In general, BREEAM annual daylighting results for HEA-01 Visual
Comfort are not comparable to other apparently equivalent calculations
such as sDA and UDI. This is because the acceptance criteria method
used is different.
By default the sDA results map ...
> 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 ...
DesignBuilder v7 sees a major upgrade of our daylighting tools.
Highlights include:
• Annual Climate Based Daylight Modelling simulations are now run
directly in Radiance, fully implementing the method specified in
LM-83-12 and including dynamic blinds f...
DesignBuilder v7.0 does not have the solar tube object for the
Daylighting calculation.
One work around would be to use rooflights but this will only be
applicable for blocks with external roof.
Its more complicated with basement zones without external ...
_DA - Daylight autonomy is defined as “the percentage of the
operating period (or number of hours) that a particular daylight level
is exceeded throughout the year.” _
This is different than SDA - SPACIAL DAYLIGHT AUTONOMY output that is

Question: Do annual daylight simulations use the weather file
associated to thermal model on site level?
Answer: Yes, the weather file is used to produce a matrix of sky
patch values using the Perez all weather model. The input file
contains a short hea...
There are 2 known causes of this problem:
1. Failure in the installation of the Radiance software. You can
check to see if this is the cause by going to the DesignBuilder
Radiance folder ("File > Folders > Radiance folder" menu command opens
