<div>Felipe,</div> <div> </div> <div>these numbers show a very large differences. Diffrerences of lets say 30% could be explained by the different convection coefficients applied, supposing you implemented the same heat/cold emission system.</div> <div>There must be some more differences in your input file.</div> <div>Maybe start by performing a simple test calculating the thermal loads of a cubic sealed (no ventilation) box without windows and without internal gains. Then see whether such large differences occur for that case also.</div> <div> </div> <div>Keep us in touch, so we could try finding out with you .;..</div> <div> </div> <div>Succes</div> <div> </div> <div>Leen Peeters<br><br></div> <div class="gmail_quote">2009/9/8 Felipe Durán <span dir="ltr"><<a href="mailto:felipe@b-green.cl">felipe@b-green.cl</a>></span><br> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> <div style="WORD-WRAP: break-word">Dear All, <div><br></div> <div>I am modeling in both ESP-r and IES-VE and office building and the results for heating and cooling loads are very different. </div> <div><br></div> <div>ESP-r = 269 kW (heating); 237 kW (cooling)</div> <div>IES-VE = 835 kW (Heating); 360 kW (cooling)</div> <div><font size="3"><span style="FONT-SIZE: 12px"><br></span></font></div> <div> <div><span style="WHITE-SPACE: pre; BORDER-COLLAPSE: collapse"><font size="3"><span style="FONT-SIZE: 12px">Does anyone had a similar experience with such differences?</span></font></span></div> <div><br></div></div> <div>Kind Regards,</div> <div><br></div> <div><br> <div><span style="WORD-SPACING: 0px; FONT: 12px 'Century Gothic'; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; WHITE-SPACE: normal; LETTER-SPACING: normal; BORDER-COLLAPSE: separate"><span style="WORD-SPACING: 0px; FONT: 12px 'Century Gothic'; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; WHITE-SPACE: normal; LETTER-SPACING: normal; BORDER-COLLAPSE: separate"><span style="WORD-SPACING: 0px; FONT: 12px 'Century Gothic'; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; WHITE-SPACE: normal; LETTER-SPACING: normal; BORDER-COLLAPSE: separate"><span style="WORD-SPACING: 0px; FONT: 12px 'Century Gothic'; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; WHITE-SPACE: normal; LETTER-SPACING: normal; BORDER-COLLAPSE: separate"><span style="WORD-SPACING: 0px; FONT: 12px 'Century Gothic'; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; WHITE-SPACE: normal; LETTER-SPACING: normal; BORDER-COLLAPSE: separate"><span style="WORD-SPACING: 0px; FONT: 12px 'Century Gothic'; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; WHITE-SPACE: normal; LETTER-SPACING: normal; BORDER-COLLAPSE: separate"> <div><span style="FONT-WEIGHT: bold">Felipe Durán Palma</span></div> <div>Arquitecto PUC, MPhil.
