How feasible is a 25 to 50% reduction, and how much is such a project likely to cost?
The answer to this question depends entirely on the individual residence. In our experience, older homes that have not yet tackled their air leakage issues can make significant reductions through relatively simple weatherization and air sealing measures. The cost of these depends entirely on the complexity of the structure. We’ve seen many examples of projects costing between $2,000 and $10,000 that have achieved 50% reductions in heating energy or more. As more projects are completed under the ME Home Performance Program, we plan to publish real world examples here.
