Commissioning in terms of this section means, raising the building services systems covered by this guidance from a level of static completion to full working order and achieving the levels of energy efficiency that the component manufacturers expect from their product(s). Commissioning however, should also be carried out with a view to enabling the safe operation of the installation.
Although there is no requirement within Section 6 for minimum efficiency levels of either, building-integrated or localised energy supply systems (e.g. diesel generators, micro wind turbines or photovoltaic arrays), there is a need for commissioning to be carried out to enable efficient use, unless they are exempt under schedule 1, regulation 3. Power plants which serve a number of buildings (e.g. housing estates) and only export surplus electricity to the National Grid will also need to be commissioned, unless exempt in terms of schedule 1, regulation 3.
All heating, hot water service, ventilating or cooling systems and any decentralised equipment for power generation in a dwelling or other area of a building consisting of dwellings should be inspected and commissioned in accordance with manufacturers’ instructions to enable optimum energy efficiency.
Guidance and supplementary information to assist the commissioning of installed building services is given in the Domestic Building Services Compliance Guide for Scotland http://www.scotland.gov.uk/Topics/Built-Environment/Building/Building-standards/techbooks/techhandbooks/dbscgs. The document is intended to support standardisation of the specification and expected performance of fixed building services throughout the UK. The guidance applies to new and replacement systems and components.
