Beyond solar orientation, a regenerative site analysis considers the full system of flows and conditions that will affect the building and its occupants. The following factors should be assessed for every site before design begins. **Topography** Slope, aspect (which direction the slope faces), and elevation all affect solar access, wind exposure, drainage, and buildability. South-facing slopes in the northern hemisphere receive more solar radiation and are warmer than flat ground or north-facing slopes. Ridge tops are windier. Valley bottoms accumulate cold air at night. Understanding topography allows you to position the building and its systems optimally within the landscape. **Hydrology** Where does water come from, where does it go, and how much is there? Map existing drainage patterns, identify ephemeral and permanent water bodies, and understand the site’s relationship to its watershed. This analysis informs both the placement of the building (avoid flood paths) and the design of water harvesting…
