Comparative Study of Water Efficiency in Green and Non – Green Buildings in Apparel Industry in Sri Lanka

At present, the amount of water demanded exceeds the water quantity that remains as a resource and it becomes scarcer each year. When it comes to water consumption in buildings, apparel buildings consume a considerable amount of water for both production processes and to fulfil the requirements of a large number of occupants. However, there are different perceptions towards water efficiency. As an example, one party is aimed at adhering the green building concept in order to retrieve water efficiency while another perception focus towards achieving water efficiency through various methods without giving consideration for adaptation of green status. Therefore, this study looks at how water efficiency is addressed and what benefits have being received for green buildings compared to nongreen buildings. Initially, a comprehensive literature review was carried out with the purpose of getting familiarized with research areas. Case study method was used to compare water efficiency status in green and non-green buildings in apparel industry. Two cases are selected from each building type for the data collection purpose. Semi structured interviews were carried out with respective industrial personnel and findings of case study was analyzed using the Nvivo. Research findings revealed that both green and non-green building are having similar purviews on the consideration towards the water efficiency and integrated with high quality water efficient practices to enhance the water efficient performances of the buildings. However, certain good practices could be observed in green buildings compared to non- green buildings. That is, individual commitment of the organisation together with third party commitment is making the building more towards water efficient. Finally, the study provides recommendations for good practices towards water efficient practices in the apparel industry.International Council for Research and Innovation in Building and Construction (CIB
