This paper discusses issues related to cooling load and energy consumption for air conditioning systems and presents the results of calculations conducted for six different climate localizations: three in Poland (Bialystok, Warsaw, Wroclaw) and three in Spain (Burgos, Madrid, Cordoba). Analysis was conducted for a same lecture hall design for 100 users locates in the different cities. During cooling load calculations, we focused on gains from diverse type of heat sources: electrical devices, air infiltration, heat transfer trough envelope and occupants. Calculations were made for a comfort temperature that was set at 22°C in Poland and 24°C in Spain following previous studies . The highest contributions to cooling load correspond to occupancy and solar gains which depends mainly on outdoor conditions. In Poland, cooling load was found similar for different locations, while in Spain, they are big differences between cities located in North and South of this country by effect of different outdoor conditions. The work also compares cost of air condition annual energy consumption costs for the air conditioning system. Highest cost for cooling was found in Spain (Cordoba) with value (2629 €) almost 378% higher than average Polish cost.
