Taking into account listed buildings, economic and design requirements such as preservation of individual details, renovation during ongoing operation, gutting with new extension, etc., we develop targeted renovation concepts for the facade on the basis of precise measurements as well as material, strength and load-bearing capacity analyses.

• Energy requirements?
• Weighing up the priorities in the “magic triangle” of quality, costs and duration
• Definition of an objective as a benchmark for all subsequent planning phases
• Development of the evaluation criteria as expert assessors in architectural competitions

• The physics of the building and acoustic requirements are taken into consideration
• Fire protection and smoke extraction are taken into consideration,
• Cleaning and maintenance plan, access at heights
• Outlining solutions, costs and timings
• Inclusion of existing solutions to clarify the design
• Support during the initial sampling
• Documentation in report form
• Ongoing updating or further development of the design

• Integration of fire safety and smoke extraction plans
• Security requirements are taken into consideration
• Collaboration on the overall design so that it can be approved
• Joint design, joint width and depth in accordance with the building movements identified and relevant tolerances
• Documentation in report form
• Ongoing updating and further development of the design, cost estimate and construction scheduling
• Support in the planning and implementation of 1:1 facade samples to ensure that the design is progressing as intended, e.g. in design-and-build processes

• Planning on the basis of static pre-dimensioning for the relevant facade components – glass, profiles, fixings
• Advanced planning for the building physics and acoustics
• The specified security and fire safety requirements are taken into consideration
• Planning and integration of control and operating components
• Updating costs and the construction schedule
• Agreed plan for the materials
• Glass specifications

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.

• 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.

• Profile and glass structural specifications
• Calculation and analysis of finite elements
• Project structural analysis as documentation for the relevant auditors
• Structural evidence depending on the region based on EN standards or Eurocode, British Standards or American Standards.
