MILWAUKEE, June 15, 2015 /PRNewswire/ -- Stanford
University cut its water use by 15 percent and is projected to save
$420 million in operational costs
thanks to a new central energy facility (CEF) developed with help
from Johnson Controls. The new plant helps Stanford make substantial progress to meet
California's statewide goal to
reduce water use by 25 percent.
The plant 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. The central plant system is a key
component of the Stanford Energy System Innovations (SESI) – making
the university one of the most energy-efficient research facilities
in the world.
"Nothing goes to waste inside this facility. We are recycling
heat that is typically released by cooling towers and putting it to
good use to keep students and staff comfortable," said Trent Nevill, vice president and general
manager, Johnson Controls Building Efficiency. "All this is
accomplished while helping Stanford
reduce its carbon emissions by 50 percent compared to levels during
the 1990s."
Johnson Controls, a global multi industrial, together with
Affiliated Engineers, Inc., helped Stanford engineers deliver a custom-engineered
heat-recovery process that is 70 percent more efficient than the
cogeneration process Stanford used
since 1987. York heat-recovery chillers will meet more than 90
percent of campus heating demands by capturing almost two-thirds of
the waste heat generated by the campus cooling system to produce
hot water for the heating system.
Along with a Metasys building automation system, Johnson
Controls developed the Enterprise Optimization System, a predictive
control software system to optimize cost and energy use based on
the 10 day weather forecast and future grid electricity prices. The
software is designed to predict hourly campus heating and cooling
needs, and then determine how to best run the heat recovery,
heating, and cooling equipment inside. It also will determine how
much hot and cold water to store in the CEF's water thermal storage
tanks for later use.
"There's a great comparison to autopilot technology on an
aircraft. The system continuously monitors plant equipment,
predicts campus energy loads and grid electricity prices, and
steers the system to optimal efficiency," added Nevill.
