We have a culinary school, the minimum OA per 62.1 is only 10k cfm, but the fume hood exhaust can go above 100k cfm.

I have couple of questions about filling table 1.4.7: 1- Table 1.4.7A asks for the total cooling capacity, I use HAP 4.6 and the cooling capacities are calculated according to ASHRAE 90.1.

What if the project don't have any A/C? there are 3 retails, 1 wc. All are separated buildings. What should I do with ASHRAE 5.4, 6.4 and for energy simulation?

Does anyone know if isolation valves on a multiple chiller plant are required by ASHRAE, or they simply best practice? I have looked into this in ASHRAE documents, but have not found anything yet.

According to 5.4.3.4 (mandatory provision) enclosed vestibules shall protect building entrances that separate the conditioned space from the exterior.

As far as we read the Mandatory Requirements of ASHRAE 90.1 required by EAp2, performance requirements must meet the specifications of Table 7.8.

I am working on a job with the Army Corps of Engineers that has a vehicle maintenance workbay with general exhaust requirements of 1.5 CFM/SF dictated by the RFP.
