Just curious, but has anyone encountered a "good" manufacturer's guide spec for a building automation system, in the sense of good use of Division 25, or better delineation between Div 23 and Div 25?
What I am noticing in my experience is a lot of what would be considered BAS tends to fall into HVAC controls, so there seems to be this overlap of the work results between the Sections in Div 25 (formerly 13800), and HVAC sections in 23 09 xx.

I have had a brief dabbling with http://www.ctrlspecbuilder.com, but it appears that they have the same issue as I describe above where stuff that isn't remotely HVAC (lighting control, for example) gets included in their Div 23 spec section.

I recently had a custom residential project. In a dilerious moment, I thought I would try to produce a shortform spec for custom-level construction. (Fortunately, the project was terminated and that relieved me from having to cope with designers who are VERY lacking in knowledge about basic construction materials and contracting practices.)
One of the "challenges" of the project was controlling many automated systems. These included operable sash in window walls, roller window shades at the window walls, interior and exterior lighting, HVAC controls, automatic door (sectional garage door) operators, audio/video systems, security systems, fire detection/alarm system (including the fire sprinkler system) and other systems I haven't yet imagined. Building automation has certainly become more common on many project types, including residential.
I just bought a new-to-us car that has many bells and whistles for performance and convenience. For example, the additional electronic key we bought cost almost $300. On the news tonight, it was reported that some new cars have up to 100 microprocessors.
Won't it be fun to integrate architects, interior designers, mechanical engineers, electrical engineers and specialists in audio/video to link specs for the many automated systems in commercial as well as residential construction? I think I'd rather be a spectator rather than a participant in this circus.
