AbstractThe objective of this paper is to examine the energy and comfort impact of the HVAC equipment granularity in offices through building performance simulation. To this end, the occupancy data gathered from 37 private offices in Ottawa, Canada were analysed. For each occupant, four parameters that play an important role over the HVAC operation were extracted. These parameters are the earliest expected arrival time, the latest expected departure time, the latest expected arrival time, and the longest expected duration of intermediate vacancy. Through random sampling from the 37 occupants, hypothetical zones with varying numbers of occupants were created, and EnergyPlus simulations were conducted. Results indicate that the earliest expected arrival time in one-person zones is on average two hours later than it is in twelve-person zones. Similarly, the latest expected departure time in one-person zones is on average two hours earlier than it is in twelve-person zones. Heating and cooling energy use with adaptive occupancy-based temperature setback scheduling in one-person zones is estimated to be 20% less than it is in twelve-person zones.
