<HTML><BODY>   Dear Daisy   what you would need to do is the following: 1) Shading coefficient refers to "behaviour in regard to solar gains", not visible transmission. You take your shading coefficient and from this calculate the SHGC (or g-value). See ASHRAE Fundamentals, e.g. 2) You choose a glass product that achieves this g-value in Window (LBNL). Here, you can check if you can find a glass product that also satisfies your visual transmittance needs. 3) With this glass product you set up your insulating glazing unit in Window and export (by whatever path you are comfortable with) to ESP-r TMC or via GSLEdit to CFC.   Best Achim --------- Original-Nachricht -------- Von: "Íõ¾Õ»¨" <luckygrass100@hotmail.com> An: "esp-r@lists.strath.ac.uk" <esp-r@lists.strath.ac.uk> Betreff: [esp-r] Shading vs visible transmission Datum: 29/04/10 07:06  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 mul! tiply 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. <hr />ËÑË÷±¾Ó¦ÊÇ²ÊÉ«µÄ,¿ìÀ´ÌåÑéÐÂÒ»´úËÑË÷ÒýÇæ-±ØÓ¦,¾«ÃÀÍ¼Æ¬Ã¿Ìì»»Å¶! <a href="http://cn.bing.com/?form=CRMADS" target="_new">Á¢¼´ÊÔÓÃ£¡</a> <hr /> _______________________________________________ esp-r mailing list <a href="mailto:esp-r@lists.strath.ac.uk" class="autolink">esp-r@lists.strath.ac.uk</a> <a href="http://lists.strath.ac.uk/mailman/listinfo/esp-r" target="_blank" class="autolink">http://lists.strath.ac.uk/mailman/listinfo/esp-r</a> ________________________________________________________________<BR! >Diese Mitteilung wurde von http://www.breitband.ch uebermittelt.
