WBLCA Worksheet

The WBLCA (Whole Building Life Cycle Assessment) Worksheet provides guidance on conducting comprehensive life cycle assessments for entire building systems, differentiating from assessments focused on individual products or components. It helps teams consider functional equivalency when comparing alternative design schemes and materials, ensuring all options include the full bill of materials necessary to meet equivalent performance criteria. The worksheet addresses scope considerations including structural elements, building envelope, finishes, and assembly components required for acceptable performance.
