More time at home, forced by the pandemic COVID-19 has opened the eyes of many Spanish residents, who therefore want to improve their homes' health, comfort and safety. One way to make this right is through "passive house" or passive house, a change that saves money in the long run. properties for sale in qatar
The first question you might ask is what is the meaning of passive housing? Basically, passive houses are a highly energy-efficient building standard that promotes energy efficiency, comfort, value for money and ecological ease as well. Established by the Passivhaus Institute in Germany, passive houses are not a particular property or a brand name, but are indeed a building concept: the property simply requires a number of criteria to achieve the passive house standard.
The increased firmness of houses and thermal and acoustic insulation or the requirements for ventilation in properties that meet the passive house standard therefore open up a new horizon for architecture.
Can we spend less money in our houses for energy and heating now that we spend most of our time there? Containment and teleworking have increased the common household consumption bill for many workers. One good way to save money is to apply the highest insulation standards to our homes, where the passive house standard is the most important reference.
This is not only the case because of the good heat insulation, high carpentry quality, triple glazing windows, low transmittance and correct installation, to prevent the formation of thermal bridges, but also because of the mechanical ventilation system with thermal recovery.
"Generally, this type of building achieves, in terms of the temperature, moisture and concentration of CO2 and other pathogens and pollutants, much healthier and more comfortable interior space on the one hand and, on the other, an energy saving of between 60% and 90%," says Sto, a thermal insulation systems manufacturer for the facades and interiors, and one of the other.
The latest change to the CTE (Technical Building Code) will bring the new energy efficiency standard closer to the demanding standards of airtightness, insulation and ventilation of the passive home standard.
"The new requirements of CTE, effective from the beginning of July, are perfectly complemented by numerous requirements of the passive house certificate, making it easier to progress with this certificate in Spain. At present, this seal is much stricter than the CTE and great differences remain. These include requirements for thermal comfort, airtightness, mechanical ventilation and thermal bridges in the summer ", adds the German company that also has a Spanish base.
It naturally improves air quality in indoor environments, now important in preventing the spread of COVID-19. Double flow mechanical ventilation in a building with this standard can contribute to reducing the risk of contagion in closed areas. "The reason for that is the ability to remove the stale air from the inside and simultaneously filter the external air supply and also remove contaminating elements. This ensures the best indoor air quality throughout the year, "Experts say. Experts say.
Finally, they stress that a property built to the "Passivhaus" standard (in the event of renovation, known as "EnerPhit") adds greater value to the property. According to the International Real Estate Federation (FIABCI), 20% more than a normal house could be appreciated as a passive house.
