Talk title: Estimation of presence of hazardous substances in the existing building stock using machine learning on building specific data
The research group has developed methods for predicting characteristics in multi-family buildings using machine learning methods on large-scale data from the Swedish building stock. The predicted results have been used as input to get better cost estimates for renovation strategies in the building stock. Hazardous substances are typically observed during the actual renovation, and can increase the renovation costs several fold. So, knowing this information beforehand is advantageous when deciding on appropriate renovation measures. Machine learning tools have not yet been used to automate predictions for the presence of hazardous materials in building components before. The absence of centralized storage of environmental inventories and decommissioning inventories is a crucial reason. Sweden is unique in terms of the requirements for carrying out environmental inventories and demolition inventories prior to rebuilding and demolition. Unfortunately, this information has only been stored by property owners and urban construction offices and environmental administrations and not at national level. In this project, important is done to collect and systematize observations to make them useful for machine learning.
