Living Building Challenge Water Petal
The Living Building Challenge Water Petal asks a project to operate within the water balance of its place and climate. We help the design team test that idea against the site: demand, supply, quality and where water goes next.
Send us your drawings and the Living Building Challenge target you are exploring. We'll confirm the scope and the fee.
This page is part of Water Design.
Send the drawings, site location, building use, typology, and the Living Building Challenge target you are exploring. We work to the version your project is registered under.
The Living Building Challenge is organised by the International Living Future Institute (Living Future). Living Future certifies projects. This page is Water Petal advisory: a water-balance briefing, options and an issues list your LBC lead can take forward.
A wider design conversation about defining “net-positive water” outside this rating sits on net-positive water frameworks. That study is not a Water Petal certificate.
A rainwater tank is not a Petal strategy on its own. It only helps if catchment, storage, connected demand and the unused water's destination add up for this climate and this building use.
Uses that do not need drinking-water quality should be separated early. Irrigation, toilet flushing and process water often drive the balance more than the kitchen tap.
Some on-site treatment or reuse options are closely regulated in Australia. Part of the advice is saying where a strategy is straightforward, where it needs an authority pathway, and where it may not be available on this site. That is a discussion with the hydraulics consultant and the relevant authority, not a nationwide rule we invent here.
Roof area, tank volume, treatment plant-room space and landscape irrigation have to be found in the architecture while the plan can still change.

A tank is not a Petal strategy on its own. Catchment, storage, connected demand and the unused water's destination have to add up.
Uses that do not need it should be separated early. Irrigation, toilet flushing and process water often drive the balance more than the kitchen tap.
Some options are closely regulated in Australia. We work out with the hydraulics consultant and the relevant authority where a strategy is straightforward, needs a pathway, or may not be available.
Send the LBC ambition and site information.
We test the water balance against the site and the registered program version.
You receive a briefing, a water-balance diagram for discussion, and a documentation map. Timeframes are confirmed at quote.
