Ahmed Khaled Mohamed II | P a g e Summary Water is becoming scarce not only in arid and drought prone areas, but also in regions where rainfall is relatively abundant. In water scarce regions, as is the case for the Middle East and North Africa regions, not only is the potential water availability in these regions low but that sustaining an increased demand requires innovative approaches to cope with water scarcity. Reasons for water scarcity are increasing world populations, global warming and water pollution. Currently towards 35% of human water use is unsustainable, humans currently use 40-50% of the globally available freshwater. Potable water consumption for nonresidential buildings is heavily dependent on use. Hotels have a proportionally higher requirement that can be accounted for, primarily, through washing and catering needs. The Red Sea region is one of the potential touristic zones facing water shortage in Egypt, although its touristic development strategies are primarily based on water availability. The sustainable use of water implies resource conservation, environmental friendliness, technological appropriateness, economic viability, and social acceptability of development issues. Water should be conserved during the whole project life cycle including design, construction and operation phases. Main approaches for water conservation include efficient use of potable water, reuse of wastewater and innovative use of non-potable water alternatives in all functional sectors of a resort. Many important decisions regarding a water-efficient building can be made during the operation phase of a resort. Such water-efficient practices should be selected based on design and construction requirements, adaptation with climatic conditions and achievement of water-saving, durability and suitable initial costs. The research aims to preparing a classification for all water efficient techniques that can be used in resorts along Red Sea coasts including potable water techniques and non-potable water applications. Another aim is to define all decisions that help architects to select the suitable water efficient techniques used in Red Sea resorts. The research discusses water efficient techniques used during operation phase. Then an analytical review is performed for the progress of water efficient scenarios in case studies. Finally, a classification is prepared for water efficient techniques used in resorts along Red Sea coasts. III | P a g e Abstract The increasing awareness of the accelerating rate of depletion of water resources is resulting in the high level of demand for water-efficient buildings. Currently towards 35% of human water use is unsustainable, drawing on diminishing groundwater and reducing the flows of major rivers: this percentage is likely to increase if climate change worsens especially "Global Warming", populations increase, groundwater becomes progressively depleted and supplies become polluted and unsanitary . The Red Sea region is one of the potential touristic zones facing water shortage in Egypt, although its touristic and economic development strategies are primarily based on water availability. The Red Sea region has no surface water sources, low rainfall seasons on highlands and high-saline coastal ground water aquifers. The sustainable use of water implies resource conservation, environmental friendliness, technological appropriateness, economic viability, and social acceptability of development issues. Innovation includes the adaptation of traditional know-how to the current day challenges, the adaptation of the externally available technologies to the prevailing physical and social conditions . The design, construction and operation of buildings have a tremendous impact on our environment and our natural resources. Green operation practices reduce resource use and pollution while increasing the value derived from each resource used. The building operation practices are large consumers of water. Many important decisions regarding a water-efficient building can be made during the operation phase. Some of these important decisions are using potable water efficient techniques, depending on waste water treatment methods and utilizing non-potable water applications. Water-efficient practices should be selected based on design and construction requirements, adaptation with climatic conditions and achievement of water-saving, durability and suitable initial costs . In this thesis, studying different water-efficient techniques which can be used in the Egyptian Red Sea region. First, categorizing all discused techniques based on type of water used (potable or non-potable water). Then, analysis of water consumption in all indoor functional sectors of the selected resort case studies along the Red Sea coast. Finally, concluding a rating categorization for the different water-efficient techniques which can be used during a resort operation. It also defines the related decisions made by architects to choose the suitable water-efficient
