Passive House Incentive Program

The Sponsors of Mass Save® support Passive House construction in Massachusetts. Monetary incentives are offered for multi-family buildings that are four stories or higher that achieve certification through PHI (Passive House Institute) or PHIUS (Passive House Institute US). The incentive payments are staggered throughout feasibility, design and construction phases to reduce the risk a developer may perceive in pursing Passive House certification.

What is Passive House?

Passive House refers to the ultimate goal in high efficiency design: buildings that minimize energy consumption and have added comfort and durability features. Passive House design focuses on air tightness and robust insulation, simplified mechanical systems and high-performing glazing, to achieve significantly lower energy use, while creating a durable and comfortable space for inhabitants. The Passive House Institute (PHI) and the Passive House Institute US (PHIUS) establish two independent standards and provide certifications for such homes: The International Passive House Standard and the PHIUS+ Passive Building Standard.

Is Your Project Eligible?

Multi-family buildings that are four stories or higher with five or more units are eligible to participate in the Passive House Program if they are located within a Mass Save® Sponsor’s service territory and are pursuing Passive House certification. Projects must be enrolled during the early stages of design, prior to reaching 100% schematic design.

Projects must agree to monitor and provide the Sponsors with whole-building electric and gas consumption as well as on-site generation production. Participants must hire a Passive House consultant certified through either PHI or PHIUS to conduct a feasibility study and to serve as consultant throughout the design and certification process. You are eligible to receive post-construction incentives if your building achieves at least pre-certification.
