Acadia Center Submits Comments to Connecticut DEEP about Weatherization

Weatherization of our residential housing stock will be critical to achieving an affordable clean energy future in Connecticut.

Four years ago the Connecticut General Assembly made a smart move when they required the state’s Conservation and Load Management Plans (“C&LM Plan”) to take steps to weatherize eighty percent of the state’s residential units by 2030. The statute, however, did not include a definition of weatherization, so the Connecticut Department of Energy and Environmental Protection (DEEP) along with stakeholders developed a draft definition in the fall of 2012.

The definition endorsed three possible approaches for defining a building as weatherized: a prescriptive approach (looking for the presence of certain building elements on a checklist), a performance approach (comparing the home’s energy performance against an equivalent modeled home), and a rating approach (using the U.S. Department of Energy’s Home Energy Score). Nothing was ever finalized, however, and two and a half years later DEEP has just recently issued a revised draft of the definition.

The latest definition is much weaker than the first and if approved would not help the state track the condition of its existing housing stock for weatherization purposes. For instance, the definition selects a Home Energy Score value that may allow as much as 60% of existing homes to qualify as weatherized. Worse, homes without wall or ceiling insulation could be considered as weatherized, even though those two building elements are typically viewed as key to any weatherization treatment.

Today Acadia Center issued comments on the definition, recommending that DEEP strengthen it and allow the state to take advantage of all of the economic and environmental benefits that can be achieved through weatherization. Acadia Center’s comments focus on five key points:

 

Weatherization can provide many important benefits to the state’s residents and economy – reduced energy costs, increased energy independence, and less carbon pollution – but only if it’s done effectively, and with these recommendations Acadia Center hopes to ensure that it is.
