Excluding large untreated warehouse spaces from ‘Useful floor area’

For industrial buildings, where there are offices and the untreated warehouse space does not include any energy-intensive systems or processes, the warehouse space can be excluded from the calculation of ‘useful floor area’ to determine whether Criterion 2 or 3 (Criterion 2 only in UK New Construction 2018) is applicable.

For speculative developments, if Planning Consent includes Distribution or Warehousing (UK Planning Use Class B8 or equivalent local planning consent) and the design team and assessor can justify that this is the intended use, the above approach can be followed for untreated warehouse space.

Where there is minimal energy consumption, complex sub-metering such a space would add little benefit.
