HVAC&R(Heating, Ventilation, Air Conditioning & Refrigeration) systems are the most energy consuming building services representing approximately half of the final energy use in the building sector. Despite their significant energy use, there is a lack of a consistent and homogeneous framework to efficiently guide research, mainly due to the complexity and variety of HVAC&R systems but also to insufficient rigour in their energy analysis. This research reviews energy consumptions of HVAC&R systems with the aim of establishing a common idea for the analysis of building energy efficiency. Our approach deals first with the concept of HVAC&R set that is composed of subsystems: HVAC system, heat/coolth generation system and water/air transport system. This study focuses on the equipment and equipment components used to generate heating and cooling. Secondly, the matrix combination evaluation is examined and total 960 HVAC&R sets can be implemented to commercial building. The method as a tool for energy analysis of HVAC&R sets was developed for a unique system energy map. The objectives of this study were to provide a physical understanding of the factors which contribute to energy use by HVAC&R system and provide a baseline estimate of energy use.
