Energy Audit Action Steps Female: It is action step time, so Gary presented us some beautiful information on what his findings were. And now, it is time to take this to the owners and say, “This is what you got to do to make the changes, make your home more green and energy efficient.” So, tell us what we got to do here. Gary: As I mentioned earlier, the air infiltration on the building is probably a single one biggest thing that can be tackled here. And in this particular case one of the big fenders was the way the furnace system is installed in the house. It is in the 2nd floor in a closet, the closet doors, are air sealed for the rest of the house. And as this is required by code, there are two six-inch diameter pipes that are connected to the attic to provide combustion air for the furnace. And the water here which is in there and that is good but also since these doors have large gaps, basically that means we have these two six-inch diameter holes directly connected to the attic year route. Female: Because you got a hole in the ceiling, the big pipe coming down, this is for the layman like me. The big pipe coming down and then two just basic folding doors like you find in a closet or something like that making holes everywhere and stuffs so you’ve got freezing cold attic, temperature which we saw from the infrared camera and then open door. Gary: And then heat rises so it is just going out into the attic. And that is why we just have those high heat— Female: So what do they have to fix that? Gary: So, the fix is in this from this case I think the most cost effective fix will be to, since the furnace is still relatively new, there is nothing wrong with it, same with the water here, you have to have the combustion there so you want to replace those doors with some exterior great doors that can be air tight, sealed from the rest of the house. With a threshold—because that closet is to be considered outside and that will stop a large amount of air. Not all of it but still a big part. Female: And let me ask you this too because this is kind of a side note but in terms of being an energy auditor and seeing that behind scenes from what is being built, do you see the awareness. I mean that would have been a very wonderful thing to have done to build the home or things changing in the direction of being able to—? Gary: They are changing slowly. These types of mistakes are still being made in the new homes unfortunately. And not where you can put it, it would make the progress but there were still a lot of problems out there. Female: Gary is wonderful to have, to educate and that is why we hooked up with him. Gary: Thank you. Another aspect of this is that there is a potential here for some health and safety issues. And that is why I am putting bold type on this report that no air ceiling measures should be done on a house until this particular problem is resolved because if you get a house that is too tight with this kind of condition, with appliances, having combustion air requirement and venting, if the house becomes too tight, you can have a condition where the gas pipes will back draft, which means carbon monoxide coming into the house which is highly hazardous so that is why we take special— Female: That is step one that is why that is step one. Gary: That is why it is step one and there is a bold print and it is very important that things are done properly and completely. So, you don’t have issue. So, that is one of our big ones. Beyond that, we’d go rather quickly on seeing the measures we can do to air seal the house. Any penetrations that we can get to in the second storey ceiling which joins the attic such as candle lights but they are not an air tight fixture. That is rated that way, it is a large source of air leakage. All electrical boxes for ceiling light fixtures, switches, perceptibles. Female: Like you’ve said. Gary: Right. Female: Do at home, do it something. Gary: The windows are pretty good but the gaps around
