Pro Tour: Electrification and Exterior Insulation of Occupied Historic Renovation

Summary

Learn how a historic reno in Attleboro, Massachusetts electrified heating and cooling and leveraged Historic Tax Credits to upgrade insulation.

When November 20, 2026 1:00-5:00PM

Join NESEA for a Pro Tour of an occupied 19th century factory building undergoing a re-renovation and electrification using historic tax credits.

There are numerous points of interest in this project, including updating to air-to-water electric heating and cooling with minimized refrigerant distribution. Previously, the central system provided heating only to the residents and the maintenance team had to chase leaks seasonally. The gas boilers resulted in high operational impact and cost and ederly residents endured summer heat without cooling in their apartments. The project converted this out-dated, problematic, leaky, fossil fuel boiler system to an electric heat pump system. To minimize refrigerant distribution through the building, the project employs an innovative air-to-water heat pump system with a modular refrigerant-to-water exchange (HEX unit) plant. The project configured equipment in a novel way to allow provision of both heating and cooling to all residents at a much lower impact than the previous system. Additionally, the project team utilized the seemingly impossible combination of Historic Tax Credits and exterior insulation to improve the building’s envelope.

Our day will start with an opening presentation from the project team, including the developer and architect, where attendees will learn about the history of this renovation, the vision for the extensive the high-performance work being done there, and the complex financing strategies. Attendees will then break into small groups to tour the building while hearing more from the interdisciplinary team of experts who made it possible. After the tour, we’ll regroup for a reception and Q&A, giving attendees the opportunity to chat with the day’s speakers and each other.
