New Main Library Green Information for Go Green Month


Your new green Cambridge Public Library (with construction to be completed later this year) is expected to be  LEED (Leadership in Energy and Environmental Design) certified by the United States Green Building Council.


Below are just some of the "green" aspects of the project :


  • Bamboo was chosen as flooring for the new rooftop children’s room because it is a sustainable building product. It is actually a grass not a tree and consequently grows very fast and is plentiful. Bamboo grows back in three to five years.
  • We replaced the old open parking lot with an underground garage. By putting the parking underground, we had room for a large landscaped and wonderful new children’s play area.  In fact we could say we created an extraordinary ‘green roof’ for our garage!
  • Many of the windows that you see in the new building do open. The entire front of the new addition is a double skin curtain-wall which is like a giant insulated window helping to warm us in the winter and cool us in the summer.
  • We are using a day-lighting system which has sensors to turn off lights when there is enough light from the sun. There are occupancy sensors in all small rooms that turn off lights when they are unoccupied. 
  • We have used products with no volatile organic compounds (VOCs) commonly found in floor glues and carpet glues, and we are flushing the air of any residue from solvents or other airborne compounds before we open. 
  • The library will use low water flush toilets and sinks with automatic sensors.
  • Our building contractor recycled 96% of our construction waste. Materials such as wood crates, paper, building materials and old stone were set aside for re-use.
  • There is a 350,000 gallon underground water tank by the front entrance that is used to catch storm water runoff from a portion of the city. The tank is part of a large MWRA project to control run–off and reduce localized flooding.
