Short Description

The building consists of a single block of 98 meters in length by 16,40 of depth and with a height of 19,20 meters. Containing 88 homes distributed in five plants plus ground floor.

The construction occupies the 38,31 percent of the plot, the remaining area is devoted to green spaces.

All the houses have a double guidance East-West toward two green areas of different configuration. Along the facades there is a terrace of 1,5 meters wide that provides a space semi-abroad. These terraces are involved in screens of bamboo mounted in frames to be fold providing the necessary protection against the strong solar exhibition of East-West and giving security to the homes located in the ground floor which open entirely to the gardens.

Key Elements

Ventilation

The existing cross ventilation in this building provides air flow between different windows of the house located in two opposite facades. Therefore, they have a natural cooling in summer.

Solar Thermal

A heating system with centralized production, with individualization of consumption. Solar panels are used to produce hot water and backup of the heating and condensing boilers. The result is an energy saving of 40%, and a 67% less of CO2 emissions than conventional systems.

Certification

The building reaches a “C” level in the certification rate. These results are due largely to the efficiency of the systems of centralized heating and hot water. With an extra reduction of 8% of CO2 could have been rated “B”.

Main Results

The active elements of energy efficiency have reduced energy consumption by 40% and at the same time, have reduced CO2 emissions to 67% compared to conventional systems.

A microclimate has been created by taking advantage of abundant green spaces and the use of a climate suitable gardening with low maintenance costs.

Lessons learned

The facades have a great influence on building energy consumption and even influence the ecological footprint as the possibilities offered to repair or take advantage of waste materials that compose it at the end of the life of the building.

The use of abundant primary raw materials and low environmental impact.
