"Integrity is the initial word that come to mind when I recall my association with Rob at the workplace. He always impressed me that his moral compass was always pointed true north which gave him clarity in the way he approached tasks, projects and even his life. (Perhaps this clarity is one reason he is such an excellent photographer!) Rob is a genuinely nice guy and will do right by you, even go the extra mile when necessary. He is extremely capable and has the ability to understand both the details and the big picture to produce realistic results. He possesses the rare combination of personality, attitude and ability. Bottom-line is he is a pleasure to work with from start to finish."

"I've routinely recommended Rob Lehman to our residential clients as both an Energy Consultant and Green Building Expert for the past several years. Rob's fees are very reasonable relative the services he provides, and he has a committment to getting the job done right, even when issues arise. "

− Eugene H. Sakai, AIA, LEED AP President, Studio S Squared Architecture, Inc.

"I originally found Rob Lehman when searching for HERS raters who would have the experience and professionalism to field complex questions and handle sensitive project scenarios for custom residential design clients. Our office provided the home energy reports required by California law, and sometimes those reports required additional services in order to comply - Rob provided some of those services, namely HERS testing and BuildItGreen's GreenPoint Rating. Rob was always very quick to respond to requests and was very committed to the principles behind energy efficiency. His experience as as building inspector gave him ample familiarity with the code compliance side of green building, and his versatile building energy knowledge extends to projects both large and small. In addition to his primary practice, Rob was a featured subject-matter expert whom we interviewed for our own energy blog numerous times on topics such as HERS testing, GreenPoint Rating, and LEED certification. He is very honest in his appraisals and has been a very helpful and supportive professional colleague."
