As the internal loads are surely one of the most important factors for the calculation of cooling load – and at the same time one of the most “guessed” usually – making more realistic patterns usable for simulation is a step forward, surely. However, how do you see this in the context of dimensioning (of a building – U-value, g-value etc. – and of HVAC equipment)? Too many degrees of freedom may be contra-productive, here?   In regard to your second-to-last slide and the question on “what is the incidence angle behind the louvers”, my opinion is: -          the *incidence* angle is always in regard to the sun (sun azimuth and altitude in regard to the façade considered). For such louvers we could (a) model them individually in ESP-r as obstructions – if obstructions were enhanced with reflection and maybe even transmission (glass louvers are all ‘en vogue’, too) and in this way have direct-direct and direct-diffuse (and diffuse-diffuse, of course) transmission and reflection for the louver system / space behind or (b) model them as Venetian type blinds. Such a model could / will (?) then take direct-direct and direct-diffuse (and diffuse-diffuse, again) transmission / reflection into account for the space behind the louvers. -          if the interaction of ESP-r with Radiance could include “translation” of Radiance results to energy analysis for usage by ESP-r, the louvers would probably be no problem at all … maybe runtime, though.   <div> Best regards Achim Geissler   </div> <div style='border:none;border-left:solid blue 1.5pt;padding:0cm 0cm 0cm 4.0pt'> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: esp-r-bounces@lists.strath.ac.uk [mailto:esp-r-bounces@lists.strath.ac.uk] On Behalf Of Denis J.
