Scope:

This standard provides the methodology for accurately predicting peak water demand in single-family homes and apartment buildings, reducing the carbon footprint of the structure, and saving consumers on both their water and water heating-related energy utility bills for the entire life of the plumbing system.

Project need:

Plumbing systems in new home construction are routinely overbuilt, increasing housing costs because the most commonly-used pipe sizing formula is almost 90 years old – developed well before today’s innovative low-flow fixtures and appliances came on the scene. Using the IAPMO Water Demand Calculator for new residential construction significantly 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 energy utility bills for the entire life of the plumbing system. This standard meets the needs of stakeholders: Plumbing engineers, plumbing and construction contractors, regulatory authorities, plumbers, pipefitters.

Note: The information provided above was obtained by the Standards Council of Canada (SCC) and is provided as part of a centralized, transparent notification system for new standards development. The system allows SCC-accredited Standards Development Organizations (SDOs), and members of the public, to be informed of new work in Canadian standards development, and allows SCC-accredited SDOs to identify and resolve potential duplication of standards and effort.

Individual SDOs are responsible for the content and accuracy of the information presented here. The text is presented in the language in which it was provided to SCC.
