F19Interpretation of this standard
In this standard—
“energy from renewable sources” means energy from renewable non-fossil sources, namely wind, solar, aero-thermal, geothermal, hydrothermal and ocean energy, hydropower, biomass, landfill gas, sewage treatment plant gas and biogases; and
“nearly zero-energy building” means a building that has a very high energy performance, as determined in accordance with a methodology approved under regulation 7 of the Energy Performance of Buildings (Scotland) Regulations 2008 F20, where the nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy from renewable sources produced on site or nearby.

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Insulation of pipes, ducts and vessels6.4
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.
Limitation
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;
F5b
buildings, or parts of a building, which will not be heated, other than heating provided solely for the purpose of frost protection; or
c
pipes, ducts or vessels that form part of an isolated industrial or commercial process.
Artificial and display lighting6.5
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.
F6Limitation
This standard does not apply to–
a
process and emergency lighting components in a building; or
b
alterations to a dwelling or a building ancillary to a dwelling.
Mechanical ventilation and air conditioning6.6
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
F9... the ventilating and cooling systems installed are energy efficient and are capable of being controlled to achieve optimum energy efficiency.
Limitation
This standard does not apply to buildings which do not use fuel or power for ventilating or cooling the internal environment.
Commissioning building services6.7
Every building must be designed and constructed in such a way that energy supply systems F25, control 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 F26effective operation and optimum energy efficiency.
Limitation
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 information6.8
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.
Limitation
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;

Energy Performance Certificates6.9
Every building must be designed and constructed in such a way that–
F2a
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.
Limitation

Interpretation of this standard
In this standard, “emergency heating” means a fixed combustion appliance installation which is installed to be used only in the event of the failure of the heating or hot water service system which is designed and installed for use during normal operation of the building.
