Studies of solar access to the building envelope are key to effective daylighting and passive heating and cooling. Shading devices are not limited to awnings or light shelves. Partial overhangs, vertical shading fins, egg crating, brise‐soleils, pergolas, and so forth may be investigated given the range of BIM modeling characteristics. The designer can use building information modeling (BIM) to help evaluate the effectiveness of shading devices both to deny direct gain in warm months and to admit it in cold seasons. Since buildings are used year‐round, a rendering of shading conditions at a single moment in time is of limited usefulness. Solar animations are intended to overcome that limitation, and broadly include representational tools that depict the sun's movement over time—or more accurately the movement of shadows cast by the sun—whether over the span of a day, a season, or a year.
