Potenzialstudie für RENVELOPE-Fassadenlösungen in Österreich

© AEE INTEC, Tobias Weiss

Im Rahmen des Leitprojekts RENVELOPE hat das IIBW eine Studie zum Replikationspotenzial der RENVELOPE-Fassadenlösung für den österreichischen Gebäudebestand gemacht. Bei RENVELOPE-Fassadenlösungen handelt es sich um serielle Sanierungen der Gebäudehülle, wobei die Fassadenmodule Elemente der Haustechnik beinhalten, je nach dem „Bedürfnis“ des Gebäudes.
Ziel war es, geeignete Gebäudetypen in Österreich für das RENVELOPE-System zu identifizieren und das Marktpotenzial serieller Gebäudesanierungen zu bewerten. Die Hauptkriterien für die Eignung sind die Gebäudenutzung, das Baualter, die Anzahl der Stockwerke, das Fassadendesign sowie der Zustand der vorhandenen Dämmung.
Das geschätzte Marktpotenzial für RENVELOPE in Österreich beläuft sich auf rund 71.500 Gebäude. Diese Zahl umfasst die Gesamtheit der Gebäude, die als technisch und ökologisch geeignet identifiziert wurden. Allerdings sind vom geschätzten Marktpotenzial nur etwa 10.000 Gebäude für eine sofortige Renovierung mit diesem System geeignet, auf Grund von wirtschaftlichen und rechtlichen Faktoren.

Dieses Projekt wird aus Mitteln des Klima- und Energiefonds gefördert und im Rahmen der FTI-Initiative „Vorzeigeregion Energie – Green Energy Lab“ durchgeführt.

Greening buildings is seen as one of the keys to climate-friendly construction. The new EU Buildings Directive (EPBD 2024) among other things relies on greenery to increase energy efficiency. But how strong is the actual cooling effect? And what can greenery do beyond cooling?
The HeinrichBiCool research project is investigating this using the example of a university building in Graz, which is being extensively greened. Currently still rare before and after measurements will provide valuable real data on temperature reductions, energy savings and comfort gains. Continuous monitoring records seasonal and diurnal effects.
In addition to cooling performance, the focus is also on biodiversity, rainwater management and cost-benefit analyses in order to provide sound findings for sustainable greening solutions.

Weltweit einzigartiger Messstand für Gebäudebegrünungen aufgebaut.

© AEE INTEC, Martina Majcen

Obwohl Baubehörden, Planende und Bauherrinnen sich zunehmend einig über die Wirksamkeit von Gebäudebegrünungen gegen negative Auswirkungen des Klimawandels sind, besteht aktuell dringender Bedarf, ihre Wirkungen valide zu quantifizieren. Wie viel Kühlenergie kann durch Begrünung eingespart werden? Wie sehr verbessert sich die Behaglichkeit in Innen- und Außenräumen und wie sehr kann eine Dachbegrünung der erforderlichen Dämmung zugerechnet werden? Zur Klärung dieser Fragen haben wir am Labordach bei AEE INTEC fünf mobile Fassadenbegrünungen fertiggestellt, die nach der Anwuchsphase wöchentlich vor unsere Fassadenprüfbox geschoben und detailliert vermessen werden. Die fachgerechte Bepflanzung wurde durch Mitarbeiterinnen der Universität für Bodenkultur in Wien ausgeführt. Mit der AEE INTEC Fassadenprüfbox haben wir die einzigartige Möglichkeit, die Auswirkungen von Fassadenbegrünungssystemen an zwei identischen Räumen objektiv zu vermessen.

“The energy transition to renewable energies cannot be reached without the intensive use of green hydrogen”, this statement can be heard often, and it should be discussed.
Hydrogen as a direct substitute for natural gas could offer several advantages - part of the existing infrastructure can be used, conversion technologies do not need to be changed and the energy supply is secure. But is this the case? Where will the green hydrogen that is needed come from in future? Will Europe shift from fossil dependencies to hydrogen dependencies as it will not be possible to meet the European demand with production capacities located in Europe? What price will Europe have to pay and is hydrogen the most suitable energy source or will there be competitive alternatives like ammonia, methanol, or dimethyl ether?
These are just a few questions raised that the current issue of “nachhaltige technologien” tries to answer on a scientific basis.
In addition to well-known technologies such as electrolysis, new efficient methods for biogas production, the application of methane pyrolysis or highly innovative technologies such as photocatalytic conversion of wastewater into hydrogen or methanol will be developed in future.
In order to successfully meet the challenges of the energy transition within the given timeframe, the use of all renewable energy sources is essential. It will be crucial to use all available technologies reasonably and efficiently. This is the only way Europe is able to become independent of external energy sources and global crises.

The ACR Woman Award has been presented to a female researcher from the ACR network in the field of science and technology since 2010 and makes their individual achievements visible, creates awareness of female career paths in research and, in the best-case scenario, motivates young women and girls to embark on a career in science and technology.
This year's ACR Woman Award was presented to Dagmar Jähnig for her 20 years of research in the field of solar thermal systems, energy storage methods and digital building twins.
Together with her team, Dagmar Jähnig has developed a software solution that enables real-time adaptation of the building simulation via a so-called digital twin. The methodology is based on a combination of real-time data, simulation techniques and intelligent control strategies.
A digital twin offers the opportunity to significantly reduce a building's energy consumption. A detailed real-time simulation model of the building and its system technology provides the control system with much information, which can be used to optimize the operation of heating, ventilation, and air conditioning. This makes it possible to respond much more precisely to the current weather conditions and the actual use of the building.

AEE INTEC wins one out of three ACR Innovation Awards

© ACR/APA-Fotoservice/Juhasz; Fotograf: Krisztian Juhasz

The cooperative technology development CEPA - thermal-regulating façade system developed by AEE INTEC and Towern3000 deals with the topic of building refurbishment at the level of technical solutions and was awarded the ACR Innovation Prize 2023. The technology focuses on the activation of existing building masses by means of multifunctional, serial façade elements, which, in addition to the insulation level, also include an energy-active level for conditioning the building (heating and cooling) from the outside. The prefabricated facade can be installed on the construction site in a minimally invasive manner and within a very short time. In addition to the heating and cooling functionality, CEPA can also be used to store energy in the building envelope. Thanks to a special design and installation process, the achieved thermal contact between the panel heating and the wall is used to heat the existing wall over the entire wall depth or, if necessary, to cool it.

Compared to conventional, non-serial refurbishment solutions, the technology impresses with a high degree of prefabrication and a holistic thermal-energetic solution in a single implementation step. AEE INTEC developed scientific tools for the industrial partner that accelerate and considerably simplify the decision-making and planning process of the CEPA system and thus form the basis for the scalability of the technology.

On September 6, 2023, Federal Minister Leonore Gewessler opened the annual event of the “Vorzeigeregion Energie” with the title "Energy Innovations Made in Austria - Opportunities for Austrian Companies on the World Market".

In the speeches of the Minister and of Climate and Energy Fund Managing Director Bernd Vogl, the successes of the research funding program "Vorzeigeregion Energie" were honored. The flagship project ThermaFLEX was recognized as an outstanding example: AEE INTEC was head of the large-scale research project implemented in the frame of the Green Energy Lab showcase region which won the Energy Globe Award Austria (Fire category) in June 2023 for its contribution to reducing greenhouse gas emissions of the district heating sector.
The project with 28 partners in Styria, Vienna and Salzburg used ten large-scale demonstrators to showcase that large-scale technical implementations are possible in a relatively short time. As soon as all demonstration plants of the ThermaFLEX project have been fully implemented, up to 45,000 tons of carbon dioxide can be saved each year. In addition to this direct contribution to climate protection, the elements and solutions developed will also serve as a blueprint for other national and international heating networks.

The lead project ThermaFLEX was funded by the Climate and Energy Fund and carried out in the frame of the Green Energy Lab which is part of the "Vorzeigeregion Energie" program.

 

Issue 03 | 2023 of „nachhaltigen technologien“ is online

Installation figures for compression heat pumps are steeply going up both nationally and internationally. In Austria, over 60,000 heat pumps were installed in 2022, representing a market growth of 60 percent compared to 2021. Predominantly, compression heat pumps are used for space heating in private residential buildings using outside air as the heat source. Despite the huge potential of applying heat pumps in existing multi-story residential buildings, in industry and commerce, as well as in local and district heating networks, these applications are still virtually nonexistent. The background to this fact is that, on the one hand, specific product developments are needed to cope with operating conditions that are significantly different compared to single family homes, and on the other hand, there is a lack of standards regarding different heat sources and their system integration. It is interesting to note that there are further promising heat pump technologies, such as rotating, thermoacoustic and thermally driven heat pumps suitable for these areas of application.

The present issue of the magazine "nachhaltige technologien" gives insight into pilot projects using compression and thermally driven heat pumps and reports on the state of development of rotating and thermoacoustic heat pumps.

Ausgabe 02 | 2023 der „nachhaltigen technologien“ ist online

Für ein Gelingen der Transformation unseres Energie- und Mobilitätssystems kommt Städten eine besondere Rolle zu. Denn global gesehen sind unsere Städte für 78 Prozent des Energiekonsums bzw. für rund 75 Prozent der CO2-Emissionen verantwortlich. Aufgrund eines flächenbezogen hohen Energieverbrauchs bei gleichzeitig limitierter Flächenverfügbarkeit für Energiekonversion ist die Transformation der Energieversorgung deutlich komplexer und herausfordernder als im ländlichen Raum. Vor diesem Hintergrund ist es essenziell wichtig, dass städtespezifische Transformationspläne erstellt werden, dabei auch Stakeholder und Bürger*innen eingebunden sind und die Zielsetzungen einer zukünftigen Energieversorgung verbindlich in Stadtent¬wicklungs¬konzepten niedergeschrieben werden. Einige österreichische Städte sowie auch zahlreiche andere europäische Städte folgen bereits diesem Weg und werden durch nationale Programme (in Österreich beispielsweise „Klimaneutrale Stadt“ und „Pionierstädte“) als auch durch internationale Programme (zum Beispiel „100 European Climate-Neutral-Cities by 2030“) gelenkt und unterstützt.

Der Schwerpunkt der „nachhaltigen technologien“ Ausgabe 02-2023 gibt Einblick in diese Programme, präsentiert konkrete Transformationsfahrpläne beispielhafter Städte und berichtet über Erfahrungen in der proaktiven Partizipation von Bürger*innen und Stakeholdern in urbanen Transformationsprozessen.

Start of pilot plant experiments at the lab of AEE INTEC for the upgrade of fermentation residues

© AEE INTEC

In the frame of the research project ‘BioProfit’ supported by the Austrian Cooperative Research (ACR), a process upgrading the digestate from biogas plants to valuable liquid fertilizer and humus is being developed. The solid phase of the digestate contains most of the plant-available nutrients and carbon, while the liquid phase contains particularly high amounts of nitrogen. Using a membrane distillation (MD) process, a high-quality liquid nitrogen fertilizer can be produced from the liquid fraction. This fertilizer can be deployed as a base fertilizer in agriculture, for example.

With regard to the development of the membrane distillation process an important milestone could be reached in November 2022: the test series using a container-scale MD pilot plant with large-scale membrane modules was successfully started. The aim is to investigate the 24/7 continuous operation process with regard to different fermentation residues from agriculture as well as the food industry and to analyze and further optimize the process under real long-term operation conditions. In addition to the optimization of the operating parameters, the focus is on the analyses of the product quality and the membranes used for the process.

 

AEE INTEC coordinates activities with respect to IEA ES Task 43

Thermal activation of building components has been used primarily for heating or cooling purposes. However, structural elements of buildings can also be part of the building’s energy storage devices by selective overheating or undercooling. Thus, these components offer advantages for the volatile, renewable-based energy system of the future. At this stage, however, standardized use of building components as energy and flexibility storages is not yet widespread, as key questions remain unanswered.

AEE INTEC therefore launched an initiative to define a new project (task) within the framework of the International Energy Agency and coordinated the definition phase. After a one-year definition period, the final work program was adopted by the IEA Executive Committee in mid-November 2022. Austria's strong role continues after the definition phase - AEE INTEC will take over the overall management of Task 43 with Christoph Rohringer as Task Manager.

Renewable and secure energy supply is of high importance for industry, intensified by the current energy crisis. Industrial companies need ready-to-implement solutions in all areas. Due to the high share of industrial heating and cooling demand in the temperature range below 400 °C with regard to total energy demand, and the high availability of applicable renewable technologies, a consortium coordinated by AEE INTEC has focused on energy efficiency, the use of waste heat, heat pumps, solar thermal, photovoltaics and PVT and necessary thermal storage in the frame of an R&D project.

A workshop at the end of the project "CORES - Integration of Combined and Renewable Energy Systems in Industry" took place in Vienna on 17th of November 2022. Three industrial companies were involved in the project and the methodology was developed, applied and simplified on the basis of their existing energy systems. The results, which included a quick check tool for easy identification of useful concepts, were presented and discussed in an exciting panel discussion with funding bodies, technology experts and stakeholders.

CORES was funded by the Climate and Energy Fund and carried out within the framework of the "Energy Research" programme
