Right Sizing Residential Plumbing with the Water Demand Calculator with Gary Klein and Cristof Lohr

This session will cover the benefits of using the California Plumbing Code’s Water Demand Calculator (WDC) to size plumbing in homes and apartment buildings. It is a solution that reduces water aging, delivers hot water faster, generates significant construction cost savings, reduces the carbon footprint of the structure, and subsequently saves on water- and water heating-related utility bills for the entire life of the plumbing system. Effective July 1, 2024, the WDC will become part of the California Plumbing Code (as Appendix M). Instead of using flow rates and flush volumes from the 1940s, the WDC will allow plumbing designers to “right-size” the cold and hot water distribution systems in homes and apartment buildings using modern information about flow rates and simultaneous use.
Learning Objectives
1.) Differentiate the conditions that existed for the “default” water supply demand sizing method from the conditions that are incorporated into the Water Demand Calculator (WDC) when selecting a method for sizing peak water demand.
2.) Describe the savings in cost, water, energy, and carbon emissions achieved by using the WDC in the plumbing design of a multifamily building.
3.) Summarize the reduced public health and safety risk as well as water quality benefit of plumbing systems designed using the WDC when justifying the use of the WDC.
4.) Locate instructional resources for using the WDC in the plumbing designs of upcoming projects.

maybe i missed it but after about 20 minutes of you guys talking about apartments, I started skipping. When your title says "residential plumbing", I guess what comes to mind first are single family residential environments. Guess I'll go look elsewhere.
