Understanding the energy consumption of buildings is crucial in achieving savings. Only if the Facility service knows exactly how much energy is consumed by which system / installation and in which area of the building effective investment measures can be developed that will ensure the best result.
Energy Management Tasks:
Accounting for the consumption of all types of energy and resources in real time, which goes beyond fixing the total energy consumption of a building. It also includes consumer monitoring to understand where, when, and why energy and resources are being used. Data collection should be carried out both from the side of generating equipment and connections to external networks, and from end users.
Providing data on the volume of energy consumption, both in absolute and in relative values, convenient for understanding and comparison. Different users may perceive energy consumption differently. For a manufacturing enterprise, energy can be measured, for example, as “kilowatt hours (kW * h) needed to produce a unit of production,” for a hotel, this can mean “kW * h per guest and an hour in the room.”
Part of the conversion process is the elimination of external influences, which makes it possible to compare the energy consumption in different buildings or under different conditions. This may include, for example, the specific energy consumption per square meter of a building or the consumption of engineering equipment, such as a refrigeration center, for generating a kilowatt of cold. Consider weather conditions to show energy consumption and its dependence on external weather conditions.
Using mathematical models to calculate key performance indicators and monitoring buildings.
Maintaining a database of energy indicators for the purpose of their storage, accumulation and use for a period of time sufficient to generate analytical reports.
Converting information into a “readable”, easy-to-understand (mostly graphic) view. Generating reports that make it easy to detect anomalies in energy consumption and provide tools to identify their root causes.
Continuous implementation of the above tasks helps not only to identify optimization opportunities, but can also be used to verify the return on investment in building modernization. Efficient energy management is not only financially beneficial, but also becomes a mandatory legal requirement.
Energy management methods aimed at saving energy, reducing costs and meeting environmental requirements are outlined in the international standard ISO 50001. Building Automation Systems (BMS) cover all aspects of energy management, from data collection through conversion and archiving to reporting and analysis of energy consumption, and are the main tool to achieve the ISO 50001 standard.
To monitor basic consumption data, automated systems contain a wide range of equipment, and analytical software modules present data in an understandable form. The intuitive presentation of information allows you to plan for improvement efficiently.
