Low-cost sensor network in cognitive buildings for maintenance optimisation

Buildings cannot perform without a proper planning, execution and monitoring of Facility Management services. Moreover, occupancy monitor procedures for cognitive buildings are gaining momentum in performance optimization through dynamic adaption of indoor conditions (e.g. temperature, humidity, shadings). In this article, the application of a similar approach for automated execution of maintenance contracts (e.g. cleaning services) is presented. This approach is allowed by monitoring occupancy, through an ultrasonic sensor network. The methodology has been validated on a case study, concerning an office building in Milan, Italy.
