh the critical
power shortage situation helped create that and then helped generate the momentum so that
there was a lot of alignment within the state of bureaucracy as well as the leaderships.
Energy was really low hanging fruit and could provide significant benefits without any major
upfront costs. The process that Andhra took, which included formation of a steering committee
and also some technical committees brought together key stakeholders, so that included
real estate developers, government officials, architects. Then in that it really ensured
that the key issues of implementation could be addressed early on and that certainly was
instrumental in helping Andhra achieve the speed that which the code was implemented.
Taking into account the local body functioning and I think the example of this is really
how the Municipal Administration Department felt that using a threshold, which was based
on size of building rather than the connected load was useful. Also, the importance of flexibility
both on the part of the municipal departments as well as the government to provide soft
benefits like fast track approvals for projects that were ECBC compliant.
With that I will take a minute to talk a little bit about some of the work that NRDC is doing
along with our partners to showcase the business case for energy efficiency. The way we've
been doing it is really through a series of case studies, reports, factsheets and resources,
which showcase different aspects of energy efficiency. I'll just talk about a number
of buildings that currently exist and have shown demonstrated results and demonstrated
energy savings. The ones highlighted in green have been converted into case studies. I'll
share links to these at the end of my presentation. Clearly as we can see, for each particular
building use building type energy efficiency does provide an attractive investment return
and a quick payback in addition to improved quality, indoor quality, and occupant comfort.
With that, here are the links to the information that I mentioned earlier and thank you once
again and I will turn it back over to Emily.
>> EMILY EVANS: Thank you Bhaskar for that excellent presentation and thank you to each
of our other panelists for everyone’s outstanding presentations today. We have lots of great
questions from the audience. We’ll use the remaining time to answer and discuss. We’ll
get to as many questions as we can. The first question is for Meredydd and Sha.
Is ECBC applicable for 100 kilowatts or 500 kilowatts? The ECBC document says 500 kilowatts.
Which is correct?
>> SHA YU: Thank you Emily. I'll take that question. This is Sha. I think the person
who had the question is partially right. In 2007 the original ECBC does cover the 500
kilowatts and above but there was an update in 2008 and to include the buildings with
100 kWh and above. Right now it's 100 kWh.
>> EMILY EVANS: Thank you. Alright, our next question is - what is the renovation rate
in India for old housing and commercial buildings and how can we improve this?
>> JYOTIRMAY MATHUR: Can you repeat the question Emily?
>> EMILY EVANS: Sure, I'm happy to repeat the question. What is the renovation rate
in India for old housing and commercial buildings and how can we improve this?
>> BHASKAR DEOL: Emily, I'm going to jump in really quickly. I do not have the figures
for this rate in India at the moment for all houses but it does appear anecdotally that
the bulk of the construction activity going on at the moment is focused around new buildings.
What you do see specifically in the housing sector is when a building gets to an age of
about 20-30 years it is more likely that it is torn down and constructed new rather than
being renovated. Other panelists might have another opinion.
>> EMILY EVANS: Thank you.
>> JYOTIRMAY MATHUR: Just to add what Bhaskar was say...Emily, can I?
>> EMILY EVANS: Umhum, please.
>> JYOTIRMAY MATHUR: In commercial buildings what has been noticed over the past few years
is that commercial buildings are doing renovation and retrofitting for two reasons. One is for
aesthetics because now the trend of large glazing and better interiors and so and so
forth they are there. So commercial buildings are going for this reason, aesthetic reason,
but when they are going for retrofitting for aesthetic reasons they are also doing it energy
efficient. Some buildings are doing retrofitting just because there is tremendous change in
technology, for instance, lighting technology has changed a lot, air conditioning has changed
a lot. So they get a business sense of it and that is why they are doing retrofitting.
Recently one IT company approached us and they are doing retrofitting in all of their
6 offices throughout the country. That is just an example of how retrofitting is going
on.
>> EMILY EVANS: Great. Thank you very much. The next question - is there any effort to
improve reporting of public energy consumption data, even if it's at an aggregate level?
>> MEREDYDD EVANS: This is Meredydd. So there are requirements for public buildings, for
new public buildings, that they have to meet GRIHAD standards and that includes some measured
data. So, that is some progress. At the same time I think it is step-by-step because there
are still many buildings without extensive energy efficiency measures and without extensive
metering capabilities.
>> EMILY EVANS: Great. Thank you very much. Alright, our next question is - what are the
market barriers in implementing energy efficiency products and services?
>> MEREDYDD EVANS: This is Meredydd again. So I think that if we flip the question on
its head, building energy codes in particular can serve as a huge driver for building energy
efficiency for the market for building energy efficiency products. We've seen this in many
countries around the world and I think we are starting to see it in India as well when
you look at the glazing market, HVAC market, and household insulation. Obviously cost is
an important issue and codes basically say, look, you need to consider your entire cost,
not just your first cost. To help you with that we are going to tell you what measures
you need to install that will allow you to consider full cost.
>> SHA YU: And just adding to that...
>> MEREDYDD EVANS: Go ahead.
>> SHA YU: A lot of the activities we've done to implement ECBC will also help to address
the barriers in general for implementation to energy efficient products and equipment.
>> EMILY EVANS: Great, thank you Meredydd and Sha. The next question is for Jyotirmay.
Specifically how much is the incremental cost for this project including SPV?
>> JYOTIRMAY MATHUR: Including SPV the project cost is nearly double as compared to a normal
project, which is non-ECBC compliant. For the reason that photovoltaic system itself
costs a lot. In fact, now the costs have come down but when we had ordered the photovoltaic
systems they were relatively costly. So if I redo the project now it would be something
like 1.5 to 1.6 times, including SPV.
>> EMILY EVANS: Great, thank you. The next question that we have is - how can we initiate
ECBC norms in northeast India?
>> MEREDYDD EVANS: This is Meredydd. I think the first step is to adopt ECBC and to make
sure it is included in the local ULB bylaws. So while the state can adopt it, the local
ULBs actually have to insert it and then after that build the capacity to implement it, either
by building the capacity of local urban bodies to check building plans or by allowing private
third-parties to serve that role and building the capacity of ULBs to oversee them.
>> BHASKAR DEOL: Hi this is Bhaskar. I would just like to add to the excellent response
by Meredydd. I would say there is a significant body of resources and information that is
available for any state wishing to move forward with implementing the Energy Conservation
Building Code, both in terms of technical capacity with the likes of Dr. Mather who
is here with us today, Professor Michelle [inaudible 1:20:02] in Heidelberg, and then
a number of others but also just in terms of publications as well as the exact process
that the state needs to go through be it how the implementation should look like, you know,
what all needs to be done in terms of the bylaws. The other thing I would say on that
is also like the experience in Andhra Pradesh showed it is extremely important to have key
local stakeholders come together and really try to understand what ECBC means for the
state and then think through how it would be better to integrate it into the building
bylaws and start from there and use the excellent body of information and resources that's already
there. Through the Bureau of Energy Efficiency, the state bureau agencies, and other organizations
like IIIT and MNIT, ASCI and others.
>> EMILY EVANS: Thank you. Thank you for elaborating. The next question is - are there any provisions
for energy efficiency in electrical installations, i.e. upsizing cable to reduce joule losses.
If so, how are they regulated and how is it enforced and verified?
>> JYOTIRMAY MATHUR: Can you repeat the question Emily?
>> EMILY EVANS: I'd be happy to repeat the question. Are there any provisions for energy
efficiency in electrical installations, for example, upsizing cable to reduced joule losses?
If so, how are they regulated and how is it enforced and verified?
>> JYOTIRMAY MATHUR: Okay, let me try to answer the question. Well, in ECBC there is a complete
section on electrical power and there are broadly you can say three requirements. First
of all they specify the minimum required efficiency of transformers and motors. Then there is
a limitation on power losses. So power cables, if I can remember correctly, the power cables
should not register more than 1% of loss so there is definitely a provision of addressing
this issue in ECBC. There is a separate section in ECBC for addressing this.
>> EMILY EVANS: Thank you very much. The next question is for Bhaskar directly. Could you
elaborate on the set up in Rajasthan...sorry...I'm sure I'm getting it wrong...the ordering of
implementation and it's reporting that have emerged during the 16/17 months of ECBC in
India? Also, please inform how one can become a third-party assessor having cleared the
EAEM Certification of the BEE. I'm happy to repeat that if you need Bhaskar.
>> BHASKAR DEOL: No, sure. I'm guessing that Jyotirmay may want to weigh in on the first
part of the question but do maybe jump straight to the second part. I would say that in the
case of Andhra Pradesh and Telangana states there is an RFP, request for proposals, which
was put out. If an existing organization or an architect is already empaneled with the
Bureau of Efficiency then they automatically qualify as being a third-party assessor for
the Andhra Pradesh state.
>> EMILY EVANS: Great, thank you.
>> BHASKAR DEOL: And I think that the first part of the question was specifically addressed
for Rajasthan so I don't know if Jyotirmay if you wanted to talk a little bit about that?
>> JYOTIRMAY MATHUR: Yeah, so in Rajasthan the mechanism for defining third-parties is
still under development and therefore I am not authorized to say this is the mechanism
but yes, it is going to be pretty much similar to what is there in Andhra Pradesh.
>> EMILY EVANS: Great.
>> MEREDYDD EVANS: In terms of the monitoring and implementation in Rajasthan, so I think
there are a couple of different approaches. Mostly it is ad hoc at the moment because
implementation is fairly new. The Rajasthan Renewable Energy Corporation oversees the
entire system and provides the opportunity for stakeholders to give feedback. There is
some data, as you have heard, about pilot projects on the performance of given buildings
compared to the code, as well as some information on the number of permits being pulled that
are ECBC compliant.
>> EMILY EVANS: Great, thank you very much. Our next question - does ECBC apply to multi-family
apartment complexes that have an aggregate demand of over 100 kilowatts?
>> SHA YU: I think the answer is no. ECBC only applies to the commercial buildings,
not residential for now.
>> EMILY EVANS: Thank you very much.
>> BHASKAR DEOL: Some of the states have actually clarified this. Like in Rajasthan there is
a separate document, which has been released by the government, which is known as Energy
Building Code Directives. There they have spelled out that this is clearly applicable
to commercial buildings, so to say non-residential buildings.
>> EMILY EVANS: Great, thank you. Our next question is - how is ECBC compatible with
ISL 50001 and LEED Green Building Requirements?
>> JYOTIRMAY MATHUR: Well the green building requirements if you talk about LEED rating
system approach is in line but values may not be the same as what they require because
LEED by and large follows ASHRAE 90.1 values rather ECBC has values which are different
than the ASHRAE 90.1 values. So the philosophy is the same but the values may be different.
Whereas, if you go for ECBC rating system, they give an option for compliance through
ASHRAE values or ECBC values. Another fact is that most buildings still go for ASHRAE
building values for ECBC rated buildings as well. There is another rating system, which
is GRIHA rating system, and that other rating system is totally aligned with ECBC. So ECBC
requirements is sort of a prerequisite for GRIHA.
>> SHA YU: Adding to that part of the LEED costs more than other features like water,
land use, and back to the ISL 50001 question. ISL 50001 mostly covers energy management
so that's linked to the operational stage. ECBC covers most of the design stage.
>> EMILY EVANS: Thank you both. That is much appreciated. A final question and I apologize
to the audience. We have more questions than we have time to answer. What is the cost of
construction per meter for the new commercial building? What was the per meter cost for
the MNIT building for the new construction?
>> JYOTIRMAY MATHUR: As I said, the cost of new construction I would request my co-presenter,
architect Tarush, to correct me if I'm wrong. The typical cost of construction these days
for a commercial building is considered to be 2,000 INR per square feet. As for our building,
as I said, it was about 4,000 INR per square foot but I would like to inform that there
were also a lot of restrictions. One was definitely the solar photovoltaic panels. Another was,
because this was an existing building and we were doing retrofitting and the attempt
was not to disturb the functioning of the ground floor when the first floor becomes
functional. Then we shifted to first floor. Then the construction of second floor and
first floor retrofitting wall started. It took much longer and therefore the labor cost,
as well as the material wastage, has been significantly high in this project. So I would
suggest not to take this value as a benchmark value, but this is definitely on the higher
side. If you go for a fresh project it would be much lower than 4,000 INR SVP.
>> MEREDYDD EVANS: In the US typically you are looking at cost, incremental cost, much
greater energy savings than available in ECBC that would be typically well under 10%. It
would be much closer to 5% or actually positive net present value when you look at the lifecycle
cost of those measures.
>> JYOTIRMAY MATHUR: Yes, thank you very much for pointing that out. Our incremental cost
is also for the reason we are going 22% beyond ECBC. If we just stop at ECBC level it has
rightly been said that the incremental cost would not be 10% even. In fact there can be
a net saving if a reduction in tonnage is discounted and that is normally the mistake
that people do. Building costs as the fabric cost and other costs are separate. If everything
has been counted and reduction of tonnage is also counted you may end up saving some
money in the overall cost.
>> EMILY EVANS: Great, thank you both for that answer. It is much appreciated and thank
you all. Now before we take our quick evaluation I'd like to provide the panelists with an
opportunity to provide any additional or closing remarks that you'd like to make before we
conduct the evaluation and close the webinar.
>> MEREDYDD EVANS: I'd just like to say thank you to everyone for participating and we look
forward to staying in touch with several of you. You will see our presentation online
and please let us know. Thanks.
>> EMILY EVANS: Thank you, Meredydd. Great, and now Andrew, if you could please to the
attendee evaluation. I’d like to thank the panelists again and now I would ask the audience
to take a minute to answer a quick evaluation on the webinar you have viewed today. We have
three short questions for you to answer and your feedback is very important to us as it
allows us to know what we are doing well, and what we can improve. The first question
