Standard Floor Plan
•Facades East (114º) and West (287º): sun and natural illumination in all units in the morning and in the afternoon
North face semi-dettached
Big openings (1,20m kitchen| 1,40m others)
stimulate the natural ventilation through chimney
effect
Big openings for south facade. Shading
protection from the balcony.
Doors, windows, columns and beams indicate several possibilities of space layout
Standard Floor Plan
Soundproofing between unitsSolid 15cm concrete slabs
Dorms. in west facade for afternoon heatingHeat accumulation for night-used space
Thermal Inertia
Heavy and solid materials
(Ceramic masonry brick)
Passive Ventilation, Natural
Illumination and Higher Solar Heat
Gain during Winter
Big and tall opening windows
Heat gains reduction during winter and heat loss reduction during the summer
Shading and ninght shutterStandard Floor PlanCross Natural Passive Ventilation
Double glazing (heat loss reduction during the winter)
Windows with two layers of glass and internal air
layer.
High absortance
Dark brown bricks bring high
absortance for heat
accumulation
