A water pipe has been laid underneath the large floor area. The flooring is heated with hot water in the winter and cooled with unheated water in the summer. Fresh air also constantly flows through the building via the ventilation openings in the base and roof of the glass shell. This air is cooled or heated via the floor, depending on the season. This principle originates from the idea of a traditional Andalusian patio (planted courtyard) in southern Spain.
The façade consists of triple glazing with solar control glass and several printed layers for heat protection. Behind the façade, the recirculating airflow provides ventilation. The curtains also have an innovative metallic coating on the outside, which reflects sunlight outwards and keeps the interior cool.
Thus a building 105 metres long, 25 metres wide, and 12 metres high has been created within a construction period of just under two and a half years. A total of 571 triple-glazed panes were installed in the façade, providing thermal insulation, sun protection, bird protection, and security for the art on display.
