Study on air tightness and thermal comfort of high-rise Glulam structure buildings

Abstract

ABSTRACT Building air tightness, indoor temperature, and humidity moment affect the building indoor personnel’s subjective comfort. Therefore, this article takes a six-story Glulam post and beam with shear wall construction as the main test object, with a light wood frame construction house and a log house in the same area as comparison objects. The research conclusion shows that the air change frequency of the tested building is 4.64 h−1, which is consistent with the normal situation; the air tightness is good. There are thermal bridges at the building nodes of each structure type. The joints of the enclosure structure members have a certain influence on the generation of thermal bridges. Compared with the comparison objects, the building has the best thermal insulation performance, the most stable indoor temperature and humidity, and the best way to keep the indoor environment at a more comfortable stage for the human body.
