Natural Residential Climate Regulation Holistic architectural design takes all systems into consideration and sees a house as an ecosystem within an ecosystem. Green New World’s homes are designed as self-sufficient structures with integrated energy, water and sewage processing systems. Careful design considerations such as orientation of building, windows, solar gain, insulation and thermal mass can be integrated to create a comfortable climate without any further cooling or heating requirements. In some climatic scenarios an additional cooling or heating system may be required. Natural cooling systems such as wind capture, thermal uplift, evaporation chambers and solar cooling can maintain a comfortable climate inside. Heating systems can use several options such as solar, aerobic heating reactors, geothermal, biogas or wood burning stoves and ovens.
