A multi-domain simulation approach for enhanced indoor environmental quality in offices: Challenges and opportunities

Abstract

As occupants experience simultaneous stimuli from multiple environmental domains, integrating multi-domain simulation practices can significantly enhance decision-making in the building design phase. This study introduces a multi-domain simulation workflow, merging thermal, visual, acoustic, and air quality domains to evaluate IEQ in offices. A case study uncovered significant challenges in integrating the various domains, underscoring the need for better interoperability between simulation tools. Systems, boundaries, and fluid dynamics shape the interplay between thermal, acoustic, and air quality. Besides, the thermal and visual domains emphasise the need for a holistic approach that also considers the influence of outdoor climate on indoor environments. This comprehensive approach supports initial design processes while highlighting the relevance of detailed multi-domain interactions.
