Jeff S. Haberl Bio PDF Print E-mail

Jeff S. HaberlDr. Jeffrey S. Haberl, P.E., is a Professor of Architecture at Texas A&M University and an ASHRAE Fellow and IPMVP 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 ($26.5M CoPI; $2.5M 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 statistical building energy 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 energy audits, public-domain M&V algorithms, computerized solar shading 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 Senate Bill 5 program (with Dr. Charles Culp, and Mr. Bahman Yazdani), where he provides technical leadership for the code compliance calculator and emissions calculations from energy efficiency and renewable energy; a Co-PI for the USEPA’s new 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; and he is the Co-PI of Texas A&M’s 2007 Solar Decathlon Effort (with Pliny Fisk – 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 14 MS and 10 PhD students.

Dr. Haberl is a Registered Engineer in the State of Texas (P.E. #67618), has authored or co-authored 73 publications, 128 conference proceedings, 193 reports and holds numerous U.S. patents. He has been Handbook chairman of ASHRAE TC 1.5 (Computer Applications) and has contributed to the ASHRAE Handbook Chapters #49 and #60. He helped develop STandard 140 and Guideline 14, and has participated on numerous ASHRAE Research Projects (827, 865, 1004, 1017, 1050, 1092 and 1093). 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 an ASHRAE Distinguished Service Award.
