The Francis Cabot Lowell Mill I & II

Solutions

The property applied to and was accepted as a Low-Income Energy Affordability Network (LEAN) project. The LEAN program is designed to help low- to moderate-income developments improve energy savings by offering equipment, lamps, and fixtures free of charge to qualifying properties.

Action Energy Services, an energy efficiency contracting program that partners with LEAN, designed a high-efficiency gas fired boiler and indirect water heater system for the property which features multiple boilers with thermal efficiency rating of 92% or greater. In addition to the boiler upgrades the LEAN program assisted in the conversion of all the common area lighting from recently converted T8 fluorescents to LED lamps.

The project started at the end of the heating season in June 2017 so as not to disrupt the comfort of tenants. The heating equipment was removed from the boiler rooms and the hot water was swapped from the old system to the new one in a single day, thus limiting disruption of hot water.
