Another of the innovative homes from House Habitat and 100x100madera is in the final phase of construction. In this case, the challenge is to exceed the requirements established by the Passivhaus Institute of Germany , the most demanding in the world in energy efficiency, in a Mediterranean climate, for a home located a few meters from the beach.

In addition to doing it, as always, using natural and ecological materials that respect the environment and the health of its inhabitants.

Finnish pine wood , from sustainable forests, has been used in the structure . The insulation has been consolidated on this occasion with wood fiber . In order to reinforce the thermal envelope on the façade, a 6 centimeter thick and 265 kg/m3 density wood fiber panel has also been used on which a silicate mortar will be applied as a final finish.

Among the techniques installed to comply with the Passivhaus standard, the double-flow mechanical ventilation system with enthalpic energy recovery and the use of aerothermal energy for air conditioning and domestic hot water stand out. As for the windows, they will be made of laminated wood with double glass, warm edge , solar control and argon gas in the chamber, with an average installed window transmittance of 1.37 W/m2K.

The house will also be equipped with home automation technologies to control the air conditioning, ventilation and blinds through mobile devices connected to the Internet .

The air conditioning system has temperature sensors on each floor and will automatically act on the water coil of the air conditioning system to provide the necessary cold or hot air and thus maintain the expected comfort conditions.
