13 People, cost, time The key factors for renovating/upgrading

14 People, cost, time The key factors for renovating/upgrading 1 Meet deadlines 2 Little / No impact on users 3 Occupants can stay 4 Noise reduction Quelle:

15 Requirements during and after building upgrade No / little impact on occupants During construction phase Occupants can stay Noise reduction Meet deadlines

16 Requirements during and after building upgrade Finished Building Energy savings Improved Building Appearance Higher level of Functions comfort No / little impact on occupants During construction phase Occupants can stay Noise reduction Meet deadlines

17 Solutions for renovation / building upgrade

18 5 modules for flexibility, efficiency and design Insulation Sun-shading Automation Ventilation ProSol TF

19 Schüco ERC 50: The complete building upgrade system Building upgrade during occupancy Second skin solution Complete installation and wiring from the outside Insulation at EnEV and Passivhouse level (certified) Reduction of fixing points thanks to floor to floor span of support structure Very high level of prefabrication

20 Schüco ERC 50: Installation principle

21 Schüco ERC 50: vertical section Integrated decentralised ventilation device including heat recovery Integrated hidden sunshading Integrated smart opening element Profile integrated cabeling solution

22 Intelligent Building Automation Current situation Schüco solution Buildings of the 60 s and 70 s: no suspended ceilings low level of ducting, cabeling, etc. no automation Intelligent building upgrade combining insulation, automation and a wireless control system
