Before a single line gets drawn on a site plan, you need to understand three invisible forces shaping every design decision: where the sun travels, how wind moves across the property, and what views matter. Environmental analysis diagrams translate these forces into graphic tools architects use during programming and site analysis. Getting comfortable reading these diagrams is one of the most practical skills you'll carry into practice.

Sun path diagrams map the sun's arc across the sky at different times of year, giving you solar altitude and azimuth angles that drive decisions about glazing placement, shading devices, and building orientation. Wind rose diagrams summarize prevailing wind direction and speed data, telling you where to capture breezes for natural ventilation or where to block cold winter gusts. View corridor studies identify sight lines worth preserving or screening, connecting the site to its larger visual and spatial context.

On the ARE, you won't just identify these diagrams. You'll evaluate what they communicate about site conditions and relationships, then connect that information to programming requirements and design responses. Objective 3.3 tests your ability to analyze graphical representations, so expect questions requiring you to read a diagram, make a judgment about how it affects site layout or building placement, and resolve conflicts when multiple diagrams push the design in different directions.
