Owner approach of sustainability
The developer was advised by the architects team in order to reach these three main goals: respect for the original building, creation of sophisticated and unique spaces, and sustainability of the whole intervention and life cycle.
Architectural description
Everyone who has dealed with the renovation of a listed building like this, has confronted a lot of difficulties in order to achieve the requirements and needs of a XXIth century familiy. The're hard legal restrictions to prevent damages to the cultural values of this kind of buildings. Nevertheless the developer and the architects' team found this issues as an extra motivation to design a highly energy efficient building with great cuts of energy consumption values. For example at the façades the intervention had to be based on a long search of the best insulation options for the interior layer, on the construction and design of new doors and windows based on the original design and with the original materials but with great insulation values; and on the inclusion of high performance glass types. The accessibility of all the ground floor spaces was also a goal to achieve so that everyone can enjoy the great tour through the green spaces that ends at the huge vertical garden of the rear court. This "presence of the green" makes the building a living organism.

Product
-
There is a double flow mechanical ventilation system that, after passing through a heat exchanger, throws out the interior air. It also has the free-cooling tool in order to reduce air conditioning use by chilling the house during the night.

-
There are 8 heliostats installed at the roof of the building in order to introduce solar light in the interior courts, specially in the little ones. These heliostats work with a static mirror each, so that the first follows the sun and the second is orien

There are several systems introduced in the building in order to provide acoustic comfort to the stakeholders:
- A new floor layer for impact noise absorption.
- A new rockwool insulation layer over the continuous dropped ceilings
- And an acoustic and thermal insulating glazing, for doors and windows, with laminated interior and exterior layers (4+4/ 16 / 5+5 SILENCE)



Urban environment
The building is placed in an urban consolidated prime area of Madrid: the Salamanca District. It´s perfectly connected with the public transport network (three underground lines and several bus ones), surrounded by lots of stores and every kind of service, and real close to Madrid's green lung: the "El Retiro" park.

Reasons for participating in the competition(s)
El proyecto de rehabilitación integral de Príncipe de Vergara 11 está basado en conjugar tres aspectos fundamentales:- el respeto al patrimonio y a la calidad de la obra original de 1913 y obra de Eugenio Fernández Quintanilla- la creación de unos espacios únicos y sofisticados con todas las comodidades que debe ofrecer una vivienda del siglo XXI y- el respeto por las personas, el medio ambiente y la eficiencia energética.
Prueba de ello son la recuperación de materiales originales, la disposición de las estancias amplias y abiertas, los grandes aislamientos en carpintería, fachadas, cubiertas y soleras, las extraordinarias zonas ajardinadas y el jardín vertical y la comunicación accesible de todos los espacios en planta baja.
