Buildings consume energy specifically for heating

Buildings consume energy specifically for heating, ventilating and air conditioning (HVAC) systems. The hot countries such as the Middle East regions and south of Algeria use large parts of energy for air conditioning, despite their significant solar energy potential. The household electricity bill is very high in summer because of air conditioning uses where expenses are not within reach of every budget. The idea is to promote natural ventilation in dwellings by free convection. The passive cooling technique can be used to reduce mechanical air conditioning requirements in areas where cooling is a dominant problem.
Passive ventilation saves energy and cuts down on carbon monoxide emissions. It is inexpensive, energy-efficient and low-cost maintenance. Fossil fuels are known by their nature polluting the atmosphere. Nowadays, the current trends are oriented towards new energy resources which are friendly energy environment and low energy consumption.
