Integration of fault detection and diagnosis with energy management standard ISO 50001 and operations and maintenance of HVAC systems

Fault Detection and Diagnosis (FDD) has become a robust scientific field offering proven methods for the optimization and more effective operation of HVAC systems. However, FDD practical application faces several difficulties and barriers: legacy systems may be unable to provide meaningful information for FDD, integration of disparate systems can be difficult but also the organizational culture and existing contractual frameworks may present obstacles for innovation and industry acceptance. This paper presents a practical implementation of an stakeholder-centered solution called the CASCADE Implementation Kit that integrates FDDinto a comprehensive energy management system. Two major European airports will be the test bench of the CASCADE solution. Airports role as criticalinfrastructures and main energy consumer is also discussed in this paper. The solution delivers a common integrated platform including several innovative commercial and under development tools including an ISO-500011 energy management software, advanced data visualization, and building performance simulation.
