A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

The UMass Physical Plant issues campus wide reminder emails to conserve energy during winter months, holiday breaks, and during peak demand times in the summer months. UMass Sustainability partners with Environmental Health & Safety and Design & Construction Management to provide energy saving stickers and signage in the Physical Science Lab fume hoods.


A brief description of energy use standards and controls employed by the institution:

Measurement and Verification (M&V) is a requirement for all new construction projects on the campus per the 2018 Green Building Guidelines. UMass Facilities Engineers use Energy STAR Portfolio and METASYS to track energy EUI and consumption trends in over 170 buildings.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

As part of the Eversource 3 Year Memorandum of Understanding MOU with UMass Amherst (2017-2020) UMass continuously performs lighting retrofits. The Physical Plant Maintenance Department also has a full time Facilities Engineer who primarily oversees lighting upgrade projects in facilities across the campus. In FY19 UMass reported to MA DOER 6 LED retrofit projects totaling 115,953 kWh annual savings.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

UMass currently has three buildings using ground source heat pump systems as the primary heating and cooling equipment. The Police Station, Research Admin, and Crotty Hall. These buildings are not on the central steam system so therefore utilizing on-site alternative energy through GSHP technology.


A brief description of co-generation employed by the institution:
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

The Energy and Facilities Engineers in Physical Plant Maintenance Department are tasked with building re-commissioning.
