\n

Con\u00e7u en 1926 par l\u2019architecte J. Caluwaers, le \u00ab Relais \u00bb est l\u2019un des b\u00e2timents de logements de la Cit\u00e9-jardin \u00ab Volta \u00bb \u00e0 Ixelles. Construction remarquable avec des fa\u00e7ades typiques en brique, il constitue un patrimoine important pour la commune.<\/p>\n

Programme et fonctionnalit\u00e9<\/h4>\n

Le programme comprend 53 logements en respectant le panache demand\u00e9 par le Ma\u00eetre d\u2019Ouvrage au stade du concours : 6 studios, 28 appartements 1 chambre (dont 2 PMR), 15 appartements 2 chambres et 7 appartements 3 chambres. L\u2019agencement des appartements respecte au maximum la structure int\u00e9rieure (murs mitoyens et de refends) des b\u00e2timents.<\/p>\n

Performance \u00e9nerg\u00e9tique<\/h4>\n

Le b\u00e2timent subit une r\u00e9novation lourde au sens de la r\u00e8glementation PEB. Les fa\u00e7ades existantes pr\u00e9sentant des caract\u00e9ristiques int\u00e9ressantes au niveau du patrimoine, les logements seront isol\u00e9s par l\u2019int\u00e9rieur tout en respectant les exigences PEB (U<0.24W\/m\u00b2K).
\nLa r\u00e9novation suit \u00e9galement une approche pragmatique mais ambitieuse : elle vise des besoins nets en \u00e9nergie de chauffage (BNC) de moins de 18 kWh\/m\u00b2.an (soit un niveau \u00ab passif \u00bb pour une r\u00e9novation) pour les logements favorables et un niveau global moyen tr\u00e8s basse \u00e9nergie (BNC < 30 kWh\/m\u00b2.an) pour l\u2019ensemble du projet.<\/p>\n

Techniques sp\u00e9ciales<\/h4>\n

Pour des questions de maintenance, une installation centralis\u00e9e assurant le chauffage et la production d\u2019eau chaude sanitaire est pr\u00e9vue en sous-sol (chaudi\u00e8re gaz condensation, ballon de stockage d\u2019eau chaude et boucle sanitaire performante en termes d\u2019isolation).
\nAu niveau de la ventilation, chaque logement disposera d\u2019un syst\u00e8me C+ individualis\u00e9. Cette approche pr\u00e9sente un avantage en termes de maintenance (entretien filtre), de r\u00e9gulation et d\u2019efficacit\u00e9 \u00e9nerg\u00e9tique.<\/p>\n
