System” to the building external enclosure system as well. It could be easily under-
stood “Day-light System” can somehow be expressed by PI1 based on the weighted
factors of elevation, size, orientation, location, shading device type, and controls.
More complex performance indicators can be developed by relating more techni-
cal systems to one performance indicator for expressing one functional system as it
has been shown in Fig.

.
Here PI1 has been used to relate “Day-light System” to three technical systems
at once. These systems are exterior enclosure, neighborhood system, and interior
