“…The bio-based wall construction includes in-fill straw bales and timber structural frames. As the thermal transmittance of straw bales is lower than 0.070W/mK [48,49], the thermal performance of the bio-based walls is significantly less than 0.20 W/m 2 K [50]. This is considerably superior to both the conventional wall construction and the construction standards in GB/T50824-2013.…”

Due to the cold winters in northeast China, the energy consumption of the rural residential buildings is much higher in this region than in other regions. In this study, the energy sustainability of bio-based wall construction is examined through applications in rural residential buildings. Comparisons of the energy sustainability of the bio-based wall constructions and the conventional wall constructions are evaluated using IESVE-2019 computational simulation. The results show notable reductions in heating energy requirements and coal use, which is the major heating source for rural residential buildings in China. The results show that reductions of 45.82–204.07 kWh/m2/year in heating energy requirements and more than 40% in coal use are possible through application of bio-based wall constructions. The application of bio-based wall construction will result in lower seasonal air pollution and coal use through straw burning in northeast China.

“…The other two steady-state methods which have been used in the straw bale studies are measurement using heat flow meter apparatus [25] based on ISO 8301, and measurements using small hot box apparatus [26][27][28] based on EN-ISO 8990:1994 or ASTM C1363-19 [29]. Thermal conductivity can also be measured comparatively quicker using transient method, such as transient plane source method [30], transient line-source method [31] and other method using thermal probe for measurement [32], though a more complex analytical process needs to be applied compared to steady-state method.…”

“…Due to the lack of the data of straw bales in the software, the data are from existing researches. Considering the property differences of straw bales in different researches [40,50,51], the thermal conductivity of straw bale is designated as 0.700 W/mK. Existing researches confirmed the high thermal mass of straw bale walls [29,52] with specific thermal heat capacity ranging from 1388-2000 J/(kgK) [53,54].…”

The Prefabricated Straw Bale Construction (PSBC) has been proven as one of the most efficient construction methods to achieve low-energy buildings with low environmental impacts. This research presents analysis of the rationale for using straw bale constructions in northern China and a discussion of feasible constructions of PSBC to meet the local building codes following evaluations of potential energy performance of domestic buildings with PSBC in severe cold regions and cold regions in China. The results show that the buildings with PSBC reduce both heating and cooling energy uses, as well as heating intensities across the severe cold and cold regions, compared to the domestic buildings with conventional constructions. The findings of this research will contribute to reducing energy consumption in building industries in China.
