Artist James MacNeil Whistler's birthplace home in Lowell, Massachusetts, was built in 1823 and now houses the Lowell Art Association. The house was in need of a series of upgrades that improved energy efficiency while catering to the specific needs of a historic home and museum. Through the BetterBuildings Lowell Energy Upgrade program, the historic house will receive upgrades that include a high-velocity, small-duct HVAC system, updated storm windows, and attic insulation. These upgrades will reduce humidity in order to preserve the artwork displayed, and catch up to modern electrical demand without sacrificing the home's historic characteristics—all while providing energy savings of more than 30%. To learn more about how the project was financed and further details on the innovative HVAC equipment, read the original post from Lowell's Office of the Mayor's blog.
