E+ Highland will be built on city-owned land after an intensive neighborhood community process set the development goals, selected the team and reviewed the design. It responds to Highland Park neighborhood’s goals to prevent displacement, provide current neighborhood residents a homeownership path, and be Boston’s most sustainable neighborhood.

To prevent displacement of current residents and support their economic mobility, E+ Highland is 100% affordable: all 23 units at 30 to 60% AMI in a limited equity co-op. Low-income residents build financial equity with no money down while affordability is maintained for future residents. 

The façade features a masonry and wood-like material palette reflecting the surrounding homes. A dramatic canopy shaped for PV array welcomes residents and visitors. Community amenities include a gallery/gathering space and adjacent patio for neighbors and residents to share and a public path and stair that links neighbors up and down Fort Hill to area parks and public transit. 

Daylit units feature large operable windows and red-list free finishes selected for occupant well-being, beauty, and durability. All-electric systems with energy recovery ventilation provides a healthy indoor environment, removing pollutants and irritants. 

Designed to achieve net positive energy, LEED Platinum, Phius, and ILFI Zero Energy Certification, E+ Highland will provide resilient, healthy, and affordable family housing. 

Technical advancements to meet energy-positive and resiliency goals include airtight passive building techniques, optimizing window/wall ratio, and targeting a thermal-bridge-free enclosure. The hot water system uses CO2 refrigerant with zero Ozone Depletion Potential. 

Renewable energy is maximized with a high efficiency rooftop PV wave rack system. Residents will have minimal utility costs and maintain comfort for 5+ days in a power outage.
