SUN ACCESSIBILITY VS BUILDING HEIGHT MAPPING

Digital Tool for Urban Analysis

An exercise of mapping the sunlight access on the streets dominated by the streetscape is generated through reflecting the relations between the building heights and the amount of sun light that is captured on all surfaces in one day. The relations are expressed through comparison through curves, colors and solids. The specific site picked for this exercise is the Financial District of New York City, and the weather data are collected from New York State data website.

The intention of this exercise is to be able to expand the time scope from a day to a week, a month, a year or a decade, and applied to all different locations and cities for comparison. The visualization tends to appear comprehensive and legible. Eventually, it could become a design tool for urban designers and architects to understand the most effective urban configurations for a healthy urban environment.
