The Living Building Challenge consists of seven performance
categories, or “Petals”: Place, Water, Energy, Health & Happiness,
Materials, Equity and Beauty. Petals are subdivided into a total of
twenty Imperatives, each of which focuses on a specific sphere
of influence. This compilation of Imperatives can be applied to
almost every conceivable building project, of any scale and any
location—be it a new building or an existing structure.

“Over the last twenty years, green building has grown to
become the most important and progressive trend in the
building industry. There have been huge steps forward in
the design, construction and operation of buildings, and yet
when compared with the rate of change that is required to
avoid the worst effects of climate change and other global
environmental challenges, our progress has been minute and
barely recordable.” @card

“The living building challenge is a philosophy, certification and advocacy tool for projects to move beyond merely being less bad and become truly regenerative”

This is what we must strive to achieve as a team! @card

renewable energy.
