Project description: Lawrence CommunityWorks, a community-based development group, will utilize $550,000 in stimulus funds to help finance the retrofit of an old mill building that will include installation of efficient air-source heat pump technology, thick insulation, high-efficiency windows, and aggressive air sealing. The finished building will include 125 affordable housing units, a daycare, and commercial space. The building, Union Crossing, will provide a model energy renovation of old mill masonry buildings, a typical building type in the Commonwealth.
