All structural walls and interior divisions are made with TAPIALBLOCK ® 10/20/10 precast blocks. The building breaks down into three aggregate units of three to four homes per landing. All types have double orientation and the interior patios are covered by a solar atrium.
Structure: The structure is made with the Tapialblock® System 10/20/10, joined with the Fetdeterra base lime mortar
The thickness of the structural walls is 20 cm placed according to the Flemish rigging. The locking walls are 20 cm in case of separation between dwellings, thus guaranteeing, through their mass, the requirements of CTE_HR, and 10 cm in case of separation of interior spaces within the same dwelling, both made with Tapialblock ®.
Facades: The exterior facades are formed by the bearing walls of the Tapialblock ® System, viewed from the inside and covered with exterior insulation for the facade with natural cork and natural lime mortar finish
Reduced heating demand: Heat collection is increased by direct solar radiation from the collector galleries. The air renewal system will be through the collector atriums that use the air preheated by the greenhouse effect, increasing the internal temperature by convection. Both the external insulation and the inertia of the load-bearing walls made with the TAPIALBLOCK ® system allow, by conduction, to conserve the comfort temperature.
Reduced demand for refrigeration: The houses have cross ventilation in the direction of the prevailing winds and a constant airflow generated by the solar chimney of the patios. Inertia allows cooling the earth’s walls at night. The use of materials with good hygrothermal behavior, such as compacted earth, helps to regulate the humidity in the home, improving the thermal sensation.
Energy impact of materials: Materials with low incorporated energy are used, which can be reduced, recycled and reused in order to increase the closing of cycles of the materials. They are materials, like earth, that contribute to maximum hygrothermal comfort. Global CO emissions are reduced by 58%.
