SERVICE AND MAINTENANCE
objectives are maintained at all times, as well as identifying any faults that prevent these objectives from being achieved. They also guide the possible adoption of corrective measures regarding the management of the building-system (such as the switch-on times for the air conditioning and lighting systems, continuous adaptation to demand of the flow-rates of hydronic and air circuits, variable ventilation rates based on the concentration of pollutants in the environment, limits in the supply of heating or cooling energy in unoccupied environments, etc.).
Creating value with the power of data For some time now, the ability to be able to connect to the Internet has been natively available in control and integration systems. IoT therefore means moving from isolated systems to solutions in which the different devices are interconnected and exchange data with each other. The advent of IoT represents a phase that will see a further increase in efficiency levels, and therefore results in terms of cost reductions. This is contributing to greater availability of long-term data relating to energy performance and indoor air quality of buildings. Such data may come from different sources and relate to the total energy performance of the building,
systems or components, the energy produced on site from renewable sources, and to the variables that have an influence, including those relating to the behaviour of occupants. The consequence of this trend is an exponential growth in the size and complexity of the databases relating to buildings-systems, which when correctly analysed can lead to the definition of the true performance of the building and optimisation of its operating performance.
The vast amount of information collected in the field can be used to create a new class of higher- level applications that, operating transversally using different sources, can provide new decision-making tools to stakeholders in the sector. Extensive and massive digitisation in the field of energy management and indoor comfort of buildings is a topic that may be of particular interest at all levels,
from design to management and the end user of the building. With IoT functions, solutions can be implemented, for example, to determine the building’s energy performance, carry out predictive maintenance on the equipment, and integrate with the electricity grid to improve energy usage when the best availability is expected.
Control, integration and monitoring of systems is an opportunity to make your building smarter, with a view to saving energy and improving performance, especially in existing buildings.
The benefits far outweigh the costs, and the return on investment makes this solution very effective. With the advent of IoT solutions, buildings generate a large amount of data that can become an asset for all of the players in the supply chain, used to create value through the provision of new services or the reduction of costs for everyone involved.
