Abstract

Predicting the hygrothermal performance and mold risk using the simulation model is a vital technical aspect for developing domestically produced

energy-efficient

and durable wood-bamboo building materials. This study focuses on Structural Insulated Panels (SIPs) exterior walls. By constructing a wireless high-precision hygrothermal data acquisition system and utilizing building hygrothermal performance software

measured and predicted data on indicators such as air temperature

relative humidity at the composite construction interface layer

and moisture content of internal and external cladding materials were obtained. The study analyzes the hygrothermal dynamic response of exterior walls at the Beijing’s regional climatic conditions and predicts the risk of mold growth. The wireless high-precision building hygrothermal monitoring system operates stably

providing reliable data for real-time hygrothermal condition characterization and software simulation. Domestic wood-bamboo building materials used in SIPs exterior walls exhibit significant hygrothermal barrier effects

with an exceptional drying capability after extreme rainfall conditions. Precise predictions were made regarding the temperature

humidity

and moisture content distribution patterns within the SIPs exterior wall structural layers

as well as five-year trends. The total moisture content of the exterior wall and indoor temperature and humidity remains stable over the long term study period

during which the moisture content of recombinant bamboo and spruce cladding materials was consistently below 15%

therefore preventing mold growth. This research serves as a reference for the application and design optimization using locally produced wood and bamboo construction materials for the exterior wall systems.
