O N L I N E V E R S I O N C Appendix C: Reporting evidence of compliance BRUKL report C1 The Building Regulations UK Part L (BRUKL) report should be provided to the building control body and to the building owner to show that building work complies with the energy efficiency requirements. C2 The Simplified Building Energy Model (SBEM) will produce the BRUKL report for the building as a standard output option. C3 Two versions of the BRUKL report should be produced, using the approved software. a. The first, the design stage BRUKL report, before works begin, to include all of the following. i. The target primary energy rate and building primary energy rate. ii. The target emission rate and building emission rate. iii. A supporting list of specifications. b. The second, the as-built BRUKL report, to include all of the following. i. The target primary energy rate and as-built building primary energy rate. ii. The target emission rate and as-built building emission rate. iii. A supporting list of specifications and any changes to the list of specifications that was provided at design stage. The building control body can then use these reports to help check that what was designed has been built. The software includes a facility to compare the design stage and as-built data input files and automatically produces a schedule of changes. C4 The as-built BRUKL report should be signed by the energy assessor to confirm that the as-built calculations are accurate. C5 The as-built BRUKL report must be signed by the client (usually the developer or housebuilder) to confirm that the building has been constructed or completed according to the specifications in the report. 93 Building Regulations 2010 Approved Document L Volume 2, 2021 edition O N L I N E V E R S I O N
