3. DRIVERS TO CHANGES IN PART L
1989 Intergovernmental Panel on Climate Change
2009: European Templates for National Renewable Energy Action Plans (NREAPs)
1997 Kyoto Protocol adopted EU 15 -8% reduction 2012, - 20% 2020
2008: European Renewables Directive: 20% (2020)
2002: European Energy Performance of Building Directive
2005: European Energy End
Use Efficiency & Energy Services Directive
2004 : European Directive on Cogeneration

4. IRELANDS’ SUSTAINABILITY TRANSITION
2002: SEAI established
2007: National Climate Change Strategy
2007: White Paper “Delivering a Sustainable Energy Future for Ireland”
2007: Building Energy Rating
2008: Building Regulations Revised
2009: Developing the Green Economy in Ireland
2010: Draft NREAP published
2011: TGD L (Dwellings)

7. The challenge in implementing TGD 2011
Whole energy & carbon performance 60% improvement on 2005 standards
Compliance is onerous
Requires a completely different approach
Using backstop insulation values will no longer ensure compliance – need to go to Passive House standards?
Rigorous approach to thermal bridging
Understanding of air tightness & fabric junctions
Impact on construction methodologies
MPCs will need to be calculated at an early stage

8. Risks & Precautions Increased Insulation & Energy Conservation risks
Changes in construction – end of the cavity wall?
Rain penetration – algae growth/ lack of drying out & frost action
Condensation
Air permeability

9. At what point does cavity wall construction become impractical ?
The Cavity Wall Debate
300 mm
At what point does cavity wall construction become impractical ?

10. Alternatives to Traditional Construction
Increased cavity widths
Internal insulation
External insulation
Alternative masonry techniques
MMC approaches
Buildable & Practical Approaches – construction types will become more varied until the market settles on the most cost effective and practical approach

11. What direction should education in Architectural Technology take?
Part L will be constantly evolving, our response should be to look at the BIG picture

12. Ventilation losses + heat losses = heating requirement
Cannot fully understand one without the other - All of equal relevance
Basis of Part L, DEAP and Passive House Strategy… this is nothing new
Ventilation losses heat losses = heating requirement
Reduce space heating by …….
… reducing ventilation losses and heat losses

13. How does this translate into detailing?

14. Traditional Structural Integrity
All three on equal footing… could add more, like aesthetic, condensation etc?

15. Traditional Structural Integrity Water tightness
All three on equal footing… could add more, like aesthetic, condensation etc?

16. Traditional Structural Integrity Water tightness U-value
and basic thermal bridging
All three on equal footing… could add more, like aesthetic, condensation etc?

17. Current situation…? More onerous U-values and
Detailed thermal bridging
Detailed Interstitial Condensation
Structural Integrity
Water tightness
Air-tightness
and
Ventilation strategy
Space heating
and
Energy requirements
Renewable energy options
On equal footing…???

18. Do Architectural Technology students learn these all at the same time?

19. Are first year AT students equipped to deal with all of this?

20. Knowledge Experience and Time…
One could argue that a higher-order of understanding is required for some of these elements, with students allowed to learn through
Knowledge
Experience
and Time…

21. …to fully realise innovative Architectural detailing design solutions by Level 8 and 9

22. What will make our students employable?

23. By training student to be proficient in detailing up to CURRENT Building Regulation Standards, they join others of equal ability …

24. However, to not only be employable, but to generate employment in specialist areas...

25. ... To have key roles in consultation and research ...

26. ... to pioneer our knowledge economy ...

27. We should aim BEYOND future Part L standards, passive house and ener-phit, zero carbon, zero energy and positive energy building standards now and give our students the tools to be able to do just this …

28. How is this mapped onto an educational level and building-types studied?

29. Level 6
Year 01
Domestic
Level 6
Year 02
Framed, small commercial /industrial
Level 7
Year 03

30. Structural Integrity
Water tightness
More onerous U-values
and
Detailed thermal bridging

and
Energy requirements
Renewable energy options
… work in progress to map them…!
