I'm looking for the best approach/workflow to model multifamily buildings with individual domestic hot water systems in Open Studio. Modeling a single central plant and adjusting the water use definitions and schedules to account for the demand of all apartments does not seem like the most appropriate representation (simplification) of the actual design, especially if alternate DHW systems are being considered. The other option as I see it is to model a separate service hot water loop for each apartment. Though potentially more accurate, this method is exceedingly time consuming and significantly impacts simulation run time.
Is it possible to apply a multiplier to a service hot water loop so that a single service hot water loop could be simulated and the results would be aggregated? Is there another workflow that I am not considering?
Appreciate any advice or opinions!
