The need for consistent and transparent common sustainability metrics  was stressed at a specialized, technical conference organized by the Sustainable Building Alliance (SB Alliance) initiative.
SB Alliance is a non-profit, non-partisan international coalition of standard setting organizations, national building research centers, and key property industry and construction sector stakeholders that is intended to accelerate the international adoption of Sustainable Building (SB) practices through the promotion of shared methods of building performance assessment and rating.
