Most Important Goals - Integrate seamlessly into the architectural environment - Construct a building complex without generating waste, or emissions of any kind. - Use only salvaged, reused or recycled. - Reduce the maximum energy consumption, and use only alternative energy. - Making the most of natural resources (sun, wind, rain) - Building a hotel is fully self-sufficient (water, power, waste recycling, food supply) 2. Architectural Solution Given the experience with the complex ACTIO, the objective of this new project is to further increase the effectiveness bioclimatic and self-reliance. Therefore, the architecture is similar. A large central space (greenhouse, garden-fresh) that acts as distributor to two lateral elongated bodies, in an east-west. Served spaces (with more energy needs) are located to the south and server spaces (with less energy requirements), to the north. The roof garden of the building is an extension of the top of the hill on which the building is semi-buried. Thus, the architectural integration with the environment is optimal. 3. Sustainable Analysis Same sustainable features that the Centre for Environmental Resources and Rural Tourism (ACTI). 4. Bioclimatic characteristics 1.1. Heat Generation Systems The building is heated by itself, in two ways: 1. Avoiding cool: Due to its high thermal insulation, and having most of the glass surface to the south. 2. Because of his careful and special bioclimatic design, and perfect NS, the building is heated by greenhouse gases, direct sunlight and radiant floor heating based on solar-heated water. 1.2. Fresh Generation Systems The building is cooled, by itself, in three ways: 1. Avoiding hot, providing the bulk of the glass surface just south and west, providing sun protection for the direct and indirect solar radiation, and providing adequate insulation. 2. Cooling by a cooling system architectural air through underground tunnels. On the other hand, due to high thermal inertia of the building, the accumulated fresh overnight stays for nearly all the next day. The fact that the building is partially buried possible that tends to keep cool, and even temperature, throughout the year. 3. Evacuating the hot air outside the building, through metal solar chimneys, and the large central space. The special architectural form of the power center cover natural convection and provides an effective "chimney effect" to extract the hot air inside the building. 3. Storage systems (heat or cool) The heat generated during the day in winter (greenhouse effect, solar radiation and the system of solar radiant floor heating) accumulates in the floors and interior load-bearing walls of high thermal inertia. Thus, the building remains warm throughout the night, with little energy. Generated during the cool summer night (for natural ventilation and outside due to lower temperature) is accumulated in the floors and interior load-bearing walls of high thermal inertia. Thus, the building remains fresh throughout the day without any energy consumption. The roof garden (about 25 cm. Of land) of high thermal inertia, in addition to proper isolation, maintains a stable temperature inside the building, which is kept warm at night and cool during the day. 4. Transfer systems (heat or cool). The heat generated by the greenhouse effect, natural radiation and soil heating is distributed in the form of hot air throughout the building by the central corridors of distribution. Similarly, the heat accumulated in the load-bearing walls is transmitted to the rooms after radiation. The cool air generated in the underground galleries are distributed in buildings, through a set of grids spread over the floors. 5. Natural ventilation The ventilation of the building is in a continuous and natural, through the very walls surround, allowing adequate ventilation without energy loss. This type of ventilation is possible as all materials are breathable (ceramic, lime-cement mortar, paint silicates), although the whole performance has a completely waterproof compared to rainfall. 5. Outstanding innovations - Strategies for reducing construction costs. - Building system that allows the abundant use of recovered materials and recycled materials. - Integration architecture optimized, high added value, thermal solar collectors, photovoltaic solar collectors and wind generators.
