The Working Group Sustainable Construction of the Institute of Technology and Testing of Building Materials is offering a broad spectrum in the area of sustainability assessment of buildings, life cycle assessment (LCA), life cycle costing (LCC)  and systemic sustainability modelling including digitalisation and multi-criteria decision models.

Our research is dedicated on sustainability assessment methods, the work flow within the building design process and the applicability in the built environment as well as their successful implementation and realisation within demonstration projects. In our interdisciplinary projects our foci lie on the optimization of the environmental and economic performance by the use of life cycle assessment, life cycle costing, system analysis and multi- criteria assessment methods. 


08-20 | Biogenic carbon in buildings: a critical overview of LCA methods

The dynamic approach, considering that trees grow before the use of the harvested wood product. Dotted lines indicate the product systems that fall outside the building system boundaries. Hoxha, E., Passer, A., Saade, M. R. M., Trigaux, D., Shuttleworth, A., Pittau, F., … Habert, G. (2020). Biogenic carbon in buildings: a critical overview of LCA methods. Buildings and Cities, 1(1), 504–524. DOI:

The increasing pressure to reduce greenhouse gas emissions from buildings has motivated specialists to develop low-carbon products incorporating bio-based materials. The impact of these materials is often evaluated through life-cycle assessment (LCA), but there is no clear consensus on how to model the biogenic carbon released or absorbed during their life-cycle. This study investigates and compares existing methods used for biogenic carbon assessment. The most common approaches were identified through an extensive literature review. 
Deviation between the results obtained from different methods was 16% at the building scale and between 35% and 200% at the component scale. Of all the methods studied, the dynamic approach of evaluating biogenic carbon uptake is the most robust and transparent.

07-20 | Carbon budgets for buildings: harmonising temporal, spatial and sectoral dimensions.

Habert, G., Röck, M., Steininger, K., Lupísek, A., Birgisdottir, H., Desing, H., Chandrakumar, C., Pittau, F., Passer, A., Rovers, R., Slavkovic, K., Hollberg, A., Hoxha, E., Jusselme, T., Nault, E., Allacker, K., & Lützkendorf, T. (2020). Carbon budgets for buildings: harmonising temporal, spatial and sectoral dimensions. Buildings and Cities, 1(1), pp. 429–452. DOI:

This new study by Guillaume Habert (ETH Zurich), Martin Röck, Alexander Passer, Endrit Hoxha et al. explores the processes for establishing a carbon budget for residential and non-residential buildings. Target values for creating carbon budgets for buildings are important for developing climate-neutral building stocks. A lack of clarity currently exists for defining carbon budgets for buildings and what constitutes a unit of assessment—particularly the distinction between production- and consumption-based accounting. These different perspectives on the system and the function that is assessed hinder a clear and commonly agreed definition of ‘carbon budgets’ for building construction and operation. 
Find the detailed review of current approaches to budget allocation and the propsed framework to accommodate these different perspectives and spatio-temporal scales towards harmonised and comparable cross-sectoral budget definitions in the open access publication.

07-20 | BIM and LCA Integration: A Systematic Literature Review

Potrč Obrecht, T.; Röck, M.; Hoxha, E.; Passer, A. BIM and LCA Integration: A Systematic Literature Review. Sustainability 2020, 12, 5534. DOI:

To foster sustainable development, the environmental impacts of the construction sector need to be reduced substantially. Life cycle assessment (LCA) is the established methodology for the quantification of environmental impacts, and therefore has been increasingly applied to assess the environmental performance of buildings. By coupling LCAs with digital design tools, e.g., building information modeling (BIM), the identification of environmental hotspots and their mitigation is possible during the design process. The objective of the study is to identify the current integration approaches, and determine the pros and cons of the integration process from different viewpoints, namely, technical, informational, organizational and functional issues.

04-20 | Life Cycle Assessment Electronic Based Systems Center

In April 2020 the Working Group finished the LCA of the EBS-Building, that is currently under construction at Campus Inffeld.

In 2017, the rectorate commissioned the Working Group Sustainable Construction to assess all locations of TU Graz in terms of energy use for electricity, heating and mobility, use of fuels and materials and its canteens. This GHG assessment of Graz University of Technology was published in the GHG report 2017. An evaluation of the grey GHG emissions from the construction of buildings had not been included in this assessment. Therefore the Working Group analysed a reference building regarding its environmental performance including operational as well as grey energy. However, this report is not to be published yet.

Assuming a static energy mix, the most relevant factor on the environmental impacts of the EBS Center over the whole Reference Study Period certainly is the operational energy. Nevertheless, the embodied impacts of the building are also a major factor. Due to this significant share, it is recommended to include also the embodied impacts of buildings in the yearly calculation of the GHG emissions.

04-20 | Environmental Product Declaration published

Due to the extensive know-how in the preparation of Environmental Product Declarations (EPDs) in the construction industry (e.g. EPD-VöZ, EPD-GVTB) the Working Group Sustainable Construction was commissioned by the steel and rolling mill Marienhütte Graz to prepare an EPD for reinforcing steel.
As no suitable PKR-B document was available for reinforcing steels, this document was also prepared and is now publicly available to other EPD producers.

We would like to take this opportunity to thank Marienhütte Graz for the excellent cooperation and look forward to further joint projects.

03-20 | Sustainable Cities and Communities

In its mission statement Graz University of Technology committed to implementing the UN Agenda 2030 goals. In addition to contributing to the achievement of the Sustainable Development Goals (SDGs) in teaching, research and administration, TU Graz, together with the University of Graz, is responsible for SDG 11 "Sustainable Cities and Communities" within the UniNEtZ project.

„Städte und Gemeinden/Gemeinschaften spielen eine Schlüsselrolle für die nachhaltige Entwicklung in unserer Welt. Derzeit leben ca. 50% der Weltbevölkerung in Städten, bis 2070 werden 70% erwartet. SDG 11 zielt auf die Schaffung nachhaltiger Städte und Gemeinden (bzw. Gemeinschaften) und damit auf die Schaffung einer sozialräumlich gerechten und ökologisch zukunftsfähigen Lebensgrundlage für die Menschen ab. Durch den wachsenden Urbanisierungsgrad ist SDG 11 mit einem der Megatrends des 21. Jahrhunderts konfrontiert. Darin liegen gleichermaßen Probleme wie Potenziale, da es nicht nur auf die Verbesserung der derzeitigen städtischen Infrastrukturen und Lebenssituationen abzielt, sondern auch auf die Transformation hin zu sozial, ökologisch und ökonomisch nachhaltigen Gemeinschaften mit resilientem Charakter. Die wichtigste Herausforderung ist daher die Schaffung von Strukturen, die nachhaltiges Alltagsleben ermöglichen.“ [Allianz Nachhaltige Universitäten in Österreich (2020): UniNEtZ – Universitäten und Nachhaltige Entwicklungsziele – Perspektivenbericht. Wien, Innsbruck, Österreich. ISBN: 978-3-901182-74-7]

01-20 | uniko Declaration for Sustainability

"Universities support the demands of the Fridays For Future movement for the implementation of the Paris Climate Agreement and global climate justice and welcome their contribution to raising public awareness for the complex social, ecological and economic challenges." This is one of six points of the Uniko Sustainability Manifesto, which was decided this week by the Presidency of the University Conference (Uniko). Austria's universities are committed to "taking responsibility for sustainable action in teaching, research, knowledge exchange and university management in order to help shape the path to a sustainable and livable society".

The president of uniko, Sabine Seidler, emphasizes the role of the universities as "thought leaders", who will essentialy contribute to sustainable development through their extensive scientific expertise. This is also in the self-image of the universities "as a space for the creation of new knowledge", which contributes to social changes. This knowledge is represented in public "in the sense of freedom of research and teaching for the benefit of society to lay the foundations for evidence-based political decision-making".

11-19 | New study: Embodied GHG emissions of buildings – The hidden challenge for effective climate change mitigation

In this new study by Martin Röck et al., the importance of reducing embodied carbon of buildings for effective climate change mitigation is showed. By analysing hundreds of life cycle assessment case studies, a global trend and ways forward were identified. While operational GHG emissions are reduced due to energy efficiency improvements, the embodied GHG emissions - i.e. related to sourcing and processing of construction materials - are increasing.
The study shows, that embodied GHG emissions investment for the production of new buildings dominates in the first decade, making their reduction and effectiveness a fundamental aspect in reducing life cycle emissions. Find more about the methodology and the detailed analyse in the open access publication.

11-19 | WohnbauFACTS: Affordability and climate protection in housing are top goals

At the invitation of Landesrat Johann Seitinger, experts including Alexander Passer discussed the future of living at Kunsthaus Graz. Climate protection and the creation of affordable property were the focus of attention.
According to Seitinger, the building sector makes a very significant contribution to climate protection: "About one third of the progress made to date in climate protection comes from this area. Strict insulation standards and heating with renewable energy sources not only protect our climate, but also reduce operating costs."

Professor Passer presented the necessary mitigation and adaptation strategies to cope with climate change, especially in heavely built-up urban areas. These areas are going through a rapid phase of growth and the emergence of heat islands is threatening: "It is essential to plan buildings, open spaces and entire neighborhoods in advance to counter climatic change" says Professor Passer. Our cities then would not only be better prepared for climate change, but they would make an active contribution to climate protection.

10-19 | Certificate of Advanced Studies at ETH Zurich: Regenerative Materials

Guillaume Habert, head of the Chair of Sustainable Construction, ETH Zürich, is launching a new Certificate of Advanced Studies in “Regenerative Materials” dedicated to earth, bio-based materials and reuse materials.
The objectives are to teach the specificities of these low-carbon materials (supply, implementation, adapted architectural design, material properties, construction cost and planning, end-of-life, etc.) through practical experiments, inspiring examples (visits and guest lectures) and exercises based on real case study.
The team, composed of international experts (Wang Shu, Anna Heringer, Martin Rauch, Dominique Gauzin-Müller…) want to teach not only architects and engineers, but also members of city technical services, building contractors, NGOs, in order to globally raise skills in the low-carbon construction sector.
A first session will open in January 2020 (5 weeks of contact lectures during one semester). Courses will be hold in English in order to receive a Swiss and international public. A Master of Advanced Studies will open in January 2021 (2 semesters) and will go deeper into technical details.

09-19 | Graz declaration for climate protection in the built environment

At the Sustainable Built Environment D-A-CH Conference 2019, researchers adopted the Graz declaration for climate protection in the built environment.

An intact natural environment is not only vital for humankind but also provides the basis for further social and economic development. For more than 30 years, the international scientific community has provided a strong body of evidence on the increasingly high atmospheric concentrations of man-made greenhouse gases (GHG) and the need to reduce these in order to limit the damages and risks caused by global warming.

The operation of buildings is responsible for approximately 40% of Europe’s energy consumption and 36% of CO2 emissions, making them the single largest cause of energy consumption and GHG-emissions. In addition, there are energy consumption and emissions caused by the manufacturing of construction products for creation and refurbishment of buildings and constructed assets. 

The objectives of limiting global warming require translation into actions for the specific sectors and actors.

You can sign the declaration here.

All signatories can be found here.

08-19 | Book launch "Sustainable Design Process & Integrated Facades"

Buildings must be planned, constructed and operated in such a way that they represent a capital rather than a legacy for future generations.
In the research project UNAB, an interdisciplinary research team of TU Graz took up this challenge with the aim of developing new, integral and hybrid building envelopes with special emphasis on sustainability and implementation in the planning process. By merging two complementary research approaches and integrating different research methods in the areas of design, numerical simulations, life cycle assessment, risk analysis and systemic analysis, a milestone in the operationalization (assessability) could be achieved.

Book is available at TU Graz.

06-19 | Hermes – JPI Urban Europe Project

Starting in 2019, Hermes is an international research project driven by scientists in Norway, Austria and China focusing on the integrated evaluation of energy saving, emission reduction potential and management strategies for urban road systems.

Innovation strategies aiming to improve urban life and development must address the pillars of urban areas: their infrastructural system. In Europe, about 80% of the road network consists of asphalt pavements, requiring more than 275 million tons of asphalt mixture to be produced every year. The negative impact of this production in terms of fossil energy, air quality and resource depletion is immense. If we are to take great leaps towards a sustainable infrastructure this challenge must be addressed. For further information on the project please have a look at the website.

04-19 | Science for Future

Since 2018, pupils, students and other (young) people around the world, following the example of the Swede Greta Thunberg, are demonstrating for climate protection and calling for a courageous environmental policy in accordance with the 1.5 ° C target of the Paris Climate Agreement.
In April 2019, an international statement on the climate strikes of the Fridays For Future movement was published. The statement was signed by about three thousand international scientists and published on April 12, 2019 in the renowned journal Science.

"The concerns of climate protesters are justified and supported by the best available science. The current measures for protecting the climate and biosphere are deeply inadequate. We see it as our social, ethical, and scholarly responsibility to state in no uncertain terms: Only if humanity acts quickly and resolutely can we limit global warming, halt the ongoing mass extinction of animal and plant species, and preserve the natural basis for the food supply and well-being of present and future generations. This is what the young people want to achieve. They deserve our respect and full support."

11-18 | Growth in Transition

This year, the initiative Growth in transition is organizing its fourth international conference, entitled “Europe’s transformation: Where People Matter”, on 14–15 November 2018 at the Austria Center Vienna.
During the two-day event, plenary and parallel sessions will feature inspiring speakers from politics, science, civil-society and the private sector. 
Keynote speakers include Ban Ki-Moon (Co-Chair of the Ban Ki-moon Centre for Global Citizens and Former Secretary-General of the United Nations), Elisabeth Köstinger (Federal Minister for Sustainability and Tourism of Austria) and Frans Timmermans (Vice-President European Commission).
The conference will address the transformation towards a sustainable society from very different perspectives. Conference topics will range from social and distributional aspects of a fair society to the role of the financial sector enabling a sustainable transformation.

Graz University of Technology and the Alliance of Sustainable Universities in Austria organized a Session in cooperation with the Federal Ministry for Education, Science and Research, ETH Zurich and Karlsruhe Institute of Technology:

The Built Environment in Transition:
Adaption of Production and Consumption Patterns in the D-A-CH-Region

The aim of the session is to underline the need for a transformation of the built environment. Due to economic importance of the construction and real estate sector covering our human needs for shelter and infrastructure, the anthropogenic material flows and the high energy demand as well as the associated emissions, there is a great need for action in the direction of sustainable development. To tackle these challenges in the sense of the Global Grand Challenges, UN Agenda 2030 for Sustainable Development and the Paris Climate Agreement, a paradigm shift is needed in the construction industry (planers and contractors), on the part of procurers (public and private investors, real estate sector) as well as on the demand side (user needs and user behavior).
