Retrofitting vacant and underutilized historic buildings to Passive House Institute US (PHIUS) standards leverages an existing building’s embodied carbon, which combined with low carbon and carbon storing materials, can transform our historic buildings into carbon sinks - a good thing! With careful consideration, the Federal Historic Tax Credit Program (FHTC) can provide an additional source of funding for these ambitious Passive House projects. 

At its July 15th convening, the Energy Cohort, a peer learning group co-convened by LISC Boston, MACDC, and New Ecology, featured a presentation by Heather Clark of the Rocky Mountain Institute. Currently under construction, Moran Square, in Fitchburg, is one of the first affordable, PHIUS, Historic Tax Credit projects in the U.S. The site includes a historic firehouse, a vacant lot, and historic three-story building. The presentation covered how the team managed to meet the rigorous historic requirements of the FHTC Program, while achieving ambitious PHIUS and low carbon construction goals.
