An Automatic Aggregator of Power Flexibility in Smart Buildings Using Software Based Orchestration
This paper presents a software-based modular and hierarchical building energy management system (BEMS) to control the power consumption in sensor-equipped buildings. In addition, the need of this type of solution is also highlighted by presenting the worldwide trends of thermal energy end use in buildings and peak power problems. Buildings are critical component of smart grid environments and bottom-up BEMS solutions are need of the hour to optimize the consumption and to provide consumption side flexibility. This system is able to aggregate the controls of the all-controllable resources in building to realize its flexible power capacity. This system provides a solution for consumer to aggregate the controls of ‘behind-the-meter’ small loads in short response and provide ‘deep’ demand-side flexibility. This system is capable of discovery, status check, control and management of networked loads. The main novelty of this solution is that it can handle the heterogeneity of the installed hardware system along with time bound changes in the load device network and its scalability; resulting in low maintenance requirements after deployment. The control execution latency (including data logging) of this BEMS system for an external control signal is less than one second per connected load. In addition, the system is capable of overriding the external control signal in order to maintain consumer coziness within the comfort temperature thresholds. This system provides a way forward in future for the estimation of the energy stored in the buildings in the form of heat/temperature and use buildings as temporary batteries when electricity supply is constrained or abundant

Building Intelligence:Home operating system for smart monitoring and control
People spend most of their time indoors. This is why indoor air quality is one of the key factors affecting our health, activeness and quality of life. Buildings we are living in should give us comfortable and healthy conditions. Buildings equipped with HVAC-systems often operate using default settings with no automation installed causing problems in indoor air quality and building structures. In this paper one possible solution to overcome these problems is described. A solution proposed relies on novel wireless indoor monitoring system and controlling concepts of devices developed at VTT. Furthermore, similar concept of controlling devices is utilized in energy management
