ATHENA® Impact Estimator for Buildings

Architects, engineers and researchers can get life cycle assessment (LCA) answers about conceptual designs of new buildings or renovations to existing buildings from the Athena Institute's Impact Estimator for Buildings. The Estimator lets you assess the environmental implications of industrial, institutional, office, and both multi-unit and single family residential designs. Where relevant, it also distinguishes between owner-occupied and rental facilities. The Estimator puts the environment on an equal footing with other more traditional design criteria at the conceptual design stage of a building project.
