Abstract：

Analyses the status of energy source development and utilization from the aspects of energy reserves and energy utilization in China. Aiming at the HVAC profession, puts forward the countermeasures and methods of increasing the utilization of new energy, reducing energy consumption of HVAC systems with passive priority and improving energy efficiency with active optimization. Urges that the HVAC researchers should pay more attention to five issues, i.e. the design concept, device energy efficiency and energy efficiency standards, system energy efficiency and monitoring control, life cycle costs and design and construction.
