cube berlin

The cube’s design innovation is evidenced by the globally recognized WiredScore certification in platinum. The certificate confirms the building's "best in class" standard in digital connectivity combined with smart technologies. Kieback&Peter's intelligent, future-proof hardware and software solutions for end-to-end networked building automation made a decisive contribution to this achievement.

The spectacular glass cube, completed in February 2020, was designed as a completely new type of building. On board: a team of specialists from Kieback&Peter's Berlin/Brandenburg branch. The objective: a smart commercial building that enables the most efficient management and the best possible user comfort through a combination of digital building automation and artificial intelligence (AI). It accomplishes this by continuously changing internal conditions such as tenant structure, room and space utilization, and external factors such as temperature and climate. This is how the property becomes truly "smart": through complete digitization and networking, the self-learning system constantly analyzes and interprets building technology and user data. The cube "recognizes" the needs of its users to continually optimize its operation. In concrete terms, this means: sustainably reduced costs compared to similar buildings — especially in terms of energy consumption, maintenance and personnel — while simultaneously providing the highest level of comfort.

To achieve this, the Kieback&Peter team installed 3,750 sensors and actuators throughout the building (temperature and CO2 sensors, heating valves, ventilation flap) and physically connected them to DDC controllers responsible for open- and closed-loop control tasks. The unique challenge here: integrating all trades and various network protocols into a uniform interface with the aim of networking all physical and digital data points, which will then be transferred to the central control unit. This allows for smooth interaction of the automation solution with the building management level.

For the 950 system-integrated sun protection blinds, a thermo-automatic system regulates the light and heat input by means of the slat angle according to the sun’s position. The automatic system has been optimally adapted by Kieback&Peter according to the functions of the combined heating/cooling ceilings across the cube’s ten floors. This automation prevents overheating in the summer and the heating system can be relieved in winter by solar gains. The result: minimized energy use and optimized user comfort.
In addition, the building’s solar shading is automatically raised when safety functions such as fire alarms or storms are triggered.

To ensure the desired temperature always prevails in each office and rental space, the room temperature is recorded via wireless room control units. Depending on the measured value from the room temperature sensor and the setpoint on the controller, the 6-way valves in the heating/cooling ceiling systems are automatically adjusted to meet the individual heating or cooling requirements. The 50 valves per floor are controlled via the BACnet MS/TP network protocol.
