Chestnut Place apartment community in Ashland, MA is a garden-style multi-family apartment complex comprised of 6 buildings with 207 units. The community is a mix of 1- and 2-bedroom units arranged in 2 story buildings. Built in 1971, this property features many original electric and gas systems.

Through the RENU process, Chestnut Place is expected to avoid 324 tons of CO2 each year. Planned RENU improvements to the property’s building envelope include LED lighting and roof insulation upgrades. The RENU scope also includes full retrofit of the HVAC and central hot water system with advanced cold climate heat pumps and CO2 heat pump water heaters. Both systems will drastically reduce the property’s energy demand and improve energy resiliency.

Recognizing the impact solar PV could have at Chestnut Place, RENU plans to install approximately 195 kW (DC) of rooftop solar PV and an additional 330 kW (DC) of parking lot canopy solar PV. This would maximize the solar production, as well as drastically increase the CO2 savings at Chestnut Place.

Following the construction of the property’s new energy infrastructure, RENU will manage, maintain, and monitor these systems to maximize energy efficiency and environmental health through our integrated energy management and monitoring system.
