The purpose of the work is to determine factors internal and external affecting the cooling energy demand of the building. During the research, the impact of weather conditions and the level of hotel occupancy on cooling energy, which is necessary to obtain indoor comfort conditions, was analyzed. The subject of research is energy consumption in the Turówka hotel located in Wieliczka (Southern Poland). In the article, the designer of neural networks was used in the Statistica statistical package. To design the network, a widely-used multilayer perceptron model with an algorithm with backward error propagation was used. Based on the collected input and output data, various MLP networks were tested to determine the relationship most accurately reflecting actual energy consumption. Based on the results obtained, factors that significantly affect the consumption of thermal energy in the building were determined and a predictive energy demand model for the analyzed object was presented. The result of the work is a forecast of cooling energy demand, which is particularly most important in a hotel facility. The prepared predictive model will enable proper energy management in the facility, which will lead to reduced consumption and thus costs related to facility operation.
