Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 249,523.50 MMBtu | 293,280 MMBtu |
| Electricity from on-site renewables | 10,030.42 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 896,826.70 MMBtu | 573,500 MMBtu |
| Total | 1,156,380.62 MMBtu | 866,780 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2018 | June 30, 2019 |
| Baseline Year | July 1, 2004 | June 30, 2005 |
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):
2005 is the most recent year in which we have comprehensive energy data.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 946,814.79 Gross square meters | 635,392.32 Gross square meters |
Source-site ratio for grid-purchased electricity:
3.14
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 1.22 MMBtu per square meter | 1.36 MMBtu per square meter |
| Source energy | 1.79 MMBtu per square meter | 2.35 MMBtu per square meter |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
24.09

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):
Various programs target behavior change on a small scale. An updated list is covered in the Energy category of our blog: http://blogs.oregonstate.edu/ecologue/?cat=356
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
Most OSU buildings have temperatures regulated by centralized building automation systems (BAS). The BASs adjust temperature depending on hours of occupancy for the specific building and, in some spaces, based on actual occupancy using interior sensors.
Buildings not on BAS systems also typically have some sort of timing for HVAC control.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lamps are currently being used in hundreds of locations on campus, usually replacing incandescent lamps, and most recently, replacing some fluorescent as well. New construction has implemented LED lighting technology for interior and exterior application.
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):
At the LEED Platinum Energy Center, electricity is generated in a gas turbine (fueled by natural gas), which then creates high quality waste heat. This waste heat is used to make steam for campus. The Energy Center provides about 40% of the electricity for campus. https://fa.oregonstate.edu/sustainability/operations/green-building/completed-construction
