Stanford's 4th generation district energy system
This profile, presented by Johnson Controls, goes behind the scenes on the development and deployment of a new central energy facility at Stanford University that is expected to save the campus $420 million in operational costs.
The plant, which is the cornerstone of the Stanford Energy System Innovations project, operates efficiently in any weather condition, thanks to ultra-efficient building technologies, including heat recovery chillers, hot and cold water thermal energy storage, and a patented smart technology system that uses weather and electricity pricing forecasts to optimize operations. This six-page profile written by Joseph Stagner, executive director of sustainability and energy management at Stanford University, explores the system in detail and compares it to the 50 MW natural gas-fired cogeneration it replaced.
The plant's heat recovery process, which was custom engineered by Johnson Controls and Affiliated Engineers Inc., is 70% more efficient than the cogeneration process Stanford used since 1987, according to Johnson Controls.
"Shifting from gas cogeneration to grid electricity may be contrary to current trends, but heat recovery and renewable power are the keys to economic and sustainable energy for Stanford University," Stagner wrote.
