Project Background:

Columbus Commons is a six-story building with 80 mixed-income apartments and 11,552 square feet of ground-level retail space located across the street from the New Britain CTfastrak station, where express buses run to and from Hartford as often as every 7 minutes. The residential units are highly efficient, have high-quality indoor environments, and are close to the community resources of downtown New Britain.

A police station previously sat on the site of Columbus Commons, and the City of New Britain completed environmental remediation of the site through the CT Department of Economic and Community Development’s Targeted Brownfield Development Loan Program remediation funding.

Project Services:

SWA provided verification and sustainability consulting services for the project as well as commissioning services for the building’s HVAC and domestic hot water systems. Our consultants will test and verify that the energy-related systems perform efficiently and reliably and maintain occupant comfort.

The project is PHIUS+ pre-certified, complies with the DOE Zero Energy Ready Homes and Indoor airPLUS programs, and is ENERGY STAR v3.1 labeled.

Green Building Features:

  • The high-performing building envelope includes triple-pane windows, R12.5 continuous exterior insulation, and a continuous air barrier with enhanced attention to air sealing.
  • Each residential unit has its own air source heat pump (min 11.3 HSPF, 19.7 SEER) and energy recovery ventilation (88% Sensible Recovery Efficiency (SRE)) with MERV 13 filters capturing airborne particles and allergens less than one micron in size, such as pollen, fine dust, pet dander, mold spores, and bacteria-carrying particles.
