Our project at 288 Harrison Street is PHIUS+ CORE Pre-Certified by Passive House Institute US!

This multifamily, new construction project will significantly add to the affordable housing stock in the Chinatown neighborhood of Boston, transforming a current parking lot into a building that is respectful of its surrounding context and is a gateway to the neighborhood. The sustainable design prioritizes measures that minimize the impact of energy consumption and high-temperature events, including high performance building envelope and windows, energy recovery, a light roof with high solar reflectance, high-efficiency HVAC equipment, and careful attention to mitigate against air pollution.

The PHIUS+ Certification Program is the leading passive building certification program in North America. It combines a thorough passive house design verification protocol with a stringent Quality Assurance/Quality Control (QA/QC) program performed onsite by highly skilled and specialized PHIUS+ Raters and Verifiers. In certain circumstances such as high unit density, it’s problematic to meet the PHIUS+ 2018 targets on-site. For these cases, PHIUS now offers PHIUS+ Core. PHIUS+ Core retains PHIUS+ 2018’s conservation target, but enables project teams to certify utilizing only on-site measures. Learn more.
