The variation of daylight levels across atrium walls: Reflectance distribution and well geometry effects under overcast sky conditions
Daylight plays a major role in making atrium spaces appealing to building users. This appeal is also evident in the spaces adjoining the atrium. A key component of atrium daylighting, especially in tall atria, is the daylight reflected on to the atrium walls. This study examines the impacts of well geometries and different diffuse reflectance distributions of walls on variations of vertical intern
