| Abstract |
Factors which affect largely the economics of lighting system, are initial installation costs, maintenance costs, energy costs as so on. In these costs, maintenance costs are made up of lamp replacement cost, lamp replacement labor cost, luminaire cleaning cost et al. So the economics of lighting system are evaluated different by maintenance planning. It is important to evaluate which lighting system would be economically advantageous in a initial design. In this study, the importance of maintenance factor is verified by the evaluations of the economics of lighting systems while maintenance factor is varied composition factors in ZCM which is used to calculate the average illuminance. |
