The Z1403 standard will update flow rate and flush volume assumptions that have been industry standard since the 1940s and establish IAPMO’s widely adopted Water Demand Calculator as an ANSI/CAN standard.  

Previous sizing practices have routinely overestimated the required capacity of domestic water heating systems, relying on the Modified Hunter’s Curve to determine water systems sizing. Data-driven engineering, however, helps building owners and managers achieve new levels of safety, efficiency and cost/space savings for occupant needs.

Discover how water-efficient toilets can provide cost savings for affordable senior living apartments that can be invested in other parts of the community for lifestyle amenities.

Oversizing a domestic water system can lead to aging water and stagnation, the two biggest factors in waterborne pathogen growth. Yet modern plumbing codes still require or strongly recommend outdated sizing methods such as Hunter’s Curve, doing our building owners a disservice and putting the public at risk.

‘Beneficial electrification’ refers to the need to electrify buildings to reduce emissions from combustion heating.

Changes are unavoidable in the built environment, even during the construction phase. Communication is critical between fire protection designers and life safety system installers.
