Natural grass stadiums depend on a precise relationship between daylight, geography, building orientation, and roof geometry. In enclosed or partially enclosed stadiums, the ability of a playing field to support healthy grass growth is shaped by solar access, seasonal variation, latitude, climate, and the design of openings such as an oculus. As stadiums become more architecturally complex, daylighting analysis becomes essential to determining whether a non-retractable grass field can perform without compromising the spatial and experiential goals of the venue.

This framework establishes a daylight-driven approach to stadium siting, orientation, and oculus design. The framework must:

1. Evaluate potential stadium sites around the world based on daylighting conditions, solar exposure, and geographic performance;

2. Determine the feasibility of maintaining a non-retractable natural grass playing field within different stadium configurations;

3. Optimize stadium orientation, roof form, and oculus geometry to maximize daylight access and improve grass growth capability;

4. Analyze existing stadiums and projects in schematic or design development phases to identify strategies for enhancing field performance.
