Passiv España passes the Blower Door test and heads for Passivhaus Classic certification

The NidoZero self-build in Albacete is fully completed: the envelope performs exactly as designed and only the seal remains.

Passiv España passes the Blower Door test and heads for Passivhaus Classic certification

Construction of Passiv España, the NidoZero self-build development in Albacete, is fully completed. Only one step remains — one of those you cannot see: the Passivhaus Classic certification, which is already underway.

The key milestone of this final phase was the Blower Door airtightness test, passed with a satisfactory result. The envelope performs exactly as designed, guaranteeing the comfort and energy efficiency of the home all year round.

It is the outcome of a construction process where every decision has a clear purpose: light timber framing, ETICS where required and Termoklinker brick by Cerámicas La Paloma. A façade that speaks for itself.

With this project we continue to strengthen our commitment to the Passivhaus standard in Castilla-La Mancha: near-zero-energy architecture — measurable and certified — from the first survey to key handover.
