Passivhaus or passive houses are homes that have a high level of thermal comfort . This, despite having very low energy consumption, making them homes with great energy efficiency . Below we tell you all the keys you should know about a passive house . The concept of passive houses began in the US in the s. There, a construction model of zero energy consumption was investigated where the energy consumed was that generated by the home. To do this, the climate (temperature and humidity), solar radiation and wind were taken into account.
These are determining factors in location, design, orientation, thermal insulation and ventilation. In Spain we also have various passive houses. The development of the Passivhaus concept ( passive houses ) continued in Germany in the early s. It happened when professors Bo Phone Number List Adamson and Wolfgang Feist proposed that there could be efficient buildings that were more energy sustainable than traditional ones. For this reason, they created the Passivhaus standard that certifies the Passivhaus Institute and guarantees a class A energy certification with its certification.
The first passive building was made in Darmstadt (Germany) with the passivhaus standard . It had an energy consumption below kWh/m for heating. At first, the profitability of passive houses was much considered . Their construction involved a great cost, despite all the benefits they have. As time went by, technology advanced and the price of passive houses became cheaper. Even so, it must be taken into account that although its construction is more expensive initially, it pays for itself thanks to the energy savings resulting from an energy bill much lower than that of a traditional home.
