Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):
kWh MMBtu
Imported electricity 39,385,686.28 Kilowatt-hours 134,383.96 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) 0 Kilowatt-hours 0 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):
MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy 1,232,480.60 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
1,366,864.56 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
2,186,959 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):
Start date End date
Baseline period July 1, 2004 June 30, 2005

A brief description of when and why the energy consumption baseline was adopted:
A baseline year of FY2005 was selected as this is the first year that comprehensive data is available for energy reporting and aligned with previous reporting.

Source energy

Source-site ratio for imported electricity:
3

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.46 MMBtu per square foot 0.47 MMBtu per square foot
Baseline year 0.63 MMBtu per square foot 0.75 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:
36.60

Optional Fields 

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:
---

A brief description of energy use standards and controls employed by the institution:
Multiple buildings on campus have "occupied" temperature set-points and "unoccupied" temperature set-points. The building's automation systems alter the temperature and ventilation within the building prior to the start of the workday as well as at the conclusion of the work day. Ability for occupant to increase or decrease the temperature in their area is limited by the building management system.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED Lighting is employed in the parking garages, LEED buildings, the Lazare Research Building, Power Plant and all newly renovated spaces.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
UMass Chan is undergoing construction for its newest building, which features 75 geothermal boreholes under the campus green. The building is expected to go online in Spring of 2024.

A brief description of co-generation employed by the institution:
The 17.5MW combined heat and power plant provides 100% of the steam and chilled water needs to the campus and about 90% of the electricity needs.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
UMass Chan has retro-commissioned several buildings including the Albert Sherman Center, Ambulatory Care Center and the Lazare Research Building. Additionally, UMass Chan is utilizing IDS, a fault diagnostic software, to identify faults in the HVAC with could impact energy consumption. UMass Chan is also currently assessing its research freezer inventory with the assistance of an intern, and is undergoing a cost-benefit analysis to replace aging freezers with more energy efficient models.

Data source(s) and notes about the submission:
Campus dining locations are located in either laboratory or healthcare buildings, to avoid double counting these were not additionally included in "other energy intensive space"

The difference between the performance year and the baseline year amounts under "Imported electricity" may be due to increased electrical generation on-campus, increased behavioral and operational energy efficiency measures. In addition, variations in building occupancy due to COVID may have impacted the amount of electricity needed to support our structures.

In 2012 as part of the Sherman Center they completed a plant explanation project and put in the HRSG generator with increased our self-generation capacity and reduced purchased electricity. While imported electricity decreased, stationary fuels used on-site to generate electricity and/or thermal energy increased which may be due to variations in building occupancy and building construction on-site.
