"---" indicates that no data was submitted for this field

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 28,741.14 MMBtu 28,202 MMBtu
Electricity from on-site renewables 7.50 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 41,844 MMBtu 43,100 MMBtu
Energy from all other sources (excluding transportation fuels) 0 MMBtu 0 MMBtu
Total 70,592.64 MMBtu 71,302 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2015 June 30, 2012
Baseline Year July 1, 2016 June 30, 2007

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

FY 2007 was chosen because it was the year BHSU performed its first greenhouse gas emission report.


Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 816,630 Gross Square Feet 723,718 Gross Square Feet

Source-site ratio for grid-purchased electricity:

Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:
---

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
---

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

BHSU utilizes a building automation system with occupancy sensors.


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

We are currently undergoing a complete replacement of outdoor lighting to LED. We have converted much of the indoor and outdoor lighting to LED.


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

A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
---

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):

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 completed two performance contracts for energy efficient building retrofits.
