Abstract: This article introduces two system models to simulate the energy performance of the temperature and humidity independent control air-conditioning system (THICS) and the conventional airconditioning system (CAS). The energy performance comparison includes three parts of cooling resource, transportation system and terminal devices. A typical office building with these two different systems is numerically analyzed. Beijing and Guangzhou, two major cities in China, are chosen, which lay in temperate zone and tropical zone respectively. In Beijing office building, the Energy Efficient Ratio (EER) of THICS is 4.5, while which of CAS is 3.6. In Guangzhou office building, the EER of THICS is 4.5, while which of CAS is 3.4.The energy efficiency of THICS is higher than that of CAS and THICS can save 20%~30% energy consumption compared with the CAS. In detail, cooling resource accounts for the biggest part of the energy-saved. KEY WORDS: THICS, air-conditioning, transportation, energy performance
