BUILDING REGULATIONS 2002

BUILDING REGULATIONS – ENERGY EFFICIENCY PROVISIONS

ENGLAND AND WALES BUILDING REGULATIONS PART L: NEWS & DOWNLOADS

SCOTLAND BUILDING REGULATIONS PART J: NEWS & DOWNLOADS

DOMESTIC BUILDINGS – Part L1/ J – achieving compliance

NON DOMESTIC BUILDINGS – Part L2 – achieving compliance

DWELLINGS – (PART L1)

KCE provide a full service in designing to comply with the energy efficiency provisions and in certifying compliance

For a detailed description of the domestic buildings Part L1 regulations and the KCE service, click here or phone Stephen Kinsella, 01934 838624, [email protected]
A BRIEF SUMMARY  of  PART L1 / J:

Dwellings have to comply with regulations under any one of three methods:

• ELEMENTAL METHOD

The traditional approach, based on U values of elements, modified according to heating system efficiency

• TARGET U VALUE METHOD

This method enables more efficient heating systems to offset the U-value requirements. Can enable less onerous U-values.

• CARBON INDEX METHOD

This is calculated through the Standard Assessment Procedure, but unlike the SAP rating, is independent of fuel costs. As with the SAP rating, the carbon index takes into account all the design factors affecting energy use, including size, shape and orientation. Through suitable design it is possible to comply under the carbon index criterion when compliance is not achieved under the other methods, giving the most flexibility to the designer.
The SAP RATING must be calculated and displayed in the new dwelling on completion.

NON – DOMESTIC BUILDINGS – (PART L2)

For assessment of your building design for Building Regulations L2 compliance, send the drawings to Stephen Kinsella, KCE Energy and Environment, The Old Forge, Kingston Bridge, Clevedon, Somerset, BS21 6TX.  Phone me on 01934 838624 or email [email protected]
I carry out integrated calculation of all three methods of compliance and provide you with:

1.  A report on the optimum means of complying with part L2
2.  Carbon emissions achieved
3.  Certificate of L2 compliance.  

I will first advise you of the cost of the assessment and will agree the programme with you. Payment must be made before the start of the assessement.

A BRIEF SUMMARY  of  PART L2:

A.  DESIGN compliance is achievable via one of 3 routes:

A1. Elemental methodOr A2. Whole Building method (for offices, schools and hospitals only)Or A3. Carbon Emissions method
B.  CONSTRUCTION compliance takes into account:
Thermal bridging methods or thermographic survey (buildings over 1000 m² ).Airtightness (Pressurisation test for buildings over 1000 m ²).Commissioning report.
C.  INFORMATION compliance takes into account:
Log Book.Metering Strategy.Calculation of carbon emissions (for offices over 200 m ² ).

DESIGN

1. The Elemental Method takes into account these factors in the design:

1. U values2. Thermal bridging3. Opening areas4. Air leakage5. Solar overheating6. Carbon intensity of heat generating equipment7. Heating controls8. Hot water controls9. Insulation of pipes and vessels10. Lighting methods (shop displays are exempt)11. Lighting controls12 Air conditioning and mechanical ventilation systems
2. The Whole Building method of design for offices takes into account:
1. Whole office carbon performance rating2. Air leakage3. U values

For Schools and Hospitals the design must comply with relevant DfEE/ NHS guides.
3. The Carbon Emissions Method of design takes into account calculation of:
1. Carbon emissions of a ‘reference building’ designed to the Elemental Method
2. Carbon emissions of the proposed buildingThus the Carbon Emissions Method needs full consideration of the Elemental Method, then allows adjustment (within limits), enabling considerable freedom of design.

Buildings need to be designed under the Carbon Emissions method rather than the traditional elemental or target U value method in order to reflect all the benefits of energy efficient design.

KCE provide a full service in designing to comply with the energy efficiency provisions and in certifying compliance.
