Evaluation of Early Performance Results for Massachusetts Homes in the National Grid Pilot Deep Energy Retrofit Program

Published by Building Science Corporation | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-11-01T16:40:39Z
In 2009, National Grid started a DER pilot program that offered technical support and financial incentives to qualified Massachusetts homeowners who planned and successfully completed a retrofit that incorporated the performance requirements and goals of the National Grid DER measures package. This DER measures package, developed through collaboration with Building Science Corporation (BSC), includes specific thermal and airtightness goals for the enclosure components as well as health, safety, durability, and indoor air quality requirements. By providing measures that can be included with common renovation activities such as roof replacement, window replacement, re-siding, basement remediation, and remodeling, this DER measures package is expected to have widespread application for existing homes in the New England area. The post-retrofit performance and cost ranges provided by this research project can provide concrete input for homeowners who are considering a DER. Field test data available for air tightness measured using blower door test.

analyzed. Ten of these homes are single-family homes; two are two-family homes, and one is a
three-family home. The information available for each home that was used in this analysis
included pre- and post-retrofit blower door test results, a project description, reason for doing the
project, and project cost information; and actual post-retrofit energy use information provided by
the utility companies. The post-retrofit energy use for this project was for the 12-month period
from August 2011 through July 2012 and for the 6-month period from January 2012 through
July 2012."
