Estimating Peak Water Demands in Buildings with Efficient Fixtures
Estimating Peak Water Demands in Buildings with Efficient Fixtures
Presented on Tuesday, March 22, 2016
Learn about a new probability-based method for determining peak water demands during this half-hour presentation.
An IAPMO task group recently completed a draft report on estimating peak water demands in residential buildings fitted with efficient fixtures. This draft report proposes a new probability-based method similar in principle to Hunter’s curve for determining peak water demands.
This new method replaces fixture units with probability of fixture use, which are estimated from a large national database of residential water use. This new procedure for estimating peak demands can be formulated as a universal dimensionless design expression that is easily programmed on an Excel® spreadsheet.
An example will illustrate the application of this new method at a single-family residence and at a large office complex.

Steven Buchberger, Ph.D., is a professor and the head of Civil and Architectural Engineering and Construction Management at the University of Cincinnati where he teaches courses and guides research in urban water resources. Since joining UC in 1988, he’s authored more than 130 archived publications, directed $11 million in research projects, and advised 60 graduate students. Recently, Buchberger served on the IAPMO task group charged with developing a probability model to predict peak demands based on the number of plumbing fixtures of different kinds installed in one system. He holds a Ph.D. in civil engineering from the University of Texas at Austin and is a registered professional engineer in Colorado.
