A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
1. Set a new standard for our BD+C Leed Certification- Minimum Level Gold.
2. Use renewable energy sources on the site of all new projects.
3. Retro Commissioning of Control System Schedules to remove any over-ridden schedules.
4. Begin the addition of new sub metering and energy tracking in buildings over 50K GSF to work toward meeting the requirements of WA HB1257.
5. Hired a Sustainability Coordinator who planned community outreach events and spread awareness of the direction CWU is headed.
A brief description of energy use standards and controls employed by the institution:
We have construction standards for all renovations and new buildings that include Lighting Controls, Building Automation, HVAC Automation, Occupancy Sensors, LED Lights, High Efficiency Equipment, and the Addition to alternative energy sources.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
CWU has deployed standards for Renovations and New Construction that include the use of energy efficient, dimmable LED Lighting and a sophisticated NLight lighting control system. This lighting control system utilizes audio/motion occupancy sensors in all locations, sophisticated schedules to ensure lights do not operated during unnecessary times and the addition of Daylight Harvesting Sensors near any outdoor windows.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
CWU is in the process of completing a geothermal feasibility study with an engineering consultant to look at the potential of adding geothermal to some of our existing buildings and/or new constructions. In the meantime we plan to work toward our end goal of net zero by expanding our low temp heating water loop in preparation for the addition of adding geothermal. Additionally all new buildings are being designed to operate on low temp heating water that can easily be produced by a water-side heat pump so we can add geothermal at any time. The addition of geothermal will depend on funds available from the State of Washington.
A brief description of co-generation employed by the institution:
None.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
We have multiple minor works projects associated with energy consuming equipment. Most are to reduce the energy use by energy intensive spaces. One example is digitizing Phoenix Chemical Hood Airflow Valves to ensure tightened control and proper airflow measurement of system. This project is projected to reduce energy by the Labs our Science 1 building by as much as 30%.
