Abstract: The climate crisis raises the question whether energy targets of building regulations should be more holistic by considering also embodied energy of materials. While focusing on thermal and daylight user comfort in order to reach ambitious energy and greenhouse gas targets simulation tools must efficiently and more holistically guide the planning process starting in the early design phases when the major decisions are made. The sensitivity of various parameters also needs to be studied to find the most appropriate solution. In this case-study embodied energy of materials based on the Ökobaudat are calculated for a low-tech office building using Grasshopper and Rhinoceros. In parallel, dynamic thermal building and system simulation are applied with TRNSYS 18 and Radiance in a parametric multizone building model. Both variants are put into one context with various lifespans. In total up to 100 years are analyzed to indicate the highest energy consumers for optimization.
