Simple, like the elements that comprise: wood, glass, iron and stone. Simple as the idea of \u200b\u200bharnessing the contribution is free of the sun, thanks to a large solar panel, is geothermal energy, using an electric heat pump .
The desire to build a detached house in modern and comfortable for her daughter became a father for the manufacturer in a challenge and has resulted in a villa with all amenities in a quiet residential area Calcinate , a few km from Bergamo. For
Constant Vavassori , a holder of VIESSE Snc, a company which has more than thirty years experience in the construction industry - the need for renewable energy sources and materials which guarantee high performance isolation was born during a stay in Freiburg , pleasant city situated in southern Germany and known as Solar Stadt, or the "Solar City" . A non-random
epithet.
Freiburg has one of Europe's largest solar sensors and the most important center of European research on solar energy (Fraunhofer Institut) and has become a reference for the sector to high environmental performance.
A rich and stimulating journey that has dragged Vavassori constant in this bet on the border with the experiment: to build a detached house for her daughter that it meets the strict parameters of CasaClima Class A (a questa classe appartengono gli edifici con un consumo annuo inferiore a 30 kWh/mq) , che utilizzi gli apporti gratuiti del sole e dell'energia geotermica, evitando emissioni di CO2 e che sia interessante anche dal punto di vista architettonico.
L'edificio è in grado di esprimere originalità e semplicità minimale.
Si tratta di due volumi giustapposti: uno, orientato a sud, è caratterizzato da ampie vetrate che donano luce agli ambienti e ottimizzano gli apporti solari in inverno.
L'altro volume, orientato a nord, è interamente rivestito da piccoli blocchi in marmo che hanno una funzione termoregolatrice degli ambienti interni.
I due volumi sono bilanciati da un insieme di aggetti e schermature che easily solve the overheating of the structure during the summer.
Particular attention was dedicated to isolation.
The building is entirely made of wood conglomerate Isotex blocks and cement, a solution that provides thermal transmittance of less than 0.26 W / mqK, while the expanded polystyrene (EPS) - a highly insulating material, economic and Lightweight - has been used for the outer coating.
also under construction, the construction company has the best care and the cancellation of thermal bridges.
Even the windows, made of wood okumè coated aluminum exterior, have a mean thermal transmittance of 1.2 W / mqK. We are now in the utility room, plant the very heart of the house. Two geothermal
reaching a depth of 90 m to provide geothermal electric heat pump, capable of producing hot water, heating in winter and cooling in the summer, through a radiant floor panel system. A dehumidification system
RDZ , prevents the formation of condensation when, during the summer, how the air conditioning is on.
addition, the villa has a controlled ventilation system with heat recovery to extract the most polluted air retaining heat energy.
Il gruppo di areazione, di produzione olandese Zehnder, fornisce aria fresca in quantità regolabile ai sistemi di distribuzione locali. L'impianto fotovoltaico, vero segno distintivo della villetta, è realizzato con moduli HIT Sanyo.
Con la sua potenza installata di 4.1 kWp, è collegato in rete e beneficia degli incentivi del Conto Energia.
La combinazione di pompa di calore elettrica e impianto fotovoltaico rende superfluo l'allacciamento alla rete gas, con considerevoli risparmi di emissioni e in bolletta.
Dopo questo esperimento, riuscito, Costante Vavassori intende diffondere su larga scala altri edifici intelligenti, alcuni già in fase di realizzazione, con standard minimo CasaClima Classe A.
