Technical Clarification Number

Guidance
2015-02-04

When a Daylight Modelling Report is provided including:
• legible floor plan outputs from the daylight modelling for each plan area claimed to have either a DF of not less than 2.0%, or a DI of at least 250 Lux and
• a summary table that identifies all spaces within the building’s UA, nominates spaces that comply and their area, identifies the DF or DI value within those spaces, and provides calculations to confirm that compliant areas jointly contribute to the claimed percentage of the UA,

then it is not required to overlay results on the architectural drawings, this requirement is specific to the hand calculation method only.
