12 Standard Floor Plan Facades East (114º) and West (287º): sun and natural illumination in all units in the morning and in the afternoon

13 Standard Floor Plan Dorms. in west facade for afternoon heating Heat accumulation for night-used space Soundproofing between units Solid 15cm concrete slabs North face semi-dettached Big openings for south facade. Shading protection from the balcony. Big openings (1,20m kitchen 1,40m others) stimulate the natural ventilation through chimney effect Doors, windows, columns and beams indicate several possibilities of space layout

14 Standard Floor Plan Heat gains reduction during winter and heat loss reduction during the summer Shading and ninght shutter Cross Natural Passive Ventilation High absortance Dark brown bricks bring high absortance for heat accumulation 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 Double glazing (heat loss reduction during the winter) Windows with two layers of glass and internal air layer.
