1. BIM-based wind-driven rain modelling using ISO 15927-3 and geometry-based exposureRichard Acquah, Jonas Niklewski, Jakub Michal Sandak, 2026, izvirni znanstveni članek Opis: Wind-driven rain (WDR) is a key source of façade moisture risk. ISO 15927-3 estimates WDR using static wall-factor tables, limited in scope and unable to capture façade-specific geometry or sheltering. This study introduces a BIM‑native workflow that dynamically computes wall factor as a geometry‑derived exposure fraction, evaluated per façade cell via ray tracing and power‑law‑based cell‑level height‑scaling factorization. Implemented in Revit, the method automates ISO corrections for terrain, topography, and obstruction, and outputs exposure fraction, wall indices, and catch ratio with façade-resolved visualization. For the cases studies presented, the BIM-Ray Tracing approach (mean absolute errors 0.03–0.06), achieved accuracy close to CFD and outperformed ISO 15927-3 with runtimes suitable for early design. While turbulence and edge recirculation remain better addressed by CFD, the workflow enables exposure mapping, rule-based checks, and integration with ISO 15686 service-life performance analysis.

2. BIM-based framework for estimating service life duration of wood construction elements under environmental exposureRichard Acquah, Jonas Niklewski, Anna Malgorzata Sandak, Jakub Michal Sandak, 2026, izvirni znanstveni članek Opis: As the construction industry adopts more data-driven and sustainable practices, Building Information Modelling (BIM) is increasingly used for energy analysis, lifecycle management, and maintenance planning. However, its integration with service life performance analysis especially for wood, a material susceptible to environmental degradation remains limited. This study presents a BIM-based framework that incorporates wood-specific parameters such as environmental exposure, material properties, and design detailing to estimate the service life of wood construction elements. The framework is structured using ISO 15,686–4 principles and implemented through custom Industry Foundation Classes (IFC) property sets. A Revit plugin developed in C# integrates the model into the BIM environment. A case study of a wooden playhouse is used as a proof-of-concept to demonstrates the framework’s ability to evaluate the impact of design, material, and environmental factors on service life. The results confirm that the framework supports service life prediction and enhances decision-making for wood-based construction. Twenty-one-month observations align with predicted results. However, long-term (2–9 year) predictions remain unvalidated, requiring extended monitoring. By integration of the service life prediction for fungal decay into BIM it offers a practical and scalable tool to support service life–informed design and planning for wood structures.
