Approved Document L2 lays down a number of further requirements in addition to those that can be tested by the three methods described above. These are summarised below:
Construction – requirements on the methods used to construct the building
Providing information – requirements to provide the owner and/or occupier of the building with information about the building and its systems. The information should include, for systems serving an office area of more than 200 m2, a design assessment of the building services systems’ carbon emissions and the comparable performance benchmark. In the case of the Whole-building (Office) Method, this information is provided in the <Virtual Environment> Part L results file. In the case of the Carbon Emissions Method, it would be provided by the results of the carbon emissions calculation.
