Xella International GmbH is a corporate group with head office located in Germany. Their main profile is manufacturing and marketing building materials, gypsum fibreboard and cement-bonded dry lining panels together with lime and limestone. The following case study was completed for one of Xella’s Eastern European centers. The aim was to provide a hands-on energy management system solution for the production of Ytong building material.

The process involved the assessment of the current situation, discussing the potential new energy efficient technologies and measures, setting objectives on energy savingscarbon dioxide savings, weighing up the investment costs, operation and maintenance costs for each production line, unit and finished product The client was particularly interested in knowing the exact energy consumption and therefore cost per product, which was easily achievable by using AVReporter Energy Management Software.

The main energy management software requirements were:

  • XELLA requested an Energy Management and Monitoring system, which is capable of keeping track of their consumption at specific measurement points.
  • These measurement points are mostly related to the production. The measurements contain gas, electricity, heat and water consumptions.
  • Allowing users to create their own customized consumption reports, tendency analysis on the web, without the installation of any software to the users’ computers was also an important factor.
  • End-users should be able to access information on the web without the need of installing any software to their PC.
  • Finally XELLA requested automatic report creation based on their daily, monthly and annual energy consumptions.

About the Energy Management System’s structure:

  • Establish optimum communication with different type and make of field power meters, logging their historical data into database for later analysis.
  • Three PLCs (Modbus TCP/IP compatible through Ethernet) were used as gateways collecting the consumption data of gas, heat, compressed air and water meters. These three PLCs are connected to the server.
  • The system also contains a GPRS modem for power plant heat measurement.
  • Integration of virtual AVReporter server equipped with AVReporter Lite Edition and Webpublisher
