Schoolhouse
In 2015, Groton School updated the main academic building, the Schoolhouse, following LEED guidelines when planning the new addition. Most notable was the Schoolhouse's increase in energy efficiency, both through the reinvigoration of the heating and cooling system and efficient lighting fixtures. Geothermal heat pumps under the Circle provide temperature control in the Schoolhouse's new addition, and all lights have motion sensors to turn off after short periods of inactivity.
