Energy Initiatives

Stanford’s suite of energy-saving programs targets large-scale building retrofits; small-scale retrofits; heating, ventilation and air-conditioning (HVAC) controls; user habits; and new construction. In addition, the university is demonstrating solar technologies at several sites on campus.

Whole Building Energy Retrofits Program (WBERP)

The university has allocated $30 million for major capital improvements to the most energy-intensive buildings on campus. The first overhaul, of the Stauffer Chemistry Building, was finished in June 2007 and resulted in a 35 percent drop in electricity use, a 43 percent cut in steam use and 62 percent fall in chilled water use. It also cut energy costs by 46 percent in the first 12 months.

As of August 2014, the university had completed 14 WBERP projects, which are saving annually 9.5 million kWh, 5 million ton-hrs of chilled water, and 71 million pounds of steam, representing over 14,000 metric tons of greenhouse gas emissions and savings nearly $4 million per year. An additional 12 projects are in the pipeline, which are projected to save another $2.3 million per year.

Systems retrofits to the most energy-intensive buildings on campus are expected to save $4.2 million a year and cut energy use by 28 percent.

Energy Retrofit Program (ERP Rebates)

ERP Custom Projects

The Energy Retrofit Program (ERP) recently celebrated its 20 year anniversary. Since 1993, over 500 ERP projects have been completed, for cumulative annual energy savings of OVER 37 million kWh per year, or about 17 percent of 2012 electricity consumption. While the WBERP program focuses on the large central HVAC systems on campus, the ERP program promotes efficiency through building-level technology upgrades, such as premium efficiency T8 lamps and electronic ballasts, LED lighting, variable-speed drives for motors, high efficiency air compressors, high-efficiency lab freezers, and spectrally selective window film. Any campus department that is a customer of Stanford Utilities can apply for ERP rebates for projects that save electricity or thermal energy. For more information, contact Leslie Kramer.

ERP Express: Laboratory Equipment

Sustainability and Energy Management (SEM) offers financial incentives to labs that put DNA and RNA samples into ambient (room temperature) storage and/or replace old ultra-low temperature freezers. The FY15 program makes it easier for researchers to try new biological sample storage technologies and earn rebates up to $4,000. Funding is available on a first-come, first-served basis. Visit the School of Medicine (SOM) sustainability page to learn more about sustainable alternatives to frozen sample storage. Researchers on campus can earn cash back through ERP Express for Laboratory Equipment.

High Efficiency Transformers

Low-voltage transformers are used to convert the power delivered at the building entrance to the power supplied at the electrical outlets. Transformers lose power in the conversion process. Increasing the efficiency of this conversion can have a substantial impact on total building electrical consumption because transformers operate continuously whether outlets are used or not. Furthermore, because transformers emit wasted electricity as heat, inefficient transformers place a higher burden on a building’s cooling system. Stanford entered a partnership with a vendor that will lead to extensive use of higher efficiency E-Saver-3 transformers for new construction and building renovations. The transformers meet the Department of Energy’s CSL-3 standard, which offers the optimal life-cycle balance between improved efficiency and additional cost. If only 75 standard low-voltage transformers are upgraded to the CSL-3 standard, the electrical savings per year would be approximately 450,000 kWh.

Building HVAC Recommissioning Program

Stanford is systematically reviewing the HVAC systems of 90 of its largest buildings, then adjusting or repairing the systems to ensure they work as designed. Technicians who conduct the reviews also recommend ways to further improve energy performance through ERP projects. All 90 buildings have been through an initial round of retrocommissioning and each building is revisited every four years.

Energy Conservation Incentive Program (ECIP)

Introduced in spring 2004, this program aims to give schools and administrative units a financial incentive to use less electricity. The program sets a budget based on past consumption and lets participants "cash in" unused kilowatt-hours; those that exceed their electricity budgets pay the difference out of their own funds.

By the end of the program’s third full year, participants collectively used 3 percent less electricity than budgeted – netting a total rebate of $830,000. The program aims to reduce electricity use by 5 percent from a 2003 baseline. A number of schools and administrative units have achieved this goal, but others have had their baselines adjusted upward to accommodate additional electricity use from new buildings and expansions of research-driven activity.

Energy Conservation Incentive Program

New Construction Energy-Performance Standard

Design teams working on significant new construction and renovation projects on campus must exceed the California energy performance code (Title 24) by at least 30 percent.

Conservation Cup

In the annual Conservation Cup (formerly Energy Bowl and Water Derby), organized by Student Housing and Green Living Council, dorms and row houses compete to see which can cut energy and water use the most, compared with the previous spring. The contest also rewards residences with the lowest energy and water use on a per-student basis. Get further information at the Green Living Council's Conservation Cup website.

CFL Giveaway

Student Housing has teamed with Students for a Sustainable Stanford, the Sierra Club and Resource Solutions Group to sponsor one of the nation’s largest campus-based compact fluorescent lamp (CFL) giveaway programs.

Solar Demonstration Projects

The university is running several solar energy demonstration projects:

  • The Leslie Shao-ming Sun Field Station at Jasper Ridge has 22-kilowatt (kW) solar photovoltaic (PV) and solar thermal heating systems.
  • Synergy House has a 10-kW PV system, partly funded and installed by students and house alumni, who worked with Student Housing on the project.
  • Stanford’s Utilities Division installed a 30-kW PV system to offset the energy used for pumping water into storage reservoirs.
  • The new Jerry Yang and Akiko Yamazaki Environment + Energy Building showcases three PV installations totaling 12 kW. A planned fourth system will bring production to 15 kW.
  • Student Housing operates a solar water heating system at Roth House and has partnered with the Civil and Environmental Engineering department to demonstrate two solar water heating technologies in the Governor’s Corner residence.
  • A 40.8-kW PV system supplies electricity to Lou Henry Hoover House, the university president’s residence. To preserve the historic structure and optimize solar gain, the system was installed on the adjacent San Juan Reservoir roof.

While these solar projects don’t supply a significant portion of Stanford’s energy needs, they are valuable. They familiarize faculty, staff and students with the day-to-day operation of solar technologies, as well as help us gather data on performance and determine how the control and monitoring systems can be optimized.

Room Temperature Biological Sample Storage

Stanford recently completed a pilot project to evaluate a novel technology that promises to reduce energy consumption, achieve sustainability goals, and optimize laboratory space. Using a proprietary stabilization technology, biological samples that are typically stored frozen can be stored at room temperature. Laboratories can reduce dependency on costly freezers and reduce both energy consumption and their carbon footprint. The pilot was designed to assess the current economic and environmental impact of freezer-based storage, provide “hands-on” experience with this new technology, and extrapolate the potential benefit of room temperature biological sample storage to the entire campus. Based on the spring 2009 pilot results, the Department of Sustainability and Energy Management partnered with the School of Medicine to develop and offer a rebate program to incentivize early freezer retirement and adoption of room temperature storage technology.

Room Temperature Storage Pilot Report

Initial implementation, results, and the programmatic goals for the next funding cycle can be summarized as follows:

  • The Department of Sustainability and Energy Management and the School of Medicine launched a “cash for clunkers” rebate program in fall 2009 to encourage replacement of ultra-low-temperature (-80º) freezers
  • Cash incentives were provided for the following actions:
    • Freezer retirement without replacement
    • Freezer retirement with an energy-efficient replacement and/or room temperature storage conversions
    • Placing new samples directly into room temperature storage
  • Educational symposium held in March 2010 showcased pilot project success with room temperature storage and increased publicity and awareness
  • Program participation in FY10 exceeded expectations with freezer retirement, but did not meet adoption goals for room temperature storage
  • The FY11 program will be reshaped to address identified barriers:
    • 1st costs of room temperature storage technology
    • Labor costs for room temperature storage conversion
  • Refocused educational campaign will promote room temperature storage as industry leaders work to develop technology to store proteins, complex samples, assays, and cells
