How can we make a resort that produces energy instead of consuming it? What if 550 guests drink, swim, wash and clean without extracting water from the ground below? What could be a new level to establish a benchmark for “eco”resorts? How will the architecture perform under this challenging regime? FABRIC has attempted to address these issues through the design of the “Ecoresort Waterhill”. The concept of the resort is to be completely sustainable and based on closed cycles of water use, waste treatment and relies on its own energy supply. Furthermore this self sufficient system has a minimal impact on its surroundings in terms of architecture and material use. Based on a more closed water use cycles, the hotel uses the advantages of the Thai landscape. This steep landscape may be impractical but also can represent a tremendous reservoir to collect, store, filter, treat and reuse storm water and waste. A kind of sawa landscape, wonderland, where we can live. Under aquatic terraces we designed spacious villas. The roof of the hotel (200 rooms) is itself a large body of water, with water falling in the patios of restaurants and lobbies. The Ecoresort is entirely dependent on the excess monsoons. The excess of water is collected, stored and reused. The electricity is supplied by a biomass plant in a nearby ravine. Metal plates heat the water to boiling point, creating a thermodynamic able to efficiently respond to the needs of the complex.
