Abstract:
Conserving energy and being sustainable is very important for any commercial building in the current
context. Since lighting systems consume a considerable amount of energy in a commercial building,
it is essential to implement energy efficient lighting systems. LED lighting is the most energy
efficient lighting technology that is commonly available today. LED lighting has been used in
commercial buildings in Sri Lanka for over ten years now. However, LED is still an evolving
technology and relatively new technology for Sri Lanka as well. Hence, there can be challenges faced
by the building sector professionals in using LED lighting. This study aims to identify the perception
of different stakeholders of commercial buildings, the challenges they have faced in implementing
LED lighting. Further it was necessary to the identify possible measures that can be taken to
overcome the prevailing issues were analyzed. A survey questionnaire was conducted among the
different stakeholders involved in commercial building projects during different phases of the
building life cycle. Further a desk study was conducted regarding the standards, regulations
prevailing in Sri Lanka and the initiatives taken by other countries to identify the possible strategies
that can be used to overcome the identified issues. It was found that stakeholders were enthusiastic is
implementing LED lighting but they had several concerns. The main challenge identified was the
lack of standards and relevant regulations in Sri Lanka with regards to LED lighting used for
commercial buildings. Further it was found that there are educational gaps among the professional
regarding LED lighting. In addition, it was found that the regulations in the building sector are not
sufficient to make energy efficient lighting mandatory. It was concluded that introducing
comprehensive quality standards for commercial LED lighting is essential and regulatory measures
should be taken to enforce energy efficient lighting in commercial buildings. These measures are
required to solve these issues and utilize the LED lighting in an optimum manner to reach the
sustainability goals of the country.
