In this paper, five cases with various scales of housing complex and operating modes of combined heating and power (CHP) system were studied. Computer software, HEATMAP was used to simulate the operation of these CHP systems. The results can be summarized as follows: 1) For a practical project, each case has optimal CHP equipment's capacity considering various evaluation indexes. 2) In a 1-hectare housing complex development site, introducing CHP system with track electricity operating mode can achieve a maximum of 51.4% overall energy utilization efficiency, 5.13% energy saving ratio and 24.41 % CO_2 reduction ratio. However, users will spend more than 8.01 years to return the investment of the CHP system. 3) Optimizing on operating mode can achieve certain degree of economical benefit; however, the improvement is limited. To achieve better operating eftect of CHP system, it is necessary for the users to expand the volume and scale of housing complex 4) Enlarging the volume or scale of housing complex can achieve better energy, environmental and economic effect. Doubling the volume of housing complex can cause overall energy utilization efficiency to rise about 3.3% and CO_2 reduction ratio to increase by 8.53%, and reduce the payback year by 3.67 years. Doubling the scale of housing complex can increase approximately 6% overall energy utilization efficiency and 12.37% CO_2 reduction ratio, and make the payback year 2.15 years shorter.
