The lighting scheme consists of two parts: typical task lighting particular to the program of each zone, and general lighting provided by the shelter of the L-module. The general lighting is in a regular pattern with no definition of spaces, allowing for flexibility of any infill architecture configuration. The color temperature and light level are automatically determined by exterior environmental conditions. The intent is to reduce the amount of energy typically needed to condition the interior by psychologically affecting the space. A hot summer day might bring the color temperature of the general lighting toward the cooler end of the spectrum, thereby making the inhabitants feel cooler, and thereby ultimately requiring less energy for air conditioning.
