If we are to drastically reduce carbon emissions and meet IPCC carbon reduction goals, architects need to be part of the solution. However, reducing embodied carbon takes a lot of time and knowledge: a reality that is a barrier for many small firms, practices with no overhead, and project schedules. Learn how to apply new tools and techniques to attack embodied carbon emissions early in project design, when the largest wins are achievable with Payette’s Kaleidoscope: Embodied Carbon Design Tool. This free web-based tool empowers designers to assess various building assemblies for embodied carbon impact. Whole building Life Cycle Assessments (LCAs) are useful to determine the overall embodied carbon impact for a project - however, most currently require a complex 3D model. Kaleidoscope does not require any model and can be used throughout early design and construction to make quicker, more informed decisions regarding LCA. Facade and interior materials are often chosen early in the design process, and the tool empowers designers to consider the LCA impact of their aesthetic choices. The session will utilize demonstrations to illustrate how to use the tool to reduce carbon emissions early in project design.
