Sound facade decisions start with a clear understanding of the project’s starting point.

• Priedemann organises the available project information, design intent, use, and facade-related technical and external requirements.
• Together with the project participants, objectives, priorities, constraints and unresolved questions are made visible.
• This creates a reliable basis for the next design steps and for decisions before the facade concept is developed in greater detail.
• Priedemann identifies and structures the project information, requirements, objectives and constraints relevant to facade planning.
• These may include design intent, use, technical and energy-related requirements, local conditions, and quality, cost and programme objectives.

Early facade design begins once the strategic objectives and principal requirements of a project are sufficiently understood for possible directions to be developed.

• Priedemann translates this basis into options for design, materials and construction, considered alongside technical requirements and project-specific constraints.
• The comparison makes differences and trade-offs visible, and a preferred direction is developed further.
• The purpose is not to complete the technical detailing, but to establish a traceable design basis for subsequent development.
• The criteria, sketches and documentation included depend on the project and agreed appointment.

Facade design for statutory approval develops an existing facade concept for the project’s approval and coordination context.

• Priedemann brings together available design information, technical requirements, materials, facade types and interfaces.
• Depending on the project, fire, safety, building-physics and acoustic requirements are also considered.
• The result is a clear facade basis for coordination with the relevant disciplines and for subsequent design.

Facade specifications and tender documentation translate developed facade design into clear technical requirements for tendering and bid comparison.

• Priedemann structures information on construction, materials, details, interfaces and quality criteria and brings the relevant design documents together.
• Depending on the project, this can include technical preliminaries, specifications, quantity information or trade boundaries.
• The scope and function of the documents depend on the procurement and responsibility model.

Thermal building physics connects the facade build-up with the building’s energy and building-physics requirements.

• Priedemann investigates thermal protection, glazing, solar control, insulation, thermal bridges and condensation risk.
• Relevant performance values and material build-ups are determined from local and project-specific requirements.
• Where commissioned, values from the facade and building services also contribute to the overall energy balance of the building.
• Priedemann assesses the thermal performance of facades and develops suitable component and layer build-ups.
• This can include calculating U-values and g-values, insulation thicknesses, isotherms, two- or three-dimensional thermal bridges, surface temperatures and condensation risk.

Facades need to remain cleanable, maintainable and repairable throughout their service life.

• That is why maintenance logistics and safe access belong in the design from the start.
• Priedemann considers not only cleaning and maintenance equipment, but also the facade design itself, moving or electrical components and the future replacement of glazing.
• This helps prepare operation and maintenance in a practical way over the life of the facade.
• Priedemann considers maintenance, cleaning and facade access during design.
• Moving and electrical components, glazing, cleaning methods, access routes, fall protection, walkways and building maintenance units are coordinated with use, safety and construction interfaces.
• Depending on the appointment, the work produces maintenance and cleaning concepts, access strategies and technical requirements for subsequent design.
