The International Association of Plumbing and Mechanical Officials (IAPMO) has released a new version of its Water Demand Calculator.
Version 2.0 includes some notable enhancements. Among them is the addition of a drop-down menu offering a selection between single- and multifamily buildings.
This offers inputs for a new calibrated feature for accurate predictions of peak water demand in large multifamily buildings. WeStand, another new feature, displays additional computed information for peak conditions.
It uses total fixture count and the 99th percentile demand flow to give the average number of simultaneous busy fixtures in use at any moment during the peak period, and the probability of no flow.
The tool is now available for download.
