Weatherization of homes: what methods and costs?

The “weatherization” of 2M American homes is part of Presidental candidate, Joe Biden’s proposed energy policy. The aim is to reduce energy costs, consumption and emissions.

Hence, this data-file estimates the costs and payoffs of five different weatherization methodologies: attic insulation, air sealing, window upgrades, window coverings and smart thermostats.

We find the most cost-effective options are smart themostats and air sealing. Ballpark numbers, further details and implications are explored in the data-file.  This adds to our recent work on the decarbonization of heat.
