In the county of Tessin, very few low energy houses have been constructed in comparison to the German part of Switzerland, although the climate is rather temperate and sunny in winter. The "Vitali-Velti house", located in the village of Monte Carasso near Bellinzona, is designed to be a low energy house.The main objectives of the project are to establish a monthly heat balance of the house, assess the thermal comfort, assess the house in the view of sustainable development and perform an economical analysis to compare the house with a conventional solution. This project is chosen to serve as an example for the IEA Solar Task 28 "Solar Sustainable Housing". The results will also contribute to both the promotion of low energy houses in Tessin and for Minergie information. Measurement results and analysis showed that both house A and house B are conform to the new SIA 380/1 norm and they both satisfy the Minergie standard.

In the Tessin county, few low energy houses have been constructed compared to
the German part of Switzerland. The two-family house “Vitali-Velti” is one of the few
examples. It has been monitored and is documented in this study. Thanks to large windows in the south-east façade and a well insulated building envelope (insulation thickness of 13 – 20 cm and special attention given to reducing thermal bridges), the passive solar gains significantly contribute to heating. The remaining heating requirement is covered by a closed chimney and sometimes with an electric radiator. Heat is distributed by free convection inside the house, thanks to openings between the stairs. A double flux ventilation system with heat recovery
ensures the air change (3 volumes per day). Each house has a solar hot water
system (2 x 4 m2 of solar collectors) with electric auxiliary energy. House A has a
heating reference area of 260 m2 and house B 234 m2.

Dans le canton du Tessin, peu de maisons à basse consommation d’énergie ont été construites relativement à la Suisse allemande. La maison bi familiale « Vitali-
Velti » est l’un des quelques exemples. Elle a pu être monitorée et documentée dans cette étude. Le concept de la maison permet, grâce à de grandes fenêtres orientées au sudest et à une isolation soignée de son enveloppe (épaisseur de l’isolation variant entre 13 et 20 cm, ponts thermiques coupés), d’exploiter au mieux les gains solaires passifs. L’énergie de chauffage restante est couverte par une cheminée fermée et, parfois, par un radiateur électrique. La distribution de la chaleur se fait par convection naturelle de l’air dans la maison, grâce à des ouvertures entre les étages. Un système de ventilation douce à double flux avec récupération de chaleur permet d’assurer le renouvellement d’air (3 volumes par jour). L’eau chaude est préparée avec un chauffe eau solaire (« kit » solaire) dans chaque maison (2 x 4 m2 de capteurs). L’énergie d’appoint est électrique. Les surfaces de référence énergétique des maisons A et B sont respectivement 260 m2 et 234 m2.

Nel cantone Ticino, sono state costruite poche case a basso consumo energetico rispetto alla Svizzera tedesca. La casa bifamiliare “Vitali-Velti” è un esempio di questo tipo d’abitazione ed è stata monitorata e documentata grazie a questo progetto di ricerca. Il concetto della casa permette, grazie alle grandi finestre orientate verso sud-est e un involucro ben isolato (spessore dell’isolamento compreso tra 13 e 20 cm, tagli termici), di sfruttare al meglio i guadagni solari passivi e limitare al minimo le perdite per trasmissione. L’energia di riscaldamento necessaria è fornita da un caminetto chiuso e sporadicamente da un radiatore elettrico supplementare. La distribuzione di calore nella casa è assicurata dalla convezione naturale dell’aria, che può circolare attraverso aperture tra i piani. Un sistema di ventilazione automatico a doppio flusso con ricupero di calore permette di garantire il ricambio d’aria (3 volumi al giorno). L’acqua calda è prodotta da uno scaldacqua solare (“kit” solare) in ogni casa (2 x 4 m2 di collettore solare). L’energia ausiliare è elettrica. Le superfici di riferimento energetico delle case A e B sono rispettivamente di 260m2 e 234 m2.
