This is in fact one of the first observations I made and communicated to Mats. The rationale for excluding it - apart from 'you can buy our core software suite' - was that the sun is all over the place - so why would you consider it in an hourly analysis. Mats - please use your own words if you read this - but I tried to explain, that it is all over the place in a predicatble way, and we specifically model our buildings to block the sun at the times of year when incident heat gain is worst - and we use the AC and/or Artlantis heliodon to verify these conditions/fin designs in QT movies. That a connection to the AC Heliodon was ignored 'for now' seems like a real wasted opportunity. Designers NEED to understand the effect architectural shading elements have on the building - whether they are part of the building or adjacent conditions! Unintended shading limits passive solar gain in winter, and can lead to uncomfortable spikes in the cooling season - things designers need to know. There is really no point in bragging that ED has an 'hourly step' analysis if the incredibly simplified report won't tell me that the living room climbs to 120degF on June 21 at 4pm - does it?!
