  2. 2. We design Life Enhancing Genuinely Sustainable Architecture
  3. 3. “Essentially, all models are wrong, but some are useful.” – George E. P. Box
  4. 4. “Software doesn’t design sustainable buildings, people do.” – Elrond Burrell
  5. 5. Caveats A UK based Architect’s perspective BIM tools our teams use: – Vasari, Revit, Ecotect, IES, PHPP Sustainable Design is a HUGE topic
  6. 6. Overview 1. Sustainable Design? 2. BIM for SD decision making 3. BIM for SD compliance (BREEAM) 4. BIM for SD performance (Passivhaus)
  7. 7. 1. Sustainable Design? Brundtland Commission - Sustainable development? • What the earth can sustain Sustain & nourish people and planet? • ‘Sustainable’ and delightful, healthy, affordable . . .

  47. 47. Semi-native Visual check / evidence within model Generate data for credits Generate data to export for analysis
  48. 48. Visual Check / Evidence Man 7 Shared Facilities One credit may be awarded where evidence provided demonstrates that shared facilities have been provided as a consequence of consultation feedback. Two credits may be awarded where, in addition to the above, evidence provided demonstrates that these facilities can be accessed without compromising the safety and security of the building and its occupants.
  49. 49. Generate data for credits Mat 1 Materials Specification – Major Building Elements Up to six credits may be awarded where evidence provided demonstrates that the major building elements specified have either an ‘A+, A or B rating’, as defined in the Green Guide to Specification.
  50. 50. Generate data for analysis Hea 1 Daylighting One credit may be awarded where evidence demonstrates that at least 80% of floor area in each occupied space complies with the following: • An average daylight factor of at least 2%; AND • A uniformity ratio of at least 0.4 or a minimum point daylight factor of at least 0.8% (spaces with glazed roofs, such as atria, must achieve a uniformity ratio of at least 0.7 or a minimum point daylight factor of at least 1.4%).
