Mixed Life Cycle-Cost Benefit Web Based-Decision Tool for Lighting Load Retrofitting and Management

This paper presents a prototype of web based interactive application that has been developed as a decision tool in
lighting retrofitting and its loading management. The main purpose of the application is to support Lighting-Demand Side
Management program. Life cycle cost method and cost-benefit analysis are both used as financial basis to obtain the best
option among selected alternatives, which has the least life cycle cost and the highest net present value that reflect cost-benefit analysis result. An interactive daily lighting loading curve that can be constructed based on several scenarios of lighting utilization is available. This web application, of which accessible online and offline, is developed using Hyper Text Markup Language 5, Cascading Style Sheets, and JavaScript programming.
