Zero Carbon Resorts
Puerto Princesa, Philippines
The aim of the planning and development team was to construct a residential and tourism building suitable for everyday use, whose consumption of resources during construction and use is as low as possible and at the same time can be realized with regionally available resources and technologies. Thus, in terms of materiality, it adapts to the original development on site, while offering high modern living comfort.
The building is a single-story house that stands on point foundations. The foundations themselves are made of concrete with steel anchors. The building on top was constructed using only ecological materials such as bamboo, palm leaves, wood and clay.
Building materials available on site ensure great resource efficiency, and rainwater is collected, purified and used for shower and toilet. A small biological sewage treatment plant, a small photovoltaic system and extremely energy-efficient fans ( 5-18 W) characterize the independence of the object as well as its technical equipment (for example: solar stove, solar-powered lighting, hot water via solar system). GrAT is currently developing projects for further demonstration buildings in Thailand and Nepal.
Completed in 2015. Area: 114,42 m²
