[SECTION 6:SENERGY
Carbon dioxide emissionsS
6.1 Every building must be designed and constructed in such a way that–
(a)the energy performance is calculated in accordance with a methodology which is asset based, conforms with the European Directive on the Energy Performance of Buildings 2002/91/EC and uses UK climate data; and
(b)the energy performance of the building is capable of reducing carbon dioxide emissions.
LimitationS
This standard does not apply to–
(a)alterations and extensions to buildings;
(b)conversions of buildings;
(c)non-domestic buildings and buildings that are ancillary to a dwelling that are stand-alone having an area less than 50 square metres;
(d)buildings, which will not be heated or cooled other than by heating provided solely for the purpose of frost protection; or
(e)limited life buildings which have an intended life of less than 2 years.
Building insulation envelopeS
6.2 Every building must be designed and constructed in such a way that an insulation envelope is provided which reduces heat loss.
LimitationS
This standard does not apply to–
(a)non-domestic buildings which will not be heated, other than heating provided solely for the purposes of frost protection;
(b)communal parts of domestic buildings which will not be heated, other than heating provided solely for the purposes of frost protection; or
(c)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.
Heating systemS
6.3 Every building must be designed and constructed in such a way that the heating and hot water service systems installed are energy efficient and are capable of being controlled to achieve optimum energy efficiency.
LimitationS
This standard does not apply to–
(a)buildings which do not use fuel or power for controlling the temperature of the internal environment;
(b)heating provided solely for the purpose of frost protection; or
(c)individual solid-fuel or oil-firing stoves or open-fires, gas or electric fires or room heaters (excluding electric storage and panel heaters) provided as secondary heating in domestic buildings.
Insulation of pipes, ducts and vesselsS
6.4 Every building must be designed and constructed in such a way that temperature loss from heated pipes, ducts and vessels, and temperature gain to cooled pipes and ducts, is resisted.
LimitationS
This standard does not apply to–
(a)buildings which do not use fuel or power for heating or cooling either the internal environment or water services;
(b)buildings, or parts of a building, which will not be heated, other than heating provided solely for the purpose of frost protection;
(c)pipes, ducts or vessels that form part of an isolated industrial or commercial process; or
(d)cooled pipes or ducts in domestic buildings.
Artificial and display lightingS
6.5 Every building must be designed and constructed in such a way that the artificial or display lighting installed is energy efficient and is capable of being controlled to achieve optimum energy efficiency.
LimitationS
This standard does not apply to–
(a)process and emergency lighting components in a building;
(b)communal areas of domestic buildings; or
(c)alterations in dwellings.
Mechanical ventilation and air conditioningS
6.6 Every building must be designed and constructed in such a way that–
(a)the form and fabric of the building minimises the use of mechanical ventilating or cooling systems for cooling purposes; and
(b)in non-domestic buildings, the ventilating and cooling systems installed are energy efficient and are capable of being controlled to achieve optimum energy efficiency.
LimitationS
This standard does not apply to buildings which do not use fuel or power for ventilating or cooling the internal environment.
Commissioning building servicesS
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.
LimitationS
This standard does not apply to–
(a)major power plants serving the National Grid;
(b)the process and emergency lighting components of a building;
(c)heating provided solely for the purpose of frost protection; or
(d)energy supply systems used solely for industrial and commercial processes, leisure use and emergency use within a building.
Written informationS
6.8 The occupiers of a building must be provided with written information by the owner–
(a)on the operation and maintenance of the building services and energy supply systems; and
(b)where any air conditioning system in the building is subject to regulation 17, stating a time based interval for inspection of the system.
LimitationS
This standard does not apply to–
(a)major power plants serving the National Grid;
(b)buildings which do not use fuel or power for heating, lighting, ventilating and cooling the internal environment and heating the water supply services;
(c)the process and emergency lighting components of a building;
(d)heating provided solely for the purpose of frost protection;
(e)lighting, ventilation and cooling systems in a domestic building; or
(f)energy supply systems used solely for industrial and commercial processes, leisure use and emergency use within a building.
Energy Performance CertificatesS
6.9 Every building must be designed and constructed in such a way that–
[(a) an energy performance certificate for the building is affixed to the building; and]
(c)the energy performance certificate is displayed in a prominent place within the building.
LimitationS
(a)This standard does not apply to–
(i)buildings which do not use fuel or power for controlling the temperature of the internal environment;
(ii)non-domestic buildings and buildings that are ancillary to a dwelling that are stand-alone having an area less than 50 square metres;
(iii)conversions, alterations and extensions to buildings; or
(iv)limited life buildings which have an intended life of less than 2 years.
(b)Standard 6.9(c) only applies to buildings with a floor area of more than 1000 square metres, which are occupied by public authorities and institutions providing public services, which can be visited by the public.
MeteringS
6.10 Every building must be designed and constructed in such a way that each part of a building designed for different occupation is fitted with fuel consumption meters.
LimitationS
This standard does not apply to–
(a)communal areas of buildings in different occupation;
(b)district or block heating systems where each part of the building designed for different occupation is fitted with heat meters;
(c)heating fired by solid fuel or biomass; or
(d)heating for individual dwellings fired by LPG or oil.]
