The vigorous growth of global economy expanded by 3.7% in 2018 and increasing demand of heating and cooling in buildings has increased the energy consumption throughout the world. Worldwide energy consumption rate has grown to about twice the rate of growth since 2010 to 2.3% in 2018. The share of energy use in buildings is increasing due to increasing needs of HVAC. In India, 32% of the total electricity consumption is in residential and commercial spaces which are rapidly increasing with urbanization.The conventional practices being followed have an option of having efficient alternative of passive means of heating and cooling of the buildings. Use of solar chimney involves the solar energy utilization in the air velocity. Literature has been examined on the passive ventilation technologies and presented in this study. Several studies have been performed on the design parameters and the thermal performance of the solar chimney globally. Experimental evaluation and numerical simulations on application of solar chimney in ventilation show the effectiveness of the passive ventilation. Some studies show the effect of design parameters on the air flow rate.Apart from the mathematical and experimental studies, Computational Fluid Dynamics (CFD) studies were also performed by several researchers for the analysis of solar chimney performance. Literature shows that the CFD analysis has been performed to validate the experimental and mathematical results. The review concludes that there is a great scope of full scale experimental analysis of the solar chimney system for the effective ventilation and studies for the Indian context will contribute in the efficient ventilation system design.
