A house built with Passivhaus certification or Passive House (in english) is a type of house created to maintain ideal atmospheric conditions and comfort in its interior, resulting in annual energy savings of between 70% and 90% compared to a conventional house.
These constructions have optimal thermal insulation in their exterior walls, high performance doors and windows with thermal bridge break and mechanical ventilation with double flow heat recovery that guarantees the quality of the interior air without the need to ventilate by opening windows.
