The Use of Natural Energies Coincided With Appropriate Design for Cooling, Ventilating and Exhausting Undesired Gases from Factory Buildings

Abstract

Due to the arousal of energy crisis in the world, it is wise to use simple but effective building techniques that coincided with chosen physical characteristics of building materials to minimize energy consumption, depending upon two main concepts as follows: A-Passive solar energy coincided with the 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 the 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 the chimney effect by using circumferential cavity walls by using four types of wall design and building materials as follows:1-Normal solid wall2-Metal panels3-Mass Trombe wall4-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 "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 generating 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.
