Heating, ventilation and air conditioning (HVAC) system consumes a large proportion of energy in buildings. With the continuous development of energy-saving and green building, the professional quality of people who is in charge of the operation of HVAC system is one of the critical factors, which cannot be ignored. In order to meet the requirement of the times, as well as to cultivate talents with good quality for operation of public utilities, substantive work has been carried out at Nanjing Tech University, which includes the concept of education, cultivation objective, construction of curriculum group, rebuilding of teaching system, establishment of practical teaching base, mode of practical teaching, and engineering training of teachers. It has obtained both acknowledgement of students and support from industry. By combination of the idea of engineering education and the practical project, intellectual support can be provided for sustainable operation of building which will be real "green" and "energy efficient".
