A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
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.
As part of our Strategic Energy Management Program (check in with Farid)
A brief description of energy use standards and controls employed by the institution:
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:
We formerly had cogeneration fuel cells powered by natural gas are used at the Sylvania campus, but these are no longer in use at the indoor pool.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
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.
