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

Digital Collaboration

8. Why now?
2. Digital / Social Media ‘Tsunami’
Digital everything
Social everything
… will the construction industry catch up?

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. DSM example

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. 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

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.
