Passivhaus Certification, ‘Plus’ for the new Kömmerling Zero Consumption Headquarters
We have achieved the Plus level in PassivHaus certification for the Kömmerling Zero Consumption Building. This certification ensures a very strong envelope, minimizing thermal bridges and guaranteeing airtightness, as shown in the Blower Door tests results (n50=0.40 [1/hour]). Active strategies are also implemented, such as mechanical ventilation with high-efficiency heat recovery and aerothermia for radiant flooring. Finally, photovoltaic panels on the roof allow the condition of zero consumption building.
