    Green building concept to facilitating high quality indoor environment for building occupants in Sri Lanka
    (2012-06) Mallawaarachchi, BH; De Silva, ML; Rameezdeen, R; Chandrathilaka, SR; Mallawaarachchi, B.H., De Silva, M.L., Rameezdeen, R., & Chandrathilaka, S.R. (2012).

    Well-being is an important aspect determining the quality of life of an occupant. Hence, it is essential to have a good indoor environmental quality, as it affects the productivity and health of such occupants. Further, indoor air quality, acoustic, day-lighting and thermal comfort contribute to better indoor environment quality, and have a positive effect on an occupant's productivity and performance. Accordingly, many studies believed that the green building design will become more common practice once the human benefits are identified, primarily the productivity gains believed to be associated with the provision of high quality indoor environments. Hence, buildings are increasingly designed or required to be ‘green’ in recent years, giving the quality of the indoor environment new importance. Therefore, several green building assessment tools have been applied worldwide namely, Leadership in Energy and Environmental Design (LEED), Building Research Establishment Environmental Assessment Method (BREEAM), Comprehensive Assessment System for Building Environmental Efficiency (CASBEE) and Green Star etc in facilitating high quality indoor environment. Indoor Environmental Quality (IEQ) has considered as a major criteria in such tools. Thus, various IEQ factors relate to temperature and humidity, acoustic, ventilation, indoor air quality, day lighting and lighting quality, thermal comfort and access to views have been considered in these techniques. Similarly in Sri Lanka, GREENSL® Rating System is applied for buildings in local context so as to obtain green certification. Even though, it emerges IEQ as an important aspect, it is considerably less compared to other domains. Thus, four green assessment tools were suggested which can be applied for buildings in Sri Lankan context through the review of key research papers. Accordingly, such green building tools can be considered for Sri Lankan buildings as a new concept/tool or even the existing system can be further enhanced so as to provide a better quality indoor environment for building occupants.

    Risks and risk assessment methods in industrial maintenance in Sri Lanka
    (2012-06) Wijeratne, WMPU; Parera, BAKS; De Silva, ML; Wijeratne, W.M.P.U., Parera, B.A.K.S. & De Silva, M.L. (2012). Risks and risk assessment methods in industrial maintenance in Sri Lanka.

    Studies on industrial maintenance operations worldwide have identified several maintenance specific risks such as working at heights, the pressure of time, etc. However, there is a dearth of published research on risks and risk assessment methods in industrial maintenance in the case of Sri Lanka. This study therefore aims at identifying the risks and risk assessment methods in industrial maintenance in Sri Lanka. The main objectives of the study were to identify the occupational risks and safety issues in maintenance work and the risk assessment methods in place in the Sri Lankan context. This was undertaken through a study of three manufacturing organisations which are involved in producing fastmoving consumer products. According to the findings, the risks which affect maintenance work can be categorised as organisational risks, unsafe acts and local workplace risks. The findings indicate that the most typical risks associated with maintenance are cuts, slips and falls, with severe or fatal injuries the result of worker disregard for standard operating procedures and/or failure to use the protective equipment provided. It was also found that check lists, brainstorming, and decomposition techniques are the preferred methods in maintenance for risk identification while a risk-rating matrix is used for risk analysis. The findings of the study highlight the safety risks entailed in the maintenance operations of manufacturing organisations and the risk assessment tools used in identifying the risks. The findings of the research will be useful for those in industrial maintenance operations for the purpose of managing risks effectively by designing work environments that are risk-fee and for educating workers on the importance of paying due attention to risks and the need to follow instructions that are in place on safety procedures in the workplace.
