Today the world is facing an energy crisis. Limitation of energy resources and environmental destruction caused by excessive consumption of energy resources are two major problems that today's society is facing. Paying attention to the external space around the building and its ability to influence the energy efficiency is a problem that has been investigated in this research. Some experts refer to open space as "space" and place it in front of "mass". Open spaces act as micro-climate regulators and lead to climate moderation through solutions such as passive cooling, shading, providing daylight and natural ventilation. Correlation between the typological characteristics of open spaces, for example, their architectural design, the surface of the areas exposed to environmental factors, and the amount of lighting and their orientation has been the subject of many studies to investigate the thermal performance of these spaces. In the present research, the effect of the characteristics of the mass-space system on energy consumption has been evaluated in the literature, and in the proposed design, using energy simulation in the Design Builder software, the placement of open space in the mass for medium-scale buildings short order with general performance has been done with regard to reducing energy consumption. According to the required infrastructure, this simulation examined 6 samples with different placement of open space in the building mass, and each sample was evaluated in 5 directions of -30, -15, 0, 15 and 30 degrees. According to the obtained results, two-story buildings consume less energy than three-story buildings. In addition, using the surface-to-volume ratio parameter, it was determined that the amount of energy consumption has a direct relationship with the surface-to-volume ratio, and the smaller this ratio, the lower the energy consumption. Heating energy consumption in all samples increases with rotation of 15 and 30 degrees towards east and west. But the cooling energy decreases with 15 degrees of rotation towards east and west. Since by reducing the consumption of cooling energy, electricity consumption can be saved, so this solution can be used. With a rotation of 30 degrees in relation to east and west, the total energy consumption increases in all samples.
