| Summary: | Linpan is a unique livable ecosystem settlement in western Chengdu, China, that has existed for thousands of years. However, its living environment is deteriorating because of rapid urbanization. Improving residents' satisfaction with environmental quality through providing favorable thermal comfort is of vital significance for preserving Linpan. However, whether the existing microclimate conditions in Linpan actually meet the inhabitants' thermal comfort is not yet known. Therefore, this study combines an objective microclimatic monitoring approach with a subjective questionnaire method, to quantify the thermal comfort, and in a further step to investigate its relationship with inhabitants' thermal adaptation and thermal environment, for the outdoor (including public spaces and courtyards), semi-outdoor (referring to the spaces under eaves) and indoor (referring to building interiors) spaces of Linpan. The results show that the neutral temperatures for outdoors and indoors are 26.64 °C and 26.84 °C, respectively. Air temperatures for all these four types of spaces exceed the inhabitants' thermal comfort. Microclimates are found to have strong influences on thermal comfort in Linpan: underlying surface temperature has the most influence on public spaces; air temperature is the important determinant for courtyards, the spaces under eaves and building interiors. Local residents have stronger preference for improving the air temperature, relative humidity and wind speed outdoors than indoors, because they can adapt better to the indoor environment. Our findings contribute to determining better ways of preserving the Linpan settlement by clearly understanding its thermal environment and thermal comfort requirements.
•Thermal comfort characteristics of Linpan, a typical agricultural ecosystem settlement.•Current thermal environment of Linpan fails to meet the inhabitants' thermal comfort.•Impacts of microclimate parameters on the thermal comfort vary among different space types.•Improving the outdoor microclimate in Linpan is more effective to enhance thermal comfort that indoor. |
