Natural light and electrical light are totally different in Kahn’s idea. Even both of them are light. Kahn believe that Natural light is more lively and he also state that “A room is not a room without natural light” with his explanation : Every space must have natural light, because it is impossible to read the configurations of a space or shape by having only one or two ways of lighting it. Natural light enters the space released by the choice of construction.”
In The Kimbell Art Museum is a prime example of Kahn’s imaginative use of lighting where he developed a system that allowed natural light into the building but diffused it with a series of reflectors. These enhanced the galleries by bathing them in a silver glow but kept the light from directly touching the works of art.
In Esherick house Kahn bring dynamic into the house not by his the structural design. Instead of creating direct movement Kahn created a lot of opening to bringing in the sunlight as dynamic of the house. Because the natural light has very significant path during the way different shade during the day month and season enhance the building to be more lively with glow concrete wall. Kahn also state that “Also marvelous in a room is the light that comes through the windows of a room and that belongs to the room. The sun does not realize how beautiful it is until after a room is made. A man’s creation, the making of a room, is nothing short of a miracle. Just think, that a man can claim a slice of the sun.” to describe aesthetic of the house with natural light.
