GSG Berlin’s dedication to advancing building design and technology was recognized with the WiredScore Certificate of Excellence for Future-Readiness during the Insights 2025: Building for People event.
This recognition highlights the company’s leadership in making its buildings not just functional and sustainable but also incredibly well-connected, prepared for the digital demands of tomorrow.
Insights 2025: Building for PeopleAs a member of WiredScore’s 2025 Portfolio cohort, GSG Berlin is committed to ensuring its properties are future-ready. To further enhance these efforts, GSG Berlin has prioritized the adoption of WiredScore’s Mobile assessment across its entire portfolio, ensuring that occupiers benefit from seamless, high-performance mobile connectivity throughout their workspaces. This focus on mobile connectivity ensures that businesses can operate efficiently, even on the go.
We caught up with Justin Lutterbey, Innovation Manager at GSG Berlin, to discuss how they have further elevated their buildings’ mobile experiences by adopting WiredScore Mobile assessment across their portfolio, providing occupiers with seamless, high-performance connectivity.
What sets GSG Berlin apart when delivering the best technology experience to occupiers?
GSG Berlin stands out by constantly evolving and utilizing our own digital infrastructures and engaging in hand-in-hand-planning with our joint venture Campus Hofnetz & Events, the in-house internet service provider for GSG tenants.
Together, we have made WiredScore standards an integral part in our planning and construction processes, so we are able to continuously upgrade our portfolio to meet the highest global standards. This has led us to achieving one of the best performing WiredScore portfolios in Europe, with many buildings earning a perfect score of 100/100 credits, even though these are mostly historic, listed buildings more than 100 years old.
As a result, GSG makes it possible for tenants to work in a highly modern, digital and cost-efficient way l in beautifully historic settings.
How is GSG approaching the mobile experience of occupiers across your entire portfolio?
The first time we wanted to tackle the question of how good the mobile experience on our sites are, we were a bit clueless, or let me say dataless! Mobile connectivity wasn’t really on our agenda, but due to modernizing ways of working, we found it crucial to change that.
WiredScore’s global benchmarking gave us a good sense of direction for where our mobile experience needed to go, as they recognize it as a crucial part of a building’s connectivity. The standards they set helped us form an appropriate basis to make decisions across our properties, but also around mobile.
What motivated you to adopt the WiredScore Mobile Assessment for your portfolio?
Understanding our buildings is key. The more we know about our buildings, the bigger the opportunities are for us to make them a top-notch workplace. And mobile connectivity is becoming a more and more important aspect of that.
While our cable infrastructures and high-speed internet through our own fiber optic network are robust and best-in-class, we recognized the need to enhance the overall mobile connectivity across our portfolio. The WiredScore Mobile Assessment seemed a perfect first dive into the mobile performance of our buildings, showing us what the buildings currently offer and where they need to improve.
How did you find the WiredScore Mobile Assessment and what did you gain from it?
We found the WiredScore Mobile Assessment to be an ideal solution to providing an initial sketch of the mobile reception at our sites. It offered us an immediate opportunity to identify priority areas for deeper analysis and following improvement, not only per building but also by specific sections and areas of each building.
This process proved to be both cost and time-efficient, especially because with this method no one needed to be on-site to measure and generate the needed data, and with some of our sites being over 100,000 m², this is definitely a huge win.
The mobile assessment represented a very valuable starting point for our mobile performance improvement journey, to be followed up with detailed measurements inside each rental unit.
How has understanding the Mobile Assessment of your buildings better equipped you to answer queries from existing or prospective occupiers?
During viewings, potential tenants sometimes pull out their mobile phones as soon as they enter the building to check the reception. So now we are equipped with data-based answers to connectivity-related questions.
Although the overall interest in mobile reception seems moderate, it remains an important topic for us to stay ahead of the market. As mobile performance is likely to become a more pressing issue, especially in newer buildings with energy-saving features like triple-glazed windows, we can effectively address these concerns.A significant advantage is that we can provide specific performance metrics for each of the three main mobile providers in Germany across different areas of our sites.
This also creates transparency and supports tenants to make profound and sustainable decisions.
Has understanding the performance of your portfolio enabled you to make more informed design decisions in the future?
Considering that our portfolio consists of numerous older buildings, we are of course planning and building our projects totally different than the architects and construction companies from the late 1800s and early 1900s.
Therefore, we treat and use the data from these buildings in another way than the data we’re getting out of newer ones. Either way, by analyzing the mobile connectivity data we can identify potential design flaws that may hinder mobile reception and proactively address these issues in future projects.
This insight allows us to integrate connectivity considerations into solution evaluations and design decisions, ensuring that both current and future buildings meet the evolving needs of our occupiers.
