Daniel Chapman, P.E., PMP

Senior Engineer

Mr. Chapman has 11 years of professional experience and has been conducting engineering analyses in support of energy program evaluation for five years. He is a senior mechanical engineer with expertise in commercial and industrial HVAC systems and other equipment. As explained in the following sections, he has analyzed industrial agricultural measures, manufacturing hardware modifications, heat exchangers, solar thermal systems, water treatment retrofits, motor variable speed drives, and many others.

Mr. Chapman is experienced with both energy simulation and engineering calculations for custom project reviews. He is an expert with EnergyPlus and eQUEST software, including using the DOE2 engine for large parametric runs to determine end-use load shapes for the California Energy Commission. He is also experienced with more conventional calculations including bin analyses, regressions, and use of technical reference manuals. He ‘triangulates’ energy savings measures using several calculation approaches when possible, selecting the option or combination of options based on the program guidelines and budget.

He is an expert programmer in R, and has produced multiple function packages used by the analysis team. He manages the GitLab code repository for ADM, which forms the backbone of the analysis quality control program. His expertise includes mechanical engineering, data science, as well as program management, which leads to a valuable high-level grasp of energy program evaluation. He leads an effort to automate some types of analysis using interactive websites and report-generating scripts.

Mr. Chapman has developed expertise in managing and conducting Evaluation, Measurement, and Verification (EM&V) studies. For custom monitoring of commercial sites, he has experience planning the data collection and is familiar with many logger types. Loggers used include WattNode energy meters of many types, Onset Hobo data logger products, and other brands. He has also designed custom energy monitoring systems using LabView by National Instruments, and has fabricated custom evaluation tools using a 3D printer and CNC router.

Mr. Chapman received his B.S. in Aeronautical Engineering from the University of California, Davis; his M.S in Engineering & Technology Management from Colorado School of Mines, and his M.S. in Physics from San Francisco State University.
