In the master's thesis we discuss the system of ice banks for storing cooling energy in Cankarjev dom. Such a system allows us to produce cold at night, when electricity is cheaper, and store it for use during the peak hours of cooling loads. The use of a system with ice banks compared to a conventional cooling system has the advantage of reducing system equipment such as pipelines, refrigeration unit (lower cooling capacity), savings due to cold production at lower electricity prices, relieving electricity distribution during peak cooling loads, etc. In the TRNBuild program, the construction of Cankarjev dom was made and it consists of 40 zones. In the Trnsys program, a simulation of the cooling system before upgrading to ice banks was performed, thus defining the energy need for air conditioning of the Cankarjev dom. A simulation of the system with ice banks is then performed to calculate the proportion of energy provided by the ice banks. Validation of module 843 was done to simulate the ice bank model in the Trnsys program. A simulation of the system upgrade with ice banks with photovoltaic panels was also performed. An economic analysis of the investment in a photovoltaic power plant with a nominal power of 51.6 kW has been made.
