I am working on an international project that has novelty lighting and lighting that displays cafe food. Are either of these exempt from EAc1.1? Is there a resource that gives the gist of ASHRAE 90.1 9.2.2.7?

Hi Andreas,
The food display lighting would likely be exempt under ASHRAE 90.1 - 9.6.2b, for merchandise lighting, at 1.0 W/SF. The "novelty" lighting may also be exempt under 9.6.2a, which covers decorative lighting, also at 1.0 W/SF. Both would need to be "automatically controlled, separately from the general lighting, to be turned off during nonbusiness hours."
The ASHRAE User's Manual is a good resource to understand the details of the standard.
