    An Evaluation on the adoption of leed green building rating system in the Sri Lankan context
    Jayasinghe, V; De Silva, ML
    Building design and construction activities worldwide have caused immense environmental issues. Thus. the concept of green buildings emerged focusing on increasing the efficiency of resource use -energy, water and materials while reducing building impacts on human health and the environment. Many green building rating systems have been developed by various countries while Leadership in Energy and Environmental Design (LEED) of the United States is the most widely accepted throughout the world Yet. a benchmark for green buildings in Sri Lanka has not been established Therefore, this research paper presents the findings of a research which aimed at evaluating the LEED for New Construction (LEED-NC) green building rating systemfor its adoption in the Sri Lankan context. A quantitative research approach was followed to achieve the objectives. The preliminary survey identified the factors affecting the adoption of green building requirements locally while the detailed questionnaire survey evaluated the professionals' perception regarding the LEED-NC credit requirements in terms of three factors identified in the preliminary survey, namely, environmental compatibility, technical feasibility and initial incremental cost. Thefindings revealed that almost all of the LEED-NC credit points are environmentally compatible and technically feasible in Sri Lanka. Further, most of the credits were found to be achievable without incurring significant initial incremental costs. In addition, a strong link was observed between credit adoption patterns of LEEDNC credits in the existing LEED accredited green buildings and the above three parameters portraying that these parameters influence the adoption of LEED-NC credit requirements in Sri Lanka.

    Quality assurance of low cost building construction
    Kanagaratnam, H; De Silva, ML; Hadiwattege, C
    Construction industry is complex in nature, therefore quality assurance is paramount important and it is absolutely interconnected with cost. Quality is essentially a state of mind; it varies from individual to individual. In the concept of low cost building onstruction, the achievement of an acceptable standard in buildings is a combination of quality of design and construction and quality of maintenance. With this perspective the research problem addressed here is related to the gap in knowledge to be filled in the area of quality assurance in low cost building construction in Sri Lanka which has not much of attention have been paid. This study therefore has been conducted to answer the issues of quality assurance in the low cost constructions which is having a critical comparative importance. The research methodology adoptedfor this study is both quantitative and qualitative, within which a survey and few case studies were used to investigate the research question. The primary data collection techniques used in the case studies was questionnaires, interviews and observations. Content analysis and statistical tools were used to analyze primary data. The study has identified that even though ICTAD is required to maintain the ISO 9000 quality standards for the construction works, majority of the low cost constructions are not adhered to the standards in an effective manner and end up with quite a lot of quality issues as well. Further, researchers suggest some good practices to be maintained for better quality assurance in low cost buildings which are practically achievable but unfortunately not in the current construction practice.
