Petals are performance categories in the Living Building Challenge. This project documented three petals: Materials, Place, and Equity. Within each petal is a set of imperatives, requirements that must be met to achieve the petal. The imperatives and strategies employed are described below.
The Materials Petal is a stringent set of criteria aimed to provide better health for building occupants plus everyone that deals with the project materials during their life-cycle. It also encourages teams to find local and salvaged materials to reduce the embodied carbon of the project.
The Place Petal helps to ensure a sustainable future for cities, suburbs, and rural areas. It focuses on smart growth and addresses the ecological impacts of developing land.
