Dr. Azher Muhsen, Head of Air Conditioning & Refrigeration Engineering Techniques Dept., has accomplished new scientific success with the collaboration of global universities in the effect of CO2 emissions on sustainable buildings. The research has included the effect of CO2 emissions on energy efficiency studies in buildings. According to several scientific papers, the construction sector is considered to be the main source of CO2 emissions which affect the Ozone Sphere. Therefore, this study has been conducted to show that sustainable energy is a perfect solution for CO2 emissions. The study provides essential and useful measurements for ECO2 effects. In addition, CO2 emissions can be controlled through carbonite substances in energy. Finally, the main benefits are less energy consumption, high performance as well as fast and sustainable processing
