Considerations & Worksheet for Structural WBLCA of Mass Timber Buildings

The design community has embraced the use of whole building life cycle assessment (WBLCA) as a means to quantify, and sometimes compare, the environmental impacts of buildings. While this momentum is exciting, detailed standards for a unified approach to WBLCAs are still in development, leaving designers without clear direction during the assessment process.

This document seeks to outline requirements pertaining to life cycle assessment (LCA) found in international standards, and provide guidance on how WBLCAs for mass timber buildings are performed using commercially available LCA tools.
