Owner approach of sustainability
The promoter of the building is the Barcelona City Council. Bimsa is the municipal company in charge of the management and supervision of the projects. The terms of the tender and the specifications laid down the need to introduce sustainable and energy efficiency parameters, aiming to achieve almost null consumption buildings nZEB.
Architectural description
Vil·la Urània is a small residence of the late nineteenth century that was home to the renowned astronomer Josep Comas i Solà, in the district of Sarrià-Sant Gervasi in Barcelona. The re-densification of the neighborhood left the building and the small surrounding garden encased between two large medianeras. The new complex of equipment assumes the challenge of giving a new life to the existing building and gardens by incorporating it into a new building of low environmental impact and reduced energy consumption. The extension is conceived as a tall and narrow building, oriented to South-east with a large gallery, a semi-detached greenhouse, which passively air-conditions the meeting areas and informal activities as well as the circulation of the building. This intermediate space functions as a winter greenhouse and as a shade in summer, and acts as a thermal mattress by separating the heated areas from the outside, reducing the energy demand of the building. The facade adapts automatically to outdoor conditions. Indoor temperature sensors act on the glass facade, opening it completely when necessary. Outside probes measure solar radiation by acting on the folding shutters in summer. The inner plantation formed by different species provides a pleasant sensation of freshness in summer, while in winter reduces its volume to allow to capture the solar radiation. The building envelope has been designed to achieve low thermal transmittance, minimize thermal bridges and a high level of tightness.

Product
-
Swegon heat recuperator

HVAC, électricité / ventilation, cooling
High efficiency heat recovery units
Silent and compact. Acceptance by all parties has been very good
-
Halton Rex chilled beams

HVAC, électricité / heating, hot water
Ceiling induction elements. Active chilled beams that provide heating and cooling by incorporating treated renewal air from the heat registers
Easy maintenance, no fans or filters. They are "exposed", facilitating access to controls and drives
Urban environment
The building is located in a very consolidated area of the city center of Barcelona with different options of public transport. Vil·la Urània was surrounded by large dividing walls of the adjoining buildings. The high and narrow building was designed to avoid the demolition of the preexisting vil·la and with its little occupation to liberate an interior garden.

Los acristalamientos se han seleccionado dependiendo de su ubicación concreta:
Acristalamientos entre espacio Interior y el Exterior: Ug:1,3 W/m2K TL:70% g:0,41
Acristalamientos entre espacio Interior y el Intermedio: Ug:1,5 W/m2K TL:78% g:0,65
Acristalamientos entre espacio Intermedio y el Exterior: Ug:5,4 W/m2K TL:80% g:0,82
Carpintería de madera Um:2W/m2K
Se han escogido sistemas activos de alta eficiencia, así el edificio dispone de una bomba de calor geotérmica de 200kW con 11 pozos de 100m de profundidad (100kW) que se combina con un evaporador remoto de 160kW para los momentos punta y cuando la temperatura exterior es más favorable. Las salas disponen de inductores (bigas frías)y un sistema de aire primario proporcionado por recuperadores de calor de alta eficiencia controlados por sensores de presencia y de CO2 para realizar la renovación de aire solo cuando es preciso. La iluminación es LED y el edificio dispone de producción fotovoltaica con 19kWpic instalados.
El edificio destaca también por la utilización intensiva de materiales de bajo impacto ambiental, rápidamente renovables y de origen reciclado, entre ellos; estructuras auxiliares y carpinterías de madera, muros cortina mixtos madera-aluminio o aislamiento de cáñamo. Un depósito enterrado de 20.000L permite recoger agua de lluvia y usarla en un circuito cerrado para el riego de la plantación del edificio.
El edificio dispone de certificación energética A y la certificación leed oro en fase de proyecto, se está tramitando la certificación leed platino para el edificio terminado.
