Architectural The building shown will be used to study passive solar heating at different times of the year. Model the building using the overall dimensions given. Use your own dimensions for everything else. The side with the windows should be facing South (–Y in AutoCAD, by default). A. Set the geographic location to a city in the northern hemisphere. B. Set the date to midsummer and the time to noon. C. Turn on sunlight and turn the default lighting off. D. Render the scene and note the location of the shadows inside the building. E. Change the date to late winter, render the scene again, and note the new loca- tion of the shadows. You can easily switch between the rendered images in the Render window by selecting each rendering in the history and statistics pane (this is discussed more in the next chapter). F. Observing the changes in the shadow locations, what design changes can be made to maximize sun exposure in the cold winter months? What design changes can be made to minimize sun exposure in the heat of summer? G. Change the geographic location to somewhere closer to the equator. Then, render the scene in summer and winter. How do the shadows compare to those in the previous location? H. Save the drawing as P18-4. 35’ 20’ 10’ 21’ A full-color image is provided on the companion website. www.g-wlearning.com/CAD/
