Research on Thermal Environment Evaluation of a Traditional Brick-Timber House in Daokou Town of the Northern Henan in Winter

Learning the status quo of thermal environment comfort is necessary for the renewal and retrofit of traditional buildings. At present, physical environment measurement and subjective survey are the basic methods of thermal environment evaluation, but the different emphasis of decision-making model between them leads to the obvious difference of evaluation results. Taking the typical brick-timber dwellings of Daokou Town in North Henan Province as an example, the research data were obtained by combining the results of wind environment simulation, physical environment measurement and questionnaire survey. PMV, APMV, adaptive thermal comfort model and thermal sensation were used for evaluation and comparative analysis. The research showed that: 1)there was a big difference between the residents’ subjective feeling about the thermal environment and the objective evaluation. From the evaluation results, the APMV model were closer to the thermal sensation; 2)residents’ cold adaptability was an important reason for the difference between evaluation results of different models. Considering residents’ desire for thermal comfort, the thermal adaptability as well as thermal preference of local people should be fully considered in renewal and transformation process; 3)the status quo of indoor thermal environment deviated greatly from the thermal comfort standard of urban residential buildings, so it was not suitable to adopt urban standards to improve the thermal environment of traditional dwellings; 4)the air tightness of enclosure systom, the fluctuation of indoor temperature, and the protection of historical building style were important concerns in the renewal and retrofit process of traditional dwellings.
