<div dir="ltr">This is an interesting question, I have never tried to output an entire grid of illuminance levels in a space from eQuest. (Can it do that? Now I'm intrigued) <div><br></div><div>But even assuming it can, looking into the language of the LEED v4 credit, I don't think you can use eQuest illluminance calcs to demonstrate compliance. <div><div><br></div><div>LEED v4 simulation option requires that you calculate illuminance for direct sun as well as sky. But the calculations within eQuest (and EnergyPlus for that matter) are basically just daylight factor, so it calculates an average window luminance based on sky luminance etc., and then uses that to calculate illuminance at each point. It does not calculate direct illuminance at a point from beams of sunlight in the way that ray-tracing methods (like Radiance) or radiosity methods (like AGI32) can, so I'm thinking it does not meet the credit simulation requirements.</div><div><br></div><div>I'm not sure you could even use it to check whether the project as a whole could potentially comply or not, since limiting direct sunlight (target is 300-3000 lux) at each calc point is such a big part of compliance. But, eQuest would probably give a decent assessment of illuminance in simple, non-convex <u>north facing</u> spaces, since that is only sky component -- and if those spaces knock you out of the running for compliance, then you know you don't need to worry about the rest.<br></div><div><br></div><div>Cheers,</div><div>Elizabeth</div></div></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><b><br></b></div><div dir="ltr"><b>Elizabeth Gillmor <font size="1">PE, BEMP, LC, LEED AP</font></b><div><br></div><div><span style="font-size:large;background-color:rgb(255,255,255)"><b><font color="#38761d" face="arial, helvetica, sans-serif">e n e r g e t i c s </font></b></span><b><font color="#38761d" face="arial, helvetica, sans-serif" size="2">consulting engineers, llc</font></b></div><div><font size="2" style="background-color:rgb(255,255,255)" color="#666666"><a href="http://energetics-eng.com" target="_blank">energetics-eng.com</a> |</font><span style="color:rgb(102,102,102);font-size:small"> 303.619.0091</span></div></div></div></div></div></div></div></div></div></div></div></div></div>
