WUFI-Bio: A Comprehensive Approach to Assessing Mould Growth Risk

In the realm of building science, understanding the risk of mould growth is crucial for maintaining a healthy and safe indoor environment. Mould growth can be triggered by various factors, including high humidity, temperature fluctuations, and poor ventilation. To address this issue, researchers have developed the postprocessor WUFI-Bio, a cutting-edge tool that enables the assessment of mould growth risk based on local climate conditions. In this article, we will delve into the world of WUFI-Bio, exploring its underlying principles, applications, and benefits.

WUFI-Bio is a novel biohygrothermal method that has been developed to assess the risk of mould growth under transient ambient conditions. This innovative approach is based on comparing the measured or simulated transient ambient conditions with the growth conditions required by fungi commonly found in buildings. By simulating the moisture content of mould spores and comparing it with the critical water content necessary for germination, WUFI-Bio provides a comprehensive understanding of the mould growth risk.

The WUFI-Bio method involves several key steps:

Data Collection: Measured or simulated transient ambient conditions, such as temperature, humidity, and air velocity, are collected and analyzed.
Fungal Growth Conditions: The growth conditions required by fungi commonly found in buildings are determined, including the optimal temperature, humidity, and air velocity ranges.
Moisture Content Simulation: The moisture content of mould spores is simulated, taking into account factors such as the type of fungus, the substrate, and the environmental conditions.
Comparison with Critical Water Content: The simulated moisture content of the mould spores is compared with the critical water content necessary for germination.
Risk Assessment: Based on the comparison, the risk of mould growth is assessed, providing a comprehensive understanding of the potential for mould growth in a given environment.

WUFI-Bio has a wide range of applications in various fields, including:
