Skyfacing

Skyfacing is the orientation of an object, surface, or approach toward the sky. The term is used in several disciplines to describe a directionally upward focus, distinguishing elements that are exposed to the open sky from those blocked by surrounding structures or terrain.

In architecture and urban design, skyfacing surfaces include skylights, clerestory windows, and roof planes designed to maximize daylight and sky visibility. The concept is closely tied to daylighting strategies and to the measurement of sky exposure, often quantified by the sky view factor, which estimates how much of the sky is visible from a given point inside a building. Skyfacing openings can improve natural illumination, reduce artificial lighting needs, and influence thermal comfort, though they may affect solar gain and weather exposure.

In landscape, sculpture, or product design, skyfacing can describe the orientation of an installation intended to be viewed against the backdrop of the sky, or a surface designed to reflect or interact with the sky, such as reflective panels or solar collectors.

In photography and meteorology, the term may describe shots or measurements oriented toward the sky, such as upward-facing cameras or instruments that monitor atmospheric conditions.
