Steve Charter, Green Gauge Trust - "Introduction to Sustainable Construction: A Stategic Overview of Where We Are Now"

  1. 1. Introduction to Sustainable Construction: A Strategic Overview of Where We Are Now<br />Steve Charter Training Development Manager Green Gauge Trust<br />
  2. 2. Why be interested in sustainable buildings?<br />Buildings = 40+% CO2 emissions<br />2016 and 2019 ‘zero carbon’ standards<br />It’s a big market<br />Legal targets:<br /><ul><li> 26% domestic CO2 reduction by by 2020
  3. 3. 80% CO2 reduction by 2050</li></ul>80% of homes in 2050 have already been built<br />26 millionexisting homes to deal with now<br />27% of current UK carbon emissions<br />
  4. 4. UK - where are we heading? <br />Standards for New Non-Domestic Buildings?<br />Demand for Sust new build skills ?<br />Standards for New Build Housing?<br />Demand for retrofit <br />skills ?<br />Standards for the Existing Stock?<br />2010 Building Regs Part L standards<br />Green Deal<br />Starts<br />EcoSchools<br />Responses to CRC kicking in<br />
  5. 5. Mainstream Sustainable Building Standards:<br />GreenStar (Australia)<br />LEED (USA)<br />Code for Sustainable Homes (UK)<br />Code for Sustainable Buildings – (UK, impending)<br />BREEAM (UK)<br />Less Known Standards:<br />AECB Gold & Silver Standards (UK)<br />Low Energy Building Standards:<br />Passivhaus (Germany; Austria)<br />Minergie (Switzerland)<br />Super-E (Canada)<br />Part L (UK)<br />Question: <br />Why are there less low energy standards?<br />Sustainable Building Standards<br />Green Stripes CPD course: <br />Understanding sustainable building standards, regulations and <br />methodologies<br />
  6. 6. Trend: ‘Zero Carbon’ definition<br />Recommended revised definition of ‘Zero Carbon’<br /> and Fabric Efficiency Standards = kWh/m2/yr<br /><ul><li>39 kWh/m2/yr - flats & mid-terrace;
  7. 7. 46 kWh/m2/yr - semis / end-of-terrace & detached;
  8. 8. Covering Space heating & cooling energy demand</li></ul>NOTE: Passivhaus as a global benchmark: why?<br /><ul><li>15kWh/m2/yr for cost and energy efficiency
  9. 9. Based on building physics; 20 years of experience;
  10. 10. Methodology based on accurate predictions of performance – not on notional buildings (SAP);</li></ul>Do you understand yet why we think sustainable building always costs more in the UK?<br />
  11. 11. The future for buildings and skills<br /><ul><li>Buildings built or refurbished to absolute energy & carbon targets
  12. 12. i.e. kwh/m2/year and kgCO2 /m2/year
  13. 13. Delivered by teams with skills accreditation</li></ul>Because this gives assurance of: <br />design and build quality <br />energy performance and CO2 outcomes<br />
  14. 14. Predictable Trends<br />From 2013 work in housing and buildings sector will mean:<br /><ul><li>sustainable buildings are the normal objective
  15. 15. sustainable products and technologies are the norm
  16. 16. sustainable building skills are the norm
  17. 17. careers in sustainable building are a good choice</li></ul>Parity Projects Demo House<br />Carshalton<br />
  18. 18. Defining Sustainable Building<br />People define sustainable building in different ways<br />No definite ‘A + B + C = D’ definition exists<br />But, we know sustainable building is about:<br />Design + Construction + Use + Demolition /Re-Use<br />Significantly Reducing ‘Whole Life’ Negative Impacts<br />Consciously Increasing ‘Whole Life’ Benefits<br />i.e. Sustainable Building = Whole-life x <br />minimised negative impacts x maximised positive benefits<br />
  19. 19. 3. Generate Income<br /><ul><li> renewable energy
  20. 20. training?</li></ul>Education /Research<br /><ul><li> yourself
  21. 21. your company
  22. 22. others</li></ul>2. Save Money<br /><ul><li> Minimum energy </li></ul>& utility bills<br />Shelter & <br />Home<br />5. Inspiration / Creativity<br /><ul><li> yourself
  23. 23. your company
  24. 24. others</li></ul>7. Enhance Ecology<br />& Biodiversity<br />6. Healthy<br /><ul><li> zero toxins
  25. 25. natural lighting & ventilation</li></ul>By 2025 this approach to sustainable buildings will be the norm, not the exception<br />
  26. 26. The low carbon future<br />It will be understood that well designed, well built or retrofitted low energy low carbon buildings =<br />warm in winter<br />cool in summer<br />excellent indoor air quality<br />= sustainable<br />very low running costs<br />Centre for Disability Studies: Passivhaus certified and BREEAM Outstanding<br />… a shift in understanding, like going from a privy to a house with indoor plumbing!<br />
  27. 27. Where are we now? A UK reality check<br />11<br />Stamford Brook Research (Leeds Met Uni)<br /><ul><li>actual build quality very often does not even reach current Building Regs energy performance;</li></ul>CarbonBuzz (RIBA & CIBSE)<br /><ul><li>Actual energy use rarely achieves predicted use (i.e. is higher)</li></ul>BSF ‘Green Schools’ (Usable Buildings Trust)<br /><ul><li>not designed to be low energy buildings;</li></ul>BREEAM & ‘Zero Carbon’ Definitions<br /><ul><li>being improved to be more energy-intelligent forms – i.e. BREEAM ‘Excellent’ does not = Low Energy Building
  28. 28. BREEAM ‘Outstanding’ because ‘Excellent’ isn’t good enough </li></ul>But ... for the Germans and Austrians it’s all normal, and easy!<br />
  29. 29. Reality Check – where are we now?<br />12<br />
  30. 30.
  31. 31. Airtightness Skills<br />
  32. 32.
  33. 33. Other Important Skills<br />Ecology and biodiversity<br />Healthy buildings<br />People skills: e.g. team and client communication<br />Modelling skills: particularly re energy use<br />Energy monitoring & efficient ICT systems<br /><ul><li>building monitoring and management systems
  34. 34. Green ICT – ICT is a large energy user & secondary heat producer</li></ul>Business & commercial skills: specialist sales, finance & marketing, etc<br />
  35. 35.
  36. 36.
  37. 37. Everyone Needs Education<br />
  38. 38. Overview of the Green Deal<br />A major new policy initiative to cut carbon emissions from existing UK housing and buildings<br /><ul><li> finance packages for low carbon retrofit + some financial incentives (funded by Energy Co’s)
  39. 39. paid for by Green Deal charge on your energy bill
  40. 40. ‘Green Deal Measures’ must meet the ‘golden rule’
  41. 41. revisions to RDSAP, SAP & EPC + linked to actual performance
  42. 42. Accredited Green Deal Advisors and Installers
  43. 43. Qualifications, training, apprenticeships
  44. 44. Housing + SME business premises</li></li></ul><li>Housing retrofit market<br />To achieve an 80% CO2 reduction by 2050<br /><ul><li>600,000+ housing retrofits per year =
  45. 45. 2,500 retrofits /working day
  46. 46. 333 completions /working hour
  47. 47. 5.5 completions a minute!</li></ul>SE region = 3.66mn dwellings<br />= 45 retrofits / working hr = £1mn / wking hr<br />For Radian Housing = 400 homes / year = £8mn / yr<br /><ul><li>= 1.5 completions / working day
  48. 48. = £320,000,000 spend by 2050 at current costs</li></ul>Paul Ciniglio, Sustainability Manager, Radian Housing<br />
  49. 49. SE Housing retrofit market<br />To achieve an 80% CO2 reduction by 2050<br /><ul><li>3.66 million dwellings in Southeast</li></ul>75% owner occupied<br />11% private rented<br />8% Housing Assoc rented<br />6% Local Authority rented<br />Assume 90%+ retrofitted by 2050<br />= 86,700 retrofits /year = 350 completions /working day<br />At say £20,000 per retrofit:<br />= £1.73 billion retrofit spend in SE per year<br /> = £1.3 billion+ p.a. owner occupied spend per year<br />+ Commercial retrofit spend – Green Deal and in response to CRC<br />
  50. 50. Skills Needs in Housing Retrofit<br />To achieve an 80% reduction by 2050<br /> over 2,500 retrofits completions/working day; <br />UK Skills Needs = 680,000 x (1/12) x 6 = 340,000?<br />South East Skills Needs? <br />80,700 retrofits p.a. x (1/12) x 6 = <br />Over 40,000 Permanent NW retrofit trade workforce?<br />Plus professional, technical and management<br />Plus a lot of trainers needed!<br />
  51. 51. Why accredited skills are needed<br />The risk of failure v’s success in low energy sustainable building outcomes relates directly to knowledge and skills<br />Assume 90% knowledge and experience re energy issues = <br />90% chance of success in desired outcomes for:<br /><ul><li>client
  52. 52. designer / design consultant
  53. 53. project management
  54. 54. site management
  55. 55. site skills</li></ul>The risk of failure is cumulative: <br />i.e. 0.9 x 0.9 x 0.9 x 0.9 x 0.9 = 0.59<br /> Less than 6 in 10 chance of achieving desired outcome!<br />
  56. 56. Expertise & competence minimise risk<br />1.2 x 0.9 x 0.9 x 1.2 x 0.9<br />= 1.05<br />Team has 105% of necessary<br />knowledge<br />i.e. risk of failure is avoided<br />For example:<br />% of low energy building knowledge / skills needed to get their job right in the whole building process<br />
  57. 57. The positive message is ...<br />You can create low energy sustainable buildings in cost effective, efficient and reliable ways when you have the skills and knowledge to do so. <br /> This is so for existing buildings or new build<br /> IMPORTANT - mainly this involves: <br />improving or refining existing skills <br />adding new knowledge. <br />Jubilee Wharf, Penryn<br />
  58. 58. Some major challenges<br /> Currently a distinct lack of:<br />formally accredited courses on sustainable building issues;<br />low-energy content in core building-related qualifications e.g. BTECs, NVQs, etc.<br />trainers with real experience / competence in low energy sustainable building.<br />technical understanding within Awarding Organisations and SSC’s<br />
  59. 59. Sustainable building skills strategy<br />Clarify key knowledge & skills issues<br />Understand business / economic implications of: a) having those skills; b) not having those skills.<br />Work out individual & company skills needs & skills gaps<br />Put in place:<br />Knowledge & skills plan<br />Implement quality training system: including quality trainers, progression routes, etc<br />Complex junction details<br />Photo source: The Passivhaus Diaries, Bill Butcher of Green Building Company with Building Magazine<br />
