The thermal comfort of open environment is formerly investigated into indoors, and globe warming caused the temperature increased to research critically thermal comfort of humans in outdoor spaces. There are many estimated indexes WBGT, GT, MRT, SET*…etc. which approved no definite international indexes for researching outdoors in the thermal comfort of open environment that reasons are different geography, racial humans and favors in comfortable ranges of gauge indexes. It is imperative to make sure conditions of humans comfort in semitropical Taiwan, and connect international various climates of thermal environment areas. The purpose is to explore humans use the improvement method for planning the campus of outdoor environment in the situation of comfortable/uncomfortable temperature.
This research is proceeded outdoor thermal environments with and without leafy shade in junior and senior high schools of Taichung city to collect 1848 usability samples by questionnaires inquired about information of thermal sensation and used instruments to record the temperature, radiation temperature, humidity and wind speed between September 2007 and January 2008 and February 2009. Interviewees were preferred the temperature range 25.9℃ negative 3~4℃, interviewees were deemed subjectively that plants were very important effectively and hoped to use live plants improved outdoor environment for thermal comfort of outdoor environment in questionnaires of analyzing thermal sensation item and expectations item. Analysis results from the liner regression method descried neutral temperature for campuses of with /without leafy shade are 25.2℃and 24.8℃ respectively; in junior high school, neutral temperature is 25.1℃, the senior high school of neutral temperature is 25.9℃. The favorite temperature appeared in campuses for with leafy shade is 21.2℃ and without leafy shade is 21.8℃; the preferring temperature of junior high school is 20.8℃, the favorite temperature is 21.6℃ in senior high school.
The research results contemplated user’s comfortable expectancies and cooperated to design mainly the guide method of live plants for improved the campus of outdoor thermal environment when it’s referred basic data for planning the prime campus.
