Hsinta Ecological Power Plant International Competition - A Sublimation Mechanism of Carbon Cycle and Ecological Compensation
The site of Hsinta was once the income (saltpan), wildlife habitat, and historical location and is now an energy source for people living far from this area. The future power plant here should take the responsibility of maintaining the law of conservation of energy, ecological integrity, and environmental justice. Therefore, we not only propose an ecological power plant but also a mechanism that combines energy flow, natural cycles, and human movement into inseparable circles.
From the perspective of migrating birds, the compact, ecofriendly power plant is located on the least environmentally sensitive corner and is hidden by natural skin. Three centralized air chimneys provide a green structure to serve both energy and ecological purposes. It forms a shape that follows the seasonal air current, which can lead various migrating birds down into diverse wetland habitats.
From the roof level, it is a demonstration of carbon sink. Solar panels on the top are repositioned from the current photovoltaic system and free up an area of 9.45 ha for environmental education. Below the solar panels is a double skin green façade that connects to the centralized chimneys. The inner layer of the skin protects the power plant, and the outer layer can provide space for plants, and maximize the carbon sequestration. Air flow between layers can reduce the building temperature, provide natural ventilation for habitats, and change the local micro-climate to improve air quality.
From the ground level, diverse wetlands, open water, ponds, marshes, mangroves, etc. are restored based on the natural wildlife habitats. From our survey covering many years, the site can be highly diverse. Human consumption takes space away from wildlife, and it should be compensated. The sociocultural life for local communities is reconnected to the site. Educational and community programs are included but are spatially and visually separated from the topography. There shouldn’t be energy waste from the system. Heat left over from the turbine generator will warm the local fish ponds or be reused by the local community. The topographical approach forms a harmonious earth-scape that blends natural activities inside the site. The next-generation power plant should play the role of “recrystallizing” the original composition, which includes habitat, nature, and social welfare.
