Life Enhancing"
Genuinely Sustainable Architecture

5. Overview
1. The Context of BIM
2. Getting into BIM
3. BIM & Passivhaus

6. 1. The Context of BIM

8. BIM isn’t new!

9. Why now?
1. Software & Hardware capabilities
3d Modeling
Structured Information
Digital Collaboration

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

11. Why UK Gov + BIM?

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”

13. UK Gov Strategy

14. Mandated BIM

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

17. UK Gov Purpose
20% reduction in capital costs
20% reduction in CO2 emissions
+ reliable outcomes
+ predictable building (asset) performance

18. UK Gov BIM + GSL

19. BIM standards

20. BIM Protocols

21. 2. Getting into BIM

22. Observing Pre-BIM
Duplicate working
Designing in 3d, documenting in 2d
CAD standards not always enforced

23. Proposing BIM
Quick “proving exercise”
Demonstration of key benefits
Overcoming doubts & resistance to change

24. BIM Pilot Project Rules
Small / Medium single storey
Short duration
Bland, not too creative
Plan for pulling back to CAD

25. BIM Pilot Project Rules

26. Benefits
Carefully manages risk, minimises potential
losses
Facilitate a gradual transition / learning
Allows for easy comparison between projects

27. Risks
No benefits of BIM gained
No memorable experiences
No mindset-shift

28. Following the Rules:
“BIM is a RISK to be managed”

29. OR… No Rules?
Large project, multi-storey
Long duration
Highly creative, challenging design
Commit to BIM, no plan to pull back to CAD

30. Start!
With a project that matters to your business

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

33. No Rules
“BIM is an OPPORTUNITY to be realised”

34. BIM vs CAD

36. Our Pilot Project

37. The Willows
£17m / 6500sqm Lifelong learning campus
Multiple clients
Complex geometry
6 Phases, 10 Mineshafts

39. Ensuring Success
Training / Support
Project based bespoke training
At desk training
In-house expert (guess who?!)

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

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!)

45. Bonus Results
Unexpected use of the model
Staff exceeding expectations
Spread of BIM skills

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”

51. State of Mind vs Skill

52. State of Mind vs Skill

53. State of Mind vs Skill

54. Beyond the first project
Internal uptake
External demand
The wider design team / Level 2 BIM

55. Bidding

56. LOD

57. Designing

58. Communicating

60. Almost Level 2

63. 3. BIM & Passivhaus

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.

67. BIM + Passivhaus
Process

Model and test
Not box ticking
Not sexy graphics

68. BIM 4 Passivhaus
Simple + Useful + Productive
1. Visual interrogation
2. Accurate Live Numerical Data

69. Visual Interrogation
Design coordination / integration
Thermal Continuity
Heat Loss Envelope

70. Design Coordination

71. Design Coordination

72. Thermal Continuity

73. Thermal Bridges

74. Heat Loss Envelope

75. Accurate Live Data
Treated Floor Area (TFA)
Actual Volumes
Ventilation Volumes

76. Areas and Volumes

77. Heat Loss Areas

78. Opening Areas

79. What does this deliver?
2 x 65kW Boilers for a 2200m2 School
25kW peak heat demand
= 5x oversized!
90% reduction in gas consumption

81. Breathe easy!

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

are useful.”
