5.1 Energy consumption per square meter
Convert site energy figures to megawatt-hours (MWh) using the STARS energy calculator or an equivalent resource.
Peer group:
Gross floor area of building space:
Electricity
Description of the on-site renewable systems:
A 24.7 kW photovoltaic array is installed on the roof of the Micron Business and Economics Building. The array consists of (76) nominal 325W panels oriented roughly east and west, tilted approximately 10 degrees up from horizontal.
This array generates 24,579.89 kwh per year, which equates to 24.57989 Mwh.
On-site renewable electricity exported:
Electricity from off-site sources:
Stationary fuels
Include all liquid, solid, and gaseous fuel products sourced during the performance year for the purpose of producing electricity and/or thermal energy, irrespective of whether they were used or not. Transportation fuels are excluded.
Propane/LPG:
Heating oil:
Coal/coke:
Bioenergy products:
Other stationary fuels:
Heating and cooling from off-site sources
Include all district heating and cooling products sourced during the performance year from a utility or municipal facility.

The University contracts with the City of Boise to use district geothermal water as a heat source for eleven campus buildings. The City administers the nation’s largest geothermal district heating system. Geothermal water supplies heat to building hydronic loops via plate and frame heat exchangers. Generally, the high-temperature resource is used directly, but one building has a “cascade” arrangement where low-temperature return water from an adjacent building supplies a water-source heat pump loop. Geothermal water is furnished as an interruptible resource so backup heat is required for each building.
How Geothermal Works
Deep below our earth’s surface runs a natural resource that the City of Boise has been utilizing for more than a century. A river of geothermally heated water flows under our city’s foothills. From heating buildings to sidewalk snowmelt and warming recreational pools, the City of Boise’s geothermal heating utility is innovative, renewable – and sustainable to the core.
