-مقياس مقترح لاستدامة المياه بالمباني السكنية أثناء مرحلة التشغيل في جمهورية مصر العربية

الملخص EN

Water is one of the most important environmental resources that occupies the world's attention at the present time, especially with the increase in population and urban areas and the limitations of these resources, and since the environmental dimension is considered one of the most important dimensions of sustainability; it is estimated that the world's built environment is the world's most water-consuming in operation, and that sustainable buildings can make a significant contribution to reducing water consumption.

in this regard, many agencies have made efforts to evaluate the performance of existing projects and buildings in the field of sustainability.

the existence of an accurate and objective local standard concerned with measuring the extent of water sustainability for a building, site or city is extremely important, as it is one of the most important tools and means that help achieve water sustainability in buildings, as it is a reference for designers and developers and a means to encourage them to design, construct and manage buildings that are efficient in water consumption, in a way that is more concentrated than the international and Arab standards, of which measuring water sustainability occupies a small part.

this is what this research paper will address, which will propose a measure of water sustainability in buildings in the Arab republic of Egypt during the operation phase, considering the impact of all local factors.

where this scale included a set of basic and advanced criteria for the efficiency of water use in the building, whether these criteria existed in one of the previous systems for assessing the sustainability of the building or were derived from them or proposed new criteria; each criterion consists of a group of categories formulated in the form of a question corresponding to points.

in the end, the extent to which water sustainability is achieved in the building is measured numerically, and the building is classified in terms of its water sustainability.

the research concluded the importance of adopting a qualitative measure of water sustainability, and the use of modern and innovative methods to control consumption water networks inside and outside the building.

I also recommend adopting the scale from one of the authorities concerned with sustainability, preserving, and developing water resources, and reviewing the legal frameworks regarding water consumption rates in buildings.
