STF EnergySTF Energy

STF Energy stands for customised engineering services in the fields of energy and resource efficiency, technical building services and building physics. We utilise integral, conceptual solutions and actively support our clients during each and every phase of their projects. We develop interdisciplinary engineering solutions tailored to reduce construction costs and operational expense while optimising the efficiency of systems, processes and buildings as a whole.


Energy Management

STF ENERGY plans and develops concepts to increase energy efficiency for companies in all sectors. Moreover, our specialists provide support in the implementation of the concepts.

  • Energy Consultation for Mid-Sized Companies

    SME energy analysis allows companies to save on two fronts: STF's BAFA certified engineers help you to systematically uncover savings potential within your company. Thanks to governmental support, companies with annual energy expenses of over 10,000 euros (net) can save up to 8,000 euros or 80 percent of eligible consultation expenses.

    Our Services:

    • support when applying for grants and subsidies
    • measurement and analysis of energy use
    • evaluation of energy consumption profiles
    • development of energy efficiency measures
    • feasibility calculations for EEG systems
    • lifecycle expense assessment
    • finalised reporting presenting optimisation potential
  • Energy efficiency analysis

    As energy demand increases, energy costs rise constantly. Efficient use of energy is the only way to reduce both consumption and costs. Together with our clients and our partners in research and development, we develop customised and sustainable concepts for energy efficiency. We proceed according to the four following steps:

    1.     Analysis
    As part of a holistic analysis of your locations, we take a close look at areas that could affect your energy consumption. Besides assessing the electrical, heating, cooling and ventilation systems, we conduct an overall energy assessment of your building.


    2.     Concept development
    Based on the analysis, we draw up customised short-, medium- and long-term measures to optimise your location. We place particular emphasis on technical building equipment in order to best exploit the identified cost savings potential.  


    3.     Implementation/support
    Once a concept has been developed, we implement the defined measures and support you in the inception of a customised energy controlling system.


    4.     Monitoring
    In order to guarantee the sustainability of the implemented efficiency measures, we will monitor the degree to which the target is achieved and the effectiveness of the measures on a regular basis.

  • Energy Consultation for Agriculture and Horticulture

    The energy consultation programme of the Federal Agency for Agriculture and Food (BLE) is directed especially at individuals and companies working in agricultural and horticultural fields. STF Energy's consultations systematically identify areas with energy savings potential. Thanks to governmental support, companies can save up to 6,000 euros or 80 percent of their eligible analysis costs.

    Our Services:

    • support when applying for grants and subsidies
    • measurement and analysis of energy use
    • evaluation of energy consumption profiles
    • development of energy efficiency measures
    • feasibility calculations for EEG systems
    • lifecycle expense assessment
    • finalised reporting presenting optimisation potential
  • Municipal Energy Consultation

    Municipal energy consultation offers communities and charitable organisations funding for the development of an energy related renovation concept as well as support in the planning of new, energy-efficient, non-residential community buildings. Funding can mean savings of 80 percent of eligible expenses up to a maximum of 15,000 euros. The restructuring concepts created by STF Energy can be used as a conceptual plan for a complete, one step renovation into a KfW low-energy building or as a renovation roadmap for long term processes.

    Recognising energy savings potential and the optimisation of processes are a major part of being competitive in today's marketplace. There are funding opportunities and subsidies meant to encourage energy-saving technology investments which are directed especially at large companies but also meant for smaller, mid-sized enterprises. These cover not only individual measures but also complex energy efficiency concepts such as the optimisation of technical systems (OTS) including new purchases and acquisitions.
