Hi to all,

I'm trying to simulate a building wich have a protected façade with fixed horizontal fins and swivelling vertical fins that rotate watching the sun.

My question is, how can i replicate this situation in therms of peak loads and, more important, in annual simulation?!

Thanks in advance!

Hi,

I encountered something similar to this a few years back, when a client planned to build a house with one almost fully glazed wall that rotated to follow the sun.

To the best of my knowledge you can't change the position of geometry during a dynamic simulation.

What we ended up doing was looking at the performance over a typical day, setting the position of the house every hour then rerunning suncast etc.

This gave us a feel for how it may perform compared to a house that didn't move.

You may be able to enter something to represent the additional shading effect dynamically. Perhaps applying external shade to the window construction type. This will allow you to set the shading performance to follow a profile you create.

If you can match these results to your inital study over one day it could be a reasonable approximation.

Hope this helps

This seems very useful to me.

But i could use any other help...any opinions will be appreciated.

I concurr with Ross, that method whilst labour intensive would give you a good feel.
