In recent years, passive houses<\/strong> have become one of the most demanded options in the construction of single-family homes in Spain<\/strong>. More and more people are looking for an efficient<\/strong>, comfortable house<\/strong> with almost zero energy consumption, and this is where prefabricated passive<\/strong> houses and the Passivhaus<\/strong> standard come into play. <\/p>\n\n

What are Passive Houses or Passivhaus?<\/h2>\n\n
\"What<\/figure>\n\n

Passive houses, also known as Passivhaus houses<\/strong>, are homes designed and built under an international standard born in Germany whose main objective is to minimize energy consumption<\/strong> without sacrificing comfort.<\/p>\n\n

Unlike a conventional house, a passive house<\/strong> maintains a stable indoor temperature throughout the year thanks to its design, orientation and construction systems, reducing energy consumption by up to 90%<\/strong>.<\/p>\n\n

This concept applies to a detached single-family house<\/strong>, a semi-detached single-family house<\/strong> or even a prefabricated single-family<\/strong> house.<\/p>\n\n

Basic characteristics of passive houses<\/h2>\n\n

For a house to be considered Passivhaus, it must comply with a series of very specific technical principles:<\/p>\n\n

1. High-performance thermal insulation<\/h3>\n\n

Prefabricated concrete passive<\/strong> houses stand out especially in this point, since concrete offers high thermal inertia<\/strong>, helping to maintain a constant interior temperature.<\/p>\n\n

2. Elimination of thermal bridges<\/h3>\n\n

In the construction of passive houses<\/strong>, care is taken at all construction joints to avoid heat or cold losses.<\/p>\n\n

3. High-performance carpentry<\/h3>\n\n

Triple-glazed windows and doors with highly efficient frames.<\/p>\n\n

4. Air tightness<\/h3>\n\n

The housing envelope must be completely watertight to avoid uncontrolled leaks.<\/p>\n\n

5. Mechanical ventilation with heat recovery<\/h3>\n\n

One of the key systems of passive houses<\/strong>, which allows to renew the indoor air without losing energy.<\/p>\n\n
