SHADE & SHADOWS We use shade and shadows insite plans to convey the relative heights of building masses as well as to reveal the topographical nature of the ground planeon which t heshadows are cast. - --~-- ·· - - - ----- -------------------~ • The intent of cast shadows is not to render the actual condition of sunlight at a specific point intime. Rather, they merely indicate the relative heights of the parts o a building f above the ground plane. • Achange inshadow depth can indicate either an increase in building height or a rise in the ground slope. • Shade and shadows are not usually employed in floor plans and building sections. However, they may be used to emph asize thecut elements and the relative heights of objects withinthe space. • In abuilding section, shadows clarify the projection of cut elements beyond surfaces seen in elevation.
