New Construction & Renovation Consulting

We accompany your project from the initial idea to ongoing operation and see ourselves as mediators between research and practice as well as between clients and planners. We assess the client's objectives concerning technical and economic feasibility and formulate them clearly and verifiably for the further planning process. We ensure their adherence during planning, implementation and operation.

  • Feasibility Studies
    The feasibility studies show how sustainability, quality, comfort and life cycle cost objectives can best be achieved.

  • Definition of Objectives for Sustainable and Energy-Efficient Buildings
    If energy efficiency and renewable energy sources are taken into account early enough, costs can be saved during planning and operation.

  • Electromobility
    We advise property managers, property developers and real estate developers on the development and implementation of solutions for the required e-charging infrastructure in new buildings as well as on the retrofitting of charging stations in existing buildings.

  • Life Cycle Costs
    On the basis of trustworthy decision bases, the client can make life cycle-oriented decisions.

  • Dynamic Building and System Simulation
    Use of modern planning tools to develop sustainable, energy-efficient energy concepts and detailed solutions.

  • Quality Assurance in Building Services Planning
    Implementation of an external quality assurance for the client during the entire planning process for the building services planning.

  • Monitoring Concepts
    Only measured values provide a reliable basis for energy-efficient operation! The basis for this is already laid in the planning stage.

  • Building Certification
    Sustainability certificates show the client's commitment and contribute to quality assurance.
  • Technical Monitoring - Quality Assurance During Commissioning
    Anyone who wants to achieve planned efficiency levels in operation must focus on the commissioning process.

  • Operating Condition Analysis
    Evaluation of heating, cooling and ventilation design to avoid oversizing. Identification of potential partial load behaviour, identification of inefficient operating states, basis for developing an efficient control concept.
