Indeed, the platform aims not only at monitoring consumption but also actuating the equipment. The control strategy is defined as relying on data from sensors and simulations, considering as constraints the comfort for people in the building. The solution has been applied to a real scenario, namely, one of the medical centres of Humanitas Medical Care, the Fiordaliso Medical Centre, situated within a commercial centre in the south of Milan. More specifically, sensors were installed to monitor the main variables related to the comfort of the occupants (temperature, carbon dioxide (CO<i>2<\/i>) and humidity), energy consumption, and the status of the machines for heating, cooling and air conditioning. Then, an alerting system was implemented to automatically intercept anomalies from the data.<\/p>\n<p>Finally, Machine Learning (ML) models have been developed and applied to simulate the building behaviour and predict the evolution of the parameters of interest. Thus, the monitored and predicted parameters are aggregated to define the optimal control strategy.<\/p>\n<p><iframe loading=\"lazy\" title=\"Evogy - DIH4CPS\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/po3cHe7k3aU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>The experiment targets concerning model accuracy and energy consumption reduction have been reached, even considering the restrictions introduced due to the pandemic that enforced higher air quality standards:<\/p>\n<p><strong>1.
