Henry rock evans max fordham lcbb 160517 performance versus regulation

  1. 1. SUSTAINABILITY IN PRACTICE LOW CARBON SOUTH WEST BUSINESS BREAKFAST MAY 2017
  2. 2. WHOLE BUILDING ENGINEERS We’re engineers. We work closely with architects to design buildings that really work. This means we’re concerned with the big picture and the small detail of buildings.
  3. 3. MAX FORDHAM Founded 1966 Offices in London, Edinburgh, Cambridge, Manchester and Bristol 215 staff, 166 engineers One of the largest independent practices in the county International award winning presence Over 4000 projects
  4. 4. OUR APPROACH WHOLE BUILDING DESIGN We engineer air, light, sound and energy BUILDING SERVICES & LOW ENERGY DESIGN BUILDING ACOUSTICS SUSTAINABILITY BUILDING PHYSICS RENEWABLE ENERGY ENVELOPE PERFORMANCE
  5. 5. BUILDING SUSTAINABLY “How can we design (and build) a building that is an exemplar in efficiency and sustainability?”
  6. 6. COMMUNICATING SUSTAINABILITY O Complex projects, not easy to ‘categorize’ O Client aspirations and passion O How to define sustainability in these circumstances? O Funding requirements O Planning sensitivities O Multi-headed client O Many stakeholders
  7. 7. ACCREDITATION
  8. 8. CERTIFICATION– BENEFITS AND LIMITATIONS O Pros O Externally certified rigorous process – credible O Required (for planning/funding) O Well understood O Comparable O Expected O Cons O Time and paperwork intensive O Can potentially incentivise perverse choices O Could reward design elements potentially considered unimportant O May not deal with some issues successfully
  9. 9. CERTIFICATION OPTIONS Scheme Owned/ operated by Origin Limitations BREEAM BRE UK As built performance; Sustainable operation
  10. 10. BREEAM LIMITATIONS Not dealt with successfully (or at all): O As built performance O Energy O Water O Changing conditions / operation O Sustainable operation O Operational waste O Sustainable procurement and consumables O Education
  11. 11. CERTIFICATION OPTIONS Scheme Owned/ operated by Origin Limitations BREEAM BRE UK As built performance; Sustainable operation; Overly prescriptive and inflexible LEED USGBC US Costly; couched in monetary savings not carbon reduction terms; fiscal contributions for credits Living Building Challenge Living Future Institute Canada Not widely known/used WELL standard IWBI US Focus on health, removes personal choice?, developed for US market Sentinel Haus Sentinel Haus Institute Germany One topic focused- air quality Passivhaus Passivhaus Institute Germany One topic focused- energy One Planet Living Bioregional UK Descriptive rather than technical targets, very flexible
  12. 12. ALTERNATIVES TO CERTIFICATION O Max Fordham Sustainability Matrix O Soft Landings O Setting Energy Budgets
  13. 13. THE SUSTAINABILITY MATRIX
  14. 14. FRAMING THE CONVERSATION What is important?
  15. 15. FRAMING THE CONVERSATION Minimum Standard Best Practice Innovative Pioneering What is the range of possibilities?
  16. 16. SETTING THE ASPIRATIONS Materials Biodiversity Water-use Climate change adaptation In-use energy Daylighting Smart Homes Minimum Standard Best Practice Innovative Pioneering
  17. 17. THE HEELIS, NATIONAL TRUST HQ
  18. 18. THE HEELIS, NATIONAL TRUST HQ
  19. 19. Sustainability Overview √ √ √ √ √ √ √ √
  20. 20. THE PERFORMANCE GAP O How do you make all this happen in practice? O How do you avoid issues due to: O Erosion of ideals during design / VE O Quality of construction O Quality / completeness of commissioning O Unexpected building usage?
  21. 21. KEYNSHAM CIVIC CENTRE CLIENTS BRIEF: Ultimately, the success of the building will be judged on its operational energy use and resultant carbon emissions. Therefore, the current aspiration is that the development should achieve a DEC rating of A by the end of the second full year of operation. © Daniel Hopkinson / AHR 2014
  22. 22. KEYNSHAM CIVIC CENTRE MATRIX
  23. 23. Procuring Soft Landings O Low energy design- the easy bit! O The Sustainability Matrix O Energy budget O Energy risk management O Use lessons learnt from past projects O Manage VE O Embed in contract O Aftercare programme O Lessons learnt again…… OUR APPROACH
  24. 24. LOW ENERGY DESIGN (the easy bit!) ACTUAL OPERATIONAL ENERGY ACHIEVING A DEC A
  25. 25. ENERGY RISK REGISTER
  26. 26. Energy use category Annual energy budget Within contractor’s control Outside contractor’s control Assumptions: Lighting Lux levels Power density Controls as specified Task lights Hours of operation External illuminance 31,000 kWh 16,000 kgCO2 EMBEDDING INTO THE CONTRACT
  27. 27. AFTERCARE: MONITORING & VERIFICATION
  28. 28. KEYNSHAM ENERGY DEC
  29. 29. KEYNSHAM LIGHTING ENERGY
  30. 30. SUMMARY O Understand what sustainability means in each case. O Set appropriate targets – understand what the client wants the building for: helping a client get the building that they actually need is part of sustainability! O Make this happen in practice.
  31. 31. THANK YOU SUSTAINABILITY IN PRACTICE Henry Rock-Evans 16/05/17
