We just came across this excellent guide to share, from the National Institute of Building Sciences‘ Whole Building Design Guide — have you seen this?

Because a designer neither sells nor installs lighting equipment, the design is based on an objective understanding of the project goals and budget. While electrical engineers can design a lighting system, that design is most likely based on electrical requirements and code standards but may lack the aesthetic sensitivities to the overall architectural design.
