Requirements
The operators of retail chains are facing a multitude of challenges. Among other things, it’s about the different equipment, such as heating and cooling to coordinate, monitor and optimize. The energy consumption of the individual systems must be presented transparently for this purpose.
Besides being able to use exact billing of energy consumption with allocation to individual cost centers and tenants also benchmarking of branches is required. These metrics can be used actively for external representation in terms of energy savings and the associated commitment to the environment and climate protection.
Objectives
The main objective of the use of an energy management system is to save energy costs. Many savings can be achieved by optimizing the already existing plant equipment. Furthermore steps must like the exchange of cooling or lighting equipment must be calculated in terms of their amortization. The familiar comfort – temperature, lighting and air quality – for customers and employees must be maintained.
A comparison of stores to each other about benchmarks is a key element of energy management.
Implementation with meterKiT
Basis of the energy data collection are the energy meters. These are usually connected by bus to a locally installed meterKiT Box and read out there. Here is also the preliminary evaluation of the data, which in turn is as well transmitted to the meterKiT Data Center. The transfer of this data is typically done once a day, wherby alarms and limit violations are immediately communicated to the meterKiT Data Center and then forwarded to the appropriate maintenance personnel.
Due to the integrated Web server in the meterKiT Box, the user has the posibility to access program schedulings or process charts and to be able to observe certain system conditions and to modify parameters.
The meterKiT Data Center stores the data in a powerful database, aggregating them and provides the data to users in the form of tables and graphs in a powerful Web-Frontend. These views allow the energy balance of processes and properties and are suitable and fully configurable for the particular user groups.
The meterKiT Data Center can be installed on-site at the customer site or provided from us as a hosted Solution (SaaS).
The meterKiT energy management system is fully scalable and allows the customer to expand the system at any time, whether by installing of a further store or by adding more data points.
