Ian MacDonald, P.E., Principal and Mechanical Engineer at Allied Engineering presented at a recent NESEA Pro-Tour session held at the beautiful new Maine Coast Waldorf High School in Freeport, Maine.  This building is the first Passive House/Net Zero High School in the U.S.

Some of the sustainable engineering system design features include:

  • Interior LED lighting tied to “occupancy sensors”
  • Air source heat pumps for efficient heating and cooling.
  • Energy Recovery Ventilators (ERVs) use the exhausted air to precondition the incoming fresh air to minimize energy loss
  • Roof mounted solar panel array is sized to produce at least as much electricity as the building is projected to use.
