Building Information Modelling (BIM) is rapidly becoming the industry standard in building design globally. The UK government has announced that all centrally procured constructions projects need to use BIM by 2016 and expect this to reduce capital cost and the carbon burden from the construction and operation of the built environment by 20%. In Taiwan, the Head of the Construction and Planning Agency (CPA) announce that Taiwan government will support BIM development in public policy.

Architype are leaders in the the field of Sustainable / Green Architecture and are earlier adopters of BIM in their green design processes, particularly with regard to delivering radical reductions in energy consumption & carbon emissions.

Elrond Burrell, Associate at Architype, was invited to present a UK perspective on Green BIM at the National Taiwan University in Taipei on 13 February 2014. The BIM meeting was hosted by Prof. Shang-Hsien (Patrick) Hsieh and held in the Civil Engineering Research Building

Architype - Green BIM UK Perspective, NTU Taipei, 13 February 2014

  1. 1. Green BIM 13 February 2014, National Taiwan University, Taipei UK perspective
  2. 2. Elrond Burrell 趙晨瀚 Associate, Architype Ltd elrond.burrell@architype.co.uk
  3. 3. We design Life Enhancing" Genuinely Sustainable Architecture
  4. 4. Overview 1. The Rise of BIM 2. UK Government + BIM 3. UK Green BIM 4. Architype Green BIM
  5. 5. 1. The Rise of BIM
  6. 6. BIM isn’t new!
  7. 7. Why now? 1. Software & Hardware capabilities 3d Modeling Structured Information Digital Collaboration
  8. 8. Why now? 2. Digital / Social Media ‘Tsunami’ Digital everything Social everything … will the construction industry catch up?
  9. 9. 2. UK Gov + BIM
  10. 10. EU Directive Energy Performance of Buildings Buildings consume 40% of energy in EU By 2018 All new public buildings “Nearly Zero-Energy” By 2020 All new buildings “Nearly Zero-Energy”
  11. 11. EU Directive
  12. 12. UK Gov Strategy
  13. 13. UK Gov Strategy
  14. 14. UK Gov Purpose 20% reduction in capital costs 20% reduction in CO2 emissions + reliable outcomes + predictable building (asset) performance
  15. 15. UK Gov BIM “Building Information Modeling (BIM) is the process of generating and managing information about a built asset over its whole life.” Cabinet Office 2012
  16. 16. UK Gov BIM + GSL
  17. 17. BIM Protocols
  18. 18. 3. UK Green BIM Aspirations & Reality
  19. 19. Aspirations EPDs linked to Models Model based Green Rating compliance check The RegBIM project using IFC underway
  20. 20. Reality … ? Model based Embodied Carbon + Lifecycle Analysis Impact specification / database www.impactwba.com
  21. 21. Reality … ? Model linked Responsible Sourcing / Environmental Impact data NBS Create specification tool using Uniclass2 constructioncode.blogspot.co.uk
  22. 22. Reality REM - Rapid Energy Modeling Energy Carbon Day lighting Water Wind Thermal comfort Renewable energy generation Caveats Conceptual design guidance only Not an accurate prediction of actual performance
  23. 23. REM example 1 autodeskvasari.com
  24. 24. REM example 2 www.sefaira.com
  25. 25. Reality Dynamic Simulation Modeling Thermal modeling Overheating “Conservation of Fuel” regulations compliance Caveats Often not an accurate prediction of actual performance Interoperability issues often require re-modeling
  26. 26. DSM example
  27. 27. Reality Material waste reduction Accurate quantities from model Buildability issues resolved in model Caveats Is the model built for this purpose? How accurate? How resolved?
  28. 28. Reality Scan-to-BIM for Refurbishment ~80% of building stock exists already Accurate existing building model Early analysis of cost & carbon effective measures Risk / Cost reduction
  29. 29. Scan-to-BIM example
  30. 30. Scan-to-BIM example
  31. 31. Scan-to-BIM example
  32. 32. Reality In-Use Energy / CO2 emission reductions Accurate design data Accurate energy modeling tools Greatest climate change impact for new build Robust long term performance Significant cost savings / Best ROI Healthier buildings
  33. 33. 4. Architype Green BIM
  34. 34. Passivhaus Standard “…the world’s leading standard in energy efficient design” Rigorous performance standard Quality assurance Optimal comfort (ISO 7730) Minimal energy Climate specific – works anywhere
  35. 35. PHPP “simplified models, precise data” Accurate Open Parametric Instant
  36. 36. Data 4 QA Passivhaus can be seen as a quality assurance standard that ensure that the right information is used at the right point in the process to deliver reliable robust energy performance & comfort.
  37. 37. BIM + Passivhaus Process + Information + Model and test - Not box ticking - Not sexy graphics - Not on site
