The term Passive House (or "passive house") has revolutionized architecture and construction in Europe and around the world. But what exactly is Passivhaus, and why is it increasingly relevant for architects, developers, and homeowners committed to energy efficiency and sustainability?
What is Passivhaus?
Passive House It is an international construction standard created in Germany in the 90s, whose objective is to achieve buildings with extremely low energy consumption, superior thermal comfort and excellent indoor air quality.. It is not a trademark, but a methodology endorsed by more than 25.000 buildings built under its principles around the world..
Key principles of the Passivhaus standard
The success of the Passivhaus concept is based on five fundamental principles:
-
High quality thermal insulation: Walls, roofs and floors with high insulation capacity to maintain stable temperatures.
-
Air tightness: A highly airtight enclosure that prevents uncontrolled air leaks.
-
High performance windows and doors: Triple glazing and frames with thermal break.
-
Elimination of thermal bridges: Construction details that avoid weak points where energy is lost.
-
Mechanical ventilation with heat recovery: System that renews indoor air and recovers energy from the extracted air, ensuring air quality and efficiency.
Benefits of a Passivhaus house
-
Energy saving: Reduces energy consumption for heating and cooling by up to 70-90% compared to conventional buildings.
-
Thermal and acoustic comfort: Stable interior temperatures and absence of drafts, with excellent insulation against outside noise.
-
Health and air quality: Controlled ventilation that eliminates moisture and contaminants, improving the well-being of occupants.
-
Sustainability: Minor carbon footprint and higher long-term resale value.
What requirements must a Passivhaus building meet?
According to the standard, a Passivhaus home in a Mediterranean climate must meet these parameters:
-
Maximum heating demand: 15 kWh/m² year
-
Maximum cooling demand: 15 kWh/m² year
-
Maximum primary energy consumption: 60 kWh/m² year
-
Air tightness: ≤ 0,6 renewals/hour
Ventilated facade and Passivhaus: the perfect combination
La ventilated facade It is one of the construction systems most recommended for Passivhaus projects. It allows for continuous external insulation installation, eliminates thermal bridges, and improves the building's durability and comfort. At CELO Façades, we have over 30 years of experience designing and supplying certified fixing systems for ventilated façades, compatible with Passivhaus requirements and with up to a 15-year warranty..
"Our systems are certified to the most demanding standards, including the European Technical Assessment (ETA) and CE marking, ensuring maximum reliability and safety in high-energy efficiency projects."
Why choose Passivhaus?
The Passivhaus standard is not just a trend, but an effective response to the challenge of sustainability and comfort in buildings. Embracing this model means investing in quality of life, savings, and the future.
Do you have a project in mind and want to know how a ventilated façade can help you comply with Passivhaus?
