Jeff S. Haberl

Dr. Jeffrey S. Haberl, P.E.inactive, is a Professor of Architecture and Associate Department Head for Research in the Department of Architecture at Texas A&M University. He is also an Associate Director of the Energy Systems Laboratory. He is an ASHRAE Fellow, an IPMVP Fellow, and an IBPSA Fellow. Dr. Haberl's educational background includes B.S., M.S., and Ph.D. degrees from the University of Colorado at Boulder and post-doctoral research at Princeton University's Center for Energy and Environmental Studies. Dr. Haberl came to Texas A&M in 1989 and has dedicated nearly 3 decades ($32.8M as a Co-PI and $2.3M as a PI) performing building energy research at Texas A&M University, Princeton University, the University of Colorado, Rockwell International, the Colorado State Office of Energy Conservation, the City of Boulder, and the USDOE Administrative Services.

His work emphasizes building energy modeling, statistical modeling, methods for diagnosing operational problems, operator feedback using comparisons of predicted and actual energy use, artificial intelligence, advanced energy usage graphics, prescreening calculations for improving commercial and residential energy audits, public-domain M&V algorithms, computerized solar shading procedures, accuracy tests for HVAC systems, BIM-to-thermal procedures, and procedures for calculating air pollution savings from energy efficiency and renewable energy projects (i.e., SOx, NOx, CO2, PM and Hg).

He is a Co-PI of the Laboratory’s Texas Emissions Reduction Program (TERP), along with Mr. Bahman Yazdani, where he provides technical leadership for the code compliance calculator and emissions calculations from energy efficiency and renewable energy. He is a Co-PI for the USEPA’s National Center of Excellence on Displaced Emissions Reductions (CEDER), with Dr. Charles Culp and Mr. Bahman Yazdani, which was established in the Spring of 2007 to help the EPA transfer the Texas emissions reductions calculation procedures to other states; a Co-PI for the Laboratory’s Continuous Commissioning® program for improving energy efficiency in existing buildings; PI and/or Co-PI on numerous ASHRAE Research Projects (RP-827, RP-865, RP-1050, RP-1093, RP-1017, RP-1468); Co-PI on an NSF project for creating physically-based, BIM-to-thermal simulations; PI on the NAS TRB project for benchmarking airport terminal energy use; and the Co-PI of Texas A&M University’s 2007 Solar Decathlon Effort, with Pliny Fisk as the PI.

He was the Principal Investigator for the Computer Support and Improved Energy Audit of the Texas LoanSTAR project from 1990 to 2002, a $98.6 million revolving loan for the state of Texas that was the largest first large-scale project in the United States to continuously measure and report energy savings in over 160 building energy conservation retrofits, and he has served as the Chair for 17 MS and 16 PhD students.

Dr. Haberl is a registered, inactive Engineer in the State of Texas (P.E. #67618), has authored or co-authored 50 publications, 24 books or book chapters, 185 conference proceedings, 266 publications, 331 reports, developed 54 software packages, and holds numerous U.S. patents. He was the chairman for ASHRAE’s Performance Metric Protocols committee, and he has been the chairman of TC 4.7, and the Handbook chairman of ASHRAE TC 1.5 (Computer Applications) and has contributed to the ASHRAE Handbook Chapters #49 and #60. He also helped develop ASHRAE Standard 140 and ASHRAE Guideline 14. He received a Boulder County Energy Conservation Award, two USDOE innovative research awards for work performed at the University of Colorado (with Dr. Claridge), a USDOE special citation for his work at the Forrestal and Germantown complexes, a 1990 GSA Design Award, and a 1992 National Endowment of the Arts Federal Design Award for his work at the Forrestal building, and a 2001 ASHRAE Distinguished Service Award.

Dr. Claridge is internationally known for his work over the last 15 years directing the development and participating in the implementation of the Continuous Commissioning® process for improving the comfort and energy efficiency of buildings. It has been applied in well over 300 large buildings that include higher education facilities, military facilities, medical facilities, and office buildings. He has made major contributions to the analysis of heat transfer between buildings and ground and to the analysis of air leakage in buildings. He is also a world leader in development and application of measurement and verification techniques to determine savings from efficiency projects.

He has taught numerous commissioning workshops and is the author of well over 300 journal and conference papers. He had 10 years of experience in the HVAC field, prior to coming to Texas A&M in 1986.
