SECTION 6 - SCOTLAND ENERGY CONSULTANTS

SECTION 6 - SCOTLAND ENERGY CONSULTANTS

SECTION 6 - ENERGY SCOTLAND - EXPLAINED

The intention of Section 6 is to ensure that effective measures for the conservation of fuel and power are incorporated in buildings. In addition to limiting energy demand by addressing the performance of the building fabric and fixed building services, a carbon dioxide emissions standard obliges designers of new buildings to consider building design in a holistic way. Our Section 6 Energy Consultants are fully qualified to verify compliance with the Section 6 – Energy Guides. Our internal Level 5 Energy Consultants will ensure that compliance is achieved in the most efficient manner possible, providing value for money. We are unique Energy Consultants with Regional Offices throughout the UK.

Similar to Part L, the standard focuses on the Criterions 1-5 for compliance, using the National calculation methodology (NCM) as approved in the building regulations. The standards are very similar to each other, and have slight differences throughout.

Section 6 advised on nine standards to demonstrate evidence in complying with the building regulations, each of those standards are outlined below with the required evidence detailed.

Regulation 25A – Low to Zero Carbon Energy Statements

Regulation 25A requires that, before the work starts, the person undertaking the work must carry out an analysis that considers and takes into account the technical, environmental and economic feasibility of using high-efficiency alternative systems in the building design. The following high- efficiency alternative systems may be considered if available, but other LZC systems may also be considered if available:

  • decentralised energy supply systems based on energy from renewable sources;
  • district or block heating or cooling, particularly where it is based entirely or partially on energy from renewable sources;
  • heat pumps.

The analysis should state whether high-efficiency alternative systems have or have not been included in the building design. The requirement relates to considering, taking into account, documenting and making available for verification purposes the analysis of high-efficiency alternative systems.

NOTE: The Building Regulations are technology neutral and do not require that high-efficiency alternative systems or other LZC systems are installed.

Demonstrating Compliance with 25A - Guidance for Section 6

Regulation 25A essentially states that proof of the building passing the Criterion, and proof of consideration for LZC technologies must be given in order for planning permission to be obtained.

Proof is delivered within the BRUKL document obtained from the SBEM calculation methodology, and evidence within the energy statement of alternative energy resources. The statement must explain why certain technologies have been avoided, and reasonable explanation for all.

An SBEM is the Simple Building Energy Model, and is purposely used as a national calculation method for comparing buildings of the same type. The SBEM calculated a carbon output, called the Building Emission Rate. This building emission rate is then compared against the target emission rate, to tell if there is a pass or fail. Effectively, the calculation is in place to ensure that all buildings meet a certain level of energy efficiency in terms of carbon emissions.

JPA M&E Consultants will guide you through each stage and will carry out the Energy Statement to get through planning successfully.

Standard 6.1 - Regulation 26

Every building must be designed and constructed in such a way that:

the energy performance is estimated in accordance with a methodology of calculation approved under regulation 7(a) of the Energy Performance of Buildings (Scotland) Regulations 2008, and the energy performance of the building is capable of reducing carbon dioxide emissions.

Limitation:

This standard does not apply to:

    1. alterations and extensions to buildings, other than:
      • alterations and extensions to stand-alone buildings having an area less than 50 square metres that would increase the area to 50 square metres or more
      • extensions to non-domestic buildings where the extension will have an area which is both greater than 100 square metres and greater than 25% of the area of the existing building, and
      • alterations to buildings involving the fit-out of the building shell which is the subject of a continuing requirement
    2. conversions of buildings:
    3. non-domestic buildings and buildings that are ancillary to a dwelling that are stand-alone having an area less than 50 square metres
    4. buildings, which will not be heated or cooled, other than by heating provided solely for the purpose of frost protection, or
    5. limited life buildings which have an intended life of less than 2 years.

Demonstrating Compliance with Section 6.1 - Guidance

In the Secretary of State’s view, compliance with the energy efficiency requirements could be demonstrated by meeting the five separate criteria set out in the following paragraphs. Compliance software should produce an output report to assist BCBs check that compliance has been achieved.

NOTE: The output report can benefit both developers and BCBs during the design and construction stages as well as at completion.

In accordance with regulation 26, the calculated CO2 emission rate for the building (the Building CO2 Emission Rate, BER) must not be greater than the Target CO2 Emission Rate (TER).

Evidence for compliance:-

To demonstrate that the requirement in regulation 26 has been met, the actual Building CO2 Emission Rate (BER) must be no greater (no worse) than the TER calculated from the NCM calculation methodology, approved by the government bodies. 

The TER is established by using approved software to calculate the CO2 emission rate from a notional building of the same size and shape as the actual building, but with specified properties. These specified properties shall be as set out in the National Calculation Methodology (NCM) modelling guide, in the section headed ‘Detailed definition of Notional Building for buildings other than dwellings’. The TER is set equal to the CO2 emissions from this notional building, with no further adjustment being made.

NOTE: The TER is based on a building of the same size and shape as the actual building, constructed to a concurrent specification. This concurrent specification for Section 6 is given in the NCM modelling guide. Developers are still given the freedom to vary the specification, provided the same overall level of CO2 emissions is achieved or bettered.

Standard 6.2 - Limiting U Values

Every building must be designed and constructed in such a way that an insulation envelope is provided which reduces heat loss.

Limitation:

This standard does not apply to:

  • non-domestic buildings which will not be heated, other than heating provided solely for the purposes of frost protection
  • communal parts of domestic buildings which will not be heated, other than heating provided solely for the purposes of frost protection, or
  • buildings which are ancillary to dwellings, other than conservatories, which are either unheated or provided with heating which is solely for the purpose of frost protection.

Demonstrating Compliance with Section 6.2 - Guidance

Buildings should be constructed and equipped so that performance is consistent with the calculated BER. As indicated in paragraph 2.15, a calculation of the BER is required to be submitted to the BCB after completion to take account of:

  • any changes in performance between design and construction; and
  • the achieved air permeability, ductwork leakage and commissioned fan performance.

Final fabric U-Values and thermal properties shall be no worse than those shown in the table below. An air test is to be carried out on construction to prove the air permeability value.

Limiting U Values & Thermal Properties - Section 6

Roof 0.25 W/(m^2K)
Wall 0.35 W/(m^2K)
Floor 0.25 W/(m^2K)
Swimming pool basin 0.25 W/(m^2K)

Limitation:

This standard does not apply to:

  • buildings which do not use fuel or power for controlling the temperature of the internal environment, or
  • heating provided solely for the purpose of frost protection.
Note on Consequential improvement

Where work to an existing building is subject to a building warrant and includes the provision of new fixed building services or alters or extends the capacity of existing fixed building services, the opportunity should be taken to review and improve the performance of fixed building systems.

Guidance on the extent to which improvement should be made is given in annex 6.D – ‘Improvement to the energy performance of existing building services when carrying out building work’.

  • solar control methods have been adopted
  • Criterion 3 of the BRUKL document has been satisfied.

Standard 6.7 - Building Commissioning

Standard 6.7

Every building must be designed and constructed in such a way that energy supply systems and building services which use fuel or power for heating, lighting, ventilating and cooling the internal environment and heating the water, are commissioned to achieve optimum energy efficiency.

Limitation:

  • This standard does not apply to:
  • major power plants serving the National Grid
  • the process and emergency lighting components of a building
  • heating provided solely for the purpose of frost protection, or
  • energy supply systems used solely for industrial and commercial processes, leisure use and emergency use within a building.

Demonstrating Compliance with Section 6.7 - Guidance

Evidence for compliance:-

  • Ductwork leakage tests comply with ductwork recommendations (DW143)
  • Commissioning has been carried out in line with CIBSE recommendations.
  • Work has been inspected by others.

Standard 6.8 - Building Log Book

The occupiers of a building must be provided with written information by the owner:

  • on the operation and maintenance of the building services and energy supply systems, and
  • where any air-conditioning system in the building is subject to regulation 17, stating a time-based interval for inspection of the system.

Limitation:

This standard does not apply to:

  • major power plants serving the National Grid
  • buildings which do not use fuel or power for heating, lighting, ventilating and cooling the internal environment and heating the water supply services
  • the process and emergency lighting components of a building
  • heating provided solely for the purpose of frost protection
  • lighting systems in a domestic building, or
  • energy supply systems used solely for industrial and commercial processes, leisure use and emergency use within a building.

Demonstrating Compliance with Section 6.8 - Guidance

In accordance with regulation 40, the owner of the building should be provided with sufficient information about the building, the fixed building services and their maintenance requirements so that the building can be operated in such a manner as to use no more fuel and power than is reasonable in the circumstances

A way of showing compliance with regulation 40 would be to produce information following the guidance in CIBSE TM 31 Building log book toolkit. The information should be presented in templates as or similar to those in TM 31. The information could draw on or refer to information available as part of other documentation, such as the Operation and Maintenance Manuals and the Health and Safety file required by the Construction (Design and Management) (CDM) Regulations.

NOTE: Further advice is provided in BSRIA BG 26/2011 Building manuals and building user guides.

The data used to calculate the TER and the BER should be included with the log book. The occupier should also be provided with the recommendations report generated with the ‘on-construction’ energy performance certificate. This will inform the occupier how the energy performance of the building might be further improved.

NOTE: It would also be sensible to retain an electronic copy of the TER/BER input file for the energy calculation to facilitate any future analysis that may be required by the owner when altering or improving the building.

Standard 6.9 - Energy Performance Certificates

Every building must be designed and constructed in such a way that:

  1. an energy performance certificate for the building is affixed to the building, and *
  2. (removed)
  3. the energy performance certificate is displayed in a prominent place within the building.

Limitation:

this standard does not apply to:

  1. buildings which do not use fuel or power for controlling the temperature of the internal environment
  1. non-domestic buildings and buildings that are ancillary to a dwelling that are standalone having an area less than 50 square metres
  1. conversions, alterations and extensions to buildings other than—
    • alterations and extensions to stand-alone buildings having an area less than 50 square metres that would increase the area to 50 square metres or more, and
    • alterations to buildings involving the fit-out of the building shell which is the subject of a continuing requirement, or
  1. limited life buildings which have an intended life of less than 2 years

Standard 6.9(c) only applies to buildings:

  • with a floor area of more than 250 square metres
  • into which members of the public have an express or implied licence to enter, and
