A computer program for ASD system design applications in large buildings radon mitigation
- Univ. of Florida, Gainesville, FL (United States)
Many practical applications for reducing elevated indoor radon concentrations depends on the utilization of active soil depressurization (ASD) systems such as the Sub-Slab Depressurization system. Applications of these systems for radon mitigation in large structures such as schools, hospitals and commercial offices are significantly more complicated than applications in residential structures due to the complexity and features of large buildings. A computer program has been developed to aid in designing and selecting appropriate ASD systems for large building radon mitigation practices. The program is based on mathematical modeling of the pressure distribution in the sub-structure system that utilizes solutions of the continuity and pressure equations in porous media. The model predicts the pressure field extension (PFE) developed by forced pressure point(s) applied to the sub-structure system. The program utilizes finite difference solutions to visualize spatial dependency of PFE that might be generated by ASD system design and configurations. The program has been developed using an extensive graphical user interface to facilitate easy utilization by ADS designer and radon mitigators. The program is capable of providing 3D PFE maps and system efficiency assessment for large structures incorporating different features such as slab size and shape; suction mats size, shape, and orientation; grade beams; and structure foundation. The program provides a significant tool for the design and application of ASD systems for radon mitigators.
