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.

Energy consumption

• Primary energy need : 32,80 kWhpe/m².year
• Primary energy need for standard building : 81,80 kWhpe/m².year

Calculation method : RD: 47/2007

• Final Energy : 21,00 kWhfe/m².year
• Initial consumption : 139,20 kWhpe/m².year

Envelope performance

• Envelope U-Value : 0,29 W.m^-2.K^-1
More information :

Design, shapes, colours, materials, carpentry, quality and any other characteristict of the building façades (both interior and exterior) are law protected. Because of this all the envelope insulation efforts have been concentrated in the interior layers of the envelope:
- There's a new multilayered reflective material. It works with the dry wall profiles in order to create a very effective closed air chamber
- There are new timber carpentries with the original design in order to make them able to carry insulated glazing (with air or argon chamber depending on the cases)
- The roof has been designed with a XPS 12cm. thick layer
- And the ground floor has been constructed over a cavity system basis that creates a closed air chamber. In addition there is also a MDF board plus a rockwool layer.
As a result of this constructive systems we have reached the following remarkable data for this latitude:
U average Ground Floor 0.49
U average Façades 0.29
U average Roof 0.19
U average Windows 1.30

Indoor Air quality

There´s a whole plumbing system that recovers the vertical garden watering excess. In addition there is a 2500 l greywater recovery tank for watering purposes.

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.

Product category :

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)

Construction and exploitation costs

• Renewable energy systems cost : 8,89 €
• Total cost of the building : 8 133 653 €

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.
