In summer, louvered openings in the lower quadrants of the glass structure bring in cool air, while warm air is expelled through roof vents. This mild climate allows the occupants to gather in the atrium, reducing the need for larger indoor spaces. Fresh air pulled through concrete-lined tunnels 10 feet below ground is naturally heated or cooled, depending on the season, before it is released into the glass envelope. There is no air-conditioning. Instead, a computer system monitors internal and external temperatures and adjusts openings in the envelope accordingly.
Rainwater is collected on the roof, filtered, and stored.
It is used to clean the roof, flush the toilets, and water the lawns. A photovoltaic array on the roof and the south and west facades provides plenty of electrical power. Surplus power is stored and used at night and during periods of low light. The rest of the surplus energy is channeled into the public power supply. Trees shade the facade in summer.
