There are various forms of sustainable construction, among which prefabricated wooden houses and passive houses stand out.
These options represent viable ecological alternatives for those who wish to build a sustainable dwelling in Portugal.
Modular and Prefabricated Wooden Houses
A modular wooden house is a type of prefabricated dwelling built off-site, in a factory, by assembling several modules.
These modules are then transported and assembled on-site, without the need for heavy machinery.
This type of construction is generally more economical than the traditional model (between 10% and 30% cheaper), has a reduced construction time (between 10 days and 6 months) and generates less waste during construction.
The modules are manufactured in a controlled environment, which reduces the risk of material deterioration.
Therefore, it is an excellent option for those who wish to build an ecological house in Portugal.
Passive and Energy-Efficient Dwellings
The concept of low-energy consumption buildings emerged in the 1970s, following the oil crisis. At that time, there were already studies on highly insulated dwellings and passive solar constructions, which served as the basis for the development of the concept of passive houses in the 1990s.
The first passive house was built in 1991, in the city of Darmstadt, Germany, where the Passive House Institute (PHI) is located — an independent research center directed by Dr. Wolfgang Feist. This institute is responsible for training construction professionals in the concept and principles of passive houses.
