Analysis of policies to promote weatherization of homes on Martha's Vineyard

A citizen group advocating energy conservation on Martha's Vineyard was the client. The goal was to determine a policy for promoting home weatherization in order to reduce the demand for home heating fuels and the resultant drain from the Island economy. A model of the prototypical dwelling units in New England was modified to predict the benefits to the Vineyard homeowner from different levels of weatherization investment. This was used in conjunction with an analysis of to what extent weatherizing should be promoted and to decide what policies might cause the yearround Vineyarders to further weatherize. With no outside resources, the local Island governments may only be able to adopt a policy to inform Vineyarders of the benefits to weatherization. However, the results of the investment model show that the rate of return an Island homeowner can expect from additional investment is lower than generally expected by the New England household. A plan to inform Vineyarders is less likely to promote more weatherization than similar programs in other areas because Islanders are already aware of the benefits. If the resources are-available, then a rebate program would be most likely to induce further weatheriza-
