Field study of meeting thermal needs of occupants in old residential buildings in low-temperature environments using personalized local heating

The outdated structures and heating devices in old residential buildings can no longer functionally meet the thermal needs of users and require reasonable supplementary measures to meet the demand. Personalized local heating, owing to its thermal comfort and energy-saving performance, is a good solu...

A field study was conducted with 16 participants in typical old residential buildings under different conditions from January to February 2023. The findings revealed that all personalized local heating methods could increase the overall thermal sensation of participants at background temperatures of 16 degrees C and 19 degrees C, but only a few of them were effective in enhancing the participants' overall thermal comfort.
