IAPMO’s Water Demand Calculator Version 2.0 now available for download
IAPMO announced the Water Demand Calculator version 2.0 — with new and enhanced features — is now available for download.
While the basic template of the calculator remains intact, several new features have been added along the edge. The most significant new feature is the addition of a drop-down menu that offers a selection between a single- and multifamily building. The multifamily option activates two additional input boxes that require the user to specify the total number of apartments that are: (A) in the building, and (B) in the calculation. The latter entry is dynamically linked to the probability of fixture use column in the calculator, gradually reducing the percentage as the number of apartments increase. This new calibrated feature assures accurate predictions of peak water demand in large multi-family dwellings.
