For the BrightBuilt Retrofit, we talk about a Deep Energy Retrofit – generally understood to be a reduction of 50% or more in energy use. This is great for those who can reach this far but for most homeowners and businesses, a less aggressive undertaking is more logistircally and financially realistic. Weatherization is the name often given for a lighter energy efficinecy push – it may include such efforts as extensive air sealing, attic insulation, tightening windows and efficient lighting.
The American Recovery and Reinvestment Act devotes a good bit of energy and finances to weatherization of existing homes in the U.S. After spending quite a bit of time on the web, I’ve been seeing a host of different numbers, from $5 billion specifically dedicated to weatherization services for low income families to $80 billion total for weatherization related investments. Several government sources refer to average homeowner savings of around $400/ month based on anticipated investments but I’d also like to see this number given in reduction of heating loads by insulating (kBty/sf/yr) and even in pounds of carbon saved.
