Design of Passive Cooling and Heating System

Project Overview

The last two decades have witnessed a rigorous energy crisis in developing countries, mainly during the summer season, principally due to the cooling requirements of buildings. The consumption of energy in buildings is very high and is predicted to be increased further owing to improved living standards and an increase in the world's population. The excessive use of air conditioning has been clearly increasing in the market over the past few years and significantly contributes to the increase of supreme energy consumption.
Regarding to the Global Watch Institute, buildings consume about 40% of the world's energy production. Energy use in buildings also accounts for 33% of all annual carbon dioxide emissions, contributing significantly to climate changes resulting from the accumulation of thermal combustion gas. Take for example, the case of India, the construction sector accounts for about 33% of electricity consumption, and the commercial sector accounts for 8% and 25%, respectively.

Project Objectives

Passive cooling and heating techniques can reduce the peak cooling and heating load in buildings, thus reducing the size of the air conditioning equipment and the period for which it is generally required. Therefore, in this project, passive cooling, heating techniques and energy efficiency measures will be addressed. Moreover, different passive cooling and heating techniques and their role will be discussed in providing thermal comfort and its significance in energy conservation.
