Today, although construction projects are tried to be based on green and smart discourses, it is seen that the targeted benefit is not achieved mostly due to commercial concerns. In projects without financial concerns; Due to the insufficient engineering analysis and lack of lifetime cost approaches, buildings that have been launched as green and / or energy efficient often do not go beyond being just technological elements. Having technological elements in a building is not enough to make it efficient most of the time.

The lifetime operating costs of a building are much higher than the first investment budget of the building. Especially for organizations that will undertake the construction and operation of a building, lifetime cost analysis of the buildings is much more important than the initial investment costs of the building. Accordingly, building energy modeling is vital in terms of both analyzing buildings in the investment process and analyzing the effects of investments on operating costs.

Building energy modeling plays a vital role in determining the capacities correctly in the investments of air-conditioning systems and making the capacity predictions of a possible cogene-trigen investments healthier.

With the modeling created over 8760 hours, the effects of all kinds of system investments on building operating costs are analyzed in detail.
