Criterion 5 - Provisions for energy-efficient operation of the building

4.1 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.

Information about use of fuel and power

40. (1) This regulation applies where paragraph L1 of Schedule 1 imposes a requirement relating to building work.

(2) The person carrying out the building work shall not later than five days after the work has been completed provide to the owner 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.

Building log book

4.2 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.

4.3 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.
