These shading devices, if appropriate, can be modeled as adding differently to the daytime and nighttime insulative properties of the glazed opening. They can be controlled with simple time schedules (which could be the same schedules as for lighting) and/or according to a specified threshold of incident solar radiation and/or in keeping with formula profiles that reference the same parameters as the HVAC controls (room temperature, outdoor weather variables, etc.) or even the results from daylight sensors used for dimming interior lights. Thus the louvers could be controlled by the same inputs as the HVAC system.</SPAN><SPAN style="FONT-SIZE: 12pt; COLOR: blue; FONT-FAMILY: 'Times New Roman','serif'; mso-bidi-font-weight: bold; mso-fareast-language: EN-US"><o:p></o:p></SPAN></P>

<P class=MsoNormal><FONT face="Century Gothic" color=black size=2><SPAN style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: 'Century Gothic'">I’m working on a study. It is about the dynamic facades (building automation) . One of the façade feature which I’m trying to test is the automated louvers which has a control which is connected to the HVAC and lighting system. I am trying to test this feature in a certain weather. Does anybody know an energy simulation tool that can make such simulations? Due to my architectural background, I would prefer if it is a graphic user friendly interface to a simulation engine.</SPAN></FONT></P>
