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 12,162,332.18 Kilowatt-hours 41,497.88 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 21,465 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
62,962.88 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
89,725.25 Gross square meters

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:
The baseline was adopted across STARS credits based on Agnes Scott's best historic data within recent years. This same baseline has been used across all STARS reports.

Source energy

Source-site ratio for imported electricity:
3

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.69 MMBtu per square meter 1.46 MMBtu per square meter
Baseline year 0.70 MMBtu per square meter 1.63 MMBtu per square meter

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:
10.11

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
The Center for Sustainability marked Energy Efficiency Day (Oct. 2) in 2019 through awareness in the Irvine, encouraging staff, faculty and students to challenge themselves in the month of October to do three easy energy saving activities (turning lights off when not needed, keep their thermostats at an energy-saving temperature and unplug devices that are not needed) to eventually turn these into habit. October 2 also marked the start of the People’s Drawdown Ecochallenge where we had the Agnes Scott community engage in efficiency and conservation habits across a wide variety of topics, including energy.

The Environmental Residents also create signage in the residence halls as simple sustainable habit reminders some of which were on energy conservation.

A brief description of energy use standards and controls employed by the institution:
The Office of Facilities manages building temperature standards and occupancy/vacancy controls, including adjusting campus-wide temperatures when the College is closed for winter and summer breaks.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Through funding from the College’s Green Revolving Fund, more than 80% of campus lighting has been updated to LED.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Agnes Scott has two geothermal HVAC systems on campus, meaning that 10% of the College’s square footage is cooled and heated with geothermal.

A brief description of co-generation employed by the institution:
Agnes Scott employs the Green Revolving Fund to replace energy-consuming equipment, such as the chiller and boiler in McCain library, and the re-commissioning of the Bullock Science Center.
