Words of caution: If you are the Engineer or designer and the energy modeler, writing down the path of applicable codes is a good habit to get into. Make sure the design team is aware of what codes apply to the project. There may be conflict with the code and LEED requirements, so what applies to you and your energy model. Are the codes modified by the client? Setting the markers along the path is a good way to know where you came from and so others can follow.
