None
A brief description of when and why the building energy consumption baseline was adopted:
The baseline year was chosen as it was after any major renovations and building construction. The baseline year is recent enough to capture reliable data from the past and use that to see how much progress we have made with sustainability efforts.
None
A brief description of any building temperature standards employed by the institution:
Most areas are heated to 70 degrees F and cooled to 72 degrees F.
None
A brief description of any light emitting diode (LED) lighting employed by the institution:
The campus is trying to convert more and more spaces to LED. Many large spaces and spaces with daily usage have already been converted to LED lighting. About 1/3 of street lights have been converted to LED.
None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
The campus has used occupancy sensors in some general areas, hallways, bathrooms, and other controlled spaces that would allow for a sensor to accurately determine if a space is occupied.
None
A brief description of any passive solar heating employed by the institution:
n/a
None
A brief description of any ground-source heat pumps employed by the institution:
n/a
None
A brief description of any cogeneration technologies employed by the institution:
n/a
None
A brief description of any building recommissioning or retrofit program employed by the institution:
Any building remodeling projects would be looked at as a way to evaluate the current energy consumption items and challenge if there are better alternatives available.
None
A brief description of any energy metering and management systems employed by the institution:
Most buildings have electrical meters or other meters installed so we can monitor those buildings for energy consumption. This is used for determining problems and recommending areas to target for energy efficiency projects. The data is also used for providing feedback from energy efficiency projects in the past.
None
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
Each and every piece of equipment is constantly being evaluated for possible efficiency upgrades. Buildings are also put on a scheduled rotation for upgrades and scheduled down time to replace equipment that is ageing or that newer higher efficiency options exist. Most appliances are put on a scheduled rotation that follows the buildings being evaluated.
None
A brief description of any energy-efficient landscape design initiatives employed by the institution:
n/a
None
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
Vending machines are supplied by a 3rd party.
None
A brief description of other energy conservation and efficiency initiatives employed by the institution:
Through maintenance and replacement we challenge what the current need is for all equipment and evaluate what exists with newer technology or products that can be implemented for efficiency gains. The college uses Physical Plant and internal organizations like the Calvin Energy Recovery Fund to orchestrate and accomplish those goals.
