Case Studies from Stanford: How to Save Energy and Improve Laboratory Safety Without Disrupting Research

Mark Hydeman, P.E. , Taylor Engineering, LLC
Scott Gould, Stanford University

This presentation will cover work on energy-conserving retrofits of occupied research laboratory buildings on Stanford's campus that have resulted in reduced energy with improved safety and comfort and minimal disruption to research. It will cover the six years of collaborative effort between Stanford's facility operations staff, the building tenants, Taylor Engineering, and a number of contractors who are currently servicing these buildings. The bulk of the savings have been achieved through DDC retrofits to the zone level and conversion of constant volume fume exhaust systems to variable air volume. Work on four buildings will be discussed in detail: William Keck (45,000 square feet (sq. ft.), built in the 1980s), Stauffer 1 and 2 buildings (28,000 sq. ft., built in the 1960s), and the Beckman Center for Molecular and Genetic Medicine (approximately 182,000 sq. ft., built in the late 1980s). Keck and Stauffer I are complete, Stauffer II is in construction and the Beckman CMGM building is in a preconstruction study phase. The Stauffer I project was estimated to save 40 percent of the annual utility bill. The current metered savings from June 2007 through January 2008 show it to be closer to 50 percent energy cost savings with a 60 percent reduction in chilled water usage, a 34 percent reduction in electricity, and a 54 percent reduction in steam. This project also has pre- and post-retrofit measurements of space acoustical data. This case study-based presentation will focus on the topics of: the process for evaluation and implementation of the efficiency measures, performance of the measures, and the lessons learned (both good and bad).
