Duane Warren, CEM, CMVP, BCxP, PVMA, is the Engineering Director and Senior Energy Engineer at JLL in the Energy and Sustainability Services Group. He spearheads retro-commissioning projects nationwide, reviews related reports and calculations, and innovates new methods and procedures for engineering challenges globally. Duane also evaluates new products and services for JLL, having established a robust review system. His engineering philosophy is encapsulated in his saying, ìEngineering is the Art of the Simplest Thing that Works Correctly.î Duane has performed innovative energy engineering in locations in the US, Canada, and Asia. In his career, his projects have saved enough energy to power the city of Austin, Texas ñ the 10th largest city in the US.

Duane holds a patent in Chiller Optimization and a trademark in Chilled Water System Optimization. He has presented seminars on this at several AEE conferences and has been published in the AEE newsletter. He has invented a new commissioning and testing procedure for electrical Harmonics testing and is developing fault detection and AI routines for Building Management Systems (BMS) and remote monitoring for mechanical, electrical, and irrigation systems. He has a wide base of engineering knowledge and uses these various threads to develop new and innovative solutions to problems. He believes, ìLife is change. Dealing with it, learning from it, and growing with it is what keeps us focused and engaged. It makes us human.î

Duane’s notable projects include a regenerative cool gas defrost lab system reducing energy use by 30% at ALS Environmental Services in Edmonton, Alberta, an acetone recovery system reducing acetone loss by 1,800 tons annually, improving energy efficiency and emissions at Hoechst Celanese in Edmonton, a make-up air unit reducing HVAC energy use by 18% at Labatt Brewries Canada, free cooling systems with 20% lower energy use for companies like Exodus Communications, Bank of America, and Dell, an automation system for a research lab improving energy efficiency and safety at Biomed Industries in San Jose, California, a chilled water system optimization reducing HVAC energy use by 35% at AMD Headquarters also in San Jose, an optimization system reducing HVAC energy use by 30% at Texas Health Presbyterian Hospital, chilled water system optimizations at University of Texas campuses and South Eastern Oklahoma State University reducing HVAC energy use by 28-32%, optimization system reducing HVAC energy use by 26% at the Venetian Hotel in Las Vegas, Nevada, and an inspection and analysis of an electrical metering network to reduce energy use at Disneyland California.
