Siemens Solution Helps San Diego International Airport with Sustainability Efforts
August 17, 2021 | San Diego, CA
As part of its ongoing environmental improvement strategy, the San Diego County Regional Airport Authority (Airport Authority) implemented a chilled water system optimization at the San Diego International Airport’s central utility plant. The Demand Flow® chilled water system optimization from Siemens will reduce energy consumption, extend equipment life, and improve occupant comfort.
Five chillers of varying sizes and types were installed at the plant during the last 25 years. Siemens upgraded the chilled water system with high accuracy sensors that allow for monitoring through centralized energy optimization controls. Demand Flow control runs the chillers at higher efficiency, allowing for more effective cooling with less equipment and energy. Rather than shifting energy from one system to another, the holistic chilled water optimization solution reduces overall total system energy consumption, while delivering increased system redundancy.
Demand Flow control depends on the building automation system for programming, calculated variables, and decision-making based on the results of those variables. A graphical user interface (GUI) enables operators to monitor, command, and control the components of the chilled water system. The improved insight and flexibility of control helps operators trend and track performance, foresee maintenance issues, and make repairs on the chilled water system.
“We are seeing significantly improved efficiency of our chilled water system which saves money and helps meet our strategic energy plan goals,” says Airport Authority Energy and Water Manager Cogan Semler. “The dashboard allows us to see how the chilled water system components interact and allows our operators to better understand operational and maintenance considerations to keep things optimized.”
Siemens has a long-standing relationship with the Airport Authority, having provided various building automation, fire/life safety, and security technologies as well as baggage handling, passenger security screening, and air bridge HVAC operations.
The Airport Authority instituted one of the first sustainability policies for a major U.S. airport. This formalized the Airport Authority’s commitment to an environmentally sustainable future for the airport and the region. The Airport Authority is committed to building and operating sustainably and strives to protect the wide variety of natural resources that exist at San Diego International Airport’s location.
