I am trying to model a multi-family mid-rise building to evaluate
improving the boiler plant. Currently, five boilers are piped together
acting as one boiler with 5 stages. This boiler serves three separate hot
water loops that serve each floor of the building. Has anyone had success
in attempting to model a building similar to this? Currently I am using
one hot water loop to simulate this situation but would like to hear how
other people modeled a similar building. Thanks.
