Ventilation and cooling will be achieved using cooling tubes buried from an air entry well in the west yard and running in to various strategic parts of the building. These tubes will provide access to cooler air from deeper in the earth. EXHIBITS N & O
The warmer outside air hits the cool tubes and causes condensation on the tubes thus extracting moisture out of the air as it moves through the tubes.
This movement of air is intensified by using a convection duct placed in the path of the summer sun. The duct has a flat black surface that is glazed over. The sun hits it all the way along the eighty foot length of the steel strucure and creates extreme heat. This duct is linked down to the greenhouse and this creates an intense pull of air through the green house. This pulls air through the cool tubes and through the living spaces much stronger for more of a venting and cooling effect. EXHIBIT Q
The fact that the summer sun is missing the entire building leaving it is entirely in the shade and partially under ground goes a long way toward cooler temperatures in the summer. The convection cooling will take it the rest of the way.
The building walls are to be made of 2'-0" thick mass insulated on the outside. This will trap temperature in the mass. The fact that intense heat only enters the building in the winter and it is in the shade in the summer leaves the insulated mass to stabilize at something cooler than summer and warmer than winter. This is expected to be very close to the comfort zone for humans based on past perforance of this type of building in a multitude of climates. EXHIBITS N & O
The reflection mirror relfects only the winter sun down into the building for serious heat gain for a big part of each winter day. EXHIBIT R. This heat will be stored in the insulated mass walls of the building. This mass acts as a heat sink to absorb this heat during the day and giving it back at night as heat travels to the cooler place (physics). The volume of mass of will take over one year to finally stabilize absorbing summer and solar heat and leaking it out in the winter. The building should stay very close to the cofort zone of 70 degrees F in all times of the year.
As a comfort precaution, the hot water system has described a back up warm floor system.
It should also be noted that the living spaces are all one buffer zone (greenhouse spaces) away from the outside thus making them removed from outside temperatures and subject only to the temperatures stored in the thermal mass walls.
