The paper presents results about a decreasing of a cooling demand in the selected office building where the night ventilation/pre-cooling of building construction is used. The energy saving is about 10 - 15% in comparison with operation of this Office building without using of night ventilation/pre-cooling of building constructions. Mechanical ventilation is used in this selected Office building and the airflow volume was calculated by using the technical standard STN EN 16798-1. These results we got by using energy simulation tool called DesignBUILDER. The computational model of a used Office building has clearly defined thermal technical and thermal optical properties of external building constructions. In the calculation are also included the internal activities such as occupancy in time or using office equipments in time. There is also used the artificial lighting with required light illuminance in the internal spaces of building. The using of a night ventilation/pre-cooling in the building brings the financial savings for owner of a building. It also brings energy savings and decreases the negative environmental impact (lower CO2 emissions). The lower cooling demand in the building also means the shorter operation time of cooling systems which cause the urban heat islands. Also in this direction we can wait the positive addition but not so big. There the green architecture can help and especially we need the complex approach to the building?s design in the world of sustainable cities.
