Energy-Consumption Reduction Through a New Integration of the Passive Solar Systems in Building

Recently, there has been a growing interest in the development of innovative research of solar passive systems and their combination with other strategies for raising their efficiency. The major weakness of the sunspace is the uselessness of it in the summer season, moreover, the main defect of the solar chimney in the building is its low usage in the cold season of the year. In this way with the combination of two systems (SS) can reduce the annual energy consumption of the buildings. To calculate the amount of thermal performance through the new system, First, a room with a southern window in three configurations was designed: usual room, with a sunspace along with integration between sunspace and solar chimney(SS). Afterward, the impact of these passive solar systems on energy consumption was assessed. The simulation was performed through the Energyplus software. Based on the results, applying the SS system in buildings can magnify the amount of heat obtained. Moreover, natural night ventilation over the SS can reduce the cooling load during hot seasons. The results additionally indicate that the highest energy-saving for heating and cooling observed in January and July respectively.
