[Equest-users] Shading

[Keith Swartz]

Shalini,

If I understand your "movable shading" right as a retractable awning, one technique to consider is setting up a schedule that changes the transparency of the shading overhang so that it is opaque when you want the shade out and transparent when you want the shade retracted. You could model multiple positions of the shade by splitting the shade into multiple sections. For example, if the shade is extended only half way out at times, divide the shade into two halves and make the half closest to the wall opaque while the outer half is transparent.

Thanks, Ashu. Yes, I modeled overhangs (but not fins). I want to model movable shading, which moves according to the movement of sun specially in the east side to prevent overheating. So I was wondering if designing some schedules will be helpful and if so, how to do that. Would you suggest that overhangs and fins are all I would need (for a heating dominated region) instead of movable shading?

Hey Shalini,

Have you modeled the overhangs and fins in exterior shading? Can you elaborate that what kind of movable shading you want to model.

Thanks,
Ashu

Hello all,

Am trying to model a small commercial building in Toronto and applying as many passive techniques as I can. While designing shading, I want to apply movable exterior shading (please advice if this will be one of the best techniques or there is a better option). Can anyone share any example with appropriate shading schedules designed. I specific need guidance in designing these schedules. How do we take into consideration the assigned weather file in doing so?

Your response and help will be greatly appreciated.

Thanks,

Shalini
