Abstract
Integrating building information modeling (BIM) with Internet of things (IoT) technologies significantly enhances facility management (FM) by enabling advanced real-time monitoring of indoor environmental quality (IEQ). However, technical complexity, proprietary limitations, high software costs, and unclear long-term benefits hinder practical adoption. This study suggests a way to combine BIM and IoT using open standards like IFC and JSON, simple programming tools like Node-RED, and secure cloud services. A case study of a six-story office building showed that real-time IEQ sensor data can be combined with organized BIM information, helping to make better decisions about maintaining, replacing, or upgrading heating, ventilation, and air conditioning (HVAC) systems. This integration offers essential data needed for using advanced analysis techniques, specifically tackling issues with compatibility, ease of use, and organizational challenges, which is especially advantageous for small-to-medium-sized office buildings. Nevertheless, this study faced limitations due to restricted real-time data access from existing building management systems and preliminary predictive analytic capabilities, highlighting a need for improved direct data integration and robust analytical methods in future implementations.
