Susar (Sustainable Architecture & Agriculture) is a collaboration of designers and constructors of sustainable residences. The container houses which are to be placed in Africa can be delivered prefabricated. This container house is built according to the most modern insights. It is completely energy neutral, and can even generate energy for the community. All these designs fall into the category of sustainable living, and were created with state-of-the-art technology. In this case the wind load on the houses have an impact on the natural ventilation system.
CFD Pressure simulations
The container houses are to be placed in Africa and must be able to withstand the prevailing weather conditions. The company wanted to know how the air flow would pass around the house. This was to optimise the natural ventilation in the house, which could be complemented by ventilation running on solar energy. Physixfactor determined the wind load and pressures on the house and their effects on the ventilation system.
CFD analysis of ventilation system
A Computational Fluid Dynamics (CFD) analysis was designed for several container houses. This provided insight into the flow profile around the houses and the air flow of the ventilation in the houses. It yielded energy savings because it diminishes the use of fans for the ventilation system. The stress of wind was simulated to determine the rigidity and stability of the residences in strong wind conditions, given the meteorological circumstances in which the residences will be placed.
The ventilation could be optimised this way for all wind directions and strengths. The functioning of the ventilation has become more reliable and satisfies the latest insights into the area of energy-efficient and sustainable housing.
