Demonstrating Automated Fault Detection and Diagnosis Methods in Real Buildings: International Energy Agency. Energy Conservation in Buildings and community Systems ANNEX 34

This report summarises the work completed during Annex 34. The objective of the Annex was to develop HVAC fault detection and diagnosis tools, which are close to commercial products. The approach was to design a number of different computer-based demonstration systems that could be interfaced to HVAC processes in real buildings. By monitoring the operation of these demonstration systems, researchers were able to test a variety of fault detection and diagnosis methods and techniques in a real environment, find possible shortcomings and obtain new ideas for further development. Over fifty industrial partners, including controls and plant manufacturers, construction companies, and building owners and operators, participated in the thirty demonstrations that were completed. The report describes each demonstration system, identifies key issues associated with successful practical application and examines the potential for commercial exploitation. The programme of research, which involved research engineers from eleven countries, was completed in under four years. Annex 34 was coordinated through IEA's Energy Conservation in Buildings & Community Systems Programme.
