Description

PHI Low Energy Building certification for single family house with a treated floor area of 125.4 m², located in Castellcir, Barcelona. Designed by Lluís Jubert of Taller d´Arquitectura, promoted by Núria Grau and Jaume Ribas and built by Albert Fargas of Farhaus.  

The construction system is lightweight timber frame, using low-emission, bio-based materials with low environmental impact to reduce the building’s carbon footprint and provide a healthy indoor environment. The high level of insulation, minimised thermal bridges and triple low-e glazing with Farhaus timber frames, reduce heating energy demand in the winter. In the summer, external blinds reduce solar gains and overheating. Mechanical ventilation with heat recovery is provided by a Zehnder ComfoAir 180 HRV.

As part of the Passivhaus audit, Praxis revised the calculations and design documentation presented by the Passivhaus Consultant, which include architectural and M&E drawings and reports, the PHPP calculation, the Blower Door test report, ventilation commissioning documentation and photographs of the construction process and the completed building.

Praxis has carried out the Passivhaus Classic certification of this single-family home in Lekunberri, Navarra, designed by the architect and Passivhaus Designer Pedro Mariñelarena Albéniz, together with Itziar Iriarte Zubiría.

This single-family home was designed and built using bio-construction criteria. Outer walls are made of exposed CLT panels, insulated externally with 240mm of wood fibre insulation and natural lime render. A Zehnder Q350 HRV unit provides mechanical ventilation with heat recovery. The timber window frames were supplied by Iribarren, a local manufacturer located in the Navarra region. The house achieved an impressive blower door test of n50 = 0.27 ach. A De Dietrich ALEZIO S 6 MR air-to-water heat pump delivers space heating with underfloor heating, as well as producing domestic hot water.

Description

Praxis has carried out the Passivhaus Premium certification of this single-family home in Sant Pere de Ribes, Barcelona, designed by the architect and Passivhaus Designer Sergi Gargallo of SgARQ Passivhaus Architecture.

The house has a useful floor area of 254 m2 over a ground floor and three upper floors.  The project was developed by reusing an existing structure that remained unfinished, built more than 10 years ago on the same plot, thus reducing the environmental impact of the house.

Outer walls consist of a honeycomb brick with 10cm of high-performance EPS external thermal insulation. The roofs have between 10cm and 20cm of XPS insulation, and the window frames are Passivhaus certified WERU Afino One PVC with triple glazing and exterior shading devices.

An excellent result was achieved in the “Blower Door” air tightness test of n50 = 0.22 ach.

A solar photovoltaic array supplied by Prot Energia was installed on the roof, which generates 11,313 kWh/a of renewable energy. The owner also has an off-site solar photovoltaic installation that generates 10,609 kWh/a, totalling 21,922 kWh/a. The house is expected to consume a total of 6,864 kWh/a.

Through the Passivhaus certification process, Praxis audited all the calculation and design documents presented by the Passivhaus Designer, including the PHPP calculation, thermal bridge calculations, architectural and service drawings and reports, the Blower Door test report, the ventilation commissioning report, and photographic documentation of the entire construction process, to ensure that the building was built as designed and as calculated in the PHPP energy model.
