BIM Integrated Sustainable and Resilient Building Design Framework for the Northern Climate
Abstract
In austere environments like northern regions, remote communities confront myriad challenges, including permafrost warming and a substantial infrastructure deficit. This dissertation embarks on a comprehensive exploration aimed at enhancing the sustainability and resilience of buildings in the northern climate. The first study introduces an innovative framework integrating Building Information Modelling, Computational Fluid Dynamics (CFD), and heat transfer analysis. This framework quantifies the effects of infrastructure development on permafrost ground, revealing that building characteristics such as clearance height, soil properties, and thermal conductivity significantly influence the ground thermal regime. Recommendations include raising buildings by one meter to reduce thermal stresses on permafrost. The second study delves into the thermal performance objectives of elevated buildings in permafrost regions amid climate change. Ultra-high-resolution regional climate simulation-driven CFD models inform a detailed investigation, indicating that elevated buildings can disrupt permafrost’s thermal equilibrium, affecting ground temperature gradients and increasing air and ground temperatures. The study emphasizes the importance of exploring the neighborhood scale in building design and planning within permafrost regions. The third study assesses the thermal performance of buildings within permafrost regions using CFD convective heat transfer simulations integrated into Building Energy Simulation models. Results underscore the complexity of design considerations in northern climates, with a 26.74% difference in energy consumption between ground-level and elevated structures. The dissertation concludes by advocating for future research to optimize design solutions tailored to the unique challenges of buildings in permafrost regions.
