Summary

Energy management of heating, ventilating and air-conditioning (HVAC) systems is the biggest single energy consumer among all building services, installations and electrical appliances. HVAC system should provide a dynamic response to the non-linear change of influential parameters on a seasonal or even daily basis and meet the high demands of thermal comfort and air quality during working hours. There are many participants involved during the building life cycle including owners, designers, constructor, managers, operators, and users. As the building complexity grows, communication and understanding among them usually decreasing. Numerous evidence suggests that many buildings do not perform as intended by their designers and their actual energy performance is often significantly higher than theoretical. The reasons for this include faulty construction, malfunctioning equipment, incorrectly configured control systems, system ageing, purpose or demand changing and inappropriate operating procedures. Therefore, it is necessary to identify opportunities for building performance improvement and to implement effective system upgrades. Building management system (BMS) provides much data about building energy effectiveness that can be used by operators and managers in comprehending what really happens in a building. If the system is properly designed, professionally installed and regularly maintained, increasing its energy efficiency could be achieved through optimization of control strategy. Efficient HVAC control and tuning control loops is often the most cost effective option to improve the energy efficiency of a building. Defining such a complex control strategy requires understanding of the heat transfer processes, principles of operation of mechanical, as well as control segment of HVAC system. Besides, significant level of cooperation between different scientific disciplines and is necessary to get full understanding how well, or how poorly, building
and its systems are functioning. In order to identify potential for energy savings in building and to redefine control scenarios, HVAC system commissioning should be carried out. This paper presents a possible approach of solving described problem
through practical example
