Stabilization of media costs by reducing consumption

By introducing energy management media consumption are to be reduced continuously and sustainably. The aim is to lower the consumptions by 10 to 20 per cent based on today’s requirements. Electricity and district heating with annual consumptions of 6.5 GWh and 3.5 GWh, respectively, are in the focus of the optimization measures.

The measures range from adjusting organizational processes and a utilization management for the different resources to technical measures to minimize consumption.

Reduction of media costs by producing energy

A further aim of the energy management is to reduce media costs by producing energy at the institute’s location. In this process, renewable energies like photovoltaics and power-heat-coupling play a decisive role. According to initial calculations energy procurement costs may be lowered by 10 to 20 per cent.

Improvement of carbon dioxide balance

Reduced media consumptions as well as the planned electricity generation lead to a drastic lowering of carbon dioxide emission. This would accommodate the “green research” at the institute.


Here, you can find some concrete measures of the institute to reduce energy consumption.

Energy management team

Since February 2013, our energy management team meets regularly once a month to coordinate the energy saving measures and to implement them in the departments.

The members come from all departments and serve as contact persons for all institute employees, who are interested in this topic and want to influence it.

Main task of the team is to evaluate, prioritize and discuss the numerous ideas regarding the optimization of energy consumption and to control their implementation. Furthermore, each member of the team is a multiplier of information concerning the energy management for his/her organization unit.

The representatives of each department are:

Energy data acquisition

The detailed acquisition of energy flows is the most important basis for analysis and for the resulting measures to reduce the consumption.

At the institute, electricity meters at main distribution frames and special major consumers are currently installed. For example, all phytochambers, Arabidopsis breeding cabinets and large refrigerators are recorded separately. Starting midyear 2013 the data will be made available to all staff with access to a PC using a web-based tool.

Furthermore, a mobile ammeter in each department allows analyzing electricity consumption of the individual consumers and, if necessary, reducing the consumption by organizational measures like better utilization, deactivation if not required etc.

Capacity management

Capacity management serves visualization and transparency of the occupancy of plant growth chambers in house N2.

The introduction of a test version with several selected chambers is planned for the third quarter of 2013. When the tool is established successfully, it will be expanded to the phytochambers in house B, N2 and P in the course of this year.

The aim is to minimize the number of activated plant growth chambers by improving their capacity in order to save energy. Furthermore, the tool allows detecting activated chambers that are not used. Based on a detailed analysis of the capacity data for future investment planning can be generated.

Collection of ideas

The collection of ideas is a tool for all employees at our institute to get an overview over already existing concepts and measures for optimization.

At the same time new ideas can be collected. These will then be evaluated and usefully implemented by the energy management team. The tool allows prioritization and transparency of measures around energy management. From the middle of this year on, it will be available for all employees in form of a web-based tool in our intranet.

Cooling strategy

A central cooling strategy for our institute contributes to preventing the inefficient use of cooling generators and consumers as well as to regulating them sensibly.

With approximately 30 per cent, cooling represents one of the major electricity consumers. Currently, the institute harbors refrigerating capacity of about 1.5 MW. In summer this is needed completely for climate control in phytochambers, green houses and laboratory buildings. For the future, a strategy is pursued that will allow supplying energy to several semi-centers from one major energy center.
