Changes in the way of modern people live and work makes it more than 85% in the time to stay indoors, indoor thermal comfort environment can not only make people's mental and physical pleasure, but also improve work efficiency. Therefore, thermal comfort issues in the built environment of the subtropical region, further research is particularly important. Belong to the summer and warm winter in most parts of Guangxi region, Guangxi University, for example to study the regional campus building thermal comfort. In this paper, three different types of room (natural ventilation rooms, air-conditioned rooms and transitional space) as the research object, on the basis of field tests and questionnaires of Guangxi University campus building, established evaluation model of thermal comfort in summer and warm winter ; carried on the campus thermal comfort conditions in the building of the subtropical region, improve thermal comfort; simulation using intelligent algorithms optimized Guangxi conditioned buildings. Thermal comfort field testing, survey and analysis of the results of the data derived: the human thermal sensation is different in different buildings; Temperature effect on thermal comfort is the largest, followed by the air flow rate, and then humidity; the analyzed summer linear regression equation to predict the thermal sensation vote value of PMV and indoor operating temperature is PMV = 0.154top-3.2706, subtropical region thermal neutral temperature of 21.3 ° C, in the PMV evaluation mode 80% of the acceptable temperature range: 17.8 ℃ -24.8 ℃. In the actual design, a reasonable choice in the range of acceptable temperature air-conditioning design and operation temperature has little effect on human thermal sensation, but will directly affect the energy consumption of construction equipment. Application of intelligent algorithm summer indoor thermal environment of air-conditioned room, combinatorial optimization, and come in a different dress, different humidity and different activities to meet the conditions for thermal comfort, indoor temperature and wind speed optimized combination of changes in the range. Within such a range, the high value of the indoor temperature as far as possible to take appropriate to improve indoor humidity is between 40% -70% relative humidity to reduce air conditioning energy consumption. The results of the analysis of the transition space: air temperature greater impact, the value of the indicators of RWI Winds its great influence. We actually carried the parameter design of the transition space, within the temperature range of thermal comfort, an appropriate increase in humidity, the wind speed is increased to reduce the energy consumption.
