ZERO ENERGY , SELF SUFFICIENT HOUSE, JOHANNESBURG A new design approach to help Africa become a better place. The new wavy zero energy house concept form was inspired by the wavy undulating lines of wood grains that was generated using computer algorithm via parametric design tools to drive wind and rain for ventilation to cool the house and harness rain water. The Main design concept depends on three axes of sustainability to achieve total self sufficieny 1.STORM WATER MANAGEMENT Rainfall amounts to 28 inches (700 millimeters) per year, and is concentrated in the warm period, from October to March, when the rains occur in the form of downpour or thunderstorm. Winter is rather a dry season, with rare and sporadic-rains. The main concept depends on harnessing the rain water via the undulating surface of the house that collects the rain water into the conical shapes then to underground reservoirs to be reused later. 2.PHOTO VOLTAIC CELLS ON ROOF The amount of sunshine in Johannesburg is very good throughout the year, as the sky is usually clear, even though the relatively least sunny season is the summer, because of showers and thunderstorms, which however do not last long and give way to the sun. For that reason and according to the preliminary calculations the house that is designed for a 5 members family needs about 10Kwatt in our contemporary life style and so the top roof was covered with photovoltaic cells of 100 watt/ m2 so the final area needed to cover and exceed a little bit the family's need is 120 m2 3.MANUFACTURING TECHNIQUE (Re-Use strategy) CLT is an engineered wood panel typically consisting of three, five, or seven layers of dimension reused lumber oriented at right angles to one another and then glued to form structural panels with exceptional strength, dimensional stability, and rigidity. Because of CLT’s structural properties and dimensional stability, this mass timber product is well suited to consecutive structural shear walls used in mid-rise construction. The wooden panels may be left exposed in the interior which provides additional aesthetic attributes. The panels are used as prefabricated building components which can speed up construction practices or allow for off-site construction. CLT is manufactured used the CNC digital fabrication approach; panel sizes vary acting as well as sun breakers or louvers that decrease the sun exposure into the inner space. While length is usually limited by transportation restrictions, longer panels can be manufactured. CLT panels are typically installed like plywood in terms of grain orientation. Structural panels are oriented with the grain of the outside layers parallel to the vertical loads of the application. Inner space applications have the grain of their exterior layers oriented parallel to the span direction. Openings within panels can be pre-cut in the factory to any dimension and shape, including openings for doors, windows, stairs, service channels and ducts. The resulting product is load bearing, stable and can act as a diaphragm or shearwall.
