Networking Event: Comparing the SOBON Study | March 2026

Renewal of the “Regulated by RICS” Quality Mark I October 2025
In 2025, ARELIO GmbH once again received the international “Regulated by RICS” quality mark. Yes, it is routine — many confirmations of “no issues identified” and “the figures are in order.” Nevertheless, it serves as an important reminder: compliance may look good on panels and in blog posts, but what truly matters is consistent adherence in everyday practice.
Together, turning “Yes, but…” into “Absolutely” I September 2024
On 12 September 2024, the RICS Regional Group Munich, together with Accom Immobilien GmbH, hosted an event on the topic of “Building within Existing Structures.” Sarah Dungs and Diana Anastasija Radke represented the Association for Building within Existing Structures (BiB) e.

Contribution in the ZIA Annual Report I 2019
The establishment of a digital infrastructure is essential to ensuring long‑term competitiveness.
For Big Data to be effective, robust data foundations must first be established.
The new HAUFE Digital Guide Real Estate is here! 2019
“Who really still knows their way around today? Processes within companies are becoming increasingly complex, and business models are multiplying.
So when once seemingly constant opportunities to optimize returns in the real estate industry fundamentally change, when established ways of generating income no longer work…”
Awareness of Data Standards Is Increasing I 2019
gif recently published its standard for data rooms. However, such a standard is only half the equation. Only if as many stakeholders in the industry as possible adopt it, will the management of real estate‑related documents become significantly simpler and faster than it is today.
New gif guideline: “Standard for the Implementation of a Real Estate Data Room and Document Management System 2.0”
“Data standards exist, but are often not implemented” – as early as 2015, gif published a model index for real estate data rooms. After several months of work, the new gif guideline, including success stories on the implementation and exchange of real estate data rooms, was presented on May 21, 2019 in Frankfurt am Main.
Dominik Brunner in an Interview with Immobilien Zeitung
“Data standards exist, but are often not implemented” – Dominik Brunner, Managing Partner at the IT service provider ARELIO, believes that the real estate industry itself bears the primary responsibility for actually applying existing standards.
Immobilien Zeitung: Mr. Brunner, why is the real estate industry making such slow progress in implementing digitalization?
Dominik Brunner: The industry is currently doing very well. As long as acute workflow issues can simply be resolved by adding more…
MIPIM PropTech Europe – Magic Numbers and More I 2018
33 is not only the international dialing code for France – it is also the repeatedly cited average age of visitors to MIPIM PropTech Europe, or – proudly announced time and again by founders – the average age of the respective proptech company (that can hardly be a coincidence).
And while we’re on the subject of numbers: at MIPIM, a rather relaxed approach to attendance figures has almost become a tradition. 1,500 visitors are announced – on‑site estimates based purely on observation tend to range somewhere between 500 and…
The New Haufe Real Estate Software Guide I 2018
Multidimensional directory structures for real estate data rooms may not sound as exciting as self‑flying drones. What they are, why real estate professionals need them, and why they will soon become standard practice is explained in the specialist article by gif e.V. in the current Haufe Real Estate Software Guide.
Regatta – Business Cup I 2018
Team spirit, tactics, and technology. Three elements that – among others – are just as essential in regatta sailing as they are in project work.
That is why we were delighted to support the Coriolis Sailing Team at the Business Cup 2018 in Croatia in May. Finishing third in the strongest class (Bavaria 41S with spinnaker) was a remarkable achievement! The fun factor is undeniable – but seeing how people, equipment, and machines perform under pressure is what truly makes the experience…
Oxford Real Estate Conference I 2018
An opportunity to think outside the box? The Oxford Real Estate Conference 2018 was held under the theme “Innovation in the Real Estate Industry.” While this may no longer be an entirely novel conference topic in this country, the format has consistently delivered interesting – and previously unknown (!) – insights in the past, making it well worth attending once again.
Commentary in Immobilien Zeitung: “Digitalization” Is What “Sustainability” Used to Be I 2017
Are you already sorting through your Expo appointments? When it comes to events featuring the words “tech” or “digitalization” in their titles, you can choose from 24 options. By comparison, there were only eleven such events in 2016, and just three in 2014. A familiar pattern can be observed here: the same once happened with the term “sustainability.” A well‑established idea was followed by years of hype – and then by consolidation. The current situation follows a similar classic pattern…
DCF – A Brief Introduction to Real Estate as an Investment Asset I 2017
Article published on the blog of the Real Estate Lounge.
In times of low interest rates, real estate presents itself as an attractive investment option alongside equities and funds. It promises relatively predictable returns and is more directly controllable than financial transactions on the stock market.
While determining returns may sound straightforward, it is often difficult in practice. This is because the calculation involves a wide range of factors, some of which interact in complex ways.
ARELIO DCF Is Live! 2017
After several successful test rounds, the time has come: ARELIO DCF is live and available to everyone upon registration. Simple, transparent, and fast – DCF models for buyers, sellers, brokers, financiers, or project developers can be created almost instantly.
The guiding principle “more than a beer mat – less than a corporate ERP system” is explained and brought to life with ARELIO DCF.
What the Tower of Babel Has to Do with IT for the Real Estate Industry I 2017
This topic is explored in the Haufe Real Estate Software Guide 2017. As is well known, the construction of the Tower of Babel failed due to the multitude of languages spoken. The real estate industry faces a similar challenge today – it needs a common language.
Standardization in data exchange can provide the foundation for a shared digital infrastructure.
Read the article here, which I co‑authored together with Dr. Stephan Seilheimer.
The Success Stories of Data Standards by the gif Society for Research in Real Estate Economics (gif Gesellschaft für Immobilienwirtschaftliche Forschung e.V.) I 2016
A key foundation for efficient real estate IT – and also for today’s much‑praised proptech solutions – is a standardized data infrastructure to which new tools can easily and consistently connect. The gif Society for Research in Real Estate Economics (gif e.V.) has been seriously addressing this topic within its Real Estate IT – Data Management Competence Group since 2010 – and with great success (and not only since “digitalization” became a buzzword).
Unlocking More Value from My Real Estate Assets? With a Target Operating Model and the Right IT Approach! 2015
In recent years, a significant portion of real estate asset management services has been outsourced to external partners. Historically grown and highly fragmented service structures of institutional investors have been streamlined and largely consolidated with major external providers. This trend is set to continue, leading to the outsourcing of additional middle‑office functions.
