Digitized office building in Berlin

Embedded in a park-like setting, CA Immobilien Anlagen AG (CA Immo) has constructed a new office building in Berlin Kreuzberg. The "grasblau - Official Morning Has Broken Office Building" is ideally prepared for the requirements of tomorrow. The building's concept offers answers to ecological sustainability, attractive working conditions and digitalization issues

CA Immo Deutschland GmbH



Connected Devices

2200 lights, 40 KNX devices


2022 - 2023

Use Cases

Automatic lighting control, area evaluation, energy monitoring


The building, designed by HPP Architects, offers flexible configuration options for individual rental needs on around 13,400 square meters and six floors. Thanks to well-thought-out architecture, grasblau offers optimal usage options.

Green Building

The grassblau is designed as a green building. The focus is, among other things, on environmentally friendly construction, the sustainable and future-proof operation of the building and the health of the users. The aim is to obtain sustainability certification from the German Sustainable Building Council (DGNB German Sustainable Building Council) in “Gold” and certification according to the WELL Core & Shell Standard. In the grassblau, CA Immo is consistently continuing the digitization strategy of its high-quality project developments such as the cube berlin, the Upbeat in Europacity, which was rented exclusively to DKB in 2021, and the ONE office and hotel high-rise in Frankfurt, which was completed in 2022. Like the ONE, the grasblau should receive the WiredScore® certificate for the best connectivity and the SmartScore certificate for the best digital user experience, each in the highest Platinum category.

Digitalization with BlueRange

Digitalization of a building means, for example, that the individual components communicate with each other, can be controlled “intelligently” and can then be operated optimally, efficiently and in a resource-saving manner over the entire life cycle of the building. In the grasblau, BlueRange technology is used for intelligent lighting, lighting control, occupancy measurement and location tracking (POI). At grasblau, networked technology is used to support sustainable building operation through digital sensors – using wireless communication. 2,000 luminaires from XAL and downlights with integrated Vossloh-Schwabe Multisensor XS are in use. These motion sensors work with BlueRange technology and ensure automated lighting control. The general room brightness is also recorded by these sensors. It is possible to intervene and, by integrating the wired standard of the KNX Association - or that of the BACnet Interest Group Europe - into BlueRange, to operate switches manually or to control the light via the grasblau app. The beacons additionally built into the multisensors enable the integration of so-called POIs, including the display of useful user information via the grasblau app or indoor navigation in the building, as well as finding people who have been approved for this purpose. The sensors communicate wirelessly using the built-up BlueRange mesh and pass on data to a gateway, which then forwards this data to a cloud or a central server located in the building. This collected data is used, among other things, to record the space and room utilization in the building - an important basis for coordinating room and workplace bookings using apps and making optimal use and utilization of office space. This also applies to optimized heating, ventilation and cooling depending on the actual occupancy. BlueRange can do even more. It is the digital platform that makes no distinction between wireless digital data and data from the wired KNX network or the BACnet. All data is collected and unified by the BlueRange gateway.

The grassblau building is in the immediate vicinity of the popular office location Potsdamer Platz and in a preferred location on the Landwehr Canal. Despite the urban, inner-city surroundings directly on the “Hallesches Ufer” highway, the location scores with an unusually quiet and green micro-location. The approximately 13,400 square meter building is located in Berlin’s trendy Friedrichshain-Kreuzberg district. Tall trees and a park surround the new building and enable a unique work-life balance.


CA Immo is a real estate group headquartered in Vienna, which has its own branches in six countries in Central Europe. The core business is the leasing, management and development of high-quality office buildings. The group has strong in-house construction expertise and covers the entire value chain in the commercial real estate sector.
