Stratum ventilation - a low-carbon way to thermal comfort and indoor air quality

The first decade of research into stratum ventilation is reviewed in the current manuscript. The background which midwifed the concept of stratum ventilation is introduced. Stratum ventilation is found to provide thermal comfort in warm conditions. Possible reasons behind this are explored. Because air is directly delivered to the breathing zone, the indoor air quality under stratum ventilation is improved. Substantial energy saving can be achieved with stratum ventilation. Studies revealed that nine factors contribute to this saving. Some transient processes under stratum ventilation were investigated and useful results attained. Design guidelines are suggested.
