IAPMO to Host Third Annual Water Demand Calculator™ Virtual Summit on Nov. 7

Ontario, Calif. — The International Association of Plumbing and Mechanical Officials (IAPMO®) will host the third annual Water Demand Calculator™ Virtual Summit from 11 a.m. to 3 p.m. EST Nov. 7.

This four-hour event will review some of the steps taken over the past year in expanding the Water Demand Calculator from residential to commercial buildings, review new adoptions of Appendix M, discuss the ANSI-accredited development process, and discuss how the Water Demand Calculator can help solve a number of issues in multifamily construction. The theme for this year’s summit will be “First Up.”

“IAPMO continues to lead the industry on developing innovative solutions to 21st century plumbing issues – beginning with the Water Demand Calculator, of which development began more than a decade ago, and continues today,” said Vice President of Technical Services and Research Christoph Lohr, P.E. “The continuation of the Water Demand Calculator Summit is an opportunity for plumbing industry professionals to learn how IAPMO has set the bar in right-sizing of plumbing systems, which is part of two American National Standards: the Uniform Plumbing Code (UPC®) and the Water Efficiency and Sanitation Standard (WE•Stand). IAPMO, along with industry partners the University of Cincinnati and the American Society of Plumbing Engineers, was ‘first up’ to the challenge of creating a new water sizing standard approved under the ANSI-accredited development process as Appendix M in the UPC and Appendix C in the WE•Stand – and this summit will showcase how that work continues to evolve.”
