font-family:Tahoma'>I am using eQUEST to model a high-rise multi-unit
residential building (in a cold climate). The mechanical system most
likely for selection will include 2-pipe fan coils (with a supplementary
electric coil) in the suites and a corridor make-up air unit. The in-suite
fan coils under consideration have an outdoor air intake and an air-to-air heat
exchanger to recover heat from the suite washroom exhaust. This is not
how the FC fan coil system is set up in DOE 2.2 – and there is no
provision for heat recovery at the fan-coil level. I am using the
OA-FROM-SYS keyword which moves the entire ventilation load to the corridor make-up
air system where heat recovery can be applied. Doing this appears to
greatly improve the energy performance of the building. I am wondering if
modeling the system in this was is over-stating performance of the heat
recovery.</span></font></p>

better model such a system. Any assistance would be greatly appreciated.</span></font></p>
