An example of a central air-conditioning project of a rebuilt department store is described in this paper. The design of air system, water system, layout and operations for the air conditioning system is presented in this paper. The system is different form ordinary ones because the floor height is lower; so many special considerations must be taken during the design. In addition, the low cost and easy maintenance place an important role in the design. The operational result of the design is promising and it can be referenced by other designers.

Allowing users to track the household metering energy consumed by their central air conditioning system is an extremely effective strategy for saving energy in commercial buildings. This paper presents several methods of measuring the energy consumed by a central air conditioning system, such as using time-based and energy-based models. The accuracy and reliability of these models are also compared with each other. Finally, a novel energy metering method, the improved electricity-based model, for a variable refrigerant volume (VRV) air conditioning system in commercial buildings is proposed based on a case study of the Li Wenzheng building at Southeast University.
