Prefabricated homes are undoubtedly a growing trend in the Spanish real estate market. This emerging building model offers homes of all sizes to suit any budget, from those on the most modest budgets to those willing to pay €350,000 for a true luxury villa. However, in recent years a new concept has emerged: passive modular homes , or Passivhaus . But what are they, how do they work, and most importantly, what do they cost?
The most significant difference in these innovative modular designs is their increased efficiency . In fact, their energy consumption achieves maximum reduction , although they are characterized by additional triple-glazed exterior insulation and motorized blinds. Furthermore, if renewable energy sources such as solar panels are included, a net positive energy consumption of 15 kWh per square meter per year or less could be achieved . Therefore, more energy is generated than is consumed in maintenance and daily operation. This is all the more impressive considering that in a traditional house, this figure exceeds 100 kWh per square meter per year.
Furthermore, they incorporate the new requirements of the Technical Building Code, a public body under the Ministry of Transport, Mobility and Urban Agenda that regulates compliance with nearly zero-energy consumption parameters for all new construction. This represents a significant source of savings on bills such as electricity and gas, especially considering that current utility prices are sky-high.
What are the benefits of a passive prefabricated house or PassivHaus?
One of the main benefits of Passivhaus-certified homes is energy savings. This is achieved thanks to their triple thermal, acoustic , and electrical , which creates comfortable indoor conditions with minimal energy consumption.
Furthermore, due to its high energy efficiency, it is characterized by the high degree of well-being of its inhabitants, especially due to the optimal conditions of thermal comfort and its construction without damage to nature.
What is the Passivhaus certificate?
The Passivhaus certification standard refers to homes included in the list of passive houses that meet a series of sustainability requirements. It was created by Professors Bo Adamson of Lund University in Sweden and Wolfgang Feist of the German Institute for Building and Environment, who founded the Passivhaus Institut (PHI) in Germany in 1994. Anyone can apply for certification as long as they meet the requirements set by the organization.
How much does a passive house cost in Spain?
Regarding the production costs of a passive prefabricated house, in the case of the Spanish company American Building System or ABS, a leader in the manufacture, distribution and sale of this type of environmentally friendly passive prefabricated houses, they have a starting price of 1,400 euros + VAT (10%) per square meter.
According to sources consulted by this publication at the Guadalajara-based company, the average size for this type of Passivhaus construction is typically 120 square meters. Therefore, the final price would be estimated at €168,000 plus VAT. However, as with any individual case, the final budget will depend directly on the potential client's choices, including the model, building size, and materials selected.
