<div dir="ltr"><div>Searched the archive but couldn't find an answer to this one:<br><br></div><div>What is the best strategy for modeling dynamic external window shading? We have an office building design in Europe with large south window exposure, and dynamic shading is a key part of reducing their cooling loads. In reality we have external horizontal blinds controlled on a solar irradiance value. <br><br>So far my best effort is the internal shading with a schedule, where schedule has a reset control based on outdoor DB being higher than cooling set point. <br><br></div><div>This is not giving realistic results, I think the heat is being dissipated into the interior space from these interior blinds. <br><br></div><div>Any successful modeling strategies to recommend? <br></div><div><br></div><div>Thanks,<br>Marcus<br></div><div><div>-- <br><span style="color:rgb(0,0,0)">Marcus Jones, </span><span style="color:rgb(0,0,0)"> M.Sc.</span><span style="color:rgb(0,0,0)">, </span><a style="color:rgb(0,0,0)" name="SafeHtmlFilter_131245b5df81718e__MailAutoSig"><span style="font-size:10pt"></span></a><span style="color:rgb(0,0,0)"><span style="font-size:10pt">LEED<sup>®</sup>AP BD+C</span></span><br style="color:rgb(0,0,0)"><i style="color:rgb(0,0,0)">Freelance energy consultant</i><br style="color:rgb(0,0,0)"><i style="color:rgb(0,0,0)">Vienna, Austria</i><br>
