Low-energy-consumption house

• As everybody knows, buildings consume 1/3 of the primary energy, about the 38% of the energy is necessary to regulate the temperature of our houses and the energy requirement becomes always more important to cool our houses, especially in the regions with a Mediterranean climate.
• Currently it is not possible to increase the internal production but it is possible to intervene on the demand reducing the energy requirement and increasing, at the same time, our quality standards of life.
• The potentiality of the energetic saving in buildings is very large, today we can live in comfortable houses while consuming, at the same time, less energy.

For the first time, we are able to renounce to something increasing significantly our qualitative standard of life and the occasion for that is offered by the energetic saving and the energetic efficiency in our houses and workplaces.
It is a very simple concept, to use little energy for the energetic requirement of our buildings in return of a very great comfort.
This challenge has already been won in locations with the typical climate of North Europe and now it has to be faced in the Mediterranean climate, which presents us with further problems since it is linked to various elements such as variability and seasonal changes, that is, from the cold winter to the very hot summer.
That of the summer heat has become one of the most striking problems, and this requires a bigger demand for energy to cool our houses during the warm season. It is not a case that the biggest demand for energy occurs in summer.
As a consequence, the demand for an inner comfort in summer is always higher because, to the increasing temperatures, it is related a sultry weather because of a big quantity of humidity in the atmosphere.

Therefore, we have two choices:

• Currently, there is a wide use of conditioning and dehumidification systems which require a big quantity of energy with the consequent consumption of a precious amount of electric energy at a high cost, without considering the deriving consequences for the climate.
• More cleverly, to build houses addressed to a summer performance tending to tropicalization.
