OP-5: Building Energy Consumption

First year we have data for.

The Campus Sustainability Office does a New Employee presentation for all new PSU staff and faculty. This presentation goes over the University goals and what staff/faculty can do to reduce their own energy consumption. The Campus Sustainability Office and/or Student Sustainablity Center does tabling at orientations and other events throughout the year on campus, providing students, staff, and faculty with information about how to help us reach our sustainability goals The Campus Sustainability Office provides training for all Resident Advisors so they are have information and tips to share with their residents on how to conserve engery while living in residential facilities. The Student Sustainability Center's EcoReps program, provides peer-to-peer educational programs for residents living in housing The PSU Climate Champions Program is designed to promote and recognize resource conservation and stewardship within PSU departments, as well as to support the goals of our Climate Action Plan. The Campus Sustainability Office presents to classes and at departmental meetings across campus providing education and resources to students, staff, and faculty.

Energy Conservation Guidelines (Heating and Ventilation): -Conditioned spaces will be heated to a temperature range of 67-70 in the winter and cooled, where applicable, to a temperature range of 72-76. Plan for the season and dress appropriately. -Personal or University owned space heaters will not be allowed, unless approval from FPM has been granted for cases where spaces cannot otherwise be heated to the appropriate range. Once approval has been granted, space heaters must comply with fire code, be turned off when a space is not being occupied and be selected with energy efficiency and safety as top priorities. FPM will then work to identify a long range solution to heating the space to an appropriate level. -Building ventilation will be based on actual use of the space, as determined by Academic Schedules, Posted Building Occupancy, and Special Events. -Windows in conditioned spaces are to remain closed when building conditioning systems are operating. -All supply and return air vents in offices, classrooms, and laboratories must be unobstructed at all times. -Utility Manager and Facilities staff will work with events scheduling team to consolidate activities into energy efficient buildings on campus

Energy Conservation Guidelines (Lighting): -All spaces will be lit to an appropriate lighting level for the tasks being performed. Extra effort will be made to ensure that unoccupied spaces are left at minimum acceptable levels. -Building occupants are encouraged to take advantage of natural light, whenever possible. -New construction and renovation will incorporate daylight sensing technology, allowing overhead fixtures to dim when outside lighting is sufficient. -Utilize energy efficient bulbs in task lighting (i.e. compact fluorescent or LED) Parking Garages have been converted to LED lighting, Lighting Retrofit Project for converting Hoffman Hall to LED lighting was approved by the Green Revolving Fund in FY 14, as was an exterior LED lighting and daylight control project for Science Building 1. All street lighting along the park blocks running through campus are also LED. PSU is currently working on several other lighting upgrades that will include LEDs. Last year (2017/2018) the Student Building Fee Committee approved funding to upgrades several classrooms across campus to LEDs. This year PSU is scoping a project to get the remaining general purpose classroom converted to LEDs using our Green Revolving Fund.

-EB Heating and Cooling provided by heat pumps using geothermal wells. -CH chillers use well water for condenser water -A portion of our newly renovated Karl Miller Center includes passive design.

Last year a Heat Recovery Chiller was placed in our computer server room in Fourth Avenue Building. Last year the entire Fourth Avenue Building was heating using this method and the gas boiler was never turned on. PSU is also looking into adding heat recovery chillers to our district energy loop. We hope to fund this work through our Green Revolving Fund.

The Green Revolving Fund (GRF) is a revolving fund that provides funding for efficiency projects across campus that support energy reduction and climate action goals. The initial fund was set up in 2013 with $500,000 from the State of Oregon for capital improvements and since has added additional funding through savings from the University’s utility budget, energy incentive rebates from the Energy Trust of Oregon, and the University’s voluntary travel offset program for a total fund of over $1.5 million. Since inception, the GRF has supported over 15 projects and resulted in an anticipated energy savings of over $250,000 annually. Example Projects: -Millar Library and University Center Building retrocommissioning -Science Research & Teaching Center stand alone chiller for energy intensive labs -Science Research & Teaching Center installation of Zenn Valve to reduce water usage -Millar Library LED upgrades -Science Building One installiton of heat revoery chiller and electric hot water heater to reduce laod on campus loop boilers in the summer months Other projects not included in the GRF: Fourth Avenue Chiller replacement and heat-recovery chiller, West Heating Plant new boilers, SRTC Heat Recovery for summer and winter operations, MCB natural gas boiler replaced electric resistance heat. CH domestic hot water now via Heat Recovery from Telecom room cooling system
