I want the shades deployed whenever the outside air temperature is above room temperature (essentially summer only, never deployed in winter) AND (not OR) whenever the solar gain through the windows is greater than some value, high enough to only deploy the shades on a sunny day, but not so much on a cloudy day. The shades I’m considering only affect solar gain and have no significant effect on the U-value of the window. In reading through the reference literature, I think I need to enter a CONDUCT-TMAX-SCH (I have it set to 74F the entire year) and a MAX-SOLAR-SCH (I have it set to 20 Btuh/SF, but I would appreciate any feedback on a better number to use), both of which have to be satisfied to deploy the shades, and then a SHADING-SCHEDULE (the shade material being considered supposedly blocks 90% of the solar gain, so I have all hours set to 0.1) but no CONDUCT-SCHEDULE. My runs with these parameters show changes in energy consumption in winter months as well as summer months, so something obviously working as intended. I would appreciate anyone’s reply that has modeled similar shades and intents.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks in advance for your help,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Rick Routh<o:p></o:p></p><p class=MsoNormal>Routh Consulting Engineers, Inc., P.S.<o:p></o:p></p><p class=MsoNormal>P.O.
