| Baseline period | July 1, 2015 | June 30, 2016 |
A brief description of when and why the energy consumption baseline was adopted:
FY 2015-2016 was used because this was before we started putting solar panels up and we find it useful to keep track of that change.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.08 MMBtu per square foot | 0.14 MMBtu per square foot |
| Baseline year | 0.07 MMBtu per square foot | 0.14 MMBtu per square foot |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
BHSU leads by example, showing other institutions in the area what is possible in terms of renewable energy installation by sharing their efforts through publications, presentations, etc.
A brief description of energy use standards and controls employed by the institution:
BHSU utilizes a building automation system with occupancy sensors. BHSU installed occupancy sensors in occupied spaces, both in new construction and during renovation projects.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
BHSU has completed a full replacement of outdoor lighting to LED. We have converted all of the indoor lighting to LED.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
N/A
A brief description of co-generation employed by the institution:
N/A
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
When acquiring energy-consuming products State agencies shall purchase ENERGY
STAR® designated products. An agency is not required to procure an ENERGY STAR® designated product if the head of the agency determines in writing, to the Office of Procurement Management, that no ENERGY STAR® designated product is reasonably available that meets the functional requirements of the agency; or that no ENERGY STAR® designated product is cost effective over the life of the product taking energy cost savings into account.
BHSU has contracted with UNESCO on an energy saving performance contract.
