Personnel

The principals of GARD Analytics have been associated with GARD and its ancestor companies for over 20 years. The principals devote full time efforts to building and systems energy and environmental studies and related R&D work.

Jason Glazer, P.E., President and Principal Engineer

Energy Analysis, Energy Code Development, Software Development, 

Mr. Glazer is a registered professional mechanical engineer with over 20 years of experience. His specialties include the use of building simulation software, analysis of utility rates and tracking building energy codes. He performs comparative energy and economic analyses of commercial building heating and cooling systems using the DOE-2 hourly building simulation program. Mr. Glazer is currently a member of the committee responsible for the revision of ASHRAE Standard 90.1 (the commercial building energy code) and the chair of the Energy Cost Budget subcommittee.  Mr. Glazer has authored software to evaluate complex utility rates, manage large scale parametric analyses, translate between different energy simulation languages and to estimate energy savings opportunities in industrial facilities. He has developed a software screening tool for the USDOE to allow analysis and evaluation of integrated building cooling heating power (BCHP) systems. Mr. Glazer developed many of the utilities that come with EnergyPlus including EP-Launch and IDF Editor. Mr. Glazer received a Bachelor of Science in Mechanical Engineering from the University of Illinois at Chicago and is a member of ASHRAE. Mr. Glazer received his professional engineering license in 1998.  Mr. Glazer’s e-mail address is jglazer at gard.com and phone number is (847) 698 – 5686. He is also the webmaster at this site and administers the mailing lists as onebuilding.org.

Robert H. Henninger, Principal Engineer

Building Energy Modeling, Energy Analysis, Software Testing

Mr. Henninger has over 40 years of experience in performing contract R&D and applications engineering programs, concentrated in the principal areas of commercial and industrial building energy efficiency studies, development and application of building and energy systems simulation/analysis software, and laboratory and field testing of air treatment systems. Mr. Henninger served as Manager of GARD’s Energy Applications Group for 15 years where he supervised the energy and economic analysis services provided in the past by GARD and now by GARD Analytics. Mr. Henninger has managed several programs for the Gas Technology Institute including the Monitoring and Analysis of the Impact of ASHRAE Standards 62.1, 62.2 and 90.1 and the Energy and Economic Analysis Energy Efficient Alternatives for Commercial Buildings. He received a Masters in Mechanical Engineering from the University of Illinois. Mr. Henninger’s e-mail address is rhenninger at gard.com and phone number is (847) 698 – 5688

Michael J. Witte, Ph.D., BEMP, Principal Engineer

Building Energy Modeling, Software Testing, EnergyPlus Support and Training

Dr. Witte is a mechanical engineer with almost 25 years experience. Dr. Witte supports GARD’s energy program activities by performing software development, energy simulation studies, economic analysis and data analysis. He has developed a database to estimate the overall resource energy efficiency and related emissions of delivering natural gas and electricity to end-use natural gas or electric appliances. He performs commercial building system energy analysis studies using DOE-2 and BLAST with an emphasis on gas cooling equipment. He developed the underlying simulation models used in GTI’s DesiCalc™ desiccant system analysis tool and the Building Energy Analyzer. Currently, Dr. Witte is principal investigator on a program to provide testing, user support and training, and software development for DOE’s EnergyPlus program. Dr. Witte received a Doctorate in Mechanical Engineering from the University of Illinois. He has authored technical publications on simulation software, solar energy, double-diffusive convection and HVAC design criteria, and he is a member of ASHRAE, ASME, and the International Building Performance Simulation Association.  He is an ASHRAE certified Building Energy Modeling Professional (BEMP). Dr. Witte’s e-mail address is mjwitte at gard.com and phone number is (847) 698 – 5685.
