A brief description of when and why the building energy consumption baseline was adopted:

In 2007 Warren Wilson College committed to reducing our green house gas emissions by 80% by 2020. An inventory of energy use has been taken every year since that date.

A brief description of any building temperature standards employed by the institution:

Four of the buildings on campus have timer regulated temperature systems. These buildings are programmed as 'occupied' between the hours of 7am and 5pm. The rest of the time, the heating/cooling system only turns on above 90 degrees F or below 55 degrees F.

A brief description of any light emitting diode (LED) lighting employed by the institution:

In 2014 year the college replaced our campus street lighting, and our Cannon Lecture Hall with LEDs

A brief description of any occupancy and/or vacancy sensors employed by the institution:

Both passive infrared and ultrasonic motion sensors are used in several buildings on campus. Light sensors are present in select hallways and the library where enough light during the day allows for the lights to be turned off.

A brief description of any passive solar heating employed by the institution:

The Eco-dorm uses passive solar water heating. A hallway in the Witherspoon science building uses passive solar to help heat the building

A brief description of any ground-source heat pumps employed by the institution:

Jensen, a three story humanities building, uses ground source heat pumps to supplement heating and cooling energy needs.

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:

Any retrofit project includes maximizing energy efficiency.

A brief description of any energy metering and management systems employed by the institution:

Institutional Effectiveness tracks campus-wide energy consumption monthly via billing. It is not a fancy process or technologically sophisticated tool, but it works and is already available. We have electricity meters on 100% of campus buildings and natural gas meters on 95%. Abnormalities in the data are reported to Facilities Director.

A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:

Our policy is to replace equipment with Energy Star certified or better.

A brief description of any energy-efficient landscape design initiatives employed by the institution:

Warren Wilson College aims to minimize mowed areas to reduce energy intensive lawn mowing. We grow wild grasses to cover much of our campus, and periodically burn them down. The campus has only 8 acres of mowed areas, including 5 acres of soccer fields.

A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:

Sensors were installed in vending machines in dormitories. Those sensors did not work effectively so they were removed.

A brief description of other energy conservation and efficiency initiatives employed by the institution:

EPA Green light compliant
