This thesis investigates the application of rainwater harvesting in architecture by surveying a selection of historic and contemporary examples in building or neighborhood scale. Since Minoan times (ca. 3200–1100 BC), the method of rainwater harvesting has been applied for water supply in settlements and buildings as primary or alternative freshwater resource. It also offers a convenient solution to alleviate water demand from municipal network and to support transitional shelters, and to offer self-sufficiency to off-grid buildings. From the large amount of water existing on the planet, only a limited portion is fresh and only a small fraction of that is easily accessible for the multiple types of water use -agricultural, industrial, domestic, etc. Considering the current water stress around the world and the strong probability of future water scarcity, rainwater harvesting - the traditional water supply method of rural, arid, semi-arid or sparsely populated areas - comes forward as an alternative solution to meet global water demand. This study surveys at first various techniques of freshwater harvesting from different sources of water - underground, surface, and atmosphere. As one of such techniques, rainwater harvesting is studied further, focusing on the reasons that make it important as a water supply, its place in the world today and in the past, its practical phases, and its implementation in architectural applications, in order to comprehend the various aspects of the subject. The study continues on the relation between rainwater harvesting and architectural form as the main concern of this thesis, surveying various design possibilities on ways to emphasize rainwater harvesting through the architectural form. The work sets three objectives in relation to rainwater harvesting : • to "combine modern water systems and old rainwater harvesting methods or to modernize the existing rainwater knowledge to benefit human settlements facing water scarcity" (Akpınar Ferrand and Cecunjanin, 2014), • to emphasize its prominence among the architectural attributes, and • to increase the water-awareness through built environment. For that purpose, a number of possible changes in the visibility of rainwater harvesting, and also how it can become a form-determining factor for architecture were discussed. The main phases of the system (collection, conveyance, storage, treatment and distribution) have been reviewed, and suggestions regarding how the components of these phases can become architectural elements have been developed.
