Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 92,918 MMBtu 93,691 MMBtu
Electricity from on-site renewables 3,286 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) 37,067 MMBtu 208,895 MMBtu
Total 133,271 MMBtu 302,586 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2014 June 30, 2015
Baseline Year July 1, 2005 June 30, 2006

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):

2006 is the year the college established its Sustainable Use of Resources Policy,

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 2,503,171 Gross Square Feet 1,938,925 Gross Square Feet

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.05 MMBtu / GSF 0.16 MMBtu / GSF
Source energy 0.13 MMBtu / GSF 0.26 MMBtu / GSF

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 3,611 Degree-Days (°F)
Cooling degree days 650 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 0 Square Feet
Healthcare space 0 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
2,503,171 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
12.49 Btu / GSF / Degree-Day (°F)

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):

The Power Shift initiative promotes energy conservation practices and engages employees to participate and track their personal energy consumption and participate in annual energy reduction challenges through NWEI Eco Challenge.

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

All buildings at PCC are operated with DDC temperature controls and all buildings are operated on schedules based on occupancy. Our DDC system is accessible through a graphic front end that allows us to schedule the operation of major equipment based on occupancy and optimal start programs so that the space temperatures are achieved for occupancy using the least amount of energy.

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

LEDs are used to replace older lighting as we work to phase these out across the district. Recessed can lighting manufactured by HALO make up the bulk of the inside lighting, at 14 watts per fixture. Parking lot lighting is also being upgraded to LEDs made by BETA.

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

Passive solar features such as vertical sun shades that protect against late afternoon sun and horizontal shades that protect against early afternoon sun help keep new LEED certified buildings cool. Overhangs protect against solar heat gain while carefully placed windows let in natural light, saving electricity. The Newberg Center, a Net Zero Building uses natural ventilation and fans to efficiently cool the building. When open, louvers on the exterior wall of the building draw in fresh air from outside and turbines spin to help pull hot air out of the building. Exposed concrete in the building acts as thermal mass, helping maintain even building temperatures all year long.

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

Cogeneration fuel cells powered by natural gas are used at the Sylvania campus. These fuel cells power the gymnasium and heat the indoor pool.

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):

Upgrades of appliances dictates choosing Energy Star options when applicable, and our replacement schedule factors in when the energy use of older, less efficient models warrants replacement.
