Maybe an obstruction pattern with reduced area such that transmission is equivalent is easier (however, the max number of obstructions may be limiting). 2) Why is tracking solar to high detail important for the analysis? If it is daylight, then coupling with Radiance would come to mind (obstructions for the “energy” calcs done by ESP-r, actual glazing for the daylight calcs done by Radiance).<o:p></o:p> <o:p> </o:p> Regards<o:p></o:p> Achim<o:p></o:p> <o:p> </o:p> <o:p> </o:p> <div> <div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'> From: Tang, David [mailto:David.Tang@owenscorning.com] Sent: Montag, 24.
