Science and Education Publishing Sustainable Energy 2 1 2014 02 08 Combination of Wind Catcher and Chimney for More Energy Efficient Architectural Buildings 35 38 EN Mohammadjavad Mahdavinejad Sina Khazforoosh Department of Architecture, University of Tehran-Kish International Campus, Iran RSE2014217 10.12691/rse-2-1-7 2014 01 20 2014 02 01 2014 02 08 Energy, plays a crucial role in our everyday life. As energy supplies are limited, energy conservation is unquestionably one of the great importance to all of us. Although improving energy efficiency can be achieved in many ways, but energy saving in buildings plays one of the main roles in saving energy. Using natural ventilation systems can be effective to achieve this goal. This article tries to propose a pattern in which the combination of two common natural ventilation systems, Wind catcher and Chimney, will be use for optimum ventilation efficiency so that the energy efficiency will be increased.
