Human thermal adaptation in severe cold area (1):Field study in residential buildings

Conducts a continual field study in residential buildings in Harbin during the winter in five periods—before-heating period, early-heating period, mid-heating period, late-heating period and post-heating period. Continually monitors the outdoor and indoor air temperatures and humidity, combined with subjective questionnaires. Obtains the thermal responses and thermal neutral temperatures during the five periods. Finds that human thermal neutral temperatures in residential buildings change with the indoor and outdoor climates, and obtains many evidences of thermal adaptation.
