Hi chris, I am doing a shading study under skylights for a big roof.
I set up comfort autonomy definition from hydrashare, and want to find out comfort levels.
-
I am looking at radiant temperature. what is the default material (default floor) and how to change?
-
for the radiant temperature what is too much? any information or standard about this for people waiting in line? for what I am studying, the result air temperature is 28 but all tiles are returning overheated. the purpose of this study is to see if current baseline design of skylight and louvers are adaquate for thermal comfort.
-
for louvers, i understand that you can either a choose custom geometry but cannot change reflectance, or use windowshade generator but can’t do custom gemetry. has there been a work around for this? and if I had louver material to aluminium, could this effect thermal comfort significantly?
-
I am thinking i need to plugin in shade geometr for both exportToOpenStudio and IndoorViewFactor (talking about louvers under skylights). its taking very very long to add louvers to the definition. what the fastest and roughly accurate way to model and input louvers in this case?
-
I read here that one can use lightshelf to change material for shades.(here)
if i use SHDdesign for louvers to both exportToOpenStudio and IndoorViewFactor, will the reflectivity be reflected in the calculation? -
and for the raidant temperature, if I set analysis period for a month, does it take an averange of all hours for each tile? I guess i didn’t understand why the radiant temperature is so high if I did 24 hour cycles. (result ranging from 45-70 degrees celcius). There must be an error because i am getting really high temperatures at night…?
Thank you !!
