Abstract. With the development of the social economy, the reinforced concrete residences in
the Miao village in Guangxi were gradually appearing, which shows a threat to the traditional
wooden residence to some extent. Which one was more suitable for the local environment?
This paper investigated three representative residences in the Jiangzhu village, Liuzhou city,
Guangxi province of China. Residence No.1 belongs to an old carpenter's family was built
with traditional building materials (wood) fifty years ago. Residence No.2 was also a wooden
house with a history of over one hundred years. Residence No.3 was a recently built residence
with modern materials (brick and reinforced concrete). The temperature and humidity of these
three houses were measured respectively, and the results show that, in Guangxi Miao village,
the traditional building materials and constructions were superior to that of modern building
in terms of their indoor thermal performance.
1. Background
Thermal environment is closely related to the health and comfort of human. People have been trying
to improve the living environment by developing new technologies. However, through historical
screening, the traditional folk houses created by the ancestors uses various simple constructions and
local materials to cope with the regional climate and environment in different places. [1] This paper
compares and analyzes the indoor thermal performance of traditional residences and modern
residences in a Guangxi Miao village in China.
Located in the southwestern part of the hot-summer and cold-winter zone, the county is located in
the mid subtropical monsoon climate. Surrounded by mountains, the climate obviously turns like
mountain climate. In Rongshui, the weather is greatly influenced by monsoon and the heat and
humidity are intense. However, the climate is quite mild. The extreme maximum temperature was
38 °C in 2017. The annual extreme minimum temperature in the county was 3°C. The lowest
temperature in the cold mountain area was -4.1°C. The rainfall is abundant but not evenly distributed.
The four seasons are uneven. Summer is the longest, then winter and the shortest season is spring.
The annual total evaporation was 1478.2 millimeters. [2]
Rongshui always has the reputation of "the kingdom of China fir ", which means it is rich in the
resources of China fir. Besides, China fir has good quality and toughness which is suitable to be used
as building materials. Therefore, the traditional building and furniture in this area mostly use China
fir as raw materials forming a very local style stilt house (Figure 1). The advantage of the stilt house
