We cut the energy consumption by over 70% at this 10 year old Navy Chiller Plant!
If you are serious about cutting energy consumption and reducing operating costs, you'll want to be at this presentation!
“Large Temperature Differential” design will be discussed. Typical TES systems that were a part of the Southern California Edison “Permanent Load Shift” chilled water storage pilot program operated with 25°F to 30°F chilled water temperature differentials, while the PG&E site peaked out with a 44°F temperature differential (not a typo!), with typical summer operation floating between 30°F and 34°F TD’s. The PG&E 900 ton chiller plant all-in efficiency averaged around 0.50 kWh per ton-hour while making 35°F chilled water for the TES system during the TES charge cycle.
A preliminary analysis using all of the above strategies and an innovative dehumidification/ reheat system to treat 1,000,000 CFM of makeup air at a large chip fab yielded potential savings of over 27,000,000 kWh per year, and over 400,000 therms per year in natural gas savings.
These design, Demand Response and optimization strategies can be applied across a wide variety of facility types, from tilt ups with large RTU’s to Commercial office space, to Universities and Colleges, to military, prison, manufacturing and technology sites.
Please join us for an entertaining and educational meeting!
Scot M. Duncan, P.E. Biography
With 39 years of field, design and plant operational experience, the bio gets really long! We’ll just bracket it to cut down on your boredom reading it…Scot started in the business at age 12 helping his dad install an early version of an automation system (the Honeywell Delta 2000 for you old guys) at the Irvine Company Newport Center high rise facilities. Since then, he has been involved in hundreds of successful and sometimes counter-intuitive energy efficiency projects.
He is a “Subject Matter Expert” for the U.S. Army Corps of Engineers on 14 different topics, ranging from Net Zero Energy HVAC designs, to high efficiency dehumidification/reheat systems, to HVAC optimization to TES. Scot is a co-author of the International Energy Agency (IEA) ECBCS Annex 46 “Energy and Process Assessment Protocol” (soon to be on Oprah’s “must read” list and a New York Times Best Seller wanna-be…).
Scot is a Past President of the AEE SoCal Chapter (1990) and is Vice President of Retrofit Originality Incorporated, and President of Enerliance. He has provided over 100 chiller plant, HVAC and TES energy efficiency and design strategy training seminars since 1985, and has not been booed off the stage even once that he’ll admit to.
