How to generate Spatial Daylight Autonomy for a Single Day

>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.
