Sustainable technology for energy and environmental benign building design

A sustainable technology has been proposed to satisfy the total energy and gas demand for a building which can be produced by the building itself without any outsource connection. To satisfy the energy demand of 100% of a building some portion of its exterior curtain wall skin can be used as the black body acting PV (photovoltaic) panel to capture solar energy and convert it into electricity energy. The domestic waste including humane feces is proposed to be implemented into transforming process in site where sludge shall be collected into a closed anaerobic detention tank at cellar to introduce into a bioreactor; allowing to produce biogas (CH4) by Methenogenesis, then store, and utilize it for cooking and HAVC equipment. Then, the separated waste water to be collected and treated in site by applying all primary, secondary, and tertiary process and the treated water be used for gardening, and landscaping. Combined all these technologies simply would be an innovative field in sustainable science where a building can itself produce electricity and gas without any outsource connection to meet its total energy and gas demand which is benign to the environment.
