[esp-r] Re: Shading vs visible transmission

[Lomanowski, Bartosz]

Dear Daisy,
 
You may wish to explore the Complex Fenestration Construction facility in ESP-r in order to model windows with operable venetian blinds. You will have to download GSLedit, a small glazing/shading assembly editor used to set up the input parameters for ESP-r CFCs. It is available here: http://www.esru.strath.ac.uk/Downloads/downloads.htm#ESP-r <http://www.esru.strath.ac.uk/Downloads/downloads.htm#ESP-r> 
 
Appendix F of my thesis on this subject contains a user's manual which you may find helpful. You can find it here:

There is also a control facility found in prj under 'Controls: complex fenestration' that allows you to manipulate the slat angle and the shade layer state (retracted/deployed) as a function of a sensor/actuator combination or a schedule. 
 
The CFC facility was originally intended for energy/load analysis and is currently missing daylighting features. You can also try programs such as WIS and WINDOW 6 to calculate performance indicies of glazing/shading combinations.

Dear all,

     I have a question since I began to learn esp-r.There was an article called "Setting Shading Coefficient for transparent constructions and double facade" posed by my friend Teresa.Jon Hand kindly gave answer that  ESP-r does not use a "shading coefficient" which is a ratio of a specific glazing product to a 'standard single glazed window'.Please allow me to ask further,what should I do if I want to set a Shading Coefficient,for example,0.57?for the south window.I tried to multiply the visible transmission of window by 0.57.But when I output results of dynamic load,there is no change compared with the actural visible transmission condition.I am thinking whether changing visible transmission just influences lighting analysis results.

     I really don't know how to add  electric shading  louvers for windows to reach a required Shading Coefficient of 0.57.I am using esp-r for energy simulation of a green low carbon building.Anxiously looking forward to your kind answers.Many thanks.Daisy.
