Hi all,
For SunCast module, it is necessary to set the direction of building or just select the weather data?

Hi chinong,

If you know the orientation of your building I would always suggest setting the site rotation for better, more accurate simulation results.
The amount of solar gains your building receives can have a big impact on the design of your building (whether it's changing the type of constructions/glazing used; adding shading devices; using a different hvac system and so on).
If really depends on what you're trying to achieve with the software.

Hi John,

Thanks for yours reply. So how can I set the orientation of the building? It is set according to North,South, East and West?

The Site Rotation button on the main toolbar allows you to set the building's orientation in degrees from North.

Hi, John

Meaning if the arrow facing upward, the side is heading North? Thank a lot
