How to generate Spatial Daylight Autonomy for a Single Day
Posted by Luis Sousa on 13-Dec-22 01:14 PM
We need to generate results for one day only (June 21st 0800 - 1800). Is this possible in DesignBuilder?

You will need to create an occupancy schedule (Compact type) for that particular day with three "Through" periods:
- before June 21st,
- on 21st 
- and after the 21st.

Depending on the project location and the hemisphere you can use the following default schedules as a reference, create a copy, and set the 08:00 to 18:00 period:



Or you can create a new custom schedule and copy/paste the example text below:

Schedule:Compact,
8-18 June 21st,
Fraction,
Through: 20 Jun,
For: AllDays,
Until: 24:00, 0,
Through: 21 Jun,
For: AllDays,
Until: 07:00, 0,
Until: 17:00, 1,
Until: 24:00, 0,
Through: 31 Dec,
For: AllDays,
Until: 24:00, 0;

You can do this from the Annual daylighting calculation dialog:



By overriding the Annual daylighting occupancy period to be active only for the day of interest will ensure that your Daylight Autonomy results apply only to that day.
