Paper Title
Improvement of the Energy Efficiency of Passive Elements using Smart Sensors: IOT

Abstract
To optimize thermal performance of passive elements inside the building as a whole of its results is not yet achieved due to fluctuations and internal generation. To identify the energy need. This research work aims to improve the consumption behavior of a building located in the city of tangier. to automate and control this building. IOT allows to better exploit and collect the data of the building and consists in a simplified way in connecting the objects. this is the ability to interconnect the objects and make them interact with their physical environment, which also allows a good control of the behavior of active and passive consumers with regard to energy consumption Keywords - Energy efficiency, IOT, Energy behavior, PLC, energy saving
