This exquisite 7-story mass timber development in Boston, MA, was designed to meet Passive House standards and showcase the beauty of cross-laminated timber construction. The building features 42 tons of high-efficiency VRV Heat Recovery Systems, providing simultaneous heating and cooling for 34 residential suites and shared amenity spaces.

Throughout the project, DXS collaborated closely with Haycon to deliver an HVAC solution that met energy efficiency goals while preserving architectural intent. A key design objective was to reduce visible horizontal piping to enhance the aesthetic of the exposed timber. By using a riser-style configuration and the compact footprint of the VRV system, the team was able to deliver clean mechanical integration.

With IEERs in the mid-20s and COPs reaching into the mid-4s, the VRV system—combined with a high-performance envelope—supports full electrification of the building’s heating and cooling. This approach significantly reduces operational costs and helps lower the building’s environmental impact.

DXS supplied the following equipment: 

• 42 tons of Air-Cooled VRV Heat Recovery Systems utilizing a single-port branch box riser design
