Hi, can you help me in identifying the ratio of performance vs. prescriptive in new commercial building construction in the US or by some top states?
I understand this varies by state, but I am just looking for a directionally correct figure at this stage to form some hypothesis.
I have already looked at the following sources, but there are no recent stats on this topic: • New Buildings Institute (newbuildings.org) • BCAP Codes (bcapcodes.org) • CSE Mag (www.csemag.com) • Building Energy Codes Program (www.energycodes.gov) • American Council for an Energy-Efficient Economy (aceee.org) • American Institute of Architects (www.aia.org) • Building America Solution Center (basc.pnnl.gov)
Look forward to a speedy response.
You need to clarify your question. I don't know what you are asking.
