[Equest-users] Solartube (Tubular Daylighting System)

[Mathew Higgins]

Kosuke - I haven't seen that you've received a response, but I regularly 
simulate Solartube skylights without a hitch. A couple of things I keep 
in mind when doing so are...

- Making sure to convert the rounded area of the tube to a square dimension
- Ensuring that the tube depth (or light well) extends below a drop 
ceiling or equivalent attic

- Assigning the appropriate space with the daylight sensor(s)
- Making sure that the correct number of sensors and corresponding 
daylight area (ratio) per sensor is accounted for
- Additionally, ensuring that the appropriate foot-candle level, 
location, rotation, and control strategy are input for sensors
