Mm House

The house looks for the maximum energy efficiency adapting itself to the program, solar orientation, views and slope of the terrain. The project optimizes the program grouping it in four boxes –kitchen, living- dinning, main bedroom and guest bedrooms. Each box is placed carefully on the ground and rotate on its axis with precision to find the best views and orientation for their use. The house has been designed according to Passivhaus standards to achieve the maximum energy efficiency. Thanks to this design cooling is not necessary, which is typically an issue in the hot days of Mallorca's summer, and the heating demand is only 11kWh/m2a which is solved with a small perimeter underfloor heating circuit. The energy to heat the hot water is obtained from the solar thermal installation. The pitched roofs have a system for collecting rainwater for irrigation and consumption making the house completely autonomous in terms of water. The project has been made with a tight construction budget and a very low cost of energy maintenance. It is a home that promotes environmental and sustainability values, reporting savings and comfort without incurring additional economic effort. The house was finished last September and monitoring its performance has been key to value the results beyond the happiness and satisfaction of the clients. As of April the clients have not turn on the heat at all reporting an interior temperature (measured daily twice –day and night) for the winter between 21ºC to 24ºC, with exterior temperatures between 5º to 15º.
