Passive Housing Is Recovering From The Epidemic Due To Its High Energy Efficiency

The epidemic shows that many of the houses built in Spain for decades are poor. Millions of souls spent months in energy filters, ventilation and filtration problems on the floor, and poor indoor air quality.

However, there is another way to build a house. It has been 30 years since Wolfgang Feist, a German physicist and astronomer, built the world’s first passive house in Darmstadt, Germany, in 1991. Today, he is one of the most famous efficient building experts in the world. Fester realized that more than a third of his energy consumption came from heating, and he began to study heat distribution, windows, roofs and ventilation systems… Their house consumes 87% less energy than a traditional house.

Passive housing has high degree of insulation, no thermal bridge and good external air sealing, which can ensure the minimum energy demand. “It’s amazing that what virologists are suggesting now is almost exactly what we’ve been saying for 30 years. Fester, who lives with his family at his home in Darmstadt, replied by e-mail: “in the early stages of development, we have always had the health and well-being of our residents in mind.”.

For the founders of the passive house Institute and international (voluntary) standards, covid-19 has similarities with the global climate crisis. First, building energy conservation is not negotiable.

Since 2012, the European Union has been striving to achieve this goal, when it issued a directive requiring that since January 2021, the energy consumption of all new residential buildings should be almost zero. The same is true in Spain, which helps to increase interest in such passive housing and certificates such as Feist, but it must be remembered that this is not the only one that exists and that architects and developers can turn to it.

Focusing on the seal of German physicists, it has more than 29000 real estate certificates in the world, covering an area of nearly 2.7 million square meters. This includes housing, schools, nurseries and offices. The first passive hospital is being built in Frankfurt.

In Spain, the first passive house was built in October 2010 in moraleda de zafayona, Granada. “Since then, there have been more and more projects in Spain and a lot of architects and engineers working on it,” fester said.

“In the past two years, we have proved the same size as the previous eight years, and will double in the next two years,” said Bruno Guti é rrez Cuevas, President of passiphaus, a construction platform, the world’s second largest partner Association (more than 800), after Germany. Gutierrez added: “with the outbreak of the epidemic, many people have found that there are building methods that can save energy and ensure greater indoor comfort, which is why we get more consultation than before.”. However, it warns of an increase in fraud by companies that provide passive devices when they do not meet the requirements.

In Spain, more than 158000 square meters of certified area are distributed in 150 projects. It is expected to reach 387000 meters in the next two years, with 307 properties. They include a house in the city of San Andrews de la Barca in Barcelona. They say it is the most sustainable in Europe because it has passiphaus advanced certification (from the passive Housing Institute) and five green leaf seals (from the Spanish Green Building Council). At present, only 19 housing units in the world have passed the prototype certification of the first housing unit and the second housing unit.

“In its four walls, the noise of the car is invisible, there is no air flow, and the temperature does not vary from room to room. Stefano Carlo Ascione, arquima’s architect and passive architecture expert, explained: “this is a house with a constant indoor temperature between 22 and 24 degrees. It’s always quiet. You can’t even hear rain or storms.”. The house, built from an industrial system, generates four times as much energy as photovoltaic panels. “Compared with houses built under the 2006 building technical code (CTE), the energy efficiency of arquima founder Jos é Antonio Gonz á lez is more than 90%, and with the update of CTE on January 1, the energy efficiency reaches 50%,” said arquima founder Jos é Antonio Gonz á lez

The real challenge in Europe, though, is the millions of energy inefficient homes that have been built. 75% of EU parks are. That’s what fester recently did at the darmstadts. “We are studying the application of energy-saving technology, especially the modernization of existing buildings. There is great potential to improve efficiency in this area. ”

In Spain, the government plans to invest 5.3 billion euros from European funds to repair the Spanish real estate market. The task is arduous. According to a study by the National Association of ceramic and building materials dealers (andimac), Spanish homeowners will have a quality of life score of 6.8 by 2020. This is not a suspense, but there is evidence that Spaniards are not satisfied with their homes. About 40% of Spanish households do not have the benefits to help their residents.

Andimak is not surprised by this dissatisfaction, because the aging of Spanish parks worsens at a rate of 2% every year, and rehabilitation affects only 0.15% of them. 83% of families are over 18 years old, which is reflected in comfort and well-being. The most neglected categories are acoustic comfort, thermal comfort and health. “These are below average factors,” they told the association, followed by space design, accessibility, energy efficiency and light comfort.
