Randomized trial develops a predictive maintenance framework for HVAC systems in hospitals, suggesting improved sustainability alignment.
Key Points
This study aims to create a framework for IoT-enabled predictive maintenance (PdM) that enhances HVAC maintenance decisions while supporting sustainability.
Mixed-methods design including a survey of HVAC practices and digital readiness
Expert interviews to assess feasibility and workflow integration
Development of a phased PdM framework based on findings from both phases.
High HVAC criticality identified, but limited digital infrastructure and skills were noted.
Preventive maintenance is prevalent; however, PdM is positively viewed if it fits existing workflows.
A system-agnostic framework was developed that includes sensing, analytics, and decision-support components.
