This is done on the basis of the existing planning, but we also look at implementation planning and detailed planning. We advise on the selection of materials and designs, cost estimates, the selection of suitable suppliers and subcontractors and the development of a technically viable solution.

• Depending on the complexity, we design and plan new facade details to consolidate the technical solution
• Support in the selection of materials and appropriate specialist companies
• Together with the contractors, we develop suitable strategies for procurement, production and assembly
• We offer the development of alternative proposals to benefit the overall project

At the same time, we improve the predictability of the overall project and save time in planning and implementation.

• Adaptation and optimization of facade systems and solutions for a specific project, taking into account functionality, sustainability and costs
• Adaptation and optimization of production procedures, assembly, logistics, installation and fitting

• Operational management, cost and budget audits
• Assessment of technical amendment suggested by the contracting parties, assessment of proposed modifications
• Evaluation of implementation alternatives to the approved diagrams (IFC Issued for Construction Drawings)
• Definition of the main strategic objectives as the basis for a coordinated facade design

• Overall energy performance: We determine the necessary values from building services and the facade to work out the overall energy performance of the building. An important component, especially in residential buildings, is the calculation of the transmission heat loss of the entire exterior of the building.
• Isothermal profile and thermal bridges: We analyse the isothermal profile within the planned or implemented construction, calculate 2 or 3 dimensional thermal bridges and give recommendations to avoid condensation forming
• Component construction with layer construction: Depending on the commission, we draw up a catalogue for the entire building or selected components, which shows the scale of each individual component in its layer structure and specifies the material qualities in order to give those involved in planning certainty about the structural-physical qualities of the planned construction.
• Advice throughout every phase: This is the basis on which we advise architects and builders, general contractors and facade manufacturers, whom we assist in all planning and implementation phases.

• Ambient noise level: We determine the ambient noise level and reverberation times in the room and give recommendations on sound absorption and the distribution of sound-absorbing elements and surfaces.
• Preparation of sound- and noise protection reports: We prepare sound and noise protection reports as part of the approval process.
• Evaluation of internal emissions: We evaluate the emissions of technical installations and give recommendations for compliance with the prescribed noise level values.
• Sound pressure: We define the structural conditions for the maximum permissible sound pressure level in rooms where protection is required.
• Sound absorption: We calculate the sound-absorption surfaces required and propose suitable sound-absorbing materials and surfaces as well as their positioning within the framework of a spatial concept.
  Improving the intelligibility of speech: We develop ways to make speech intelligible and to avoid disturbing echoes in the room.
• Improving the intelligibility of speech: We develop ways to make speech intelligible and to avoid disturbing echoes in the room.

To this end, particularly critical rooms in a building are identified and analysed so that recommendations can be made for further specific planning. When we need to analyze particularly complex systems or processes, we use a range of 3-dimensional flow simulations (CFD Computational Fluid Dynamics). For this purpose, we convert the given three-dimensional building structure into CFD-readable data sets and enter the energetic, building physics and weather data into the program. For example, statements on flow velocities, temperature distributions in the room air and on surfaces can be determined.

We also use CFD programs for the verification of smoke extraction scenarios as well as necessary or planned smoke extraction and post-flow cross-sections. Cross-sections or the number of conventionally determined smoke extraction openings can thus be optimised and often reduced.

For completed projects or ongoing projects – depending on local regulations and the determination of specific building data – we can issue energy efficiency certificates that illustrate the energy consumption of the building as a whole, i.e. in the interaction of building services, facade and use.

• Facade surfaces are often larger than roof surfaces: We can harness the potential of solar energy using suitable systems available on the market.
• While the residential sector mainly needs heating energy, the commercial sector mainly needs cooling energy and industry needs energy for processing.
• The highest demand for cooling occurs, when solar radiation is at its highest. With solar cooling systems we can use this inexhaustible source of energy, save fossil fuels, reduce operating costs and increase efficiency.
• We determine the energy demand, evaluate the potential on the basis of local weather data, the building location and orientation and, together with the specialists involved, develop concepts and solutions for energy generation integrated into the facade.

• We provide information on details that would pose special challenges during implementation or could not be built, e.g. if tested systems or approved products are not applicable, or connections would be so delicate that they could not absorb the loads.
• So that we can react flexibly to the different system environments, we are equipped with the current programs such as Rhino, Grasshopper, Archicad, Revit, AutoCad, Athena or Solid Works and are familiar with many other programs.

Before we enter a BIM environment, we agree the formats and communication standards for the exchange of data with the parties involved. These standards are specified, tested and confirmed during a kick-off meeting. In this way we ensure that all of the information can be incorporated in the main model right from the start. We know that starting a BIM project without these communication standards involves a considerable risk.

These data sets can be transferred to CNC data (Computer Numeric Control) for production. Parametric planning is an efficient and reliable tool for consistent planning and accuracy, especially for complex facade geometries – from design to manufacture and installation. Our parametric data models provide us with a reliable basis for tendering, awarding and implementation.

Priedemann plans all types of media facades and integrates them into the overall design. It is our aim that the media facade is part of the whole, including operation and maintenance, and is not reduced to the level of an appendage or a technical gimmick. For example, we develop concepts in which the energy needed to operate is generated by the facade itself. We take care of the necessary planning and performance data and create a feasible facade design. In the Facade-Lab area we develop transparent media facades together with industrial partners from the glass industry.

• Glass: Glass can be damaged, replacing glass must be possible at any point with reasonable effort. Today, individual panes weigh several hundred kilos, floor-to-ceiling triple glazing weighs up to one ton and more. We plan the right solutions for this.

• Cleaning: Glass cleaning and the cleaning of horizontal surfaces are part of regular operating expenses. We provide simple, secure access with as little technical effort as possible. We make cleaning recommendations and create complete cleaning plans right up to the choice of cleaning agents and necessary intervals with which cleaning can be carried out most effectively.

• Facade development: We plan all facilities for the development of the facade areas, determine the loads of fall protection systems, walkways and access systems and consider the points of contact and passage through the facade to the building shell during planning.
