Daylighting In Buildings: Investigating The Relationship Between Daylight Levels And Building Compactness In Various Contemporary Architectural Types. [Efficient Typology Classification], Andrew Welch, Ermal Shpuza Phd

Symposium of Student Scholars

One of the key ways of improving the energy efficiency of a building is to enhance the daylight levels and reduce the need for artificial lighting. Good daylight levels are also associated with increased productivity and the well-being of a building's occupants. Daylight levels are often a direct function of the floorplate depth, where locations near the windows receive more daylight, and those deep inside the buildings receive less. As a result, shallow floorplates and elongated buildings are usually related to higher daylight levels. However, shallow buildings that have more natural light are also associated with greater construction costs due …
