Transparency is the foundation for making informed decisions about the products we specify. The AEC industry is familiar with sustainability goals related to energy efficiency, but holistic discussions related to material goals across the entire team are still rare. Large strides have been made in interior product disclosure, but much less so for building envelope, MEP  and lighting systems. Without transparency our ability to quantitatively convey the magnitude of decisions made across the project team, and track progress as the design progresses, is limited. This panel will highlight the importance of product disclosure so a meaningful building LCA can be conducted, and the health and wellbeing impacts can be evaluated. Target areas for each discipline will be given as a way to focus discussion for goal setting and project kick-off meetings, and resources related to material transparency will be shared.
