Presentation Transcript

  1. Athena Impact Estimator • Helpful during design phase or for post-construction assessments • Type and magnitude of potential environmental effects • Help to make decisions based on tradeoffs

  2. Inputs • Material assemblies • Foundation • Walls & openings • Beams and columns • Roofs • Floors • Extra basic materials (XBM)

  3. Behind the Scenes • Takes inputs to generate materials’ inventory for the building (bill of materials) • References Athena LCI database (absolute values) • Energy • Air emissions • Water emissions • Land emissions • Resource use • Applies factors for TRACI impacts categories

  4. Outputs • Summary measures (TRACI impact categories) • Primary energy consumption (embodied energy) • Weighted raw resource use • Global warming potential • Acidification potential • Human health respiratory effects potential • Aquatic eutrophication potential • Ozone depletion potential • Photochemical smog potential • By life cycle stage or assembly groups • Manufacturing • Construction • Maintenance • End-of-life • Operating energy
