Seasonal solar exposure across courtyard geometries
A full solar-year analysis examines latitude, orientation, wall height and plan proportions through monthly and seasonal transmission.

Solar geometry
How do orientation, proportions and wall height govern the path of direct sunlight through a built space?
Scientific scope
The question we pursue.
We connect exact instantaneous shadow overlap with solar trajectories over a generic non-leap year. The programme resolves direct exposure by month and season, separating geometric effects from meteorological variation.
Our present system is an unobstructed rectangular opening above a horizontal floor, enclosed by opaque walls. The published analyses use established physical relationships to isolate and quantify their consequences.

Courtyard geometry and direct sunlight
The foundational analytical study isolates direct sunlit floor area at specified solar elevations and azimuths, with an interactive model.

A common reproducible framework.
All studies use a fixed 100 m² floor area so aspect-ratio effects can be compared consistently. Geometry, numerical resolution and units are explicit in the datasets.
The data and software catalogue provides complete numerical tables and source. Research practice sets out attribution, versioning and corrections.
Scientific responsibility
Osama Khaled directs the programme’s scientific questions and decisions. Methods, modelling, verification and data responsibilities are described in the team directory.
