  3. 3. Session 1 Niall Gibson© Integrated Environmental Solutions Ltd.
  4. 4. From EPBD to Present© Integrated Environmental Solutions Ltd.
  5. 5. The Origins of Part L • First introduced in 1985 following 1984 Building Act: Regulated heating systems and Insulation of services • Revised in 1990 and again in 1995 to regulate the “Conservation of Fuel and Power” • 2002: – L1(Dwellings) & L2(Non-Dwellings) – 3 methods for Compliance – Elemental, Whole Building Method or Carbon Emissions Calculation Method – SAP used to calculate Carbon Emissions for dwellings • 2006: – L1A and L2A (New Build) & L1B and L2B (Existing Buildings) – Introduction of SBEM for Non-Dwelling Compliance – 1 Single method of compliance through 5 Criteria – BER Vs TER or DER Vs TER – Improved standards for U-Values and plant efficiency etc© Integrated Environmental Solutions Ltd.
  6. 6. The Origins of EPC’s • European performance of Buildings Directive (EPBD) state the requirements of Energy Performance Certificate (EPC) within: – Article 10 – Article 11 – Article 12 • EPC’s first appearance in the UK in 2008© Integrated Environmental Solutions Ltd.
  7. 7. ….and Today! • Part L 2010…….© Integrated Environmental Solutions Ltd.
  8. 8. Where Are We Now© Integrated Environmental Solutions Ltd.
  9. 9. Part L2A 2010 Criterion 1 – Achieving the BER • Target Emission Rate (TER) calculation changed significantly. • TER now determined by a new 2010 Notional Building. • Improvement Factors and Low Zero Carbon Factors have been removed. • The 2010 Part L2A is intended to achieve an aggregate reduction of 25%. • The reduction therefore between building types will vary.© Integrated Environmental Solutions Ltd.
  10. 10. Part L2A 2010 Criterion 2 – Limits on Design Flexibility • Limiting Average U-values typically the same as 2006 Regulations. • System Efficiencies and controls should meet the minimum provisions set out in the “Non-Domestic Building Services Compliance Guide”. • Minimum requirements for Lighting Efficiency now falls under Criterion 2.© Integrated Environmental Solutions Ltd.
  11. 11. Part L2A 2010 Criterion 3 – Limiting the Effects of Solar Gains in Summer • Significant Change in Calculation Method from L2A 2006 Regulations • Now only one means to demonstrate compliance. • Compliance is met by showing that aggregated Solar Gain does not exceed a Benchmark level. • Applicable to all occupied, non transient spaces regardless of their conditioning level. • IESVE would always reiterate the importance of investigating overheating© Integrated Environmental Solutions Ltd.
  12. 12. The 2010 Notional Building The Target Emission Rate • The TER is now the Notional Building Emission Rate • Improvement Factors and Low Zero Carbon Factors no longer exist in calculation • The 2010 NCM Modelling Guide details the properties for the 2010 Notional Building. • This new approach has the advantage of allowing the Actual and Notional Buildings to be directly compared to identify key areas where improvement is required.© Integrated Environmental Solutions Ltd.
  13. 13. Part L 2010 2010 keys points: •25% improvement over 2006 standards for New Build (Aggregate Approach) •Minor Alterations to SBEM to reflect changes •Criterion 3 – Overheating calculations simplified calculations, onerous compliance •Thermal bridging constraints •Compliance required with Design Stage submission pre-start •25% proved challenging (Good Holistic design essential, vehicle for BIM?!) •2013 is around the corner and 2016 seems much closer….. – Zero carbon Homes & Schools by 2016 – All Public Building stock by 2018 – All new build by 2019© Integrated Environmental Solutions Ltd.
  14. 14. Accreditation IES Certification • Frequent online and face to face training sessions offered to meet customers needs – contact for more information. • IES Accreditation exams covering Levels 3, 4 & 5 available at test centres across the country.© Integrated Environmental Solutions Ltd.
  15. 15. What’s Coming in the Future© Integrated Environmental Solutions Ltd.
  16. 16. “from 2016 all new homes, and from 2019 all new non- domestic buildings, will be built to zero carbon standards.” Rt Hon Grant Shapps MP© Integrated Environmental Solutions Ltd.
  17. 17. Zero Carbon Definition • The proposed new definition is simply represented (below). – the target for Carbon Compliance is currently expected to be a 70% reduction of regulated energy use compared to 2006 Standards. “ Source:© Integrated Environmental Solutions Ltd.
  18. 18. The Green Deal • Market driven approach with parameters set by Government. • New financing arrangement – attached to the meter. • Install a package of measures that pays for itself over time. • Support for poorer households and certain installations • Consultations has now closed – received over 600 responses. • Government will publish formal responses in late spring 2012. • Launch of Green Deal in October 2012 for Domestic. – Non-Domestic to follow later© Integrated Environmental Solutions Ltd.
  19. 19. The Green Deal Overview DECC Oversight Body BSI PAS Installer UKAS Standard / Advisor Accrediting Standard Green Deal Code of Standards Practice (Accredited) Certification Bodies Approved (Certified) Advisors & Installers Issues Quality Green Deal Advisor Mark Qualifications© Integrated Environmental Solutions Ltd.
  20. 20. Green Deal Process Remote Advice: •Independent and Impartial advice via telephone and internet •Signposting service to other parts of the Green Deal e.g. assessment, installation etc© Integrated Environmental Solutions Ltd.
  21. 21. Green Deal Process Assessment: •Only an accredited assessor can produce report •Standardised, impartial assessment including: • Fabric Assessment • Other advice, including behavioural© Integrated Environmental Solutions Ltd.
  22. 22. Green Deal Process Finance: •New Finance mechanism – attached to the energy meter and paid back over time through savings on energy bills •Obligation passes to whoever pays the bill at the property, so transfers automatically to any new occupier© Integrated Environmental Solutions Ltd.
  23. 23. Green Deal Process Installation: •Accredited installers carry out work to a clear standard •Sign off work once complete and inform Green Deal provider that repayments can begin© Integrated Environmental Solutions Ltd.
  24. 24. Green Deal Process Repayments and follow up: •Payments collected through energy bills with the Green Deal charge shown as a separate line on the bill •Continuing support from the Green Deal provider throughout Green Deal •Customer is free to switch energy supplier – no change to current procedures© Integrated Environmental Solutions Ltd.
  25. 25. The Golden Rule The Golden Rule is the principle which limits the amount of Green Deal finance that a provider can attach to the likely energy bill savings by the measures installed Protects consumers of higher energy bills and investors from a higher risk of default on the bill.© Integrated Environmental Solutions Ltd.
  26. 26. The Golden Rule The Assessment The advisor will produce an Energy Performance Certificate (EPC) alongside an appropriate package of measures In addition to An assessment of how the occupants use their energy in their home through the Occupant Assessment© Integrated Environmental Solutions Ltd.
  27. 27. Agreed Changes to Domestic Assessment • Assessment methodology by an improved RdSAP • Changes include: – Regional weather, orientation and exposure – Partial coverage (room by room approach) – Additional energy efficiency measures – Indication of likely to meet Golden Rule – Revised EPC format© Integrated Environmental Solutions Ltd.
  28. 28. Non-Domestic Assessment • Based on existing energy calculation tool SBEM. • Currently in development and being piloted by BRE • Additional functionalities to be expected: – Allow the assessor to tailor the model to the building occupiers actual operating regime – Enable the assessor to more easily explore and document the savings in energy use resulting from the installation of one or more energy efficiency measures, in one or more packages or measures. – Accept information on fuel costs, so as to calculate the approximate value of these energy savings.© Integrated Environmental Solutions Ltd.
  29. 29. Energy Companies • Fundamental concept is that the Green Deal payments will be collected as part of the energy bills • This facilitates automatic transfer of charge between collectors if supplier is changed or properties change hands • Supplier with less than 250,000 customers are not obliged to collect • Electricity supplier will be collecting the Green Deal charge as an agent or trustee of the Green Deal provider • Payments passed to the green Deal provider within 72hrs • Ability to switch is not restricted assuming new supplier is participating in the payment collection mechanism© Integrated Environmental Solutions Ltd.
  30. 30. Installers • Only authorised Green Deal installers can undertake the works • Will be able to use the ‘Green Deal Mark’ • Are certified by an accreditation body against the relevant Green Deal standards set out in the Code of Practice • Are a member of the certification body which certifies them • Agree to comply with the Code of Practice • Possible top up training required against current industry recognised installation requirements • Consumer could choose to go directly to Green Deal provider or an independent installer to carry out the work • Complaints handled by Green Deal provider who may take the matter to the certification body • There will be an over sight body.© Integrated Environmental Solutions Ltd.
  31. 31. Green Deal Providers • Responsible for the provision of Finance and Arranging energy efficiency works • Offers a Green Deal Plan based on the recommendation from an accredited assessor • Must include consumer protections such as warranties • Arranges installations from an authorised installer • Have a complaints handling procedure • Provide information to new bill payer (must keep records)© Integrated Environmental Solutions Ltd.

Social landlords •Who takes out the Green Deal, Landlord or Tenant – Could be either but tenant would require Landlord approval •Landlord is liable in voids periods •Bill payer is liable for default© Integrated Environmental Solutions Ltd.
  36. 36. Points of Note • Domestic Green Deal to be launched in October 2012, Non- Domestic TBC! • RdSAP/SBEM vs DSM • Eligibility of efficiency measures • Favours Non-Domestic over Domestic • What measures will be in place to curb GD Assessors’ inclination to inflate predicted savings • What protection will be provided to consumers • Will building owners willingly burden their home with a GD commitment binding on future purchasers? • Will enough GD assessors be trained up by October 2012 to make non-domestic Green Deal viable at that date?© Integrated Environmental Solutions Ltd.
  37. 37. EPC’s • Government have decided that EPC’s should be made Publically available. • To come into force from April 2012. • Individual users will be able to access PDF EPC’s online directly from the EPC register – at no cost. • Authorised Bulk users include, Public sector, FIT’s Licensees, Green Deal Providers, etc© Integrated Environmental Solutions Ltd.
  38. 38. Current EPC • Current EPC been in use since 2007. • Some positive features. • Research shown majority of home buyers and prospective tenants either do not read their EPC in detail, or at all. • Reasons include: – Document too lengthy – Language too technical – Confusion over ratings – Large amounts of text© Integrated Environmental Solutions Ltd.
  39. 39. New EPC • EPC has undergone a major redesign to ensure it gives consumers the information they need, including: • A much more professional design with better use of graphics and white space. • Getting rid of jargon and making it more consumer-friendly with plain English used throughout • A very clear emphasis on the financial costs and benefits of various measures • Clear signposting to the Green Deal and information on which measures qualify for Green Deal finance© Integrated Environmental Solutions Ltd.
