With less conduction, a smaller cooling load will normally decrease cooling energy.</div><div class="gmail_default" style="font-size:large;color:#000000"><br></div><div class="gmail_default" style="font-size:large;color:#000000">An exception to this is when internal loads are higher than normal. In that case, the building needs to get rid of internal heat (provide cooling) most of the year. When the envelope has more insulation (lower U-value), it inhibits heat removal and can increase cooling energy.</div><div class="gmail_default" style="font-size:large;color:#000000"><br></div><div class="gmail_default" style="font-size:large;color:#000000">Thanks to my friend Javed Iqbal for reminding me of this recently. He is preparing a paper which discusses this phenomenon for buildings in the central European climate.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Nov 3, 2017 at 8:37 AM, akshay gupta via Bldg-sim <span dir="ltr"><<a href="mailto:bldg-sim@lists.onebuilding.org" target="_blank">bldg-sim@lists.onebuilding.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi There<div><br></div><div>I am facing an issue in eQuest in almost all simulation models for most hot and composite indian climates.
