The Living Building Challenge (LBC) is widely considered the most stringent green building standard in the world. LBC, run by the International Living Future Institute, attempts to emulate a flower by encouraging net-zero or net-positive impact on virtually everything the built environment touches. Its requirements are categorized under seven petals:

  • Place

  • Water

  • Energy

  • Health

  • Materials

  • Equity

  • Beauty

Through detailed “imperatives,” LBC leaves little wiggle room. Everything is a prerequisite, unlike in LEED, where project teams can choose among credits.

Here we have collected strategies, case studies, and expert commentary on how to achieve LBC certification in the real world.
