Issue 04 | 2020 of "sustainable technologies" is online

Digitization influences our society in many ways. In addition to well-known developments in the communications industry, in the financial sector, in industry, in trade or in public administration, the topic of digitization increasingly finds its way into the energy sector. New methods and buzzwords such as "Internet of Energy", "digital energy twins", "data-based regulation", "artificial intelligence and energy", etc. are becoming more and more important. The reasons for this are manifold, but are mostly based on the enormous potential for saving energy and resources, increasing efficiency due to the control of process flows, and increasing the share of renewable energies. The opportunities for automated integration of customers including their habits are proving to be particularly promising and challenging at the same time.
The current issue of the magazine "nachhaltige technologien" presents exemplary and current research activities with a focus on digitalization in the energy sector and their expected impact potential. The lead article deals with the contradictively discussed topic „Digitization and Employment“.

The EU H2020 horizon project CRAVEzero summarizes proven and new approaches to reduce the costs of near Zero Energy Buildings (nZEBs) at all stages of the life cycle. Within several case studies all over Europe, extra costs for nZEBs are revealed in relation to processes, technologies, and building operations.

CRAVEzero defined an integrated approach for planning and constructing a new nZEB that reduces the current design phase up to 20%. In particular, the process map offers a comprehensive overview of the phases, activities, and actors involved during the life cycle of a nZEB, identifying the possible pitfalls and bottlenecks and relevant countermeasures. Thanks to an optimised nZEB design with the CRAVEzero parametric method, it was shown that it is possible to save up to 16% of the financing costs, 23-29% of the operational costs and up to 30% of the replacement and investment costs.

Main Results:
❶         Reference schemes for nZEB urban planning and building design process
❷         Structured methodological approach to optimise integration of renewable and
              nZEB technologies
❸         Potential to reduce life cycle costs demonstrated by relevant case studies
❹         Demonstration of co-benefits: optimal architectural/building configurations for high-quality
              living/working environments and real estate value
❺         nZEBs lean management protocols
❻         60+ low LCC nZEB business models

Renewable energy sources in district heating and cooling as a path to climate-neutral cities

EUREC member AEE INTEC (Austria) is partner in the H2020 project RES-DHCRenewable Energy Sources in the District Heating and Cooling sector, which kicked off in October 2020 and will focus on increasing the share of renewable energy in district heating and cooling systems across Europe. 15 project partners from 8 countries including research institutes, companies and cities from Germany, Switzerland, Austria, Italy, France, Poland and Denmark as well as the European umbrella organisation EuroHeat & Power, based in Brussels, Belgium have joined forces to drive the decarbonisation of the DHC sector.

This new project aims to support key actors, including industry players and policymakers, in achieving the goals of the Renewable Energy Directive RED II. Specifically, the project focuses on the goal of increasing the share of renewable energy in district heating systems by at least 1% annually. In six model regions across Europe, the project is gathering experience and building capacity on how best to transform existing urban district heating systems towards low-carbon supply. These model regions are Baden-Württemberg, the region of Graz, Parma and Aosta, Szczecin and West Pomerania, Auvergne-Rhône-Alpes and the Swiss Cantons.

The aim is to empower actors along the entire value chain to cooperate with each other and work towards the goal of sustainable heating and cooling. The transfer of know-how and best practice examples from the model regions to other regions should increase the replicability and maximise the impact of the project outcomes.

Within RES-DHC, AEE INTEC will bring in its wide experience in the district heating and cooling and coordinate the implementation of different measures in all model regions, aiming at a transition towards 100% renewable district heating. These measures are discussed and developed previously with all partners and stakeholders in the model regions and include next to technical measures also long-term planning, business model development and user integration. Here specifically, AEE INTEC together with the partners from the Graz model region (Energie Graz, City of Graz) will focus on the decarbonization of the Graz district heating system and will continue the already ongoing and successful transformation process in Graz.

Energy-flexible buildings towards resilient, low carbon energy systems

The energy flexibility of different buildings and the way how this energy flexibility can be characterized were investigated in the project "Energy Flexible Buildings" of the International Energy Agency (Energy in Buildings and Communities Programme - IEA EBC Annex 67). Within the final phase of this EBC project, areas in which further research is needed were identified to ensure that the energy flexibility of buildings is indeed a support for future energy networks. These fields of investigation are:

  • the resizing of individual buildings to building clusters (aggregation),
  • energy flexibility and resilience in energy systems with different energy sources like electricity, district heating / cooling and gas,
  • the acceptance / commitment of the stakeholders and
  • business models

A new project of the International Energy Agency (IEA EBC Annex 82 - Energy-flexible buildings towards resilient, low carbon energy systems) is dedicated to these topics. The project started in November 2020 and will run until the end of October 2024.

The method allows the detection of small-scale inner-city heat island effects and pollutant concentrations. In the scope of urban planning the method is used for the evaluation of the thermal situation of public places, for example, and allows a cost-effective and time efficient acquisition and evaluation of measurement data by means of drones and by using high-resolution thermographic and multi-spectral cameras.

The project is supported by the Federal Ministry for Climate Protection, Environment, Energy, Mobility, Innovation and Technology.


Change of existing urban district heating and cooling systems from fossil to renewable energy sources

On 23th September 2020, the official kick-off of the RES-DHC project - conversion of existing urban district heating and cooling systems from fossil to renewable energy sources - took place in Graz City Hall.

The project aims to investigate the various challenges of market acceptance associated with the conversion of district heating and cooling systems to higher shares of renewable energy sources. Stakeholders are to be supported in (over-) fulfilling Art. 24 of the Renewable Energy Directive II (Directive 2018/2001) by developing solutions and instruments. The main objective of the project is to support the transformation of existing urban district heating and cooling systems in six participating regions (DE, AT, IT, PL, FR and CH) towards renewable energies and thereby - from these practical cases - to derive technical and organizational solutions for such transformation processes. In the work package "Making the change" led by AEE the regional framework conditions for stakeholders shall be improved, decarbonization activities shall be started and guidelines shall be derived which are applicable in all participating regions.

This project is funded by the European Union (Horizon2020).



At the BauSIM2020 conference hosted this year by Graz University of Technology a contribution of AEE INTEC has been awarded among 133 internationally submitted scientific publications.

Daniel Rüdisser, Tobias Weiss and Lukas Unger (Skyability GmbH) have been awarded the BEST CONFERENCE PAPER AWARD for a publication laying the scientific foundation of an innovative method concerning the three-dimensional measurement and calculation of thermal comfort in urban areas. The method has been developed in the course of the project Smart City Sensing funded by the Federal Ministry of Climate Action, Environment, Energy, Mobility, Innovation and Technology. It allows analysis and generation of insightful thermal maps of intra urban heat islands by means of unmanned aerial vehicle measurements and complex numerical calculations.


Final Meeting/Project conclusion DeStoSimKaFe

Picture of

Vom 10.-11.09.2020 fand das Abschlusstreffen des Projektes DeStoSimKaFe bei AEE INTEC in Gleisdorf statt. Im Zentrum des Projekts DeStoSimKaFe stand die Anwendbarkeit und Umsetzbarkeit innovativer und nachhaltiger Wärme- und Kälteversorgung auf Basis Kalter Fernwärme zu. Um das zu erreichen, erfolgte die Entwicklung komplexer technischer Systemlösungen und von methodischen und simulationstechnischen Grundlagen für die Konzeption, Planung und langfristige Bewertung solcher Systeme. Aufbauend auf die erarbeiteten Systemlösungen und der technisch/ökologischen Bewertung werden für maßgeschneiderte Produkte und Dienstleistungen für Kalte Fernwärme erarbeitet, die dann in eine ökonomische Bewertungsmethode einfließen. Durch das breit aufgestellte Konsortium aus Forschungseinrichtungen, Wärmepumpenproduzent, Beratungs- und Planungsunternehmen und einem Energieinstitut konnte eine solide Basis für die Beantwortung der Forschungsfragen geschaffen werden.

Die beiden intensiven Tage des Abschlusstreffens wurden genutzt, um finale Projektergebnisse zu diskutieren, die Berichtslegung mit den Partnern zu koordinieren und sich über die jeweiligen Branchen-Entwicklungen auf den neuesten Stand zu bringen. Darüber hinaus wurden potentielle Follow-ups und zukünftige Forschungsfragen erarbeitet und eine umfangreiche Reflexion durchgeführt.

Als konkrete Forschungsresultate wurden Modelle für die Simulation und Bewertung von verschiedensten Systemkonfigurationen auf Basis kalter Fernwärme erstellt. Diese wurden zur Langzeitbewertung der jeweiligen Systeme unter sich ändernden Rahmenbedingungen genutzt. Daraus konnten die Verhalten, Einflüsse und vor allem die Einsatzgrenzen einzelner Systemvarianten und Einflussparameter abgeleitet werden.

Als wichtigste Take-aways zeigten sich, dass für eine erfolgreiche Implementierung von kalten Fernwärmelösungen eine gute Verfügbarkeit von lokalen Wärmequellen wie Abwärme vor Ort unabdingbar sind. Das Konsortium stimmt ferner überein, dass es vielerorts Abwärmepotential nicht erkannt wird: bereits niedertemperaturige Ströme (z.b. bei 30°C) stellen sehr gut nutzbare Potentiale dar, die in Kalte Fernwärme-Anwendungen einem enormen Beitrag liefern zu einem Ausstieg aus ineffizienter und fossiler Wärme- und Kälteversorgung liefern können. Hier besteht jedoch noch weiterer Bedarf an Demonstrationsprojekten und Umsetzungen, um dieses Potential auch sichtbar zu machen für die breite Öffentlichkeit.


Issue 03 | 2020 of "sustainable technologies" is online

In future one of the big challenges will be to implement climate-friendly energy supply systems in buildings and neighborhoods. The focus for Central Europe still is heating in wintertime, but the energy input for cooling devices during summer is increasing. Although there is a large number of research projects in the energy field, there are still barriers to implement innovative solutions in practice.

In the current issue of the magazine "nachhaltige technologien", innovative demonstration buildings and quarters are presented. Diverse solutions prove that energy efficiency, energy savings and well-being of the inhabitants can be implemented in an affordable manner. Monitoring results confirm the innovative approach and the actually very low energy consumption.

Building component activation, energy management systems, ice storage solutions, digitalization concepts for residents are just a few keywords that will be indispensable in future energy and building technology concepts. The examples provided in the magazine are intended to encourage the successful implementation of proven standard solutions as well as new developments and innovations.


Smart city surveying

In August 2020, experts from AEE INTEC and Skyability took advantage of excellent weather conditions to investigate urban heat islands (IUHI) in the old city of Graz.

The innovative method developed by AEE INTEC in the frame of the FFG-funded project SmaCiSe uses a drone equipped with a thermographic and multi-spectral camera to precisely detect both heat radiation and reflected solar radiation. In hot urban environments, the radiation temperature significantly determines the sensation of heat, both in terms of the subjective perception of temperature and objective physiological stress. The project team uses sophisticated measurement technology and complex numerical methods to determine the above mentioned radiation parameters as precisely as possible.

A comprehensive article was published in the newspaper (Kleine Zeitung, 23-08-2020), and a report will shortly be broadcast in the programme Road to Digital Austria on ATV and Puls 4.


News from the lead project giga_TES

Large-scale thermal energy storage systems (TES) of about two million cubic meters increase the flexibility of district heating systems in transforming the supply system to 100% renewable energy through seasonal heat storage. Building on the know-how gained in the project giga_TES with respect to large-scale thermal energy storage for renewable district heating systems, a demonstration project in Austria is to be implemented. The expertise gained in the project giga_TES regarding large-scale thermal energy storage for renewable district heating systems should be integrated to a follow-up demonstration project in Austria.

On 18 and 19 June 2020, the semi-annual consortium meeting of the project partners took place as a virtual meeting. The consortium consists of four Austrian and two European research institutes and twelve key companies of the European materials, components and construction industry as well as engineering offices and district heating network operators. The experts reported of successful material and component tests leading to patent applications in the field of storage components and covers for large heat storage tanks. Furthermore, results of the validation of simulation-based storage and component models were on the agenda. The project partner Planenergi presented projects implemented in Denmark lately. 

Besides technical optimisations, lifetime analysis for large heat storage systems and holistic system simulations of actual district heating systems, models for assessing economic efficiency are in the focus of the final project phase.

Further information and results of the lead project can be found on the project website. https://www.gigates.at/index.php/de/

The project "giga_TES" is funded by the Climate and Energy Fund and is carried out within the framework of the programme "Energy Research (e!MISSION) - 3rd Call for Proposals in the Frame of Energy Research 2016".


Create - compact thermal energy storage system

The CREATE project developed a heat battery, that can store heat in a compact way with virtually no heat losses. With this storage technology, heat from solar collectors can be stored in summer to be used for room heating and warm tap water in winter. The EC-funded project developed storage material and components and put them together in a prototype heat battery that was demonstrated in a house in Warsaw, Poland.


Waste heat recovery for industrial processes

Jürgen Fluch (AEE INTEC) moderated the risk minimization section in one of two four-hour workshops in the scope of IEA IETS Annex 15 / Task 3 (International Energy Agency Industrial Energy-Related Technologies and Systems - Industrial Waste Heat Recovery), which took place on 25 and 26 June 2020.

Economic, financial or technological barriers are challenges for the implementation of waste heat projects in industry besides soft facts like lack of confidence or subjective risk assessment. Unforeseeable changes of the energy prices, a lack of reliable business models for financing or technological problems that occur during the planning and operation phase are further reasons why waste heat utilisation projects are hesitantly implemented.

By investigating and combining methods for identification and quantification of usable waste heat in industry, by estimating future influencing factors on waste heat projects, aspects of operation in industrial energy systems as well as risk assessment, the IEA IETS Annex 15 / Task 3 analyses possibilities and approaches to solutions and presents innovative demonstration projects that have already been implemented or that are planned.

Issue 02 | 2020 of "sustainable technologies" is online

Because of Covid-19, numerous scientists of various disciplines called on politicians to push on integrated measures that would both boost the economy and help protect the climate in the long term. Dr. Fatih Birol, Executive Director of the International Energy Agency (IEA), sees this path as essential and gives recommendations for policymakers.

In the context of security and resilience of the energy supply hybrid renewable energy systems play an important role. In recent years, hybrid solar technologies (PVT) have developed in the shadow of the single technologies, namely photovoltaics and solar thermal energy. Now the technology is established with a collector area of 1.17 million m² installed worldwide by the end of 2019. PVT systems have a much higher efficiency per unit area than comparable single technologies. This makes them particularly interesting for the building sector due to the increasing demand of locally generated renewable energy.

Read more about hybrid solar technologies in the current issue of the magazine "sustainable technologies".

Methodology Development for Accelerated Generation of Thermal Energy Storage Models

A new PhD thesis at AEE INTEC deals with the numerical modelling of new energy storage technologies.

The main goal of the thesis is the development of general approaches and methodologies for building numerical Thermal Energy Storage (TES) models for dynamic system simulations. With the elaborated methodologies the development of new TES models should become faster, more efficient and less costly. In order to enable an accelerated modelling process the future promising, acausal, equation-based and object-oriented modelling language Modelica is used.

Another objective is the development and testing of these general methodologies by the development of two new built, scientifically proven and well validated TES models for dynamic systems simulations, which will be used at AEE INTEC in the scope of ongoing national and international research projects. One of the models refers to large-scale pit TES and the other one refers to compact thermochemical TES.  These two models will allow in-depth analysis, design and optimization of these emerging TES technologies  and thus enable an accelerated market launch and the integration into future energy systems.

This PhD thesis is funded by the Austrian Research Promotion Agency (FFG) in the framework of the program “Forschungspartnerschaften: Industrienahe Dissertationen 2020 - 6. AS Forschungspartnerschaften“.
