Three Years in the Making: Tracking the Progress of Town Weatherization Projects
From 2010 through 2012, the Windham Regional Commission (WRC) worked with towns throughout the region to identify savings for town budgets through municipal building weatherization retrofits. Through both state and federal Energy Efficiency and Conservation Block Grants (EECBG), the WRC’s Energy Committee awarded grants for weatherization retrofits for eight municipal buildings. The successful projects included the Newfane Town Office, Londonderry Town Offices, Grafton Town Hall, Marlboro Town Offices, Weston Town Garage, Putney Town Hall, Windham Sheriff’s Office, and the Windham Superior Courthouse.
Now the WRC is collecting data on the performance of these projects. Data will be collected on fuel oil usage for each of the buildings for the year before the improvements were begun, the year of the improvements, and the year after the improvements were completed. This information will allow us to analyze how much fuel usage was reduced as a result of the weatherization retrofit projects. An example of an analysis is shown below:
As shown, the Weston Town Garage demonstrated a 35.2% reduction in the fuel oil consumption from the years 2010 to 2012. When this usage was adjusted to account for temperature differences between the two years, the reduction in energy use was estimated to be 31.8%. This is a significant reduction in energy use for this building and is an excellent example of how towns completing weatherization retrofits on municipal buildings are seeing savings in the energy bills while reducing their town’s carbon emissions.
