Marco your results sound very interesting, and very much in line with my experience. But this goes in some contradiction with Achim’s comment about triple glazing performing better, which is also a valid point (thanks Achim). Our results show a benefit in surface temperature if you go for external shading but have not used ESP-r for this and wondered if it is a modelling issue. This is for a building in <st1:City w:st="on"><st1:place w:st="on">Dubai</st1:place></st1:City>. Is there any chance I can see some results of your study? <o:p></o:p> <o:p> </o:p> Regards<o:p></o:p> Camilo<o:p></o:p> <o:p> </o:p> <o:p> </o:p> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: <st1:PersonName w:st="on">esp-r-bounces@lists.strath.ac.uk</st1:PersonName> [mailto:<st1:PersonName w:st="on">esp-r-bounces@lists.strath.ac.uk</st1:PersonName>] On Behalf Of Marco Manzan Sent: 20 April 2009 13:57 To: <st1:PersonName w:st="on">esp-r@lists.strath.ac.uk</st1:PersonName> Subject: [esp-r] Re: Obstructions<o:p></o:p> </div> <o:p> </o:p> > Date: Sun, 19 Apr 2009 13:22:59 +0100<o:p></o:p> > From: "Diaz, Camilo" <Camilo.Diaz@WSPGroup.com><o:p></o:p> > Subject: [esp-r] Re: Obstructions<o:p></o:p> > To: <<st1:PersonName w:st="on">esp-r@lists.strath.ac.uk</st1:PersonName>><o:p></o:p> > Message-ID:<o:p></o:p> > <C7F7A047EE606843AA7A33EF3EAD540C0196B849@exc01col1uk.uk.wspgroup.com><o:p></o:p> > Content-Type: text/plain; charset="utf-8"<o:p></o:p> ><o:p> </o:p> > Dear all, a separate but related issue.

I'm comparing standard double glass and selective glass with low g value. I'm considering heating, cooling and lighting . What I found is that a optimized shading device coupled with double glass behaves better than an high performance glass with or without shading devices. For the moment the results are for a south exposed window and norther <st1:country-region w:st="on"><st1:place w:st="on">italy</st1:place></st1:country-region> climate. <o:p></o:p> -- <o:p></o:p> _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ <o:p></o:p> |Marco Manzan Email: manzan@units.it | <o:p></o:p> |Tel: (+39) 040 5583506 Fax : (+39) 040 572033 | <o:p></o:p> |Dipartimento di <st1:place w:st="on"><st1:City w:st="on">Ingegneria Navale</st1:City>, <st1:State w:st="on">del</st1:State></st1:place> Mare e per l'Ambiente | <o:p></o:p> |Universita' degli Studi di Trieste | <o:p></o:p> |piazzale Europa 1, 34127 <st1:City w:st="on"><st1:place w:st="on">TRIESTE</st1:place></st1:City> | <o:p></o:p> |_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _|<o:p></o:p> </div> </body> </html>
