Light work challenges in implementing lighting control sytems

摘要

Bernard's project began as a final year thesis for the Honours Degree in Electrical Services and Energy Management in DIT, Kevin Street and he set out initially to do a post-occupancy evaluation of lighting controls installed in a range of buildings, including a public office building, a shopping centre and a primary school. Actual controlled lighting consumption was to be compared against past billing or simulated energy consumption. When the research began, it was found that the controls had been removed from two of the three buildings. It became apparent that disconnection was not untypical and although considerable research has been conducted into a comparison of control types, little research was available to account for failures of lighting control systems. Documented evidence of failed systems is also a rarity. At the same time, the use of lighting control systems is becoming more relevant as energy consumption, energy costs and greenhouse emissions are pushed to the forefront of our economic agenda. This raised a bigger research question as to why were the controls disconnected and what factors govern the success or failure of these systems?
