| description | Global overall energy consumption is rising. Along with it, a relative contribution is
lighting energy. While existing light sources are reaching their limit of performance, LED-based light
sources are however offering the potential to meet energy saving targets with their improving
performance. In most buildings, the dominant light source is the fluorescent lamp. Although it is
energy efficient, the total energy consumed is still significant, especially more so for public
institutional buildings in Malaysia. This research studied the application of linear LED replacement
tubes as the alternative retrofitting energy efficient solution to the existing fluorescent tubes in the
International Islamic University Malaysia Main Library. The study assessed the potential to reduce
energy consumption and consequently, the electricity bill but without reducing the performance. The
methodology adopted the data collection technique through physical walk-through audit and an
observational survey of the existing lighting situation. Using the Lighting Power Density (LPD)
calculation methods from ASHRAE and IESNA, a recommended light level and cost analysis were
undertaken. With the LED retrofit, the recommended lighting levels were established, and an annual
savings of 33% was predicted in one academic building, with a return on investment period of less
than two years. |
