(incident radiation during the year in a building in Madrid - iaakuza)

In the last post, I wrote that one of the weak points of the shadow-range is the fact that tool doesn't take in consideration the intensity of the radiation: in other words, you know which parts are more shadowed but you don't know how much incident/diffuse radiation gets the surface of th building. Another tool of Ecotect (you might do the same in Radiance, of course) is solar access analysis. Solar access refers to the availability of incident solar radiation (insolation) on points and surfaces within your model. You need to upload a weather file that contains data about solar rdiation. Everything is ready: upload the weather data, and import the 3d file (.3ds). Now you might need to subdivide the surface (if you surface is complex or cilindric...). Select the surface you want to split and Modify---> Surface subdivision ---> Rectangular tiles ---> choose the dimension of the tile ---> tick the option "trim tiles to fit ..." and "delete...".
It is time to talk about radiation: Select the surface you need to analyse, Calculate ---> click on incident sola radiation ( if you are not sure about the materials) ---> choose the period and the time range ---> choose between the total sum of all values, their average or the maximum value of each metric on each point or surface ---> tick "Performed detailed..." ----> run the calculation!
On your surface, you might see dots and numbers: click on Display setting ----> tick show color in object attribute and set the legend colour. Got it!
