To address the water crisis, this is a research centre on water which contains a system of water mechanism, that functions as a model device for efficient harvest, collection, storage, purification and practice of water. The structure follows the behavior of water, and controls the transformation and journey of water from the scale of the landscape to the scale of the body using gravity, atmospheric pressure, wind, and solar radiation. It provides water to 100 inhabitants. The scale to which it relates is climate and water supply source. It is not attached to local coordinates, but rather to global coordinates: weather, water, atmospheric pressure, technology, interaction, and flexibility. The structure houses programs for living spaces, recreation spaces, energy and water harvesters, and research facilities that focus on collection techniques and transportation devices for water, hydroponic farming, and urban data analysis. Water systems are incorporated in all programs to create different micro-climatic environments.
The programs and spaces are regulated and conditioned by water, attributing to the quality of life and well-being. This entails optimal levels of temperature, humidity, sunlight, ventilation and communal interactions. Spaces are categorized and organized for optimal functioning, on the basis of quantity and purification quantity of water consumption by every space in each program. Water is circulated and exchanged within these spaces. Being the main material, water accounts for 70% of this building.
It is a breathable building with no set limits; it plans connections, processes, influences. In this sense, the inhabitants live in an open structure surrounded by water, which acts as insulation during the purification process. The building is an environment in dynamic energy relations, which blurs the boundaries where it is not easy to know if it is inside or outside. One does not enter this building; one arrives, it is like reaching a landscape. The innovation of the structure is to create environments governed by heat, pressure, and gravity. The system starts with capturing solar radiation by parabolic magnifier to boil water, which is harnessed and collected from nature. Vapor transformed from boiling water inflates a balloon; which causes negative pressure when it deflates. This pressure change is connected to the pipeline system, which draws the cold water against gravity and circulates it in the vertical structure, reducing the environmental temperature, creating a cooler micro-climate where the program sees fit. Likewise, the hot water transformed by solar radiation is connected to the pipeline system to create a warmer micro-climate. Thus, a cyclic and repetitive movement of water is achieved, a series of different microclimates are created, and the system can operate continuously. The objective is to modulate the environment by reducing or increasing its temperature by using transmission of energy between hot and cold focus, using the principle of thermodynamics. The circulation of hot and cold water transforms the environments by providing heat or coolness when necessary. In parallel, these modulations also alter its humidity and content of water from a wet to dry focus. Containers, filters, tubes, valves, parabolic reflectors, and hydraulic wheels are the elements that control these processes.
