Arroyo Fresno Passivhaus is the first nZEB collective residential building in Spain to obtain Passivhaus Plus certification. It is a project by Daniel Diedrich and Talia Dombriz of DMDV Arquitectos.

Located in the PAU of Arroyo Fresno in Madrid, it is configured with a simple prismatic volume containing 14 dwellings distributed over four floors above ground and resting on a porticoed ground floor and another floor below ground level. The floor plan is limited by the urban planning regulations establishing the limits of three of the visible facades. The remaining, smaller façade is adjacent to the neighboring building. Formally the building is conceived as a prism with great compactness, where the facade has the same finish in continuity only altered by the use of color, forming a zigzag band that runs between the order of window openings on each floor, seeking a formally clear singularity without altering the simplicity of the concept. 

The building is passive in all its living areas, between the first and fourth floors, while the first floor opens to the outside with a porch access to the two portals. On this floor the space belonging to the thermal envelope is the one that closes a community room for coworking of the users of the apartments.

Each apartment has air conditioning by individual aerothermal pump and emitters through underfloor heating / cooling, and an individual mechanical ventilation system with double flow with heat recovery.

In addition, the building has a photovoltaic installation for electricity generation.

Domestic hot water is generated by a centralized system with an air/water aerothermal pump, a distribution circuit and accumulation and production tanks that become energy storage when there is a surplus of electricity production in the self-consumption valleys.

The elevators, with low energy consumption, are equipped with an electric power generation system during braking.

The proposed building "Arroyo Fresno Passivhaus Plus" is a Passivhaus Plus certified nZEB building with a very high level of construction rigor, and a refined design for the requirements of high-rise housing use, based on the exhaustive study of bioclimatic implementation in the plot by the constraints of the applicable urban regulations.

The building envelope has been optimized with the maximum criteria of the Passivhaus Institute (facades, floors and roofs, carpentry and glazing as well as solar protection) which reduces the building's heating demand to 14.40 kWh/(m2y) and cooling demand to 8.60 kWh/(m2y). The air infiltration test has been passed by Blower Door Test per housing unit and ground floor coworking space with a result of 0.58 1/h (n50), guaranteeing the airtightness of the volumes.

In addition, the air conditioning systems have been optimized with Daikin Alterma 3 aerothermal underfloor heating and cooling per dwelling unit (Heating capacity=4.6 kW. COOP=3.8) and a centralized domestic hot water system has been developed in the building consisting of a Mitsubishi Heavy Industries Q-Ton pump (heating capacity=30 kW. COOP=4.3) with two 3,000 liter DHW storage tanks. Furthermore, the ventilation system has been realized individually per living unit and coworking area, using Zehnder mechanical ventilation with heat recovery with an efficiency of 82%.

The renewable energy generation system is based on a rooftop photovoltaic system consisting of 61 Canadian Solar panels and Fronius DC/AC inverters with a total output of 32.97 kW/year.

The rigorous study of the optimization of the envelope and systems means that the high-rise housing and the first floor coworking space meet the optimum conditions to guarantee the success of a passive self-consumption building, with maximum indoor air quality and comfort in its spaces.

Owner approach of sustainability

Promote buildings under the Passivhaus standard with the aim of obtaining and marketing buildings with a really low energy demand and reducing CO2 emissions.

Architectural description

With a useful area of 2,475.54 m2 (including garage in the basement) on a plot of 1,287.85 m2. The plant is limited by urban regulations establishing the limits of three of the facades. The remaining facade, the minor one, is a dividing line with the neighboring building.

Formally, the building is conceived as a prism with great compactness , where the facade presents the same finish in continuity only altered by the use of color, forming a zig-zag band that runs between the order of window openings on each floor, looking for a formally clear singularity without altering the simplicity of the concept.

The building is passive in all its habitable areas , containing houses on the first and fourth floors, while the ground floor opens to the outside with a porch covered by a large cantilevered access to the two portals. The space of the community room or coworking room for the users of the homes is located on this floor, to facilitate work at home or telework.

The free space outside the plot is landscaped and urban gardens associated with each of the houses are projected.

If you had to do it again?

The installation of the sealing and hermetic systems of each house had to be repeated to give values lower than 0.6 ren / h. In similar cases, double sealing must be performed at each meeting or joint.

Urban environment

Urban Action Plan for Arroyo Fresno in Madrid capital. It is characterized by the fact that all the plots are of new execution and of homogeneous characteristics with majority residential use.

The plot is located within a block of the APE.08.16 “Arroyo del Fresno” of the current General Plan of Urban Planning of Madrid, a newly created urban development in the North of Madrid that belongs to the Mirasierra neighborhood. It is bordered to the north by the M40 ring road, to the east by the Monte Carmelo neighborhood, to the south by the Peñagrande neighborhood and to the west by the Portillera del Fresno golf course that separates it from Monte del Pardo.

As it is a newly developed area, the existing building is for the most part in execution, although it will be homogeneous by sharing development regulations. In general, the urban environment is of quality, in a quiet residential area with little traffic and a high socioeconomic level, with good urban services and easy road communication.

The Passivhaus PLUS certified building has a thermal envelope in accordance with the Passivhaus Institute criteria (facades, floors and roofs, carpentry and glazing as well as solar protection) which reduces the building's heating demand to 14.40 kWh/(m2y) and cooling demand to 8.60 kWh/(m2y).

Air infiltration test has been passed by Blower Door Test per dwelling unit and ground floor coworking space with a result of 0.58 1/h (n50), guaranteeing the airtightness of the volumes. Each dwelling has a double-flow mechanical ventilation system with Zehnder heat recovery.

As renewable energy systems, it uses individual aerothermal pumps per dwelling for DAIKIN Altherma 3 air conditioning and centralized for DHW Mitusbishi HI Q-ton, in addition to a photovoltaic installation of 61 Canadian Solar solar panels and Fronius inverters of 32.97 kW/a
