Living Building Challenge 4.0

Imperative Overview

INTENT

The intent of this Imperative is to foster local communities and businesses, while minimizing transportation impacts.

REQUIREMENTS

The project must incorporate place-based solutions and contribute to the expansion of a regional economy rooted in sustainable practices, products, and services.

Manufacturer location for materials must adhere to the following restrictions:

  • 20% or more of the materials construction budget must come from within 500 kilometers (km) of the construction site.
  • 30% of the total materials construction budget must come from within 1000 km of the construction site or closer.
  • An additional 25% of the materials construction budget must come from within 5000 km of the construction site.
  • The remaining 25% of materials may be sourced from any location.

CHANGES FROM LBC 3.1 TO 4.0

In order to encourage the sharing of expertise across project teams, the requirement that Consultants come from within 2,500 kilometers of the project location is no longer a requirement in LBC 4.0.
