<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt"><div>Dear TRNSYS users,</div><div><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: times new roman,new york,times,serif; background-color: transparent; font-style: normal;">I'm using TNSYS3D plugin to create a model for my house. I created the thermal zones and now I have to add the shading groups. <br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: times new roman,new york,times,serif; background-color: transparent; font-style: normal;">The house has only external windows in very thick outside walls. For some of the zones, even if the sun shines on the outside wall, little light enters the zones. So I have to take into account the self-building shading due to the thickness of the walls.</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: times new roman,new
york,times,serif; background-color: transparent; font-style: normal;">Is it OK if I draw very thin wing walls around the external windows?</div></div></body></html>
