Description

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.
