6.8 Written Information
Correct use and appropriate maintenance of building services equipment is essential if the benefits of enhanced energy efficiency are to be realised from such equipment. The intention of this standard is to make the information that will help achieve this, available to the occupier of the building.
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 user and maintenance instructions to enable efficient use unless they are exempt under schedule 1, regulation 3.
Power plants which serve a number of buildings (e.g. an industrial estate) and only export surplus electricity to the National Grid will also need to have user and maintenance instructions, unless exempt in terms of schedule 1, regulation 3.
Instructions on taking readings from the automatic monitoring and targeting systems (AM&T), when present, should be provided to ensure the benefits of the installation are realised.
A logbook should be provided and contain information about all aspects of energy system operation and maintenance to enable the building user to optimise the use of fuel. This should include detailed information on building services plant and controls.
CIBSE Technical Memorandum 31 (TM31) (http://www.cibse.org/) provides guidance on the presentation of a logbook, and the logbook information should be presented in this or a similar manner.
It is recognised that some alterations to building services, because they are done on a piecemeal basis, will not result in optimum energy efficiency being attained for the entire system. Where this occurs, the person responsible for the commissioning of that part of the system should make available to the owner and occupier, a list of recommendations that will improve the overall energy efficiency of the system.
On completion of the extension or alteration to the building services system, the commissioning information should be updated in the logbooks.
