Violet colored water (absorbs solar energy) as thermal mass, inside translucent polymer 3d printed roof structure - Polymer/plastic has good tensile properties. Windcatchers brings air to the water cellar (seen below)
20 degree overhang in 3D printed concrete, provide shade and screens from sand.
Billies paperplane flies upwards due to the air rising from the cool watercellar below, and up through air channels inside the polymer roof, holdeing the violet water for insulation.
The water (thermal mass) is heated up during the day, then pumped to internal polymer interior elements, seating, screen walls, railings, to release the heat, when it gets cold at night
The windcatchers brings a breeze down to the underground water cellar. Cold water mixes with air and pushes warm air up through columns with integrated airchannels.
