If you see a reduction in heating load, the U-value used seems to be O.K. If you are using standard TMCs, "low e" or "argon" is only a name and does not have any real influence on the U-value. This is set by the resistance of the gap(s) between the panes of an IGU.</div><div><br></div><div>In the construction data base, you can see the U-value when you edit the construction, e.g. change the resistance of the gap. Also, you could check via QA report.</div><div><br></div><div>Best</div><div>Achim</div><div><br></div><div><br></div><div><br><div><div>On Jun 15, 2011, at 4:07 PM, <a href="mailto:A.Sdei@brighton.ac.uk">A.Sdei@brighton.ac.uk</a> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div lang="EN-GB" link="blue" vlink="purple"><div class="WordSection1" style="page: WordSection1; "><div style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0.0001pt; margin-left: 0cm; font-size: 11pt; font-family: Calibri, sans-serif; ">Dear All,<o:p></o:p></div><div style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0.0001pt; margin-left: 0cm; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0.0001pt; margin-left: 0cm; font-size: 11pt; font-family: Calibri, sans-serif; ">I am modelling some low-e + argon gas filled windows with esp-r. I change the database settings from ordinary double glazing to low-e + argon gas filled. The U-value increases from 2.8 to over 5. The results are fine (I can see a reduction of heating load) and I am curious to know what is going on there and if I can change the U-value. Does anyone know?
