What does 'aspect' refer to in urban planning?

The term 'aspect' in urban planning specifically refers to the direction a place faces in relation to the sun. This aspect can significantly influence various environmental factors such as sunlight exposure, energy efficiency, and the microclimates within a specific area, which in turn can affect the design and usage of urban spaces.

Understanding aspect is crucial for urban planners because it helps in optimizing natural light access, enhancing the livability of neighborhoods, and making decisions that promote sustainability. For example, buildings oriented to take advantage of sunlight can benefit from passive solar heating, reducing the need for artificial heating and cooling systems.

While height, layout, and construction materials are all important factors in urban planning, they do not capture the specific meaning of aspect as it relates to sunlight exposure and environmental orientation.
