Evaluation of energy saving investments in buildings as a system of interdependent projects

During a design stage building designers have to do many decisions that will influence an energy consumption in a designed building. Investments to a building structure and HVAC system are a basis for a low consumption of an energy. The decision making process is considered as the system of investment decisions where one certain decision is a project. The program has been developed for the selection of solutions for defined restrictions. One example is presented for the evaluation of different possible combinations of energy saving projects in a real building.
