Thermal environment evaluation and thermal comfort zone deviation ——a case study of Chinese seaweed house in summer

Abstract

Renewing the vitality of traditional ecological dwellings in the context of global carbon peaking and carbon neutrality targets has become one of the important topics in today's building sustainability research, and the evaluation of thermal comfort in traditional dwellings is the key to it. In this paper, one of the most representative ecological dwellings in the world, the “Seaweed House”, was selected as the research object. Firstly, the physical environment of a seaweed house in Dazhuang Xujia Village was measured from July 29 to August 3, 2022. Secondly, a thermal comfort questionnaire was conducted to grasp the current information of the thermal comfort in seaweed house. The results show that:1. The humidity of seaweed houses in summer is too high. 2. Residents have a thermally neutral temperature of 26.9 °C, an acceptable temperature region of (24.8–29.1 °C), and a thermally desired temperature of 25.8 °C. 3. The adaptive predicted mean vote (APMV) model suitable for thermal comfort evaluation of seaweed houses was developed. The results of the study provide a precise theoretical guide for the study of thermal comfort evaluation models in this region, and a useful reference for the study of the renewal and renovation of the seaweed houses.
