Ventilation and cooling

Cross-ventilation via automatically controlled louver windows

The glass areas are equipped with exterior sun protection, which screens the residents from view at the same time. Because of night cooling and exterior sun protection it was not necessary to install an air condition system.

The thermal mass of the concrete walls functions as a cooling storage and are cooling the rooms throughout the day.

By the employment of triple glazed windows, highly effective insulation and a solar thermal system an energetically optimized building could be realized.
