A Passive House represents a building standard that is exceptionally energy-efficient, comfortable, economically viable, and eco-friendly all at once. It is not a brand name but a construction concept open to everyone and has proven successful in practice. Significantly, a Passive House consumes 90% less heating energy than traditional buildings and saves more than 75% compared to average new constructions, with its heating energy consumption as low as approximately 1.5 liters of heating oil equivalent per square meter per year. This efficiency is achieved through special windows and highly effective thermal insulation, keeping heat within the house and utilizing internal energy sources like body heat or solar gain, simplifying heating needs. Moreover, the living comfort in a Passive House is substantially enhanced by a ventilation system with highly efficient heat recovery, ensuring fresh air without drafts and maintaining high surface temperatures for thermal comfort. In Central Europe, where traditional buildings typically rely on central water heating systems, the Passive House concept reduces heat loss to such an extent that conventional heating is unnecessary, with any required "residual heating" easily supplied through the ventilation system's air supply, defining a Passive House by its lack of traditional heating and cooling systems.
A comfortable indoor climate must be achievable without a separate heating system or air conditioning: For this, the annual heating demand according to the Passive House Planning Package (PHPP) must not exceed 15 kWh/(m²a).
Comfort criteria must be met in every living space during winter and summer. This generally results in the following component qualities:
The demand for renewable primary energy (PER, according to PHI methods) for all household applications (heating, hot water preparation, and household electricity) combined must not exceed 60 kWh/(m²a). The calculation is carried out according to PHPP.

A Passive House is designed to be ultra-energy-efficient, providing superior comfort, air quality, and durability while significantly reducing energy costs.
The duration can vary based on project complexity, but we streamline the process to make it as efficient as possible, typically ranging from a few months to a year.
We aim to provide a design process that is highly flexible, ensuring your vision comes to life without compromising on efficiency or aesthetics. However there are limitations if your house has a complex exterior geometry.
Absolutely. The initial investment is offset by substantial long-term savings on energy costs, not to mention the increased comfort and health benefits.
Many homes can be upgraded to meet Passive House standards. This certification is called EnerPhit. We offer consultations to assess the feasibility and outline the necessary steps.
