each technical system has been related to the factors which have direct effect on
how the specifi c technical system can perform.
It can be seen that a few good performance indicators can be developed to
represent the “Day-light System.” For example PI3 relates the “Day-light System”
to the building artifi cial lighting system. It could be easily understood that “Day-
light System” can somehow be expressed by PI3 based on the weighted factors of
controls, type and location of the light fi xtures. Also PI1 relates the “Day-light
