What is a Passive House?

Starting as an experiment, great credit can be given to this pioneering project by Professor Wolfgang Feist: at a time when only very few people thought about climate protection, it paved the way for energy efficiency in buildings. A building standard that is truly energy efficient, comfortable, affordable and ecological at the same time. Today, the Passive House Standard has been implemented throughout the world and shines particularly brightly in beacon projects globally.

Passivhaus is a German construction standard for almost zero consumption homes, known in Spain as a passive house. It is the most demanding construction system in the world in terms of energy efficiency. They are homes of the highest quality, with great thermal comfort and almost zero energy consumption. The only internationally recognised, performance-based energy standard in construction.

The Passive House Standard stands for quality, comfort and energy efficiency. It is great for energy efficiency in a building, which reduces the building’s ecological footprint. It manage to reduce heating and cooling needs by up to 75%, the little additional energy they require can be easily covered through renewable energy, making it a home with a very low energy cost for the owner and the planet.

Passive building achieves energy efficiency primarily through an airtight envelope (the physical structures like walls, roofs, and windows that separate the exterior and interior of a building). In order to maintain consistent and comfortable indoor temperatures throughout the year, passive buildings use high-performance windows, extra insulation, and consider window orientation in their design.

Passive House is probably the worldwide leading standard for energy efficient buildings. There are 3 grades of classification in passivhaus constructions: classic, plus and premium. This villa has a passivhaus premium classification since it has a demand for primary energy well below 15kwh/m2.year in addition to having a primary energy production system using photovoltaic solar tiles, reaching practically zero consumption.
