Level of Detail Guidelines for BEM?

I have done a web (and forum) search for some kind of standards or guidance related to level of detail for building energy models at different levels of design. Plenty of information exists related to LOD for BIM, but I couldn't find anything specific to BIM. I'm interested in referencing these for in our proposals / scope of work, and would love to NOT have to develop them myself.

Thanks in advance for any links or documents anyone can share.

You may want to start with ASHRAE Standard 209-2018, Energy Simulation Aided Design for Buildings except Low Rise Residential Buildings, and the AIA's An Architect’s Guide to Integrating Energy Modeling in the Design Process.

Thanks, David. I did think of Standard 209 after submitting this. I have a copy and am familiar -- it is a little too generic, BUT LOD specifications could work very well as an appendix to the Standards and referenced from the modeling cycle sections. The AIA document I hadn't seen before. I just reviewed it, and it doesn't really get into LOD as I am thinking about it. Thanks again for replying.
