Sefaira’s newest updates allow architects to visualize Daylight Factor and variable illuminance levels.

1. Visualizing Daylight Factor
& Illuminance Levels

2. Extended Daylight Analysis Capabilities
Sefaira recently released two
upgrades that expanded the scope
and flexibility of our daylighting
analysis:
● Daylight Factor visualization
● Adjustable lux thresholds for
Spatial Daylight Autonomy.

3. Benefits for designers
● Toggle quickly between Daylight Factor & Spatial Daylight
Autonomy visualizations and get early feedback when trying
to hit specific daylighting targets.

4. What’s the difference?
● Daylight Factor is a simple ratio of
exterior and interior illuminance
under an overcast sky.
● Spatial Daylight Autonomy, on
the other hand, utilizes location-
based weather data over the
course of an entire year.

5. Additional software capability
Adjustable Illuminance Levels
Architects can also
adjust the illumination
threshold for the
Spatial Daylight
Autonomy
visualization.

6. Additional software capability
Adjustable Illuminance Levels
This visual shows
the % of occupied
hours when work
planes receive
enough light.

7. Additional software capability
Adjustable Illuminance Levels
The threshold for
“enough light” is
initially set to 300 lux
— a standard level
for an office — but
can be quickly
adjusted, using built-
in benchmarks as a
guide.

8. If you are a customer and would like to start using daylight
visualization, simply reach out to your customer success
representative or email support@sefaira.com, and we’ll get
in touch with you.
