The psychological effects of different types of housing environment under different weather conditions

In order to improve the quality of human being’s living and working environment, different types of wood structure building, ecological architecture and green building are advocated due to their lots of advantages. This study compared three types of houses in different weather conditions on people’s psychological and physiological indexes. The results showed that the temperature, electrocardiograph, heart rate and respiratory rate of people in different types of housing environment are different. Most of the physiological indexes in structural glued laminated and wood structure environment were better than those in steel and concrete structure environment, and most of the physiological indexes in structural glued laminated environment were better than those in the timber structure environment. It means that subjects of the test are easy to had comfortable and relaxed feeling in the glued laminated and timber structure environment. This provided theoretical support for the use of the product by scientific and efficient ways, and guidance for design and application of the construction of the wooden structure environment in the future.

Effects of different types of housing environments on the physical index and physiological index

The aim of this present study was to promote the quality of living environment, and create a healthy living environment through advocating for low carbon and green buildings. An additional aim is gaining recognition for wood structured housing, thus gaining recognition in customers and consumption to further promote the green ecological and sustainable development of wood structured houses. This work examined the physical environment indexes and physiological indexes of the participants in three different structure types of housing environment with behavioral analysis (CAPTIV) and environmental data (BAPPU) synchronous test system. The results of the MANOVA revealed a significant main effect for the housing environment indexes with temperature, moisture content, noise, illumination, air flow rate and skin temperature, ECG, and respiration of three different structure types (log, glulam, reinforced concrete). In comparison, the influence of the physical environment factors in both the log structure and the glulam structure housing were better than the reinforced concrete structure housing. It indicated that woody housing environment was benefit to the health of habitants. Participants were interested in the log structure and glulam structure housing environment with joy and comfortable feelings. Different proportion of building environment and interior wooden decoration proportion can influence different cognitive and feelings of habitants. Therefore, wooden housing environment is helpful to adjust emotion, relieve work pressure and improve tasty, which would provide people with both physical and mental benefits.

Effects of different flame retardant treatments on the combustibility of bamboo filament

Bamboo filaments were treated with boric acid and borax (the mass ratio of 1:1, the concentration of 20%) with four different treatment methods including atmospheric immersion, cold and hot bath immersion, vacuum impregnation and vacuum-pressure impregnation. The different treatment methods on the boron loading were analyzed and the corresponding flame resistance of bamboo filaments were evaluated by the cone analysis. The results showed that suitable treatment method with optimized processing indexes, such as hot and cold bath immersion in the condition of 100°C/2 h and 20°C/2 h with 3 cycles, was more credible to accelerate the percentages of boron loading in the bamboo filaments, and the lowest result was found in the samples with vacuum impregnation. Compared to the untreated samples, the heat and smoke release would be decreased significantly, especially for the samples with the promising hot and cold treatment, and promising pressure treatment, attributed to the more stable boron fixed in the bamboo filaments.
