Towards smart buildings performance testing as a service

Energy consumption in buildings accounts for ca. 40% of the world's total energy consumption, yielding a call for attention to their performance and improvement of their behaviour. The concept of performance testing has been developed as an approach to control, potentially lower, and bring awareness to buildings' energy consumption. In this paper we propose a methodology for continuous performance testing of smart buildings as a service. We discuss the automatic discovery and instantiation of performance tests, as well as usage of results for discovery of potential faults and ways to improve buildings' performance. The methodology that we present is sufficiently flexible to be extended to other cyber-physical systems, given minor adjustments. Finally, our proposed methodology has been partially implemented and deployed to a smart building at a university campus in Denmark, delivering promising results.
