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

    • Some major challenges
      Currently a distinct lack of:
      formally accredited courses on sustainable building issues;
      low-energy content in core building-related qualifications e.g. BTECs, NVQs, etc.
      trainers with real experience / competence in low energy sustainable building.
      technical understanding within Awarding Organisations and SSC’s
    • Sustainable building skills strategy
      Clarify key knowledge & skills issues
      Understand business / economic implications of: a) having those skills; b) not having those skills.
      Work out individual & company skills needs & skills gaps
      Put in place:
      Knowledge & skills plan
      Implement quality training system: including quality trainers, progression routes, etc
