and the International Energy Agency. Today we're very fortunate to have Didier Houssin

and Marc LaFrance joining us. Our speakers will focus on IEA's Energy Efficient Building

Envelope Technology Roadmap

And one important note I've mention before we begin our presentation is that the Clean

Energy Solutions Center does not endorse or recommend specific products or services. Information

provided in this webinar is featured in the Solutions Center’s resource library as one

of many best practices resources reviewed and selected by technical experts.

And I just want to go over some of the options for audio in today's go to webinar. So the

audio you have two option. You may either listen through your computer or over your

telephone. And if you choose to listen to your computer, please select the "mic and

speakers" option in the audio pane. Doing this will just eliminate any feedback and

echo and if you select the telephone option, a box on the right side will display the telephone

number and an audio PIN that you should use to dial in. And panelists you just have to

please mute your audio device when you're not presenting. And if anyone has a technical

difficulty through the webinar, you may contact or go to webinars Help Desk and that phone

number is at the bottom of the slide, that is 888-259-3826.

And we encourage all attendees to submit any questions that they might have throughout

the webinar. You may do that by submitting the question through the question pane and

that is in the go to webinar window and if does anyone have any difficulty viewing the

materials through the webinar portal, you will find PDF copies of the presentations

at http://cleanenergysolutions.org/training and you can follow along with the speakers

present. Also an audio recording in the presentation will be posted to the Solutions Center training

page within a day or two of the webinar.

We have a great agenda prepared for you today that is focused on the Energy Efficient Building

Envelope Technology Roadmap detailed and strategies and actions to transform the way building

has constructed by 2050. Now before our speakers begin their presentations, I'll provide a

short informative overview of the Clean Energy Solutions Initiative and then following the

presentations we will have a question after session where I will present any questions

from the audience through the panelist and then we'll wrap with closing in a very brief

survey.

Now this slide provides a bit of background in terms of how the Solution Center came to

be. Solution Center is an initiative of the Clean Energy Ministerial and then supported

to a partnership with UN Energy. It was launched in April of 2011 and is primarily led by Australia,

the United States and other CEM partners. So outcome to this unique partnership includes

support of developing countries, the enhancement of resources on policies relating to

energy access, no cost expert policy assistance and peer to peer learning and training tools

such as the webinar you are attending today.

So there are four primary goals of the Solution Center. Served as a clearinghouse of clean

energy policy resources. Also serve to share policy best practices, data, and analysis

tools specific to clean energy policy and programs and the Solutions Center deliver

dynamic services that enabled expert assistance, learning, and peer to peer sharing of experiences

and then lastly the center foster dialogue on emerging policy issues and innovation across

the globe. So our primary audience is energy policy makers and analysts from governments

and technical organizations in all countries. And then we also strive to engage for the

private sector, NGOs and civil society.

Now, one of the marking features that the Solution Center provides is its expert policy

assistance. This is known as it Ask an Expert and it's a valuable service operative in the

Solution Center at zero costs. So we have 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. For example in the area of buildings we're very pleased to have Cesar

Treviño, Leader of the Mexico Green Building Council serving as our expert. So if you have

a need for a policy assistance on building or any other Clean Energy sector, we encourage

you to use this useful service.

Again, this assistance is provided free of charge. So to request assistance, you may

submit your request by registering through our Ask an Expert feature at http://cleanenergysolutions.org/expert.

We also invite you to spread the word about this service to those in your networks and

organizations. So, in summary we encourage you to explore and take advantage of the Solutions

Center resources and services including the expert policy assistance, subscribed to our

newsletter and participate in webinars like this.

And now I'd like to provide a brief introduction for our expert panelists today. Our first

speaker is Didier Houssin, the Director of Sustainable Energy Policy and Technology at

the International Energy Agency and then following Didier, we will hear from Marc LaFrance of

the International Energy Agency also known as Sustainable Policy and Technology Energy

Demand Unit and with those introductions, please join me in welcoming Didier to the

webinar.

>> DIDIER HOUSSIN: Good morning everyone and I'd like welcome everyone to this webinar

and also I'd like to thank the Clean Energy Solutions Center and the National Renewable

Energy Laboratory for collaborating with us today to launch our new technology roadmap

for energy efficient building envelop. Achieving significant energy and due to emission reduction

in the building sector is a very ambitious goal. This publication wants to address the

fundamental challenges and opportunities to transform the way it was constructs and renovates

building. ETP 2012 as you can see on this chart identified the low carbon energy technology

that can help achieve the 50 percent reduction from today while avoiding all of the expected

increases. The most important option in both the short and the long term is improving energy

efficiency. Improved energy efficiency in the annual sectors accounts for 38 percent

of the total emissions reduction in 2050. Today's publication is focused on how to construction

buildings which is one of the largest factors impacting heating and cooling loads and for

most of the world, heating and cooling loads are the largest end users. Our next upcoming

ETP 2014 publication will be released this coming spring and it will focused an increase

use of keen electricity so for the building sector ETP 2014 will analyze greater tool

switching from gas boiler to heat pumps, the two regions in particular for China and [inaudible]

[00:07:24]Union.

Let me come back to the global challenge. As you can see on this chart, has all end-use

sectors, buildings is the largest energy consumer accounting for 35 percent of total energy

used just before the industry and transport sectors. Policies try being to reduce energy

and fuel emission must address the growing energy needs of this sector. As you can see

on this chart, the breakdown of energy, the consumption in the building sector shows that

the share of electricity 28 percent and renewable including tradition biomass 30 percent.

>> SEAN ESTERLY: Sorry Didier. Okay, there you go, it's working, yup.

>> DIDIER HOUSSIN: The importance of the building sector it got obvious. It represents 1/3 of

carbon emissions and it is strongly correlated to its used of around 50 percent of the total

electricity consumption in the world, much of it from the burning of coal. The building

sector plays a vital role in the global economy and for instance in the global economy crisis

and stagnation described it has been to a logic sampling to the building sector collapse

in many countries such as Spain and Europe. Buildings remain in service for a very long

time in where they constructed inefficiently that lost opportunity will cause problems

the decade and even centuries to come. So getting construction right the first time

its fair amount along with the need to upgrade the existing building stock. The demands for

new building will continue to grow for quite sometime with increasing population and wealth

at global level and especially in developing market.

Our recent major publication on buildings that we published earlier this year lays out

strategy to say 80 joules which is 25 percent less than in our business as usual case, our

60 week scenario and this amount is equivalent to the combine consumption of India and Russia.

These publication provide 9 regional analysis including detail recommendations. It also

provide comprehensive technical analysis and recommendation for the food compliment of

technologies and end users in the building sector including a plan on how to implement

energy efficiency alternative at a range from on the to deployments. Integrated policies

such as building codes and deep energy renovation on a major focus along with the efforts needed

to transform niche products into mainstream and its practices. That led me now come back

to the next please to the -- our technology roadmap program. This program was launched

for -- at the request of the G8 in 2008 and to objective is to accelerate the development

and deployment of the major clean technology that are needed to reach the ambitious goal

of limiting global temperature increases to 2 degrees Celsius. Our roadmaps aim to address

three main question where we are today for a particular technology, how do we move forwards

and what are need term action to get us there. This approach is important in the sense that

it involves engaging experts from industry, government, academia and research to work

together in developing an implementable strategy to accelerate the development and deployment

of a particular clean technology. We have issued two previous roadmaps in the building

sector, one on heating and cooling equipment and one in solar heating and cooling.

We also have developed in the feel of clean energy policy pathways that assist policy

makers in the tuning more effective policies targeting for critical areas within out top

25 energy efficiency recommendations. We have previously issued a pathway on building energy

performance certificates and this year we issued a new one on how to modernize building

energy coals. So today, a roadmap on building envelop is really complimented it's previous

work of the IEA dedicated to the building sector. So they keep on hear as if this new

IEA roadmap lays out the strategy to transform how buildings are constructed around the world

including the technical, economic and policy analysis to help policy maker focused on the

construction market that can also reenergized their economy. Several regional assessments

are provided to assist decision makers on where to focus their efforts and calls for

to improve tracking of progress on the adoption of high priority building envelop materials

and products. The roadmap also calls the policy makers to conduct self evaluation on key policies

related to initiating more sustainable building practices. It also lays out few recommendations

to each stakeholder group that each of these groups should follow to ensure the opportunity

it relies while at the same time avoiding construction with inefficient materials to

continue. Having said the global objective of this new roadmap I'd like now to turn over

to Marc LaFrance and with the main author of this roadmap and he tell you more about

the specific content and recommendation. So please Marc.

>> MARC LAFRANCE: Thank you Didier. Welcome participants I appreciate your taking the

time to tune in today to learn more about --work on the building energy, a building

envelop of roadmap. So here on this chart, this basically lays out the transformation

for building and on the left it represents the majority of the building stock that exist

in the world today, that is very inefficient and then in places such as Canada, the EU

and US we have what we call no advanced construction with a lot of technology such as insulation

and low-e windows and proper air ceiling but we really want to move to right which is the

future for zero-energy buildings and how can we optimize performance through technology

such as highly setting windows, advanced façade, no day lighting, stole and thermal, that sort

of thing. So the entire roadmap lays out this process of how do we move forward.

Okay, and so this shows the potential savings from advancing building and we have some globally

and we have 8 regions lays out here. And look the largest savings come from EU, Canada and

United States, China and Russia and also with mostly for heating. So, we have the largest

consumption of the world right now with heating mostly in the residential sector, that represents

the largest opportunity for savings but actually the largest growing sector is the cooling

demand and a lot and many developing countries that's going assuming fast so that also have

to be addressed. So we have technologies and policies that address both the heating and

cooling savings.

So, now I'm going to go through a few technical detail then I won't go in too much but just

to give you a flavor of what the roadmap has to offer. So here is the chart that shows

the performance of the golden rules and the majority of buildings are there, very inefficient

with the existing stock that have virtually zero-insulation and then building that have

let's say we'll call it minimal insulation from the 60 and 70 and then we have some very

advance building codes in the world to show you where we can get to and so the IEA is

laying out recommendations for both cold and hot climates although we know that these deficients

have to be based at the local and regional level with local and regional data such as

pricing and cost materials.

Okay, another key element is to have air sealing and if any building is going to have a mechanical

equipment for conditioning either heating or cooling it should be air sealed and contrary

to many people believe that air sealing causes poor quality it actually completely the opposite

through and by properly sealing the building and controlling for fresh air ventilation

you can actually improve air quality not degraded and the savings are pretty dramatic so this

is something that needs to be pursued more actively and even with lots of accept in Europe

with energy performance certificate the majority of those do not require a validated air leakage

task which is something that needs to be pursued.

Okay, in this chart shows you the performance of Windows and on the left that's the majority

of the stock of windows that exist in the world today. Lots of single pane glass with

inefficient framing even double clear glaze glass is inefficient and so today in lots

of places with advanced building codes, people are pursuing window performance that approximately

1.8 watts percent meter squared Kelvin or the technology is double pane with low-e glass
