UniNEtZ- "Zukunftsdialog” (Dialogues for the Future) at the Natural History Museum in Vienna

©, Joanna Pianka

Everyone talks about transformation, everyone recognizes its necessity - but do we all understand it in the same way?

Scientists and artists from the project "UniNEtZ" have been searching for a common understanding of the much-discussed transformation. The UniNEtZ event "Dialogues for the Future" emerged from this discussion.
The so-called "Zukunftsbausteine" (Building Blocks for the Future) were created to concretize this vision. These "building blocks“ are intended to make the current state of research in various relevant disciplines accessible in such a way that they can be directly linked to political and social discourse. Numerous people from ministries, politics, the media, NGOs and various interest groups attended the "Zukunftsdialog" event at the Natural History Museum at the beginning of May to get engaged in the conversation.

FFG Project KRAISBAU officially launched with a kick-off meeting

The project consortium of 33 companies, start-ups and institutions will be researching and working over the next four years to implement a circular economy throughout the life cycle of buildings. This will be achieved in particular through the use of AI tools.

However, the project will not only focus on the planning and construction of new, circular buildings, but also on the question of how we can best deal with existing buildings in Austria. How can buildings and their components be digitally recorded? How can we reliably determine which components can be reused and how? How can the service life of buildings be extended? What applications are there for construction waste if a building has to be demolished after all?

The project consortium wants to find answers to these and other questions. The findings will be made available to the entire industry by means of factsheets, roadmaps and training courses.

Congratulation, Marco Scherz, PhD!

© NHB, TU Graz

We would like to congratulate Marco Scherz for the successful completion of his PhD thesis titled „Life cycle assessment-based procurement of buildings using the systemic know-why planning process“ under the supervision of Prof. Alexander Passer and Dr.Helmuth Kreiner. The PhD thesis was successfully defended on December 05, 2023 at Graz University of Technology. The examination committee was composed of Prof. Alexander Passer, Prof. Alexander Hollberg and Prof. Daniela Fuchs-Hanusch.

This study builds upon the recent EU directive on public procurement, advocating for the allocation of building contracts based on life cycle costing and consideration of external environmental impacts. To mitigate greenhouse gas emissions in the construction sector, the researcher introduces the "LCA-based bonus/malus system," a cost model that incorporates environmental building performance into bid prices and facilitates award decisions. Additionally, a hierarchical reference-based know-why model is utilized to uncover interactions between planning decisions, facilitating the future implementation of an environmentally optimized planning process through life cycle assessment (LCA) for building procurement. The development of these models establishes the groundwork for advancing a more environmentally friendly building procurement process in Austria, paving the way for further implementation steps.

Environmental impacts of Airium: An Innovative Insulation Material

© Perlmooser Beton GmbH

Airium is a mineral foam which is produced on-site thanks to a highly technological truck. It can be used for multiple insulation needs (attics, sub-screed, or walls), therefore replacing traditional plastic materials (EPS, XPS, etc.). A particularity of this insulation material is its ability to rapidly absorb carbon dioxide while it dries, during a process which is called “carbonation”. This compensates for almost half of the greenhouse gas emissions which are emitted during its life cycle.

The Working Group published an Environmental Product Declaration (EPD) for Airium in July 2022, in cooperation with PELMOOSER Beton GmbH. For an EPD, the whole life cycle of a product is taken into account, from manufacturing, to use, disposal and further recycling possibilities.

04-22 | Pro Sustainable Management (ProNaWi) publishes tool for sustainability assessment

The project aims to help consumers understand the amount of ressources and energy behind products at the supermarket. By making this information visible, the project supports sustainable purchasing decisions and ultimately a sustainable management and growth. 

A recently within the project published tool enables actors along the value chain all the way up to consumers to check and compare the environmental footprint of their products.
The tool was developed with the help of the Working Group and supports several vendors of organic produce so far.
Included in the footprint are manufacturing, packaging, transport, etc. ProNaWi displays the CO2 equivalent, as well as calculation details and information on data quality.
To speed up the assessment of products, a methodology has been developed that makes it relatively easy to combine existing product information and extrapolate it to new products using similarity analyses. 

Find out more about the project on the official website.
The ProNaWi research project is co-funded by the FFG.

01-22 | Austrian Citizen Climate Council

How can Austria become climate neutral by 2040?

Mandated by the Austrian parlament, the new Climate Council, a representative group consisting of 100 people with various backgrounds and different opinions on sustainability and climate change, will work together on recommendations concerning climate mitigation and adaptation actions for Austria.
Gentle scientific support is essential for the independent work of the Climate Council. The council is therefore supported by a 15-member scientific monitoring committee, in which scientists from many different disciplines are represented, including Alexander Passer for the field of sustainability in the built environment.

The main focus (i.e. transport & mobility, diet, clean energy, social justice,...) as well as the exact method of decision making are yet to be agreed on. 

Above all the success of the Climate Council will be measured by whether the measures it develops find their way into the political process and are taken into account by the government and parliament. The Federal Minister for Climate Action, Environment, Energy, Mobility, Innovation and Technology Leonore Gewessler promised to take the results very seriously (see press conference).

This was the Citizens' Climate Council 2022:

08-21 | Environmental modelling of building stocks – An integrated review of life cycle-based assessment models to support EU policy making

This new study by Martin Röck et al. presents a systematic review of both the latest scientific literature on environmental modelling of building stocks and related EU policy initiatives. The findings illuminate the strengths and limitations of existing approaches as well as the potential of such modelling and the required directions for future development to provide effective policy support.

Based on the assessment of 104 scientific papers, our study shortlisted and analysed 22 environmental building stock modelling approaches. While promising, these show various limitations on their effectiveness in supporting decarbonization efforts while avoiding burden shifting. Future building stock models should offer extended system boundaries and comprehensive life cycle assessment, improved hotspot analysis and impact monitoring across spatiotemporal scales. A long-term perspective on the entire building stock covering climate and other environmental impacts is needed, as outlined in the latest standards. By linking existing studies to related EU policy objectives, we identify various studies that investigate scenarios and strategies relevant to EU policy makers and highlight research gaps.

The publication can be accessed here.

08-21 | IPCC Report Climate Change 2021: The Physical Science Basis

The IPCC has finalized the first part of the Sixth Assessment Report, Climate Change 2021: The Physical Science Basis.

The report summarizes the current physical understanding of the climate system and climate change as well as the latest advances in climate science. It provides the latest information on warming projections, shows how and why the climate has changed to date, and provides an improved understanding of the human impact on the climate (including extreme events).

The key statements of the report are:

  • Global warming will reach or exceed the 1.5 ° C mark on average over the next 20 years.
  • The further warming intensifies the thawing of the permafrost, the loss of the seasonal snow cover, the melting of glaciers and the disappearance of arctic sea ice in summer.
  • Climate change intensifies the water cycle. This leads to more intensive precipitation events and floods as well as to increased drought in many regions.
  • Some effects of climate change may be seen more intensly in cities.

The good news is that significant reductions in emissions will have a noticeable effect on air quality within five to ten years, and after 20 to 30 years also demonstrably on the rise in temperature. 

The Climate Change Center Austria (CCCA) created a poster to illustrate the working method of the Intergovernmental Panel on Climate Change (IPCC) and the results of the report. It can be found here.

02-21 | TU Graz on the Way to Becoming Austria's First Climate-Neutral University

(c) Lunghammer, TU Graz

Based on the results of the Greenhouse Gas Accounting of Graz University of Technology, the University has adopted a roadmap to climate neutrality by 2030. With specific measures and in cooperation with all employees and students, Graz University of Technology plans to fulfill its social responsibility in terms of climate protection and is thereby one of the pioneers among Austria's universities.

Günter Getzinger (Project manager Climate-neutral TU Graz) and Alexander Passer (chairman of the Sustainability Advisory Board) were in charge of creating this roadmap to climate neutrality.

In this interview, they explain the strategy of TU Graz and what measures each employee can take to support Graz University of Technology on its path to climate neutrality. The university is essentially pursuing three strategies: increase in efficiency, eco-effectiveness and eco-sufficiency. The focus is on switching to electricity from renewable sources, low-emission heating and cooling systems, sustainable construction and reducing carbon emissions from transportation.
Biking or using public transportation and travelling by train instead of airplane on business trips is highly encouraged. The university subsidizes e-bikes, tickets for public transportation and the charging of electric cars and supports research projects especially in the area of sustainable construction.

01-21 | makingAchange: Online-Workshops with schools on Climate Change and greenhouse gas reporting

At the end of January and the beginning of February, Alexander Passer and Antonija Wieser, hold interactive online workshops for schools on the topic of climate change and greenhouse gas reporting. The workshops are part of the project makingAchange.
makingAchange is a cooperation project between science and schools. The CCCA - Climate Change Centre Austria, together with the Federal Ministry of Education, Science and Research, invited secondary schools to participate in that project on climate change and sustainability in Austria. The AGNHB is conducting the workshops for schools in the Southeast of Austria, namly in Styria, Carinthia and Burgenland.

The overall aim of makingAchange is to contribute to the transformation of society, to raise awareness and integrate the topics of climate protection and sustainability into the school environment as well as in the everyday life of pupils. More about other topics is to be found on the website.

We are looking forward to a great interesting insights, lively discussions as well as many greenhouse gas reportings of schools.

11-20 | Seminar "Techno-Economic Research Methods - How to perform a Systematic Literature Review"

On 25 November, Dr. Marcella Ruschi Mendes Saade, who is an employee at the Working Group since July 2020, held a lecture on how to perform a Systematic Literature Review (SLR) as part of a series of seminars organised jointly with the Institute of Business Economics and Industrial Sociology.

The seminar series deal with Techno-Economic Research Methods, which are crucial to every scientific discipline as they ensure rationality and verifiability of scientific findings.

In the seminar, participants were taught the different steps involved in performing an SLR to enable them to differentiate between narrative and systematic reviews, to develop answerable research questions, to design a search protocol and to organize and combine search outcomes.

Two more seminars will take place in December and January. The second one is also co-organised by the Working Group and will be held by Prof. Karen Allacker from KU Leuven on the topic of "Research methods with focus on Sustainability". Registration is open until January 25th 2021. Biking or using public transportation and travelling by train instead of airplane on business trips is highly encouraged. The university subsidizes e-bikes, tickets for public transportation and the charging of electric cars and supports research projects especially in the area of sustainable construction.

11-20 | Environmental Impact of Reinforcing Steel in Austria

Reinforcing steel is one of the most important materials in the construction industry and contributes substantially to the emissions of the building sector.
As there was no data on reinforcing steel for the Austrian context, the Working Group published an Environmental Product Declaration (EPD) in cooperation with the steel and rolling mill Marienhütte Graz in April 2020.

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. The complete report can be found here.

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.

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.

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."

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).

Buildings account worldwide for 40% of global energy consumption on 30% of GHG emission. Due to the fact that the building stock plays a key role in achieving these targets. Alexander Passer presented an optimal refurbishment strategy in terms of lowest environmental impact through life cycle assessment (LCA). Three facade refurbishment scenarios (none, minimum and energetic high quality) and onsite energy generation (solar thermal and photovoltaic panel (PV)) were evaluated. 


Individual user and stakeholder interests in the context of project requirements and goals often lead to trade-offs; especially during the early design stage of a building. Helmuth Kreiner presented a new systemic approach linking building assessment and network analysis based on the Austrian building assessment system (ÖGNI/DGNB) and using a reference project of a public office building in Austria.  Link to homepage: Sustainable Built Environment Conference

04-16 | Guest Lecture Prof. Dr. HABERT : Sustainable Construction & Environmental assessment

Cement is responsible of more than 7% of the total CO2 emissions coming from human activities and the tremendous cement demand in developing countries urge us to find alternative to traditional Portland cement. In this lecture, we will assess the environmental impact of traditional and alternativ. We will particularly have a look at innovative binders such as geopolymers or magnesium cement.

03-16 | Precast-concrete: transparency through environmental product declaration (EPD)

(c) Bau EPD GmbH
Vienna, March 29th, 2016. The Bau EPD GmbH published the new enviornmental product declaration „Frischbeton für vorgefertigte Betonerzeugnisse“ for the Austrian concrete and precast association. The declaration is the result of a three year research work with the TU Graz and a trendsetting step for the local industry.

Professional cooporation with TU Graz

Under the scientific leadership of the Working Group Sustainability Assessment it was accomplished to define a standard concrete for precaste-concrete products in consideration of all environmental factors. So it is possible to identify all environmental impacts of the concrete – from extracting the resources to manufacturing in the factory. The published EPD could be used for all Austrian sustainability assessment tools of buildings (ÖGNB, climb:aktiv, ÖGNI).  Link to the press release

03-16 | Outstanding paper award winner at SBE16 Hamburg

(c) TU Graz
The SBE16 Hamburg was successfully finished after several days of intensive scientific exchange. 600 representatives from science and practice, from 31 countries, presented their ideas and results on integration of sustainability aspects into the design, construction and operation of buildings as well as neighborhood and city development.One of the emphasis of the program was the development and testing of planning and evaluation tools which support sustainable neighborhood development. The need to involve all relevant actors was particularly stressed. The discussion was led about whether and how the implementation of the climate protection goals can be achieved by means of sustainable construction. The results of the surveys taken by the participants are available on the website of the conference. They show interesting experiences in the field of integration of sustainability issues in education of architects, engineers and executives for the housing and real estate industry.Many visitors took the opportunity to get informed about concrete projects and examples of neighborhood development in Hamburg. After evaluating, all results were recorded and incorporated into the preparation of the World Conference WSBE17 HongKong.

(c) TU Graz
WISBA is the Wienerberger Sustainable Building Academy organized and funded by Wienerberger for students of architecture, environmental engineering and civil engineering. In its third year WISBA 2015 is cooperating with universities from Austria (TU Graz, TU Wien), Belgium (VUB, KU Leuven), Hungary (Budapest University of Economics and Engineering), Italy (University of PISA), Poland (Politechnika Warsaw) and Switzerland (ETH Zurich). Within the WISBA program the students work in international and interdisciplinary teams on projects in the field of sustainable building solutions. Goal of the program is to provide highly talented students with an additional education in sustainable building – a key topic for Wienerberger. In 2013 Wienerberger startet WISBA with 12 students. In total 60 students worked on a broad range of topics reaching from sustainability assessment methods to specific sustainability challenges such as overheating of buildings in summer. The WISBA start conference is hosted every year at a different university (TU Graz, 2013; TU München, 2014; ETH Zurich, 2015) – followed by several workshops. From September until December 2015 24 students from 6 countries work in project teams on two research topics based on the case study of Building 2226 by architects Baumschlager Eberle under the academic mentorship of distinguished experts in sustainability and construction. The goal of WISBA 2015 is to conceptualize low-tech brick buildings that focus on two future scenarios – climate change and change of usage – all under consideration of the three sustainability dimensions – ecology, society and economy. At the start conference at ETH Zurich students were introduced into the case study of Building 2226 under the supervision of their mentors. At further workshops in Leuven, Warsaw, Budapest and Pisa students continue their work which will be presented at the result conference in December in Vienna.    

02-14 | 57th Discussion Forum on Life Cycle Assessment

(c) Discussion Forum LCA
Buildings are an important consumer of energy and an important source of greenhouse gas emissions. In the last decade buildings and their environmental impacts are getting more and more attention. Analytical tools are being developed, environmental information based on environmental product declarations is being standardised and several sustainability and environmental tools and labelling schemes are being used in Switzerland. The discussion forum will provide an overview on different tools, information and labelling schemes, highlighting common aspects and main differences. The application of life cycle based information in the planning process is presented from the perspectives of building owners, practitioners and industry. The situation in neighbouring countries is described and the influence of the European Union’s construction products' regulation on the current landscape of environmental tools and labels is discussed. Results from recent research projects are shown. Needs and expectations from the viewpoint of building owners, planners and architects, and suppliers, respectively will be discussed. The goal of the discussion forum is to support informed decisions about the most appropriate environmental information and labelling schemes for the coming decade.   Link to homepage: Discussion Forum on Life Cycle Assessment
