You can’t realize a passive house without design and technical skills, without taking careful attention to detail, without being accurate in all stages of building and without a guarantee of professionalism.
Design is one of the principal parts. Above all, it is a good practice to analyze the energy performance of the building site, like its orientation, if there are obstacles to sunrays, the action of wind. This must be done to find the best way to position the house to obtain a “nearly zero energy” building, with reduction of energy dispersion. As you can see, Villa Manzano has a compact shape and this is very important because heat dispersion depends on the external contact of surfaces. So less surface on the outside means less heat dispersion during cold seasons.
A passive house doesn’t have a conventional heating plant. The insulation of its structure and the excellent location on the ground makes it possible to use controlled mechanical ventilation with a post heating battery for air, connected to horizontal geothermal probes. The sanitary water production comes from a dedicated heat pump and from a hydronic stove situated in the central area of the house. The stove send 90% of heat to water and 10% to air.
The villa is about 150 sq mts, two level . On the ground floor there is a wide open space living room and kitchen together, then a bathroom and the central heating plant. On the first floor there are three bedrooms and another bathroom.
