The paper describes the dynamic model of maintenance and investments of a building structure and HVAC systems. The aim of the research is finding the time dependent curve for energy consumption and also the cash flow that depends on the investments to energy saving arrangements and operations. The solution is based on the system dynamics method. The method makes possible to interconnect technical and economic parts of the problem. The main parameter in the model is the energy consumption in the building per floor square meter and year. This parameter is influenced by a deterioration of the building structure and the components of the active elements. The investments realized with the aim to decrease the energy consumption is another influence. The example of the computer simulation of the building parameters during the life cycle is presented in the paper.
