As is known, the energy performance of the buildings is directly related to both the energy efficiency of the mechanical and electrical-electronic systems in the building and the architectural design parameters of the building.
These parameters;
Location of the building
location relative to other buildings
Direction
Form etc.

Each of these parameters plays an important role in energy efficient building design and should be determined in relation to each other in such a way that they make optimum use of renewable energy resources in the building. The main goal of smart buildings is to ensure that buildings are energy efficient and the effect of these parameters on the design of smart buildings cannot be denied. Otherwise, the building will not go beyond being a classical building with automation and control of mechanical and electrical-electronic systems. The dimensioning of energy systems used in buildings is generally based on average meteorological data, and the world is not sensitive enough to benefit from renewable energy sources in the world. Thus, sufficient energy efficiency cannot be achieved even in smart buildings where advanced technological systems are used for energy efficiency.

As a result, the main goal of smart buildings is to increase energy efficiency in buildings and to provide customer comfort with the least possible energy consumption. In order to achieve this goal, the energy resources should be utilized at the optimum level and it is the awareness that the smart building does not consist only of automation systems as perceived in the world.
