In an international design competition, our submission for a bioclimatic school in Crete won third place. Our proposal responds to the competition’s directive that all educational units — from kindergarten to grade twelve — interact in a holistic manner, while at the same time maintaining the ability to operate independently.
Two main factors influenced our sustainable design strategies and established the general orientation and massing of this bioclimatic school: consistency of wind direction, as well as Crete’s high number of annual sun hours (approximately 2700). Cross ventilation, southern exposure, and thermal mass are carefully orchestrated in our design.
Organized as three different courtyard buildings, the school is defined by its solid exterior walls. Carved from this white mass, vertical wind corridors are created to allow for cross ventilation and passive cooling to the complex under the hot Mediterranean sun. Lining the interior of these courtyards, a cloister shaded by olive-wood fins further reduces solar heat gain. Site ecosystems have also been thoroughly considered for the purposes of biodiversity, water retention and purification, and heat dissipation, among other objectives. Taking advantage of the natural topography of the site, a water retention strategy is employed to collect rainwater at the bottom of the slope for irrigation.
