The project M15 involves the energy and spatial rehabilitation of a single-family house located in Madrid, in the protected urban area Colonia Unión Eléctrica Madrileña built in the 1940s.

The intervention respects the original character of the building and its surroundings and it focuses on two fundamental challenges: the improvement of the thermal insulation, together with a new climate control system that ensures the comfort of the house; and an interior spatial reorganization that promotes the interconnection between the spaces of the house, enhancing its relationship with the outdoor living areas.

The facade was originally divided into two bodies. The main body had a smooth plaster finish while the secondary body, which corresponds to the former garage, had a brick facade. To preserve the appearance of the original elements that define the protected facade, the first body is intervened by installing an external thermal insulation system, over the original façade, while in the brick body, the insulation is placed on the inside layer.

The improvement of the thermal insolation is combined with the installation of a ground source heat pump, a renewable energy source that feeds the underfloor heating and cooling system.
