Investigation of Natural Heating of buildings by Solar Chimney at Various Solar Heating Cases

Abstract

The use of traditional energy becomes more costly and causes pollution for the environment. Nowadays, the whole world thinking about using renewable energy instead of traditional energy. In this work an experimental study has been conducted to study the use of solar energy in heating the buildings by the aid of a solar chimney. The solar chimney was installed with and without using of storing material. The storage material is used in order to store energy for heating purposes during sun shining and after sun set. The study indicates that the temperature inside buildings could be kept higher than the ambient air temperature during the day as well as during the night for many hours. This leads to decrease the demand of classical energy and consequently decreases the cost. The results indicated a decrease in monthly costs of energy use by about 26.73$ per cubic meter in the case of using chimney without storing material and about 60.11$ per cubic meter in the case of use solar chimney with storing materials.
