RESEARCH ON THERMAL COMFORT IN OUTDOOR ACTIVITY SPACES FOR THE ELDERLY IN DALIAN CITY
The study selects four squares in Dalian to conduct on-site measurements and analyses of the thermal en-vironment for outdoor activities for the elderly.By measuring physical quantities and distributing subjective ques-tionnaires on thermal comfort,the research obtains trends in the thermal environment of outdoor activity spaces and the thermal sensation votes from elderly participants.Using Physiological Equivalent Temperature(PET)as the main indicator,the study analyzes the thermal perception and comfort temperature ranges of the elderly population in the outdoor activity spaces of the squares in Dalian.The results indicate that temperature is the primary factor affecting the thermal comfort of the elderly;however,their sensitivity to heat is relatively low,making it difficult for them to perceive the dangers of heat exposure.The neutral PET temperature is found to be 22.6℃,with the neutral tempera-ture range and the 80%acceptable temperature range being 18.76-26.45℃and 10.53-27.08℃,respectively.The acceptable temperature range is higher than the neutral temperature range,indicating that the elderly have a high tol-erance for thermal environments.The findings provide data support for creating comfortable thermal environments in outdoor activity spaces for the elderly and offer a theoretical basis for the development of age-friendly infrastructure and related research.
