Presentation given by Elrond Burrell, Associate at Architype Ltd, at NBSLive 2013 http://www.thenbs.com/NBS-Live/index.asp in the BIM room.

1. Delivering!
Radical!
Low Energy!
Performance!
with BIM

3. We design
Life Enhancing
Sustainable Architecture That Works

4. Overview
BIM
Passivhaus
BIM + Passivhaus
BIM 4 Passivhaus
Outcomes

5. BIM
“Building Information Modeling (BIM) is
the process of generating and managing
information about a built asset over its
whole life.”
Cabinet Office 2012

6. BIM
A quality assurance delivery strategy to
provide the right information at the right
point in the process

7. Passivhaus
“…the world’s leading standard in
energy efficient design”
Optimal Comfort (ISO 7730)
Minimum Energy

8. PHPP
“simplified models, precise data”
Accurate
Open
Parametric
Instant

9. Passivhaus
A quality assurance standard that ensure
that the right information is used at the
right point in the process to deliver
reliable energy performance & comfort.

10. BIM + Passivhaus

Model and test
- Not box ticking
- Not sexy graphics
- Not on site

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

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

13. Design Coordination

14. Design Coordination

15. Thermal Continuity

16. Heat Loss Envelope

17. Accurate Live Numerical
Data
Treated Floor Area (TFA)
Actual Volumes
Ventilation Volumes
Heat Loss Areas
Window / Door Opening Areas

18. Areas and Volumes

19. Heat Loss Areas

20. Opening Areas

21. Outcomes
2 x 65kW Boilers for a 2200m2 School
25kW peak heat demand
= 5x oversized!
90% reduction in gas consumption

23. Fresh Indoor Air

24. “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

27. Conclusion
Use BIM to support the Passivhaus
design process
People design sustainable buildings not
software!
