State Award


State Award

Our engineering firm IPJ is one of the winners of the Austrian State Award for Architecture and Sustainability, which was formally awarded in Innsbruck. The State Award is the highest award of the Republic of Austria for sustainable building.

The jury expressly praised the innovative energy concept for the Montforthaus event building in Feldkirch/Vorarlberg, which we developed for the project. “Comfort ventilation, a heat pump and consistent use of waste heat are building blocks for strong sustainability performance,” stressed the experts, praising the versatile construction as “a house for all occasions”. The architectural association of Hascher Jehle (Berlin) and Mitiska Wäger (Bludenz) is responsible for the architecture of the organically curved, reinforced concrete structure, with a natural stone façade that blends harmoniously into its surroundings on the edge of the old town. The international jury of experts selected five projects from 76 submissions – including Montforthaus – and praised them as “flagship projects for sustainable building”. “We just feel like we won an Oscar,” says Patrick Jung.

Top rank

In the current ranking of the competitionline platform, our firm came second in the energy consultant category. In the building physicist category, we improved by two places and jumped up into the top ten. The portal is an important platform for architectural and engineering competitions. Once a year, a team of German architects, journalists and IT professionals evaluates all the competition results published on, and from this a ranking is created of the firms that have participated in competitions with the greatest success. In the field of energy consultants, the IPJ firm, with its successful contributions from Cologne, Vienna and Hamburg, secured second place right behind the division winner Transsolar Energietechnik GmbH. We would like to thank the architects and all our colleagues in the cooperating engineering firms, and we look forward to further joint competitions.


Ikea: Sustainable path into the future

At the Swedish furniture store IKEA, the subject of “Sustainability” ranks high on the agenda. August 2013, the group had invited 14 external experts from all over the world to a three-day workshop at Copenhagen “  in order to discuss and to develop innovative concepts for “sustainable stores“ there together with the IKEA-internal project managers. As a consulting engineering company, IPJ – represented by Patrick Jung – took part in the IKEA blue cube summit. IPJ Cologne is proud to carry out the BREEAM certification process, building physics and energy concept for the giant new IKEA “More Sustainable Store” in Kaarst, opening October, 12th, 2017.

innovation city ruhr

The Ruhr area city of Bottrop has risen to the challenge to demonstrate – within the scope of the project Innovation City Ruhr – the conversion into a sustainable and environmentally friendly city. The ambitious objective is to cut down to half the energy consumption and the CO2 emissions, to increase the quality of life and to secure the industrial location at the same time. The IPJ firm supports this process together with the partners of the EcoCommercial Building Network through the concept development and planning for two PlusEnergy buildings.

IPJ Vienna office

The Austrian branch of IPJ in Vienna is working with great success projects in the fields of building physics, sustainable construction, daylight analysis and flow simulations. Under the direction of Dr. DI Peter Holzer, our graduate engineers, Kendlbacher, Löschenbrand, Padayhag and Vicente-Inigo are supervising several interesting projects, such as the New Austrian Embassy Bangkok, the plus energy building of Windkraft Simonsfeld and the Vienna Hofburg Refurbishment.

Being a Guest at Bellevue Palace

Some 200 pioneering environmental and nature conservation projects were presented at the fourth “Woche der Umwelt”, on 5 and 6 June 2012 in the castle gardens of Bellevue Palace, the official residence of the German President. One of them is the research project “TEK – Partial  energy coefficients of non-residential buildings”, where IPJ works closely together with the non-profit Institute Wohnen und Umwelt IWU.

An independent jury has selected projects for the event that particularly distinguished themselves in terms of quality, innovation and model character. More than 12,000 visitors informed themselves – both by speaking with the invited exhibitors and in numerous professional forums and discussion groups – about innovative approaches with regard to climate protection.

Detail Green Books: Zero-energy buildings

A recommendation: a book published in June 2011, with the title Zero-energy buildings by Prof. Karsten Voss and Eike Musall. As co-author, Patrick Jung contributed the technical information about the project Kita “Die Sprösslinge”.

UNEP-SBCI Symposium in Leverkusen

At the invitation of Bayer Material Science, Patrick Jung – as a member of the EcoCommercial Building Network – was able to attend the symposium of the United Nations on sustainable buildings. There, on 24/05/2011,uniform methods for the evaluation of climate change policies were discussed, and the necessary conditions for a political paving the way for sustainable buildings were set out.

Award winning – DEG Bank, Cologne

Top marks for sustainability to DEG Bank for its new office building in Cologne. At the sustainability convention CONSENSE in Stuttgart, the new building, energy-optimized by Büro IPJ, has now been awarded the Gold Seal of the dgnb (Deutsche Gesellschaft für nachhaltiges Bauen e.V.) Congratulations to the client and JSK Architekten – and we are pleased about our joint success.

Kita for the Bayer CropScience, Monheim

Within the scope of the Berliner Energietage 2009, the Kita of the Bayer CropScience in Monheim was awarded the EnOB Prize of the German ministry of economics. The reason: The company kindergarten is being operated as the first CO2-neutral building of its kind. Being responsible for the energy concept we are happy for and together with the client, Bayer Real Estate, and the planners, tr.architekten.
The EU Commission, too, bestowed an award: the Green Building Award 2011. The Bund deutscher Architekten BDA NRW praised the performance of tr. achitekten and the successful integration of the high energy standard and rewarded the effort with its award named “Auszeichnung guter Bauten 2010”.

Organic Farm

IPJ would like to warmly congratulate the Achleitner family and its construction partners on the awarding of the Solarpreises 2005 by EUROSOLAR. The new building is an exemplary combination of bioclimatic, solar and ecologically optimized architecture in a modern and discreet design. We are pleased to have contributed to the energy strategy for this beautiful building.


The operations building Biotope in Weidling has been nominated for the Austrian National Award for Architecture and Sustainability 2006. We were able to assist Büro Reinberg with a variety of simulation calculations.

House of Research

The House of Research in Vienna has won the special prize for sustainability in office buildings. This award is a special prize of ÖSTERREICHISCHEN BAUPREIS 2006. For the House of Research, we were responsible for the climate and energy concept, from conceptual design to commissioning.  The monitoring is supported by the Department of Building and Environment, Danube University.

Energy Globe Award

The “Energy Globe Award” is the “Academy Award for Sustainability”. National and international level projects that contribute to the especially efficient use of energy are distinguished with this prize.  Among the prizewinners of 2007, that are announced on 26th May, 2008 within the scope of a big gala at the European Parliament in Brussels, there are two projects where IPJ have consulted and have provided support:
The Award for the best Austrian project went to Fronius International GmbH; the national “Energy Globe Award” for Turkey went to the building by Dr. Robert Murjahn Institute (RMI) in Gebze near Istanbul. As one of the first commercial buildings throughout the Middle East, the RMI utilizes geothermal energy for heating and cooling and is also characterized by a high level of thermal insulation. IPJ warmly congratulates all the prize winners.
