Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 159,598 MMBtu | 387,098 MMBtu |
| Electricity from on-site renewables | 9,259 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 1,917,548 MMBtu | 1,408,883 MMBtu |
| Total | 2,086,405 MMBtu | 1,795,981 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2016 | June 30, 2017 |
| Baseline Year | July 1, 2003 | June 30, 2004 |
A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
Consistent with OP-1 and the MA DOER Leading by Example EO484 baseline year, baseline year is FY2004.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 12,970,149 Gross Square Feet | 10,022,960 Gross Square Feet |
Source-site ratio for grid-purchased electricity:
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.16 MMBtu / GSF | 0.18 MMBtu / GSF |
| Source energy | 0.19 MMBtu / GSF | 0.26 MMBtu / GSF |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
Degree days, performance year (base 65 °F / 18 °C):
| Degree days (see help icon above) | |
| Heating degree days | 7,084 Degree-Days (°F) |
| Cooling degree days | 534 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 1,360,234 Square Feet |
| Healthcare space | 68,362 Square Feet |
| Other energy intensive space |
EUI-adjusted floor area, performance year:
Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
Documentation (e.g. spreadsheet or utility records) 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 (e.g. outreach and education efforts):
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.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
As part of the Eversource MOU (https://www.umass.edu/sustainability/climate-change-energy/energy-efficiency) 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.
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, e.g. combined heat and power (CHP):
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
The Energy and Facilities Engineers in Physical Plant Maintenance Department are tasked with building re-commissioning.
