A brief description of when and why the building energy consumption baseline was adopted:
The baseline is that same as from our last STARS report.
A brief description of any building temperature standards employed by the institution:
The campus heating and cooling set points are controlled by an Energy Management System operating with heating and cooling set points. During hours when the educational and administrative buildings are closed, building temperatures are set back to 65 degrees for the heating months.
• During normal operating hours, the buildings is set between 68 and 72 degrees.
• Building vestibules and foyers is unheated, unless needed for mechanical piping.
• Residence Halls are set at 72 degrees during the day and set back to 68 degrees during early morning hours.
A brief description of any light emitting diode (LED) lighting employed by the institution:
As part of the recent Energy Performance Upgrade, most lighting on campus is now energy efficient LED lighting.
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Earlham has motion lighting senors in 16 major campus buildings and 20 campus housing restrooms. A photocell system operates 55 parking lot lights, sidewalk lighting, and three dorm stairwells. These number have recently increased with the recent Energy Performance Upgrade project.
A brief description of any passive solar heating employed by the institution:
A brief description of any ground-source heat pumps employed by the institution:
A brief description of any cogeneration technologies employed by the institution:
A brief description of any building recommissioning or retrofit program employed by the institution:
A brief description of any energy metering and management systems employed by the institution:
• The campus heating and cooling set points are controlled by an Energy Management System operating with heating and cooling set points. During hours when the Educational and Administrative buildings are closed, building temperatures will be set back to 65 degrees for the heating months.
• During normal operating hours, the buildings will be set between 68 and 70 degrees.
• Building vestibules and foyers will be unheated, unless needed for mechanical piping.

A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
There is no formal policy for replacing appliances with energy efficient alternatives, however that is typically done.
A brief description of any energy-efficient landscape design initiatives employed by the institution:
The College has a large rain garden off the Athletic and Wellness Center. It also uses native plants where possible.
