[esp-r] Re: Active/operable shading help

Hi Jeremy

basically, you have two options: You can define up to three optical data property sets for a conventional TMC and switch between these via control (solar radiation for sure, zone temperature also, as far as I remember). How this is set up is described in the CookBook, I think. Alternatively, you can use CFC constructions for your windows and also control the shading (venetian type blind) setting for these (IMO the preferable path). However, the latter option has only a few control features to date in the official release version of ESP-r. But if you are willing to do a bit of coding and are set up to compile ESP-r, changes/extensions are quite straightforward (there is a pointer to where in the code changes are necessary in the list archive).

Betreff: [esp-r] Active/operable shading help

Hello,

I'm rather new to ESP-r and have been struggling to find a way to implement active/operable shading.  I want to put a feature in my model where the amount of shading over a window reacts to external parameters such as the outside temperature, inside temperature and solar radiation.  An example of active shading would be when the building is overheating, the shades will increase and block out the sun.  The opposite condition would exist when the building is cool and the Sun is shinning, the  amount of shading would decrease to allow more solar gains.  Does anyone know if this feature exists in ESP-r or how to make it work?

Currently I have several models with different level of shades and alternate models using bash scripts in Linux.  It's a quick fix but doesn't work the way I want.  Any help would be appreciated.

Jeremy
