Dive Brief:

• The Living Building Challenge is often thought of as the toughest standard to meet in building green, but the organization that directs it, the International Living Future Institute, has now revised the rules.
• Challenge 3.0 has both refinements to earlier requirements and some new pieces.
• Among the changes are more emphasis on designing buildings to be resilient and more requirements for transparency about the materials to be used.

Dive Insight:

The Challenge was introduced in 2006, and the institute says almost 200 buildings have been registered for it. There are now completed Living Buildings, so it can be done. The institute says the new version is based on feedback from teams trying to build buildings that can make the grade.
