PASSIVE HOUSE: CONSTRUCTIONS INVESTING IN SAVINGS
What is a Passivehaus?
They are energy efficient buildings, with high interior comfort and maintaining very low energy consumption, which implies a significant saving in the energy bill.
La Passive House (passive house) is based on design criteria that allow a great thermal isolation, a rigorous control of infiltrations and a maxim indoor air quality, in addition to taking advantage of the sun's energy for better air conditioning.
ADVANTAGES OF PASSIVHAUS
- Comfort. The high level of comfort it provides users allows them to live in a warm environment in winter (20ºC), no cold radiation from the facade or discomfort from drafts, and, at the same time, a very pleasant atmosphere in summer (<25ºC).
- Health. Ventilation system, blowing fresh and clean air imperceptibly and constantly, provides the user with a high quality of indoor air by filtering the 90% from pollens and harmful particles that can be found in the air.
- Saving. The energy savings it provides to users have a direct impact on savings in the bill of a 85-90% for heating and air conditioning compared to a conventional home.
- Ecology. Three arguments that allow the creation of an environmentally friendly future: energy saving, considering that the 40% of the energy consumed in the EU corresponds to buildings. The use of ecological materials and renewable energies.
A PASSIVEHAUS home must pay attention to:
- Reduce air leaks. It is necessary to carry out a special test of air impermeability in the house (Blower Door Test).
- Superior thermal insulation.
- Thermal bridges break: Do not interrupt the insulation layer.
- Take care of the joints between construction elements.
- High performance windows and doors.
- Efficient and balanced ventilation systems. Mechanical ventilation with heat recovery required.
