Energy-intensive building

The comprehensive energy rehabilitation of the residential building on Calle Montalbán 11 in Madrid is a unique project in our country destined to become part of the artistic heritage of the capital thanks to five key points:

  • the historical value of the property, restored and preserved in the intervention
  • the unbeatable location next to the Retiro and the cultural epicenter of the city
  • its careful interior design in homes and common spaces
  • its respect for the environment and sustainability accredited in a BREEAM “Very Good” certificate and an A energy rating
  • and, of course, the intervention of the artist Carlos Cruz-Diez with a Chromatic Setting in three stages.

Owner approach of sustainability

The promoter, Italinmubles, has always shown an interest in sustainability, from the beginning of the project to the end of the work. Low consumption, the search for well-served locations in terms of services, active and passive measures, respectful materials, etc ... have always been sought and validated by the developer and the architecture studio to achieve an optimal and sustainable result. .

Architectural description

The building, built in the Barrio de Los Jerónimos in 1916, was expanded by three floors in the postwar period. Thus, the ensemble coincides with structures made of wood, brick, steel and cast iron, and reinforced concrete. Now we have completed its second major reform, respecting the main façade and the central patio, changing the location of the main staircase (recovering and restoring its most valuable pieces), and creating, through a complete removal, two new basements that include an automatized parking for 32 spaces (five electric). Nine homes, storage rooms, indoor pool, gym, multipurpose room, sauna, hammam, and common patios vegetated with native species complete the uses of its more than 4,600m2 built (3,300m2 SR and 1,300m2 BR). Everything is worked with a careful interior design with materials of the highest quality and proximity.

The sustainability of the intervention is endorsed by the BREEAM Very Good certification, one of the first qualifications of its kind in residential rehabilitation in Spain. Product EPDs, wood provenance certificates, VOC emission certifications, lighting efficiency and many other aspects related to sustainability have been carefully required and reviewed by designers and certifiers. The efficient use of water, with the recycling of gray water for the irrigation of common areas, and the use of natural lighting, with fixed mirrors in small patios that manage to make sunlight reach the lowest plants, are completed with more 70m2 of green areas for common use, a luxury in the center of Madrid. Regarding energy efficiency, a large number of passive measures have been used (large insulation, energy-saving glazing, low transmittance carpentry, ...) and among the active measures implemented, the use of geothermal combined with low-temperature terminals stands out. and ventilation systems with heat recovery.

The building is completed with something unique in our country: a work of art specifically designed by Carlos Cruz-Diez in three stages. The first is the mural integrated into the Induction Chromatique à Double Fréquence hall, the second is a vibrant Chromointerférence that can be seen from the elevator car; and the last stage is the Transchromie that are located inside the houses.

Energy consumption

  • 17,00 kWhpe/m2.year
  • 61,00 kWhpe/m2.year

  • 8,00 kWhfe/m2.year

    • ESTIMATED:
    Heating, DHW, cooling 32%
    Ventilation 8%
    Illumination 5%
    Robotized Garage 21%
    Common services 18%
    Household appliances and other 16%

    All energy consumption for air conditioning and DHW is electric (geothermal pump plus aerothermal pump)

  • 262,00 kWhpe/m2.year

  • 5,45 %

    • It is a mixed geothermal system with probes in the field + aerothermal both for the generation of heating / cooling and for DHW.

    There is no production of renewable energy but a geothermal installation that saves electricity consumption. The production has been calculated based on the electrical savings: over the total of the building, 43% of the production for cooling, heating, and DHW is produced with the geothermal machine.

    Solar mirrors that guarantee natural lighting in patios, saving electricity consumption for artificial lighting.

Comfort

    Luminaires that have LED lamps have been selected to reduce the risk of health problems related to the flickering of fluorescent lighting. User controls have been provided to all dwellings that allow independent adjustment of the temperature of the heating and cooling systems within the building. The improvement of the quality of life of the occupants has been promoted by providing an outdoor space for their use and which provides privacy.
