Major lab retrofits lead to big energy savings

Wednesday, September 13, 2017

Stanford’s Whole Building Energy Retrofits Program (WBERP) invested in major energy retrofits at the Mechanical Engineering Research Lab and Varian Physics Lab, which together will save over $350,000 per year in energy costs. The retrofits included installing the latest in high-efficiency lab control systems, including using occupancy sensors in labs to minimize use of lighting and fans during unoccupied periods. The $30 million WBERP program began in 2004 to address the 12 campus buildings consuming the most energy, and now includes the top 27, representing 60% of total campus energy use. On average, buildings that have participated in the WBERP program are seeing 24% reductions in their energy usage, with some buildings achieving savings of up to 50%.
