Performance Evaluation of the Passive Energy System (Trombe Wall and Conservatory) in Cold Climate for Energy Saving

In the recent century, due to the reduced energy consumption and excessive use of non-renewable resources in the building sector, passive solar heating is one of the architectural design strategies for efficient energy use. Trombe wall and Greenhouse are the most important passive systems. This project, by conducting field-laboratory studies, evaluated the energy consumption in five different models from the combination of a Trombe wall a the Greenhouse with a chamber in the first and second six months of the year in the cold climate of Ardabil city. In this research, the idea is not to consume, but to use green energy and minimize energy consumption through the absorption of renewable energy in the building, in this regard; architectural design can play a very important role. This research is semiexperimental and uses a simulation research method. In order to achieve the goals of the project, the Design Builder software has been used to analyze the conditions. According to the studies, it is realized that with the installation of the Trombe wall with window and adding shading to the southern side of the building, the average temperature will be 20/67°C in the winter and 22/84°C in summer, and the comforttemperature will be 18-22°C in all months of the year. We can also receive a enough daylight during the day and we can achieve environmental sustainability and reduce costs apart from achieving comfort in the environment, and reducing non-renewable energies.
