Case Studies

Every task which we take on for our customers offers a new challenge. Each time the focus is set on different services from our portfolio and different details. With these case studies we introduce you to selected projects which are exemplary for the services we provide.

  • Maschinenbau Lienenbrügger GmbH

    Project: Introduction of energy-management system

    Maschinenbau Lienenbrügger (lidu.de) has been a contract manufacturer for high-quality engineering solutions for over 70 years. At this long-established company, STF Energy introduced an ISO 50001-certified energy management system while production was ongoing. The client‘s priority was to reduce operating costs. Based on extensive metrological inspections and an analysis of the potential tax savings, STF Energy developed an energy-measurement concept.

  • Härterei Reese Bochum GmbH

    Project: Introduction of an energy-management system

    As a player in the metal processing industry, Härterei Reese (haerterei.com) is a particularly energy-intensive company. STF Energy developed an ISO 50001-certified energy-management system for Reese to help it improve its energy efficiency and lower its energy costs. In order to develop appropriate cost saving measures, we had to create complete transparency in all areas of the company’s energy consumption and use. In view of the complex processing procedures, the analysis was particularly challenging. Thanks to the implemented efficiency measures, the company’s energy targets were met.

  • Stadtwerke Düsseldorf AG

    Project: Energy-efficiency analysis for a Stadtwerke client

    Stadtwerke Düsseldorf (swd-ag.de) is the largest energy provider and energy-service provider in the Düsseldorf region. STF Energy conducted an energy-efficiency analysis for an important client on behalf of Stadtwerke Düsseldorf. The analysis involved an inspection of all relevant equipment and an evaluation in terms of energy consumption. This allowed us to give the client a greater insight into its energy usage.

  • Rhein-Ruhr-Malz GmbH

    Project: Introduction of an energy-management system

    Rhein-Ruhr-Malz GmbH (schillmalz.com) contracted STF Energy to implement an energy-management system in order to significantly reduce its energy costs for several locations. We conducted comprehensive measurements and drew up an action plan. The consumption analysis of the malting plant proved particularly challenging. The objective was to make the drying process as transparent as possible in terms of energy consumption and usage. Our STF experts successfully implemented an ISO 50001-certified energy-management system, and the subsequent exemption from the EEG levy was particularly appreciated by the client.  

  • Pietsch Bochum GmbH & Co. KG

    Project: Specialist planning of technical building equipment for new facility at Elspermann Großhandels GmbH & Co. KG

    The Pietsch Group (www.pietsch.de) is one of Germany’s leading wholesalers in sanitary, heating and air-conditioning technology with over 50 locations nationwide. STF Energy assisted Elspermann Großhandels GmbH & Co. KG, a Pietsch Group subsidiary, with taking advantage of the full energy savings potential at its new building in Bochum. STF carried out the specialist planning for the heating, plumbing, ventilation and air conditioning. With the development of a comprehensive energy concept including an air source heat pump (Monovalent), the project was successfully completed with an EU GreenBuilding-programme certification.

  • Fressnapf Tiernahrungs GmbH

    Project: Specialist planning of technical building equipment for construction of the “Fressnapf-Akademie” building

    STF Energy assisted Fressnapf, Europe’s largest retail chain for animal food, with its new “Fressnapf-Akademie” building. During planning, STF experts were instructed to take the heating, plumbing, ventilation and air conditioning into account as extensively as possible. STF Energy drew up a comprehensive energy concept taking into account the statutory requirements. Gas-fired heat pumps for heating and cooling to ensure controlled temperature and thermostatically controlled air inlets were integrated into the building. With the help of STF Energy, Fressnapf now boasts a new, modern and energy-efficient Fressnapf academy.

  • KERKHOFF GmbH

    Project: Development, calculation and implementation of a heating facility for the historical Surenburg castle of in Riesenbeck

    On behalf of KERKHOFF, STF Energy provided the concept, cost calculation and implementation for a heating system at Surenburg castle in Riesenbeck. The objective was to achieve the client’s energy-efficiency requirements while taking into account the high security standards as well as the specifications for historic landmarks. In addition, the STF planners had to consider the different energy users, such as the castle, the hotel and the swimming pool. With the help of STF Energy, the castle was successfully equipped with a highly energy-efficient and flexible heating system.

  • VIVAWEST Wohnen GmbH

    Project: New “Exerzierhalle”: New residential construction with 69 housing units with integrated underground garage for 169 parking spaces

    VIVAWEST (www.vivawest.de) is Germany’s third-largest housing provider with 120,000 residential units. For the construction of 69 new units with an integrated underground garage, STF Energy is assigned with the technical building equipment planning. STF specialists are developing concepts for the heating, ventilation, plumbing and electrical system. The building project is currently underway.

  • Stroetmann Grundbesitz-Verwaltung GmbH & Co. KG

    For L. Stroetmann GmbH & Co. KG’s new administration building, STF Energy was responsible for the technical building equipment planning, which included the heating, ventilation, plumbing and electrical systems. STF developed a concept that involved the use of near-surface geothermal power for heating and cooling. The building project was successfully completed in December 2013.

  • Stadtwerke Krefeld AG

    Project: Rough energy analysis to achieve reduction in energy consumption

    STF Energy conducted a rough energy-related analysis of Stadtwerke Krefeld’s technical building equipment. Based on the analysis, STF Energy was able to develop technically optimised solutions in electrical technology, building automation, heating, ventilation, air conditioning, heat recovery, sanitary technology, lighting, emergency energy supply and building physics.

    In the proposal, the investment costs and necessary measures were clearly outlined. Moreover, the STF experts issued the client with a thermal insulation certificate according to DIN 18599.
