Comparison of the world research trends and China 16 The top 9 most-frequently used keywords in papers from China The top 9 most-frequently used keywords in building Energy and environment China is in the first echelon of the building environment energy development, leading the research direction, for example: thermal comfort, energy saving, energy efficiency, IAQ, CFD. China research hotspots have heat exchanger, liquid desiccant, phase change material ， but we lack research on the thermal performance of building.
