Concord Free Public Library Designated as First Certified Sustainable in MA

Congratulations to the Concord Free Public Library on achieving sustainable certification through the Sustainable Libraries Initiative’s award-winning Sustainable Library Certification Program (SLCP). The CFPL is the first library in Massachusetts to successfully achieve this certification. We are very happy to have played a part in this important recognition.

Here are some aspects of our design of the extension (and other updates) that helped with sustainability:

  • Robust building envelope (walls 30% / roof 55% better than Code)
  • Energy savings of 80% compared to baseline, with possibility of zero emissions once fossil fuels are eliminated from the electric supply
  • Wood structure (stores embodied carbon)
  • Adaptive reuse of a 1790’s building with envelope improvements to reduce energy use
  • High-efficiency all-electric, fossil fuel-free HVAC system (air source heat pumps)
  • Natural ventilation where permitted by Code
  • Passive daylighting
