Project Background:

The Columbus Commons development will be constructed in two phases. When completed, it will consist of two six -story buildings containing 160 residential mixed-income units and 20,000 SF of ground-level retail space. The buildings will provide apartments that are highly efficient, have improved indoor environments, and are close to the community resources of downtown New Britain. Columbus Commons is very transit-oriented, being across the street from the CTfastrak, where express buses run between Hartford and New Britain as often as every 7 minutes.

Previously located on this site was a police station, and the City of New Britain completed environmental remediation of the site through the CT Department of Economic and Community Developments Targeted Brownfield Remediation Funding.

The project is PHIUS+ pre-certified, which incorporates the DOE Zero Energy Ready Homes program, Energy Star v3.1 and Indoor airPLUS.

Project Services:

Steven Winter Associates is providing Passive House verification for the project and  commissioning services for the building’s HVAC and domestic hot water systems. Through functional testing, SWA will verify that the project’s energy-related systems perform efficiently, reliably, and maintain occupant comfort.

Green Building Features:

  • The high performing envelope includes triple-pane casement windows, R12.5 continuous, exterior insulation, and a continuous air-barrier with enhanced attention to air-sealing.
  • Each unit will have its own air source heat pump (min 11.3 HSPF, 19.7 SEER) and Energy Recovery Ventilation (with up to 88% Sensible Recovery Efficiency) 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.
