A creba Island or Illa da Creba, is a Spanish island in the province of A Coruña. It is located on the estuary of Muros and Noia, 240 meters from the shore of the parish of Esteiro. With an area of 7.5 hectares, it is topped by a large house. It is a building constructed in the early 80s, with a floor space of 516 m² spread over 5 full bedrooms, kitchen, living room and technical areas an an outdoor pool of 35 m². The aim is to replace the existing energy source with a total dependence on oil, comprised of a generator and diesel boiler by other existing sources of renewable energy on the island, always searching, when possible, the energy self-sufficiency, which is achieved in most part of the summer period (May -September).

Owner approach of sustainability
The main objective of the promoter is self generation of the energy necessary for the proper functioning of the housing, showing the utmost respect for the environment and the natural environment of the area in which the house is located. Until now, all the services enjoyed by the house were totally dependent on fossil fuels, particularly diesel, and given the location in which it is located, supply had to be transported by boat. All these constraints meant that housing facilities proved to be totally ineffective, causing significant economic cost and considerable CO2 emissions into the atmosphere.
Architectural description
The house dates from the late 80s and is in good condition, so the only architectural reform is done in the kitchen, in order to adapt its conditions to a continued use of housing. It is a large house that has traditional bioclimatic strategies such as the high thermal inertia of its stone walls and the existence of local wood fireplaces.
