We strive to give our patrons a wonderful experience, which also includes compelling pieces of art, but an exceptional facility too. Not only we will be using less energy, which is great for the environment, but these improvements will vastly improve the comfort for our patrons and employees. This project was a major undertaking that will pay dividends for years to come.
Main project details
The Elm Street and Merriam Parkway buildings received extensive upgrades that include the installation of a building management HVAC software system to optimize the new 14 high efficiency heat pump installed. In addition, a heat pump water heater and two high efficiency natural gas boilers were added to complement the heat pumps.
According to Unitil, the heat pumps function as the first stage primary heating with oil and gas boilers coming online as outdoor temperatures drop. “Operating the buildings with multiple fuels allows for potential economic optimization as well, switching from heat pumps to legacy fuels when it is cost effective to do so,” added Unitil’s Senior Energy Efficiency Program Coordinator Joe Van Gombos.
While its electric usage will increase, the new heating and cooling systems reduces natural gas usage by 288.6 MMBtu and oil by 97.87 MMBtu annually. The project received a $93,925 energy efficiency rebate from Unitil for achieving a carbon emissions reduction of approximately 20 metric tons, which over the lifetime of the equipment is equivalent to the emissions 43 homes produce annually.
