ATHENA Impact Estimator for Buildings

The Impact Estimator is a standalone program that allows users to model their own custom assembly and envelope configurations, allowing them the flexibility to more accurately model proposed designs and existing buildings. The user needs some technical knowledge, but does not need to be a structural engineer or architect in order to model a building in Impact Estimator. Although not an energy simulation tool, the Impact Estimator allows the user to input energy simulation results to calculate their operating effects alongside their embodied effects. It is designed to evaluate whole buildings and assemblies based on internationally recognized life cycle assessment (LCA) methodology.
