Potential for natural ventilation – retail assessments

For industrial and retail buildings the ‘potential for natural ventilation’ requirements apply only to office areas. IfΒ a retailΒ building does not contain any office areas, compliance is met by default.

Whilst the requirements apply to permanently or semi-permanently occupied offices, small admin areas, which are used only occasionally, can be excluded.

This also applies to shell only and shell and core projects, where it can be demonstrated thatΒ no office spaces will be provided, as part of the fit-out.
