Consideration of running costs : conventionalbuilding vs green buildings

‘Green Buildings’ aim at the efficient use of energy, water and material resources while reducing the impact of the buildings on human health and environment. Green Building reduces the Running Costs (RC) required for the operation and periodic maintenance of a building throughout its life cycles thereby providing significant financial benefits. In Sri Lanka, green buildings are being increasingly constructed, and the lack of understanding about the Life Cycle Costs (LCC) of buildings has resulted in several misconceptions and these contradict the research findings on RC of green buildings. Therefore, this study is aimed at identifying the savings from RC that can be obtained from green buildings, compared to conventional buildings. The research problem was approached through case studies, semi-structured interviews and a document survey. The findings were analysed using content analysis. It was revealed that the RC would vary depending on the function of the building, and that this cost is always less when compared with that of conventional buildings mainly due to the 78% saving on energy consumption cost. Furthermore, sustainable features in the building contribute to reducing energy cost during the running period. Consequently, it is essential to make the stakeholders aware of the RC of green buildings, to encourage them to move towards sustainable development
