Sustainable by design

The conversion of the historic Gasometer into an event location preserved its industrial aesthetics. The approximately 1,100 m² event space has various conference, exhibition, and catering areas, as well as a multifunctional auditorium that can accommodate up to 2,200 guests. A special feature is the Sky Lounge, whose rooftop terrace is 66 meters in height.

 

Thanks to its complex lighting concept, the Gasometer meets standards required by TV studios and professional production facilities. “The architecturally appealing implementation of mixed lighting suitable for television is associated with corresponding requirements for lighting quality and color rendering”, explains Claas Ernst, Managing Director of VisionTwo, which is responsible for the lighting installation together with the Theapro planning office and the system integrator PIK.

 

 

Multifunctional LED luminaires fitted with RGBCwWw LEDs were installed in order to achieve a lighting system ideally suited for film and TV productions that provides perfect dimming characteristics, excellent color rendering values (CRI), and absolutely no flicker. These are controlled by the ETC Paradigm architectural light processor.

 

The Gasometer features LED luminaires from the Sirius series by the British manufacturer GDS Pioneering Light, which enable variable color temperature from 2700 K to 5000 K, as well as full RGB color mixing. The high-quality LED luminaires not only provide functional light, but they also accentuate the illumination of the columns with color that highlights the architectural character of this historic industrial monument. Over 850 luminaires have been installed, which contribute to the Gasometer’s building efficiency thanks to its energy-saving, centrally positioned LED driver systems. The energy consumption of the Forum’s hall lighting is 210 W in standby mode. “At full load, consumption is over 10,000 watts”, says Claas Ernst.

 

 

At the heart of this sustainable architectural lighting system is the combination of energy-saving LED technology along with the DriveHub system in conjunction with the IPM² data protocol. “This bidirectional control protocol not only enables the power and data supply to be transmitted via existing cabling, it can also transmit multi-channel DMX information in conjunction with power and system data”, explains the VisionTwo Managing Director, which means that additional control cables, such as DMX, no longer need to be laid.

 

In addition to the actual supply voltage, the IPM² system can be used to transmit multichannel control information and system data via a single two-wire network over a cable length of more than one hundred meters without loss. When controlling complex lighting systems, this makes it possible to reduce the voltage peaks when switching on and keep the noload power extremely low. The high-performance power supply units have an efficiency of over 97 percent and a power factor of 0.99, which is 0.6 for conventional LEDs and drivers. “Thanks to the increase in efficiency of over 30 percent, 17.3 tons CO₂ can be saved across the entire installation”, concludes Claas Ernst.
