He also stated “light is the key to well-being” and further
“I compose with light.”
To effectively use natural light, first assess its availability.
The quantity and quality of light available for illumination in a building are determined by the regional climatic conditions.
Available daylight patterns are modified by factors such as adjacent landforms, vegetation, and structures. The varying light conditions create dramatically different perceptual environments and architectural responses.
The three basic sources of natural light are:
For all lighting designs, the primary goal is to provide illumination for visual activities and visual delight. With sunlight, the basic design strategy is to use the sunlight indirectly. Indirect use of sunlight addresses the initial difficulty of a moving source of extremely high candlepower.
The building design should admit the proper amount of sunlight, use it efficiently, and redirect it for balanced illumination and to avoid glare.
The most obvious trait of modern architecture is its permeability to daylight. Instead of blocking out most incident light, as did solid walls with small windows in the past, the new skeletal volumes are widely but also deeply porous to natural illumination.
Even by the end of the 19th century, a startling change can be detected in the admission of daylight to buildings. As the proportion of openings to solid material began to reverse and then widen dramatically, interiors were flooded with fluctuating moods of weather and sky. Instead of enclosing space with massive walls, the building envelope became a filter to transmit inside a magical radiance.
