# overview
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(R) 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.
