Thank you, Mr. Martin, and ladies and gentlemen. I appreciate the opportunity to address you today.
I have a real passion for energy efficiency in buildings. The fact that you're looking at this and taking it seriously is a major step forward. I think that's actually where the federal government should be. We need leadership in how we treat buildings.
As we go through this, I look back and reflect that I got involved in energy efficiency in buildings over 30 years ago. I also represent Canada on the international scene at the International Organization for Standardization. We go to countries all around the world, European countries, Asian countries, and so on. When I first got involved with ISO, when you went to meetings, because you were from Canada you were automatically considered to be an expert. The National Research Council was one of the leading research institutes in the world.
We have an excellent base we're building our buildings from, and we're working on how to make them better. Unfortunately, we're losing that in a lot of cases, and we're no longer the leader in how we build and renovate buildings. Countries like South Korea and Thailand are actually ahead of us in getting some things done. I think we still have the opportunity to show leadership and show not only the citizens of Canada but also the world what we can do.
As a side note, I was on a conference call this morning with some people in Sweden. This is a project in which we're taking some of our energy efficiency projects to Scandinavian countries. One of our partners is an American-based company. He asked how it was going to be viewed in Sweden. The short answer was that it wasn't going to be that well received. They basically had the opinion that Americans don't know how to build buildings. That wasn't necessarily unusual or anything different, but then he went on to say that if you say you come from Canada, well, it's cold in Canada and you absolutely know how to build buildings. I was very heartened by that this morning, because it tells me we haven't quite lost everything.
When we take a look at energy efficiency in Canada, we have always said that we are a big country so our energy use is high compared with other countries. When we take a look at how we can reduce energy use in Canada, and this applies right around the world, buildings become the number one spot. If we're going to transport materials and goods across Canada, there are so many kilometres they have to go and we can make our trucks more fuel efficient, and those sorts of things, but when we get down to kilowatt hours and gigajoules, or whatever it might be, the biggest opportunity we have is in buildings. If we start to look beyond that into the environment and sustainability, I propose that the greenest building there ever is, is a building we don't build.
As we're looking at new construction, obviously we want to make it the highest quality in energy use and so on, but also we want to retrofit our existing buildings. Whether they're 10, 50, 100 years old, it doesn't really make any difference. We can retrofit these buildings, and we can save energy and solve all the issues we have with destroying buildings and building new ones.
Mr. Martin, as you mentioned, our office is in Winnipeg. We're in the downtown core. The building my office is in is over 100 years old. Most of the buildings around there have now been retrofitted and brought up to date. If we can make them energy efficient, that's great.
There are other things that we don't sometimes attach to energy efficiency in buildings.
About 40% of the garbage that goes into landfill is construction waste, so we're going to have a reduction there.
I am at a conference here in Indianapolis, and one of the presenters last night brought forward the issue that when we create energy.... We have a lot of hydro power in Canada, and we're very fortunate in that, but we still do coal and gas. On the American side, of course, it's much more. They don't have quite the same percentage of hydro power. For the southern Unites States, the amount of water used to produce electricity is equal to all the water that goes over the Niagara Falls on a minute-by-minute, second-by-second basis. One of the points he brought up is that as we expand the population and so on, people like it where it's warm. They're moving to places like Florida and Georgia. Those are the areas where it's the hardest to get water. We have some environmental benefits to do energy efficiency in buildings that go beyond just reducing the energy and reducing our costs.
Back to the potential, obviously any new building we build should be absolutely the lowest energy use that is possible. The terminology typically used today is “near net zero”. What we have to keep in mind is that of the existing buildings, 74% of the buildings we have were built before 1989, and 93% of the buildings we have out there were built before 2003. The potential we have for reducing energy use in buildings, federal government buildings or whatever, is phenomenal on that side.
As you move forward and you're looking at improving the government buildings, first of all, we should be setting an example with use of technology and efficiency and setting standards for energy use to show the industry and to help the industry move in that direction. We're doing that through the codes in some of the other areas, but that's a long, slow process. We need somebody out front to lead the pack there.
My company has started a project called Historic Zero, just because our buildings happen to be 100 years old. We're going to be renovating three buildings in downtown Winnipeg. Our whole purpose for doing this is to show that you can take a historic building, which would be considered the hardest to improve in energy efficiency, and bring it as close as we can to near net zero that's out there. We've been discussing this project. We have Manitoba Hydro involved. We have interest from BC Hydro. We have interest from a lot of architects and engineers in both Canada and the United States because we don't have any program out there that deals with existing buildings.
We've established 100 equivalent kilowatt hours per square metre per annum as the goal that we're trying to hit. That's another thing I would suggest be brought into the foray of dealing with government buildings: we should be setting energy targets. We should not just simply be adding some materials or changing motors or changing light bulbs, or whatever it might be, but we should actually bring it down to energy use intensity. Whether 100 equivalent kilowatt hours per square metre is the right one for government buildings or not, it will all depend on use, but if we don't have a target to go to somewhere, we're never going to get there.
An example of how that can happen is that the Army Corps of Engineers are renovating a lot of buildings in the United States. They have set, for example, for airtightness, when they renovate or build a new building, that building needs to be airtight to the point where the amount of air leakage in and out of the building is going to be about 1.25 litres per second per metre squared, at a 75-pascal pressure difference.
Now a typical building would be somewhere in the neighbourhood of 10, 15, 20 litres per second. To keep it very clear, when you build or renovate that building you do not get paid unless you meet this performance requirement, which is an extremely airtight building. When they first brought this out as a performance requirement it was deemed impossible, that nobody could do it. Now it's being done very routinely, and in fact they've moved from 1.25 litres per second per metre squared down to less than a half a litre per second per metre squared. The point of all that is just to show what happens when you start to set some targets, that not only can you achieve the target, but you can go beyond.
As an example, again, when we mentioned the 100 equivalent kilowatts hours per square metre per annum to architects in B.C., in Vancouver, where I had some meetings last week, they said that's nothing for them to achieve, they're currently achieving that today. So it shows where we need to go.
Now, obviously we do the standard energy-efficient things that we've done for the last 20 years, the light bulbs, the motors, the controls, and so on, but we need to get into some areas that we haven't got into. On a typical building we haven't worried that much about the air leakage. We're now realizing that air leakage accounts for somewhere around 30% of the energy loss due to air leaking in and out of buildings.
We haven't applied that. We've left the building envelope alone. We're starting to understand continuous insulation. It's extremely important that we get rid of the thermal bridges so the building will perform much better, rather than just throwing some vacs in the attic or vacs in the walls.
We need to also look at new and innovative products. We have a lot of new materials coming up. We have vacuum insulated panels. We have high-performance insulation. We have aerogels. We have high-performance equipment, and the list goes on. We need to start to take a look at how that can better us.
A quick example is a thermostat called Nest. It was designed by people who used to work at Apple. It's very simple, but it learns what you do. We're probably all aware and familiar with the setback thermostats, but this goes way beyond that. People who have installed it in their homes have seen their energy bills drop. We have to take that type of new technology, which is basically a smart thermostat, and apply it to some of the areas that we're dealing with.
