Not a question, but a request for the community:

I sit on an ASHRAE committee that is developing standards for automatic fault detection and diagnostics (AFDD) for rooftop package units.
We’re trying to gather data on the prevalence of various fault types (to help determine the cost-effectiveness of the AFDD systems). The head of the committee has put together a survey aimed at field contractors, to try to gather more information.

The more input we get, the better, so we would appreciate any contractors who would take this brief survey:

Also: any comments on the survey may be sent to me:
beubanks*at* taylor-engineering.com

I will share them with the committee head who created the survey.

Thanks!
