In this article, the author talks about legibility as an essential component of education facility design. Legibility is concerned not only with stylistic consistency, but also with other design factors that help make a building understandable. Reconfigured interiors and multiple additions can create confusing paths. Illogical assortments of materials, finishes and colors compound the confusion. Rambling networks of corridors, stairways, and spaces arranged without clear hierarchies are difficult to comprehend. Outside awareness--looking through windows that provide views to the outside--is another factor in legibility. A view of the outside helps orient people within a building, and absence of outside awareness can confuse them quickly. Using single-loaded corridors with windows on one side and using windows at important places are common ways to provide outside awareness.
