Dear All:- Our project located in Pakistan and the client not interested in Unoccupied cooling /Heating so it not considered in proposed case energy simulation But we consider Unoccupied cooling /Heating due to mandatory requirements (the building is G+6 so System 8 is considered as base case system. Due to that operating hours of HVAC system is vary b/w Base case and proposed case so we get some saving in Interior fan & Space cooling load 1.Is it correct and allowed 2.If wrong means what we do either remove Unoccupied cooling /Heating in base case or consider the Unoccupied cooling /Heating in proposed case

The mandatory requirement is that the project's HVAC controls must include the required capabilities. 1. No, the baseline and proposed must have identical temperature settings and schedules. 2. It does not matter as long as the settings are identical.
