Abstract
Due to the arousal of energy crisis in the world, it is wise to use simple but effective building techniques coincided with chosen physical characteristics of building materials to minimize energy consumption, depending upon two main concepts as follows: A- Passive solar energy coincided by chimney effect. B- Prevailing wind. Literature review showed the use of "Wind Catchers" especially in the Middle-East Zone in order to bring cool air or to get rid of hot air or both, with assistance of the prevailing wind. The aim of the research is to develop the use of wind catchers in buildings to get rid of hot air or smoke through chimney effect by using circumferential cavity walls by using four types of wall design and building materials as follows: 1- Normal solid wall 2- Metal panels 3- Mass Trombe wall 4- Water Trombe wall These circumferential cavity walls work as heat transmission barriers for inner spaces in one hand, and to exhaust the fume and naturally ventilate the inner spaces in the other hand. This means using of "Non Paid and Non Pollutant Energy" in all hot or cold seasons. In winter (in cold zones) we may use extra design manipulation like using prevailing wind forces mechanically or to generate electrical energy by special propellers; stored in batteries. The paper suggests making use of the chimney effect phenomena through the gaps of the cavity walls in factories by using free natural energies which depend upon reliable scientific facts in addition to its suitability for structural and aesthetical treatments which are applicable architecturally.
