Location: IHK Dienstleistungszentrum Rosenheim (Germany)

Target audience: SMEs

Number of participants: 15

Workshop topics

The workshop “TOP 5”, which was held at the chamber of commerce in Rosenheim, was the opening session of a series of workshops that are starting within the “industry working group” of the installed ROC ezro. There were five main topics that were discussed:

  • TOP 1: Analysis of energy consumption and indicators
  • TOP 2: Purchasing energy and load management
  • TOP 3: Efficiency of main consumer
  • TOP 4: Efficiency of the building shell
  • TOP 5: Motivation of staff

Workshop outputs

Ms. Carmen Cretnik opened the workshop with one of the TOP-5 topics and stated out the importance of an Energymanagementsystem (EnMS). According to the experiences Ms. Cretnik made, enterprises that already use an EnMS raise huge potentials to reduce Energy-consumption and –costs. There are many systems that can be adopted, such as the DIN ISO Certifications and the EMAS-System, public platforms such as mod.EEM or even the LEEN-method. Taking into account the aspect of environment there are labels such as ÖKOPROFIT, which is available for enterprises as well as for private people.

The first part of the workshop concentrated on reasonable methods to gather information on energy consumption and indicators of enterprises. It turned out, that many of the participating enterprises are already analyzing their energy consumption. Compared to big enterprises, especially small and medium-sized companies have difficulties to raise detailed information on certain energy indicators such as specific installed lighting-power or energy consumption of their IT-services due to the lack of expertise and time. Ms. Cretnik introduced a minimum required dataset, which enterprises should record in any case. She also stressed out the importance of a good data visualization at least for the most important energy flows in companies.

The second topic was concerned with possibilities of purchasing energy and load management. Both of them are good methods in order to reduce charging of energy costs. In Germany, certain enterprises with high energy demand can be relieved of the so called “EEG-Umlage”, a model to rededicate the costs for the implementation of a 100% of renewable energies in Germany. According to Ms. Cretnik, a very important first step is to analyze the load profile. It is important to measure the total and specific load of the electric consumption with an interval of 15 minutes in order gather information on the real load profile. Cutting off very few, but high peaks in that profile can reduce costs for the electric allocation. A very good way to visualize the peak loads is the annual load duration curve, a graph where all measured data is arranged by the value. Another way to reduce energy costs is the opportunity of participating at the European energy stock exchange.

One of a very important model to save energy in enterprises is the efficiency of the main consumer. Those companies that are looking for possibilities either to sell or to buy industrial waste heat can look on the Energieatlas Bayern, an online platform that shows all potentials concerning renewable energies in Bavaria. Especially the combined heat and power can be very useful for industrial companies that have demand for both energy sources. Regarding the technology of a BHKW, it is very important to make sure runtime hours of at least 5000h per year. Ms. Cretnik demonstrated all possibilities of a funding of energy efficient technologies. A very good platform is the Ms. Cretnik concluded this topic by introducing different guidelines sich as the internet platform [1].

The fourth part was concerned with the topic of the efficiency of the building shell. Although this topic is already well known by the enterprises, there are many restrictions for implementing a complete renovation of the company’s buildings. One of the reasons, why companies hesitate renovation still are high investment costs. Ms. Cretnik pointed out the importance not only of the heating demand in the winter but also the advantages of a good building shell in the summer. She also informed the attendees about the possibilities that the IHK gives for free such as the energy consulting.

The fifth and last topic concentrated on the motivation of staff. Ms. Cretnik demonstrated very simple but effective methods how motivated staff can help to reduce the energy consumption by their behavior. At the same time, this would also lead to a very positive external communications for the companies. There exists a very good guideline from the LfU „Mitarbeitermotivation für umweltbewusstes Verhalten“.
