ABSTRACT

Passive solar architecture functions are at the core of a triad of efforts to make human activity more a part of our planet and provide resources for future generations. Air-flow is critical, so an ACH of 30 is desired. Landscape elements can also be designed to enhance ventilation at the lower levels. A green roof is a roof that is partially or completely covered with vegetation and soil. Conceptual and schematic designs resulting in a natural ventilation plan can be developed. The brightness distribution is typically about ten times greater near the sun than at the darkest part of the sky. Many of the system designs have still been quite primitive, but we can expect that competition in the market will deliver systems with higher solar fractions. Rainwater harvesting is a method of capturing high quality water. Biological waste treatment systems which utilize aquatic systems and greenhouses or ponds can successfully treat blackwater to a drinking water quality.
