The concept of Passive House, or energy efficient building, refers to a standard of construction of a home with the following features:

Origin of Passive House

It is important to understand that Passive House is not a brand, but an efficient construction concept. This construction concept that appeared already in the early 80s.

Back then, there was already a talking about the use of bioclimatic architecture for home construction. In detail, the study of the climate of the area where the house was going to be built (taking into account sunny days, rain, the surrounding environment, etc.) was used to make the most of them with their orientation and design.

That, together with the use of materials and construction procedures as ecological and efficient as possible for that environment, results in a house with ultra-minimal energy consumption.

How much you save on energy consumption with a Passive House

The concept of passive house goes far beyond of what we usually consider when we talk, for example, about energy rating labels in buildings.

When the building process is done following Passive House standards, there are important energy savings, like:

Advantages of a Passive House

Taking it toegether, we can say that the advantages of this building system are:

The international standards of the Passive House, its history and its expansion

In order for a house to be considered passive, it must meet the standards that arose following a collaboration between Wolfgang Feist, from the German Building and Environment Institute and Bo Adamson, from Lund University in Sweden.

The first house that met that standard was built in Darmstadt, Germany, in 1990. The Passivhaus-Institut would be born there, six years later, which controls that standard to get houses with that 90% reduction in energy consumption. Germany, Austria and the Nordic countries are the pioneers in Europe in terms of passive houses.

In the early 2000s, the Passive House concept crosses the ocean and the first passive house in the United States is built in Urbana, Illinois, in 2003.

Passivhaus-certified materials are marketed and, currently, due to the greater ecological awareness, the fight against climate change and the price of energy, the concept of passive house is more in vogue than ever.

As we can see, a good construction standard allows savings of up to 90% and total respect for the environment surrounding the house. Therefore, the Passive House concept will become increasingly important in a world of clean energy and responsible consumption.
