Nearly one third of Massachusetts’ total carbon emissions come from its more than 2 million existing buildings. It is essential that these buildings are retrofitted to be energy efficient, healthy, and resilient. While long used in new construction, the Passive House standard is just as effective for existing buildings and can be the key to reducing their emissions.

To do this, owners, contractors, and financiers all need to understand and prioritize the PH standard, new heating/cooling solutions, electrification, and deep energy retrofits. Throughout 2022, PHMass will be providing resources and presentations to meet this challenge. Join us and ensure that all of our buildings, new and old, are affordable to heat and cool, sustain our health, and become part of the climate solutions we need to meet required emissions targets.


Sept 13th
Join us for our September open meeting as we continue to discuss Passive House retrofits. This month, we welcome Ryan Merkin, VP Business Development at BlocPower to speak about their approach to scaling existing building retrofits - through services to building owners, including turnkey design, project management and implementation to financing as well as program services to cities and utilities, including our building electrification enterprise software, workforce development services and outreach models.
