Applications Building automation harnesses intelligent energy monitoring The Grundfos “Living Lab” leverages smart energy monitoring and metering technologies using Microsoft Azure and TwinCAT IoT to create a database for optimizing building operations. Access to data can be defined and enabled for a wide range of groups including the building‘s residents and management. The Grundfos dormitory has a green profile, built following the low-energy class 2015 standard and very low consumption of energy. Grundfos has worked on implementation of advanced energy technological solutions with the aim of reducing behaviour-related consumption of energy to a minimum.

The dormitory is near the town‘s port district and was built in accordance with the most advanced energy efficiency standards and equipped with the latest building and automation technology. The energy monitoring system creates a database for optimizing building operations. By including the residents of the “Living Lab” in the project itself, the building owners can increase efficiency without reducing the residents’ comfort. First implementation The first version of the Grundfos project was implemented as early as 2012 by installing a special server infrastructure and database in the building. As the monitoring cycles grew shorter and the amount of data needed for the seamless analysis of current and historical conditions larger, administering this IT infrastructure became increasingly expensive in terms of both money and personnel. Protecting access to all this data by various groups of users also required increasingly complex systems. In order to meet these requirements in the future, the parties involved in the project decided in 2015 to redesign the project and migrate the server infrastructures to a cloud-based system. As part of this change, Beckhoff’s highly scalable control technology demonstrated its flexibility, providing a seamless retrofit of the local building automation platform with a link to the cloud. The PLCs and I/O subsystems now transmit the energy data to the cloud-based system via TwinCAT IoT software, which is easy to configure and does not require programming. Microsoft’s Azure cloud platform provides everything necessary to create a fast, scalable infrastructure for processing and storing the data. Access to the energy monitoring data from the “Living Lab” can be defined and enabled for a wide range of user groups. The information is made available to the building‘s residents and management, as well as to Connectivity with the Microsoft Azure cloud platform provides the functions necessary to create a fast, scalable infrastructure for processing and storing the data. Access to the energy monitoring data from the “Living Lab” can be defined and enabled for a wide range of user groups, and is available to residents and management. SOURCE: BECKHOFF
