EFFECTIVE LIGHTING MANAGEMENT IN KHOO TECK PUAT HOSPITAL (KTPH)

Abstract

In recent years, the construction of green buildings is gaining emphasis globally. Reasons for such may be due to the problems of global warming and raising energy cost. Consequently, it calls for the need of energy management within buildings, to add value to the global energy efficient buildings landscape through good building designs and efficient in-house management.

The nature of hospital’s continuous operation results in a higher energy consumption as compared to other types of buildings. As such, an energy efficient hospital will bring about significant cost savings. Khoo Teck Puat Hospital, being Singapore’s first Green Hospital, is awarded Green Mark Platinum Award. Therefore, with such recognition, this research study aims to evaluate its lighting system management.

In summary, the whole study will examine the lighting management in three areas, namely artificial lighting, daylight provision and lighting control. This research study is conducted in two parts, in particular objective study and subjective study. Specifically, field measurements, interviews and site walkthrough are done to gain understanding for the evaluation of the existing lighting systems. The findings were compared with the Singapore Standards to determine if the acceptability of the existing lighting systems. Next, questionnaire surveys were conducted to determine the perceptions of the respondents on the current luminance level.

In conclusion, upon evaluation, several energy saving opportunities were found by reducing the artificial lighting provision. Additionally, feasible recommendations, such as the installation of dimmers, were proposed with aims to drive down the energy cost.
