Groton Municipal Building

Groton Municipal Building is a mixed use facility that includes offices, an auditorium, and a data center. Karpman Consulting performed a calibrated energy simulation in support of an energy audit, with the goal of evaluating cost effectiveness of various energy efficiency upgrades to the building. The measures considered included:

• several alternative room insulation approaches

• several alternative HVAC systems, in

• exterior wall insulation

• upgrades to below-grade walls

• window replacement

• several alternative lighting measures including installing high performance T8s, LED, and reducing number of fixtures in spaces with excessive lighting levels 

• dedicated make up air units for office space

• demand control ventilation (DCV) in the auditorium

Measures were evaluated independently and as part of the package, to consider both stand-alone and interactive cost-effectiveness.
