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.

    We used to look for coatings, adhesives, and sealants that contained no VOCs. Great for smog prevention, but IAQ and installer health are also important.
