Hi, We have a project served by FCU connected to existing chiller - we do not have AHU. All our area are air conditionned as our project is in Singapore. I would use the VRP Compliance Calculator but i am not sure on how use it. The Table require "Mechanical Ventilation AHU Summary" but we do not have AHU on our project. Am i supposed to fill-up the table with the FCUs? My second question is about the meaning of "Mechanical Ventilation Multiple Zone Unit". I think it means one Unit shared between 2 zone or more. How define a zone which use 2 or more FCU?

If the fan coil units are provided with ventilation air from a separate dedicated air-handling unit, you'd only need to input one overall system. A multiple zone unit refers typically to a VAV system.
