Tenders Are Invited For New Construction Of The Bertolt Brecht School In Darmstadt - Electro

New Construction Of The Bertolt Brecht School In Darmstadt - Electro. The Bertoltbrecht School In Darmstadt Is To Be A Modern, Innovative, Energy-Optimized Building. For A Technically Flawless And Safe Operation, It Is Absolutely Necessary To Equip The Building With The Most Modern Electrotechnical Systems. Object Of Performance: Planning Includes: The Complete Emergency Lighting System Including The Central Battery System, The Entire Cabling, Some In Functional Integrity F30, And All Emergency Lights New Medium-Voltage Switchgear In The Form Of A 20Kv/400V Compact Station With A Transformer. This Transformer Station Also Supplies: Morgenstern School, Adelung School And Roller Sports Hall Central Battery System To Supply And Ensure Compliance With All Requirements According To Din En 1838 And Bgr 216 For The Necessary And Required Safety Lighting The Central Battery System Including The Batteries Is Located In Its Own Operating Room In The Basement Of The Main Building The Bbs Darmstadt Area Will Receive A New Nshv As The Main Distribution Point In The New Building In The Basement For An Emergency Power Supply Via A Portable Backup Generator, An Additional Emergency Power Supply Is Carried Out Using Mechanical And Electrical Controls. All Outlets Are Equipped With Nh Switch-Disconnectors Using Withdrawable Technology A Multi-Measuring Device Is Installed In The Distributor Feed For Metrological Recording. All Measured Values ​​Are Managed Via A Bus Interface And Can Be Transferred To The Higher-Level Building Management System. The Multimeter Has An Electronic Meter Display To Display U/I/F/Cosw/P/S/Q/W, Grid Analysis Acquisition And Internal Memory Cables And Lines For The General Power Supply, Emergency Lighting And Telecommunications And Information Technology Systems Are Each Routed In Separate Cable Routes The Building Receives A Potential/Protective Equipotential Bonding In Accordance With Parts 200, 410 And 540 Of Din Vde 0100. All Installation Devices Are Labeled Using An Integrated Labeling Field According To Their Assignment. All Rooms Are Equipped With Lighting Fixtures That Are Tailored To The Use Of The Space. The Lighting Is Designed According To The Guidelines Of Asr 7/3, Amerv, Din 5035, En 1883 And Din En 12464. If Technically Not Possible, All Lights Are Equipped With An Electronic Ballast (Evg). Some Of The Lights Are Dimmable To Adapt The Lighting To The Use Of The Room And For Daylight-Dependent Control. All Dimmable Lights Have A Dali Electronic Ballast And Are Controlled By The Building System Technology Via A Dali Gateway. All Lights Are Equipped With Led Bulbs. Three Lighting Levels Are Planned (0.50 And 200 Lux), Which Are Implemented Depending On The Time Of Day And Presence: During Operating Times Without Presence Detection: 50 Lux During Operating Times With Presence Detection: 200 Lux Outside Operating Times Off: 0 Lux Outside Operating Hours With Presence Detection: 200 Lux The Control Is Implemented Using A Knx Timer, Knx Presence Detectors In The Relevant Corridor Sections, Knxdaligateways And Lights With Dali Controllable Electronic Ballasts. All Rooms That Are Only Used For A Short Time, If Technically And Economically Sensible, Are Equipped With Conventional Presence Detectors Toilet Rooms Have Lights With Integrated Hf Presence Detection Sensors The Lighting In Classrooms Is Switched On With Presence Detectors, Motion And Daylight-Dependent Constant Light Control And In Parallel Manually The Room And Blackboard Lighting Are Always Switched On Separately By Hand. Switching Off Is Done Manually Or After 10 Minutes Without Presence In The Room. If The Proportion Of Daylight Is Too High, Constant Light Control Automatically Dims To The Target Level The Required Safety Lighting Is Provided By Led Lights Powered By A Central Battery
