Dear all, I have some doubts about shading. Looking at the attached (that is a plant of the thermal zone subject of my study), you can see that there are portions of wall (indicated by letters) that, depending on the sun direction (e.g. north or north-west in my case), cause a shadow zone on the walls indicated by numbers. In consequence of this, walls indicated by numbers shouldn't have the same amount of solar radiation incident on their outside surface. Am I wrong if I think so? Is this shading important for the calculation of the incoming and outgoing heat from each wall and for the calculation of heat and cooling demands? In this case,maybe I should indicate separately every portion of wall indicated by numbers and letters so that I can take into account these shadings by an appropriate value of geosurf for each portion of wall or can I alternatively take into account these shadings in some other way? For example, can I use types 34, 64 or 67 for my purpose? Thanks in advance for any help. Best regards, Davide. |
