A brief description of when and why the energy consumption baseline was adopted:
The baseline year of 2011 was chosen since during this year Gustavus officially joined the American College and University Presidents’ Climate Commitment. This year also marked when the “Energy Use and Greenhouse Gas Emissions Reduction Plan” created by the director of the Johnson Center for Environmental Innovation was accepted by the Board of Trustees.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.10 MMBtu per square foot | 0.15 MMBtu per square foot |
| Baseline year | 0.12 MMBtu per square foot | 0.19 MMBtu per square foot |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Gustavus has had several initiatives over the years to educate and shift individual practices regarding energy efficiently. This includes a building energy competition (Energy wars), focusing on energy efficiency education in several first term seminar courses, turning the lights off in the cafeteria during the sustainability lunch for first years during orientation, and placing reminder stickers to turn off lights in most campus buildings including residence halls.
A brief description of energy use standards and controls employed by the institution:
Several campus buildings are LEED certified and therefore follow standards and controls outlined in their accreditation. All campus buildings are operated with energy efficiency in mind, including set temperature standards, and many buildings have occupancy and vacancy sensors for temperature controls and lights.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Over the past several years, Facilities has instituted a campus-wide LED lighting upgrade in most buildings, which includes redesigning fixtures and replacing bulbs and ballasts with LEDs (and properly recycling old bulbs and ballasts), which has already saved energy and money.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Many buildings on campus are designed to utilize passive solar heating and daylighting via window placement, including in Nobel, Beck, and Anderson. There is also a small experimental geothermal AC system connected to Olin (numbers are unavailable and very small, so they’ve been excluded from the report).
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:
Facilities has made a dedicated effort over the past several years to replace inefficient washers and dryers in residential halls with energy efficient and HE appliances, and continues to do so.
