Abstract

Fresh water is a scarce resource that is slowly renewable, so water management is very important to achieve the sustainability of architecture and urbanization through the medium and long term. Recently, environmental assessment systems have been given attention and development by many countries globally and regionally, and thus assessment systems have spread to help the architect achieve a sustainable environment and implementing green building practices. This can be implemented by adopting each system strategies such as energy, water, materials...etc. Since the scarcity of fresh water is a global issue, this paper aims to identify clear strategies of water efficiency and how to preserve it to obtain the best strategies that can be used to improve water efficiency inside buildings in Egypt. To attain this aim, The study follows a clear theoretical methodology in which the issue of water is recognized globally and its impact on architecture as well as water efficiency during the life cycle of the building. Then, a comparative analytical study was conducted for water efficiency between the local GPRS 2018 assessment system against the two global assessment systems LEED BD&CV1.4 and Green Star design & as built V1.3. The study concluded with an applied example by applying the strategies of water efficiency in GPRS2018, to clarify strengths and weaknesses points.
