WRITE IT UP (p.68)

Ladies and gentlemen....
During winter, ouside air is captured by warm glass roof panels. Then,
warm air is forced down into a water tank by an air handling unit.
Next, the water in the tank is heated and greater quantities of warm water
air are released. The hot air is then sent down a duct to the crawlspace in
under-floor area. After that, warm water rises through floor registers to the
living space. Some of the heated air is absorbed by concrete slabs . It is
released at night. This process is reversed during summer.
