DAS ARTMANN was nominated by the City of Vienna as one of 100 showcase projects as part of the “Raus aus Gas” initiative, demonstrating once again what forward-looking renovation of existing buildings can look like.

A Pioneer of Vienna’s Energy Transition in Existing Buildings

The “Raus aus Gas” initiative has a clear goal: the gradual phase-out of fossil fuels in Vienna’s existing building stock. The fact that our historic preservation project at Obere Donaustraße 19 has been highlighted as one of 100 projects confirms our commitment to consistently pursuing sustainable and future-proof solutions, even in complex retrofit projects.

River Water as a Source of Energy

The centerpiece of DAS ARTMANN’s energy concept lies right on its doorstep: the Danube Canal. An innovative water-source heat pump system harnesses the river water as a natural energy source. In winter, it is used to heat the 75 apartments and 4 office spaces; in summer, the same system provides efficient cooling—entirely without fossil fuels. This aquathermal system also supplies hot water year-round.

After use, the extracted water is returned to the Danube Canal via an underground pipeline approximately 100 meters long. This creates a sustainable, local energy cycle that makes optimal use of available resources while protecting the environment.

The system is supplemented by a rooftop photovoltaic system with a capacity of approximately 65 kWp, which further significantly reduces the heat pumps’ energy consumption. Combined with a smart control system for heating, cooling, and ventilation, the result is a holistic energy system that is both environmentally friendly and cost-effective.

Measurable Impact

The results speak for themselves: Thanks to the comprehensive revitalization and the innovative energy concept, CO₂ emissions were reduced by approximately 58% compared to demolition and new construction. At the same time, heating demand has decreased by approximately 35.7 kWh/m²a compared to the unrenovated building—a significant contribution to decarbonization in an urban context.

Preserving Historic Sites Meets Climate Protection

It is particularly noteworthy that this transformation was carried out in a historic building dating from 1866. While complying with all regulations, the historic exposed-brick facade was preserved, and the building was brought up to modern technical standards.

Triple-glazed windows, thermally optimized exterior walls in the annexes, and decentralized ceramic heat exchangers in the apartments further ensure a high level of living comfort and energy efficiency.

Our Mission

Since the project began, our goal has been not only to create high-quality living spaces but also to set new standards for sustainable project development in existing buildings. Being recognized as a showcase project by the City of Vienna—along with the upcoming “klimaaktiv” Gold certification—is a confirmation for us that we are on the right track.

DAS ARTMANN demonstrates how historic architecture, modern technology, and sustainable energy supply can be combined into a comprehensive, future-oriented concept.

We are pleased to introduce a new project to our portfolio today: the
PARKRING TOWER—an exclusive residential development at one of Vienna’s most prestigious addresses.
Located directly at Parkring 12, in the same building that houses the Hotel Parkring
, an extraordinary residential complex is taking shape here in Vienna’s first district
.

Urban living at its finest: Just a few minutes’ walk from Stephansplatz, the “
” Wollzeile, and Stadtpark, the PARKRING TOWER combines vibrant city life
with a peaceful, green setting.
Future residents will benefit from the ideal combination of a central location,
excellent transportation links, and the exclusive atmosphere of the First District.

You can get a first look at the current status of the construction site in our “Coming Soon” video on Instagram at

From an office to a living space with character

The second floor of the building, which previously served as office space, is currently being converted into nine
high-end condominiums with living areas ranging from 55 to 129 m².
What used to be the office of CUUBUUS architects & developers is now being transformed into a space for
modern, stylish living. Each unit features well-thought-out floor plans, generous
window facades, and a bright, open feel.

Construction Progress: All Signs Point to a New Beginning

Now that the gutting work has been completed, the entire floor is currently in the structural shell stage at
.
All existing interior walls and office structures have been removed, laying the groundwork for the
new floor plan.
Work is currently in full swing—from the technical infrastructure to the installation
of new systems and the preparation of future space concepts.
Every day, the construction site is a hive of activity: tradespeople, site managers, and
architects are working together to transform the former office spaces into a place with
an extraordinary residential character. See for yourself—here are some recent impressions
straight from the construction site:

Exclusive living comfort at the highest level

The planned condominiums combine aesthetic design with functional elegance.
Premium materials, oak parquet flooring, in-floor heating, and contemporary bathrooms featuring high-quality
ceramic fixtures create an atmosphere of tranquility and quality.
A concierge service, elevators, and an underground parking garage underscore the premium nature
of this project.
Some units also feature private outdoor spaces with views of the city park—a
rare luxury right in the heart of downtown Vienna.

Life on Parkring: Where Culture, Cuisine, and Comfort Meet

Whether it’s a stroll through the city park, breakfast at the café on the ground floor, or a
shopping spree through the boutiques on Graben and Kohlmarkt—everything here is just a few
steps away.
The central location offers ideal conditions for professionals and cosmopolitans who appreciate
urban life without wanting to sacrifice peace and comfort.
Numerous cultural institutions, such as the Vienna State Opera, the Albertina, the Hofburg, and the
Burgtheater, are just a few minutes away, making the First District a
unique place to live.

A Project That Brings People Together

The PARKRING TOWER embodies Viennese living culture in a contemporary form—for people who are looking for something special
and appreciate quality at every level.
From a former office floor to a place of connection, tranquility, and inspiration: This
project demonstrates how urban architecture, functionality, and quality of life can be perfectly combined
.
