The U-value of the glass is approximated by adapting the thermal resistance of the glazing gap air.   - the external emissivity of the double glass (pos. 1 and 4) actually used in the simulation can be checked in the construction file (.con):   # for each surface: inside face emissivity  0.22000,0.99000,0.22000,0.99000,0.90000,0.90000,0.22000 # for each surface: outside face emissivity  0.22000,0.83700,0.22000,0.99000,0.90000,0.90000,0.22000   (where ※surface§ actually should read ※construction§).   My experience is that if the correct value is set here, there are feasible differences in the calculation results.   Regards, Achim     <div>     </div> <div style='border:none;border-left:solid blue 1.5pt;padding:0cm 0cm 0cm 4.0pt'> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: esp-r-bounces@lists.strath.ac.uk [mailto:esp-r-bounces@lists.strath.ac.uk] On Behalf Of ????

But, I find out the result that can't understand. The result of surface temperature is the very same case1 and case4, case2 and case3. guess that ESP-r program appear number函 value of emissivity int and number刷 value of emissivity ext  regardless of glass. Please, solve the problem. Thank you.   Sincerely Young-Sub An --------------------------------------------------------------------------------------- Case 1. -> Low-e coating is applied to number刷 of glass surface. Case 2. -> Low-e coating is applied to number券 of glass surface.         To apply on number券 of glass surface changes the emissivity value. Case 3. -> Low-e coating is applied to number函 of glass surface.         To apply on number函 of glass surface inverts glass(dlow24) of case 1. Case 4. -> Low-e coating is applied to number刻 of glass surface.         To apply on number刻 of glass surface changes the emissivity value.    <img width=32 height=32 src="file:///F:\esp-r%20question\Case1,%202.jpg" align=baseline border=0> <img width=32 height=32 src="file:///F:\esp-r%20question\Case3,%204.jpg" align=baseline border=0> </div> </td> </tr> </table> </div>  (*^^*) ---------------------------------ooO--U--Ooo----- 寰艙撥 305-719 渠瞪嶸撩掘湯貲翕骯 16-1廓雖措董フ寧渠ピ掖 勒蹴奢ピ婁 1翕 313龱勒蹴�唳/啗�/撲綠翱掘褒 Tel : 042 821-1636 Mobil : 010-3002-0184 E-mail : rnsqks8646@hanmail.net Homepage : http://hyunam.hanbat.ac.kr/~jhyoon -----------------------------------ooO-Ooo-------  <div style='margin-top:15.0pt;background-position-x:0in;background-position-y: 0in' id=mailFooter> <div id=mfTop> "辦葬檣攪喘, Daum" <a href="http://www.daum.net" target="_top">http://www.daum.net</a> ◇が儅噙朝鼠猿フ詭橾喘◆ </div> <div style='border:solid #DFDFDF 1.0pt;padding:0cm 0cm 0cm 0cm;margin-right: 9.0pt;margin-bottom:7.5pt;float:left' id=mfLeft> <a href="http://allim.daum.net/servlet/Redirect?sid=footer060925_daumdirect" target="_new"><img border=0 width=350 height=48 src="http://hmm.daum.net/image/daumdirect_hanmailfoot.gif"></a> </div> <div style='border:solid #DFDFDF 1.0pt;padding:0cm 0cm 0cm 0cm;float:left' id=mfRight> <a href="http://allim.daum.net/servlet/Redirect?sid=footer_lucky1204" target=new><img border=0 width=350 height=48 src="http://mailimg.hanmail.net/event/061129_hm3/footbn_061129.gif"></a> </div> </div> <img border=0 width=32 height=32 src="http://wwl534.hanmail.net:4280/@from=rnsqks8646&rcpt=esp%2Dr%40lists%2Estrath%2Eac%2Euk&msgid=%3C20061210201159%2EHM%2E000000000002YAG%40rnsqks8646%2Ewwl534%2Ehanmail%2Enet%3E"> </div> </div> </body> </html>
