Off the top, without getting into huge discussions, certainly it would be to look at all areas of products, from shower heads all the way up. I think part of the program is big dollars and big investments by the homeowners. I think we need to cast our net much wider.
We also need to be more demanding of our manufacturers and suppliers that they are creating new products, being more innovative with ways that we can retrofit homes. Many of the products that are available are only available because of the new home construction area.
Also I think it's important that homeowners see the value in retrofitting their homes. I'm not sure that an 18-month window is long enough for people to see the benefits of what they've invested in. We had a mild winter this past year, so everybody's gas costs went down. Great. Is that because they bought a new furnace or because of Mother Nature? So I think the program needs to have a longer period of time.
Clearly we need to be looking at the entire house as a system. You can't tighten up building envelopes significantly without putting in HRV, heat recovery ventilators, or some mechanical ventilation system. Over the years, that's one of the lessons we've learned in new homes, and I think that's key.
