None
A brief description of any building temperature standards employed by the institution:
UW employs building temperature standards as follows:
- For capital projects, the Facilities Services Design Guide (FSDG) provides building temperature guidelines for new construction, renovations and remodel projects. FSDG states design space temperatures in capital projects shall be as established by City and State Energy Codes. Previous Seattle Energy Codes required interior design temperatures to be a maximum of 70F for heating and a minimum of 78F for cooling. FSDG states general use buildings with mechanical cooling will be cooled to 78F unless further restricted by City or State Energy Codes. FSDG requires listing all space heating temperature setpoints that differ from 68F. FSDG states unoccupied spaces shall be heated to minimum 40F for freeze protection. FSDG states hydronic heating system shall be on a reset schedule, normally resetting heating hot water down from 180F to 140F when outside air temperature rises from 20F to 70F. FSDG states reheat coil heating hot water temperature is normally set at 140F. FSDG states night setback temperatures shall not drop below 55F. FSDG states mechanical and electrical rooms shall be ventilated so space temperature does not exceed 90F.
- Operationally, building temperatures are adjusted by each building's own control system. UW's building control systems include direct digital control (DDC) systems by several manufacturers, pneumatic control systems, or standalone controls. DDC systems are remotely monitored from a central server location.
None
A brief description of any light emitting diode (LED) lighting employed by the institution:
UW employs LED lighting fixtures in these Seattle Campus Buildings
1: Paccar Hall
2. Dempsey
3. Stevens Court (Community Center Conference Room
4: HUB (Building interior and surrounding pathway lighting)
5. Mercer Hall (corridors at apartment entrances & exterior pathways
6, Plant Services Bldg. (Facilities Services Training Center)
7. Alder District Market
8. Poplar Apartments
None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
UW employs occupancy sensors to control lighting in several newer buildings.
None
A brief description of any passive solar heating employed by the institution:
UW employs passive solar heating as follows:
- Many campus buildings constructed of brick or concrete have large thermal masses that store thermal energy
- Several buildings have south-facing glass with light shelves that allow direct solar gain in winter
- Molecular Engineering's ceilings and wall cavities are filled with phase change material that increase thermal mass and store thermal energy. Solar chimneys with turbine ventilators naturally ventilate office spaces.
None
A brief description of any ground-source heat pumps employed by the institution:
None
None
A brief description of any cogeneration technologies employed by the institution:
UW employs cogeneration by combusting natural gas to produce steam, which produces electricity in a steam turbine generator prior to distribution of steam to the campus for heating.
None
A brief description of any building recommissioning or retrofit program employed by the institution:
UW employs building recommissioning or retrofits as follows:
- energy engineers auditing buildings recommend system and controls modifications
- HVAC airflow rebalancing has been performed in several buildings, with an ongoing project to rebalance other buildings
None
A brief description of any energy metering and management systems employed by the institution:
UW employs energy metering and management as follows:
- electricity meters recently installed in all central campus buildings as part of a regional smart grid project have meter data remotely collected at a central database.
- chilled water meters recently installed in all buildings have meter data remotely collected at a central database.
- steam condensate meters recently installed in 21 research buildings have meter data remotely collected at a central database. Steam condensate meters in buildings housing self-sustaining departments are monitored monthly.
None
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
UW's program to replace energy-consuming appliances, equipment and systems is as follows:
- Printopia strives to standardize department copiers and printers, with a goal of reducing copier and printer energy use by 50%
- UWIT encourages
None
A brief description of any energy-efficient landscape design initiatives employed by the institution:
---
None
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
UW employs motion sensors on nearly all vending machines. All vending machines are Energy Star rated.
None
A brief description of other energy conservation and efficiency initiatives employed by the institution:
UW employs other energy conservation and efficiency initiatives as follows:
- UW Tower Data Center is one of twenty-seven data centers in the country to have earned a 2013 ENERGY STAR certification.
- UWIT promotes green computing by encouraging departments to purchase computers and electronics that are ENERGY STAR and EPEAT compliant, allowing computers to sleep when not being used, using flat monitors in lieu of conventional tube monitors, powering down equipment when not in use, and considering virtual services.
