Building Sustainability Ratings
Stanford has developed a rigorous internal building sustainability rating system to identify high performers and target buildings for improvement. The system evaluates a building’s sustainability performance across six categories, which are measured and analyzed on annual basis. This is intended to provide greater visibility into building performance, beyond simple meter data, to motivate action and inform where additional resources need to be invested.
While specific opportunities may vary by building, the actions of building occupants are critical to its overall performance. You can earn points toward your reward in My Cardinal Green for taking these measurable steps to help improve your building rating:
- Install a smart power strip for your computer equipment
- Follow the Sustainable Purchasing Guidelines
- Join the Commute Club
- Use the Cardinal Green Office Program Resource Library
- Take a Sustainable Office Spaces Training
More than 135 of Stanford's large utility consuming and core campus buildings are evaluated through the sustainability rating program. Average scores in each category range from six to 83%, with overall scores averaging 70%. Explore the map and click on your building to learn more.
If you are interested to learn more about your building's sustainability rating, the Office of Sustainability and SEM Business Services can provide a comprehensive report for your building. You can view a sample, and contact Moira Hafer to request a full report. A performance summary is included below.
Performance Categories and Targets
Performance targets are informed by national industry benchmarking programs, such as Leadership in Energy and Environmental Design and the Association for the Advancement of Sustainability in Higher Education's Sustainability Tracking Assessment and Rating System. The overall building rating is based on a weighted average of the individual performance categories.
|Performance Category||Weighting Allocation||Performance Metric||Target||Data Sources|
|Energy||40%||Energy use/square foot/ year||Building specific (based on technical potential of economically feasible efficiency measures in building)||Electricity, chilled water, and hot water building meters, and non-Stanford utility data|
|Water||15%||Annual potable water consumption and % low-flow water fixtures||Building specific (based on feasible percentage of low-flow water fixtures)||Domestic water building meters|
|Waste||10%||% waste diverted from landfill||75%||Volume of waste recorded by hauling staff|
|Transportation||20%||% employees that utilize sustainable commutes||70%||Annual employee commute survey|
|Purchasing||5%||% spend that meets the Responsible Purchasing Guidelines||50%||Office supply purchases, provided by Procurement|
|Occupant Engagement||10%||% of building occupants that participate in My Cardinal Green||90%||My Cardinal Green|
