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

The baseline year is FY2010. This year was selected because it was a transition time from Western. The College created a sustainability strategic plan during this year, in doing so Western used this year as a baseline for all efforts moving forward.


Source-site ratio for imported electricity:
3

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.05 MMBtu / GSF 0.09 MMBtu / GSF
Baseline year 0.11 MMBtu / GSF 0.20 MMBtu / GSF

Percentage reduction in total source energy consumption per unit of floor area from baseline:
53.49

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

Western conducts two campus-wide shut-down audits per year. This includes visually inspecting every space on campus to insure compliance with shutting down lights, computers, monitors, closing blinds, and unplugging personal appliances. All employees who successfully shut-down their space are eligible for rewards.

Every thermostat across campus has a color label indicating cooling season and heating season temperature ranges and an email contact, should occupants have comfort concerns.


A brief description of energy use standards and controls employed by the institution:

All buildings are run using Automated Logic software to make real-time decisions on HVAC system use. In addition, Automated Logic is connected to our campus classrooms scheduling software in order to regulate HVAC systems on a classroom by classroom basis according to when they're occupied.

Cooling Season (Typically May-September)
Occupied Temperature Range: 74°F - 78°F

Heating Season (Typically October-April)
Occupied Temperature Range: 68°F - 70°F
Unoccupied: 55°F


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

Western installs all LED lights in all new and remodeled building spaces. In 2020, Western has budgeted $450,000 to spend in LED lighting upgrades.

College-wide policies include:

-Make certain that lights are turned off when leaving the classroom, restroom, mailroom, break room, and/or office. All unnecessary lighting in unoccupied areas should be off.

-All lights will be turned off when students and staff leave for the day (classrooms, restrooms, mailrooms, break rooms, hallways and offices). The only exception is emergency lighting.

-Utilize natural lighting when/where appropriate. Refrain from turning lights on unless definitely needed. (Remember that lights not only consume electricity, but also give off heat. This places an additional load on the air conditioning equipment and thereby increases the use of electricity necessary to cool the room).

-Gym lights should not be left on unless the gym is being utilized.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

The Integrated Technology Center building utilizes closed loop geothermal system and a solar wall. The parking lot adjacent to the building contains 128 geothermal wells, each 400' deep, with a capacity for 325 tons of cooling. The solar wall is used to preheat incoming air, achieving a ten-plus-degree difference. An open loop geothermal system is in place at Western's Sparta location. The Heavy Truck and Equipment building uses a passive solar wall to preheat incoming air.


A brief description of co-generation employed by the institution:

None.


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

Western Technical College is currently working on creating an Asset Management Program that will allow us to keep track of our assets and the condition they're in, replacing appliances, equipment, and systems with more efficient versions as they break.

Western is spending $450,000 in LED lighting upgrades in 2020.
