Documentation to support the performance year energy consumption figures reported above:
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 BAS in most buildings on campus to control comfort and energy consumption.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
UMass continuously performs lighting retrofits and is currently using the GRITS platform to track all EE projects.

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, International Programs, and Crotty Hall. These buildings are not on the central steam system so therefore utilizing on-site alternative energy through GSHP technology. UMass Carbon Zero Plan is focused on moving to a low temperature hot water distribution system for the campus paired with large scale geo-exchange and heat trading systems.

Data source(s) and notes about the submission:
The attached documentation to support the performance year energy consumption figures reported above include all imported electricity and on-site fuel consumption. It does not include the data used to report the electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems). The 5,965,015.0 kwh of electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems), comes from our on-site solar generation from solar parking canopies in Lot 25, Lot 44, Lot 49, Robsham Visitor Center Lot, rooftop systems on Computer Science, Police Station, Rec Center, Champion Center, and Fine Arts Center, and the South Deerfield Farm agriculture-solar array. Lot 21-22 solar canopy did not come online until FY23.
