Well, Ecotect is a pretty good and user-friendly software especially at initial design stage to my mind. It is able to provide sort of "laymen' language among energy modeler and other consultants, owners, etc. For your particular questions, see my two cents below. Hope they are helpful. <br clear="all">

<div>Hi,</div>
<div> </div>
<div>Can day-lighting analysis be done in Ecotect for a Sketch-Up .dxf file as well?</div><div> </div></font><font color="#3333ff">It is possible. However, pay attention to the imported model where some oringinally planar surfaces become unplanar and you have to address these places.</font> <font color="#3333ff">On the other hand, it is not necessary to import the whole model when you are going to analyze particular windows/openings (unless the building itself will have self-shading impact over your target windows) </font></div>

<div>When importing a 3-d model in Ecotect, the whole model comes as 1 zone. When I select for Lighting Analysis, the analysis grid is of irregular shape even after selecting <i><b>with</b></i><i><b>in</b></i> option in window fit grid extents. Does this depend
on simplicity of model?</div><div> </div></font><font color="#000099"><font color="#3333ff">1 zone is okay for lighting analysis though it will definately affect your thermal analysis. And yes, as I mentioned, pay attention to some unplanar surfaces. Alternatively, you can draw and replace your target windows/openings within Ecotect yourself. Sometimes, it is not easy to modify the existing model due to converion issues caused in the process. </font> </font> </div>

<div>How successful is shading design? Usually it results in extraordinarily big sun-shades.</div>
<div> </div><div><font color="#3333ff">Bear in mind, those big and irregular sun-shades is not for your design dimension but a guide or verificaiton for your proposed design. remember it is a best-case scenario.</font> </div>
