Model For Analyzing Floorplate Morphology That Optimizes Daylighting And Cost, Andrew G. Welch, Ermal Shpuza Phd

The Kennesaw Journal of Undergraduate Research

One key method to improve the energy efficiency of a building is to enhance daylight levels, which reduces the need for artificial lighting. Elevated daylight levels are also associated with increased productivity and well-being of building occupants. Daylight levels are inversely proportional to the building compactness, where shallow floorplates and elongated buildings are associated with higher daylight levels. However, creating buildings that have more natural light comes with a greater construction cost due to larger envelope areas as well as greater operating costs due to the energy loss through the exterior envelope area. This research identifies the basic design strategies …
