Whilst the majority of passive measures can only be influenced in the base-build, for a Part 2 and 3 assessment it is considered that those listed in the ‘Passive design analysis’ CN should be reviewed in terms of what can be done with the assessment scope (which may be limited to the last 4 measures for example). Where any of the listed items are not considered, as long as justification is provided in terms why these have not / cannot be considered, this would be acceptable.
Consideration should also be given to what passive design features were incorporated in the base-build and how these are carried through into the fit-out. For example, a passive ventilation strategy in the base-build, must be maintained in the fit-out, rather than sealing all the windows and installing air-conditioning.
In conclusion, in order to ensure a sustainable fit-out, full consideration must be given to how any passive measures from the base-build are maintained or enhanced and any additional measures which can be implemented in the assessment scope.
