From the ruins of a former hydroelectric plant to a shining example of excellent commercial building design, the property at Tremont Yard has certainly come along way over the years. Today, the building is the new headquarters of the Jeanne d’Arc Credit Union of Lowell.

Avid Engineers designed both the base building infrastructure and tenant fit out efforts, which included the use of large-scale, water-source heat pumps, 98% efficient condensing boilers and cooling towers. All premium efficiency motors were fitted with variable frequency drives, programmed to modulate motor frequency in response to building needs. The use terminal boxes enabled an enhancement in the number of independently control heating and cooling zones. Air handling equipment was fitted with enthalpy-based economizers, and carbon dioxide sensors. Other sustainable design measures included design elements coordinated with National Grid’s energy efficiency measures and incentives, resultant Lighting Power Density (LPD) values less than those prescribed by applicable 780 CMR Chapter-13 (MA Energy Code).
