RESULT
1 _ White prism with shared central void (patio)
2 _ Hyper modular plan based on a 3x90 grid
3 _ Glazed / opaque ration down to 21%
4 _ Standard concrete structure with prefabricated beams, columns and slabs
5 _ Standard prefabricated frame facade, only 3 modules (90cm glazed, 90cm opaque, 90 cm mixed glazed + opaque)
6 _ Thermal concept based before all else on reduction of heat gain or loss, ...and completed by passive technology
7 _ Certified, recyclable, native sources as much as possible
8 _ Reduction of suspended ceilings, inner finish of prefabricated facade frames included,reduction of plaster rendering (painting concrete)...
RE-DETERMINED OPTIONS
Compact volume _
Flexible space _
Optimal glazed / opaque ratio _
Simple prefabricated construction principles _
Highly insulated and air-tight prefab.skin _
Low-tech passive technology _
Special attention to material life-cycle _

standard maison passive
Comment l’atteindre?
Minimiser les déperditions– compacité
– isolation de l’enveloppe (K 14)– étanchéité à l’air (n50 < 0.6 h-1)– ventilation double flux + récupération de chaleur
Maximiser les gains de chaleur
– gains internes
– gains solaires

stratégie de froid
Minimiser les besoins de froid– protections solaires extérieures: lamelles orientables– éclairage: luminaires à haut rendement (< 2 W/m².100lux)– régulation: compensation lumière du jour, détection de
présence
Refroidissement passif– puits canadien– ventilation nocturne
