Cardinal Green Buildings

Stanford operates and maintains hundreds of campus buildings. While advanced systems ensure these buildings operate efficiently, a critical tool in helping further reduce Stanford’s energy use is the collective action of building occupants. Since 2001, turning off heating systems and custodial services in buildings during holiday breaks, as well as the conservation behaviors of building occupants to support these efforts, has avoided more than $4.9 million in utility costs over the past 18 years. View a detailed breakdown of annual savings here. 

Through the Cardinal Green Buildings campaign, the Office of Sustainability and SEM Business Services (SSBS) works with partners in Facilities Energy Management (FEM) and Zone Management to develop additional opportunities for targeted energy conservation. The campaign engages and educates our campus community in energy  reduction measures that can have a significant impact on building sustainability. To kick things off, the season marks the release of the annual Building Sustainability Ratings, issued each year to provide insight into how core campus buildings perform across six sustainability categories. In addition to targeted actions around energy conservation, explore your building rating to learn about conservation opportunities.

 Building Managers

At the building level, the campaign targets turning off heating and ventilation systems, as well as custodial services, to conserve energy during closures.  FEM and SSBS work with specific buildings to facilitate a shutdown during Thanksgiving and Winter Closures, and with some buildings during shorter long-weekend holiday periods.  As a building manager, you qualify for a $250 incentive once you earn 100 points through the My Cardinal Green online platform.
