The location of the building on the site, its basic form and orientation, its internal layout and external materials selection, its fenestration - all of these factors are set very early on in the design process and often with no analysis data to support the decisions. 3) Sensitivity analysis of impact of design change can be conducted using the combination of Ecotect and BIM model.BIM and Autodesk Ecotect (1-2-3 Revit Tutorial) 30 Nov, 2008 By: AIA, Rick Rundell How BIM and Autodesk Ecotect help architects understand their conceptual building design's performance.Įditor's note: This tutorial courtesy of Autodesk.įor most building projects, decisions made in the first few weeks of the design end up having the greatest impact on a building's performance. 2) Energy consumption in the operating stage dominates the lifecycle energy consumption of the building. The data entry workload for whole building LCA can be reduced significantly. The conclusions of the study are: 1) The combination of Ecotect and BIM model provides a convenient tool to conduct whole building LCA through the easier data flow from the BIM model to Ecotect. Preliminary results indicated that whole building life cycle performance is affected by several design parameters, with different degree of sensitivity. Sensitivity analysis was performed by changing several alternative parameters, to identify which parameter has more impacts on building performance. The study compared life cycle performance, i.e., CO 2 emissions and energy consumptions, among different design configurations, as well as their distributions in the stages of the building’s life time.
Life cycle energy consumption and CO 2 emission of a university building in the Midwest was calculated using Autodesk® Ecotect and BIM model. The research question addressed was how life cycle performance of a building was affected quantitatively by design configurations. The main objective of this study is to evaluate the potential of utilizing building information model (BIM) to perform whole building Life Cycle Analysis (LCA).
