Energy Modeling Licensure

Not that I know of. I own a firm in PA that does energy modeling and I am not a PE. Nothing personal but having a PE does not make one a good energy modeler. I have seen some really bad models prepared by PEs and some great ones prepared by non-engineers. The only entities that I am aware of that require any sort of credential for an energy modeler are going to be specific parties that hire them. It think the IRS commercial tax credit process requires a PE or something similar. ASHRAE Standard 209 is proposing a requirement that energy modelers have the BEMP credential from ASHRAE.

Hard to prove that something does not exist. :-) To expand on my experience - I have been using energy models on projects for over 30 years and we have done work in at least half the states and I have not heard about it being an issue yet. If you were submiting the models for code compliance (as in 90.1 Section 1)1 then I could see where you might need to be a PE. If you want to reach a bunch of experienced modelers to ask them I would suggest that you post the question on the bldgsim listserv accessible from onebuilding.org. Let us know what you find!
