Have you done a simple calculation "DT * U" for both and compared these? Also, the first four cm of insulation is the most effective. So, your 40% reduction need not be totally off.</div><div><br></div><div>Best</div><div>Achim</div><div><br></div><div><br></div><div><br><div><div>On May 2, 2011, at 4:35 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 experiencing a problem with ESP-r that seem to have no solution at the moment. I would like to ask you to please help, I am modelling a solid floor and by using the monthly ground profile for the boundary condition of the floor ESP-r gives me unrealistic results for the heat loss (the heat loss through the ground floor is double the heat loss through the ceiling). Moreover, if I insulate the ground floor with 4 centimetres of EPS, the heating load is cut by 40% which is even more unrealistic. I have tried with the BASESIMP method but it does not seem to work.
