Le Groupe Trecobat va construire une maison exp\u00e9rimentale en milieu chaud : la Villa OCCITAN-E. Cette maison est la seconde du Groupe en lien avec le projet national COMEPOS. Les travaux de construction vont d\u00e9marrer en septembre 2017 et s\u2019\u00e9chelonner jusqu\u2019\u00e0 mars 2018.<\/strong><\/p>\n

Ce prototype de maison individuelle devra r\u00e9pondre aux contraintes d\u2019un climat \u00e0 fortes amplitudes thermiques \u00e0 travers 3 axes de d\u00e9veloppement :
\n\u2022 le confort et la sant\u00e9 pour l\u2019habitant ;
\n\u2022 la sobri\u00e9t\u00e9 \u00e9nerg\u00e9tique ;
\n\u2022 la ma\u00eetrise du co\u00fbt de construction et de fonctionnement de la maison.
\nLes travaux de recherche et d\u2019exp\u00e9rimentation seront effectu\u00e9s par des \u00e9quipes R&D de Trecobat, du CEA et des partenaires industriels associ\u00e9s au projet.<\/p>\n

L\u2019un des challenges majeurs que s\u2019est fix\u00e9 Trecobat pour sa maison Comepos de Toulouse est d\u2019installer une solution saine et \u00e9nerg\u00e9tiquement sobre d\u2019abaissement de la temp\u00e9rature int\u00e9rieure lors de fortes chaleurs. Les m\u00e9thodes de rafra\u00eechissement vont s\u2019inspirer des habitats traditionnels des climats m\u00e9diterran\u00e9ens pour apporter un confort naturel : un rafra\u00eechissement par la structure de la maison (plafond, murs) associ\u00e9 \u00e0 une ventilation naturelle, le tout pilot\u00e9 automatiquement et sans qu\u2019il soit n\u00e9cessaire d\u2019insuffler de l\u2019air froid artificiellement.<\/p>\n

Une combinaison de plusieurs technologies tr\u00e8s performantes :
\n\u2022 un plafond rayonnant rafra\u00eechissant coupl\u00e9 \u00e0 des sondes g\u00e9othermiques ;
\n\u2022 un syst\u00e8me de ventilation naturelle de l\u2019air int\u00e9rieur, d\u00e9j\u00e0 inscrit dans un programme d\u2019exp\u00e9rimentation par Trecobat et le CEA dans une maison test \u00e0 ossature bois \u00e0 Cadarache ;
\n\u2022 une VMI\u00ae (Ventilation M\u00e9canique par Insufflation) qui acc\u00e9l\u00e8rera la puissance de la ventilation naturelle tout en \u00e9vacuant les polluants et assurera la qualit\u00e9 de l\u2019air par un renouvellement permanent ;
\n\u2022 des syst\u00e8mes d\u2019occultation passive de la chaleur solaire (vitrages \u00e0 contr\u00f4le solaire) et active (pilotage intelligent des volets roulants) ;
\n\u2022 des fen\u00eatres motoris\u00e9es pour la ventilation naturelle.<\/p>\n

Le surco\u00fbt d\u2019installation de ces technologies sera compens\u00e9 par les \u00e9conomies r\u00e9alis\u00e9es dans le cadre contraint de sobri\u00e9t\u00e9 \u00e9nerg\u00e9tique de Comepos, soit une r\u00e9duction de consommation de 20 % par rapport aux solutions traditionnelles de refroidissement par climatiseur. La consommation d\u2019un climatiseur revient \u00e0 un co\u00fbt moyen de 250\u20ac\/an, alors que les nouvelles solutions de rafra\u00eechissement envisag\u00e9es par Trecobat repr\u00e9sentent un investissement initial d\u2019environ 1 500 \u20ac, sans surco\u00fbt de consommation ult\u00e9rieur.<\/p>\n
