La casa passiva è un'abitazione che assicura il benessere termico senza alcun impianto di riscaldamento "convenzionale", ossia caldaia e termosifoni o sistemi analoghi.
The house is called passive because the sum of the contributions of passive heat of solar radiation transmitted through the windows and the heat generated from appliances within the building and the occupants themselves are almost enough to offset the losses of the housing during the cold season.
This type of construction is usually made of wood structural , which is a natural insulator.
The energy needed to balance the heat of the building is typically provided with non-conventional systems (eg solar panels or heat pump per riscaldare l'aria dell'impianto di ventilazione controllata a recupero energetico ).
L'impianto di riscaldamento convenzionale si può eliminare se il fabbisogno energetico della casa è molto basso, convenzionalmente inferiore a 15 kWh al m² anno . Queste prestazioni si ottengono con una progettazione molto attenta, specie nei riguardi del sole, con l'adozione di materiali isolanti ad altissime prestazioni su murature perimetrali, tetto e superfici vetrate e mediante l'adozione di sistemi di ventilazione controlled energy recovery . Nate
in Sweden , passive houses are primarily distributed in Germany and Netherlands and other northern European countries.
So-Smart homes passively.
cost? Yes ... .. but with less investment and innovation in a few years further reduce costs ...
The use above all, by statute, the Nordic countries as well as save them .. because what little sun there is the use ...
In Italy? No No. .. our government are too busy taxing the suv ... to discuss large coalitions to fuck better ... and us? No. .. no ... we keep our houses of brick, rustic expensive, but beautiful all the same ... ... it seems that new housing construction in Italy do all the cookie-cutter and a layer of cement ... then just embellish them with two glass and resin crap .. just to see that our architect of the loan is a futuristic .... then ... we pay our bills to the taste of expensive oil, but we buy fair trade and our car is € 4 ...
