Stanford Redwood City

A brief description of the innovative policy, practice, program, or outcome that outlines how credit criteria are met and any positive measurable outcomes associated with the innovation:

Stanford Redwood City is the first significant expansion for Stanford outside its original campus. The Redwood City campus reflects Stanford’s spirit, mission and culture, while complementing Redwood City's renaissance. The Stanford Redwood City campus is located across from the Stanford Medicine Outpatient Center off Highway 101. The 35-acre site is five miles from the main campus. The campus will be developed in phases over time based on the ongoing needs of the university. The first phase will accommodate nearly 3,000 staff members, who are relocating to the new campus beginning in early 2019. In addition to aligning with all Stanford sustainability targets, the Redwood City campus will be positioned as a test-bed for sustainability learning and innovation through the piloting of new initiatives and programs.

Sustainability has been included in all aspects of design, construction, and operations of the new campus. Sustainable design features include daylight harvesting, mechanical shades for passive cooling, and a sophisticated controls system with zone-level temperature monitoring and overrides. These design features, coupled with an open floor plan and central printing, will allow a significant reduction in electronic devices like personal printers and space heaters at the new campus.

Additionally, the new campus will feature a waste system that differs from the system currently used on campus. The waste system will feature single stream recycling, compost in all kitchenette areas, paper towel composting in the restrooms and fitness center, and centralized waste stations (rather than desk-side bins), which studies have shown to increase diversion rates and decrease custodial and cleaning supply costs. The cafe at the new campus also features aspects of sustainability like reusable serviceware, innovative sustainable food purchasing initiatives, and donation of leftover food each day.

A major accomplishment at the new Redwood City campus design is a mimicking of the university's heat recovery system through Stanford Energy System Innovations. The energy system boasts the signature heat recovery technology while introducing critical adaptations to adjust to the differing load types of the new campus.

Initially, developers looked at a range of options to evaluate the most environmentally and economically efficient option for an energy system in Redwood City, namely a distributed system with localized equipment in each building versus the central plant model that utilizes thermal storage and heat recovery. The analysis looked at initial capital cost, water consumption, energy consumption, carbon emissions, and operations and maintenance costs, and ultimately revealed that the central model yielded greater overall long-term cost benefits, as well as significant reductions in energy and water use.

The new plant will include similar features as the facility on campus, including:

-One 600-ton Heat Recovery Chiller,
-A 1 million-gallon capacity chilled water thermal energy storage tank,
-Three 8,000 gallon capacity hot water thermal energy storage tanks,
-and backup chillers and hot water generators.

The new system is a 1/10 scale of the campus Central Energy Facility (CEF) and incorporates all of the same concepts of heat recovery and thermal energy storage, demonstrating the scalability of the main campus model. It is projected to provide 100% of the heating demand for the new campus through recovered waste heat, as well as save approximately $60 million in operating costs over 30 years compared to a traditional local building heating and cooling system.
