Slides from a guest lecture presented at London South Bank University, 07 May 2014.
Part 1 - The Wider Context of BIM including UK Government Poilcy
Part 2 - Architype's journey into BIM
Part 3 - Using BIM for Passivhaus Design
12. 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”
15. What is 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.
17. UK Gov Purpose
20% reduction in capital costs
20% reduction in CO2 emissions
+ reliable outcomes
+ predictable building (asset) performance
31. Benefits
Maximises all available benefits of BIM
Longer duration allows for learning & mistakes
Exciting, interesting, engaging… the BIM
mindset sticks
32. Risks
Much more at stake that could go wrong
High level of training & support needed
Takes longer to see the results, harder to
compare
39. Ensuring Success
Training / Support
Project based bespoke training
At desk training
In-house expert (guess who?!)
40.
41. Ensure Success
The Team
Tasks to suit abilities (not roles)
Focus on LOD for outputs & outcomes
Involve whole team in the real-world project
42.
43. Results
Stage D output in 4 weeks, reduced Stage E-F team
500+ drawing sheets,1355 unique views directly
from the digital model
Massive productivity gain
Site RFI turn around in hours (not days!)
46. 5 Stages of BIM
1. Initial Excitement
“Wow, Look what I can do with this thing!”
47. 5 Stages of BIM
2. First Bump
“Why won’t it do what I want?
…It was easy in CAD!”
48. 5 Stages of BIM
3. Creamy Middle
“Things are going smoothly now”
49. 5 Stages of BIM
4. WTF!?
“Component Creation eats you up and spits
you out”
50. 5 Stages of BIM
5. Enlightenment
“Things really click. You understand why things
happen in the model, how to control them and
how to avoid problems”
64. 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
65. PHPP: BIM or BEM?
“simplified models, precise data”
Accurate
Open
Parametric
Instant
66. 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.
82. “We feel that our children are more alert and
attentive in lessons due to the amount of
daylight in classrooms and the fresh air
throughout the school ... learning has been
enhanced”
Sara Morris, Head Teacher
