Pasivhause homes :: Reynalco

The passivhause concept is based on building constructions that have great thermal insulation, rigorous infiltration control, and maximum indoor air quality, as well as taking advantage of the sun's energy for better air conditioning, reducing energy consumption in the order of 70 % (on conventional constructions).
Advantages of the Passivhaus building in Mediterranean climate

The Passivhaus house has a very low energy consumption for heating and cooling. Compared to the current regulations in force in Germany, it spends approx. 80% less energy for your thermal conditioning. Passivhaus Spain, since Spain has a less severe climate, an improvement of 60% could be reached compared to the standard consumption of a new building, and the best possible energy classification would be achieved: class A.

According to the definition of the European research project "Passive-on", the Passivhaus house in the Mediterranean climate has to meet the following conditions:

 . Maximum useful energy demand for heating, 15 kWh / m2 year.
 . Maximum useful energy demand for cooling, 15 kWh / m2 year.
 . The outer envelope of the building must not have a tightness greater than 0.6 volumes / h (measured with a pressure of 50 Pascals).
 . Maximum primary energy consumption for heating, cooling, domestic hot water (DHW) and electricity, 120kWh / m2year.
