electric power consumed by the cooling sources were measured in two air-conditioned office buildings. The measurement results were used to calculate the cooling energy generated during the measurement period and the operational Energy Efficiency Ratio EERo of the chillers. Electric energy consumed in the measuring period by the auxiliary equipment of the cooling system, i.e.: coolant pumps and fan coil fans, was estimated. The possibility of significant reduction of the energy consumption for air

weather station. The results of the study indicate the necessity to use cooling in the museum premises. Presented analysis of the heat loads, which can occur in the exhibition rooms, can be helpful in making the decision about the installation of air conditioning systems in the museum, especially when thermal renovation of the building is planned. Such system can guarantee proper protection of the exhibits as well as thermal comfort for visitors.

INTRODUCTION
Every day people spend a lot of time in public transport, for example buses, trams, trains or subways. To make their journey comfortable, appropriate thermal conditions must be provided by HVAC (Heating, Ventilation, Air Conditioning) systems. Thermal comfort is achieved when passengers perceive the air temperature, humidity, air movement, and
