We hear these words from every direction these days. What can homeowners do beyond resetting the thermostat? Many focus initially on alternative energy sources such as solar. While solar, geothermal and even pellet boilers are possible pathways to reducing energy use, these choices are quite expensive compared to the cost of meeting a higher energy conservation standard during the building process. Homeowners, builders and government officials seem to have forgotten the maxim: the cheapest energy is energy never used. The first step to addressing high fuel bills should be energy conservation. An airtight home with controlled ventilation can be achieved easily, and fairly cheaply, by using ultra high R-value insulation and air sealing. If this is added before enclosing the walls, energy use for heating and air conditioning can potentially be reduced by a whopping 40-50%. When added to the attics and basements of existing homes, significant annual savings can be realized. Building codes need to be changed quickly to mandate that all new homes and renovations be built to meet the Energy Star standard or higher. But let’s not wait for our federal, state and local governments to take action. We are all part of the problem and we can begin conserving energy now. Even in the absence of code changes, homeowners and builders must choose to caulk and seal homes and install very high R insulation such as blown in cellulose or spray foam, particularly during any kind of construction project.
