  • Market requirements

    Energy systems: market requirements and trends

    In Germany and many other countries, promoting renewable energies has become an integral part of politics nowadays. Be it for planning new quarters, buildings or industrial plants: the limited availability of fossil resources and the need for better environmental protection causes the number of regulations prescribing an efficient use of energy to grow constantly. When done wisely by making smart use of new technologies, you can generate economic benefits through energy saving measures and through the integration of renewable energies – no big deal with system simulation. The following examples give an overview of the requirements for manufacturers, operators and planners of innovative energy systems:

    • Ensure operational safety and availability
    • Perform torsional vibration analyses with respect to malfunctions and disastrous situations as well as shock related and nonlinear load effects for certification and approval procedures
    • Optimize thermal fluidic processes and circuits as well as heat transfer processes
    • Integrate renewable energies into local power grids and design the optimum energy storage

    • Reduce energy demand for heating and cooling systems as well as air conditioning in buildings and plants
    • Comply with regulations for environmental protection and energy efficiency
    • Secure market shares through lower operating costs
    • Integrate waste heat recovery
    • Separate air and heat flows for higher energy efficiency
    • Determine efficiency levels (= return on investment) of innovative technologies before the start of a concrete project

    • Plan efficient systems for heat and power supply
    • Design coherent integrated energy concepts for big building complexes
    • Integrate renewable energies into existing electricity, heating and refrigeration systems for new and transformation projects

    Developing safe and available energy technologies

    The high energy density in power plants, transmission paths and storages must be constantly available while remaining safe for man and the environment. From various projects, we know the complex requirements with respect to energy efficiency, the integration of renewable energies and safety. Our simulation solutions offer you a solid foundation in order to meet all of these requirements – fast, safely and efficiently. We are happy to discuss the details with you.
