None of the indicators underlying the 169 targets of the 17 UN Agenda 2030 Sustainable Development Goals (SDGs) allow for the tracking of buildings´ greenhouse gas (GHG) emissions. Due to the continuously decreasing GHG budget and the significant contribution of the building sector to GHG emissions, in this study a new indicator and implementation...

In diesem Zusammenhang liegt der Fokus darauf, eine Aus- und Weiterbildungsroadmap bis 2030 in Einklang mit den nationalen und europäischen Klimazielen zu entwickeln. Ziel ist es, da...
Zusammenfassung
Die UN-Agenda 2030 für nachhaltige Entwicklung bietet einen gemeinsamen Plan für Frieden und Wohlstand für die Menschen und den Planeten. Im Mittelpunkt stehen die 17 Ziele für nachhaltige Entwicklung (Sustainable Development Goals, SDGs), die einen dringenden Aufruf zum Handeln aller Länder darstellen. In Österreich haben sich dazu...
Purpose
The greenhouse gas (GHG) emissions caused by the construction industry account for an enormous share of total global CO2 emissions. The numerous construction activities therefore continue to reduce the remaining carbon budget. One lever for the reduction of these GHG emissions lies in the procurement process of buildings. For this reason, a...
In order to exploit the existing GHG emissions reduction potential of a building in the early design phase, approaches and incentives are needed to promote sustainable procurement already in the tendering and awarding phase. The objective of this study is to develop a Life Cycle Assessment (LCA)-based bonus/malus system for the public procurement o...
The construction industry adds a high share to global CO2 emissions and, thus, to the global climate crisis. Future buildings need to be planned, constructed, operated, and deconstructed in a lifecycle-oriented manner so that the building stock represents a capital asset for future generations. The greatest leverages for reducing a building’s CO2 e...
To make efforts for climate protection in the City of Graz (Austria) as effective as possible, the city has established a climate protection fund, from which the KNB (Klimafreundliche und Nachhaltige Baustandards) project emerged. In the KNB project, a new approach was developed on how the city can already request and implement sustainability crite...
One important measure to combat progressing climate change is compliance with and under no circumstances to exceed the decreasing greenhouse gas budget. Every economic sector must strive to make its ecological contribution to achieve this objective. The construction sector is largely responsible for these negative environmental burdens. Although tu...
Purpose
With a contribution of 39% to greenhouse gas (GHG) emissions, reducing the environmental impacts of buildings plays an undisputed role in achieving climate goals. Therefore, the development of projects with a low carbon footprint is of crucial importance. Although several active and passive solutions as well as design strategies have been d...
The interlinked character of the 2030 Agenda poses both a challenge and an opportunity in terms of coherent policy making. Accordingly, different methods have been used in approaching the interactions between SDG entities (goals, targets, indicators, policies, external entities) in several recent publications.
In this paper, we provide a review and...
In current complex building designs, sustainability assessments are often performed after project completion, with limited impact on building performance which results in missed goals in terms of quality, cost, and time. We address this problem by proposing a hierarchical reference-based know-why model to answer the research question "what is a sui...
Over the past decades, it has become apparent that increasing demands in the construction industry have repeatedly led to project delays and increased project costs in practice. These demands have increased as a result of international and national action plans that have been developed to achieve the climate target paths and, therefore, the necessa...
Air pollution is a global concern, especially in cities and urban areas, and has many implications for human health and for the environment. In common with other industrial sectors, the construction industry emits air pollutants. In scientific literature, the contribution the construction industry makes to air pollution is underexposed. This system...
The goal of this study, commissioned by the Austrian Federal Ministry of Digitalization and Economic Affairs, is to provide a scientific analysis of the economy-wide effects of the enhanced EU 2030 climate targets for Austria. It derives recommendations, including on the necessary framework conditions in Austria and beyond its borders that are need...
Das Projekt Universitäten und Nachhaltige EntwicklungsZiele (UniNEtZ) ‐ mit 16 Universitäten, dem Climate Change Centre Austria, der Geologischen Bundesanstalt und dem studentischen Netzwerk forum n ‐ entwickelt Optionen zur Erfüllung der Sustainable Development Goals (SDGs) der Agenda 2030 . Die Optionen können aber erst wirksam werden, wenn Gesel...
By limiting global warming to 2°C, the climate goals set by the United Nations in 2015 (Agenda 2030) will clearly be missed. The shrinking of our GHG budget has shown that the implementation of a weak sustainability concept-i.e. equal consideration of all sustainability dimensions (environmental, economic and social)-is not sufficient to meet the r...
With the ratification of the Paris climate agreement to avoid the uncompensated effects of climate change, 197 countries will have to dramatically reduce their greenhouse gas emissions in half by 2030. In the case of the urban space, roads are responsible for the consumption of 105M tons of bitumen and 115M tons of the world's greenhouse gas emissi...
Solving the problems of high energy consumption and high emissions generated by the urban road systems is of great importance for the construction of low-carbon cities. Several tools have been developed to establish a method to evaluate the carbon emission related to the life cycle of road pavements. However, the lack of key basic data such as ener...
According to sustainability research the world has exceeded four out of seven planetary boundaries. The areas of climate change, biodiversity loss, nitrogen cycle and land use have left the so called safe operating space for humanity. The built environment is one of the major contributors to environmental impacts. Especially the embodied energy dur...
In order to achieve the climate goals, the implementation of sustainable construction is becoming more and more topical in the construction sector. Due to very long service lifes especially in railway projects, the consideration of life-cycle aspects into the early design process is of great importance. Regarding the assessment of the economic pill...
Aufgrund multikriterieller Anforderungen im nachhaltigen Bauen nimmt die Komplexität in Entscheidungsprozessen zu. Ein begrenztes Bewusstsein für systemische Effekte kann zu früh in der Entwurfsphase von Bauprojekten zu ungenauen und / oder falschen Entscheidungen führen. Derzeit mangelt es an geeigneten Methoden, um einen auf mehreren Kriterien be...
Im Rahmen des vom steiermärkischen Zukunftsfonds geförderten Forschungsprojekts
„UNAB“ werden derzeit zwei Forschungsansätze zur Optimierung der Nachhaltigkeit
von Gebäuden verfolgt. Ziel des ersten Ansatzes ist die Operationalisierung von Nachhaltigkeitskriterien in der derzeitigen Planungspraxis von Gebäuden. Unter Berücksichtigung der Zielsetzun...
It becomes increasingly challenging to follow decision-making processes while designing sustainable buildings as various sustainability criteria must be operationalized to maintain the optimal integral building performance over its whole life-cycle. Because it is difficult to manage the numerous interdependencies between sustainability criteria as...

These roadmaps identified key measures for setting up a national qualification and training scheme and other measures for ensuring development of skill...
Due to multi criteria related decision making processes during the construction of
sustainable buildings, the operationalization of holistic building performance is
becoming increasingly challenging. The realization of sustainability aspects in
current construction practice calls for - next to precise stakeholder requirements - an
integrated and li...
Different users and investorś project preferences, often lead to trade-offs during the early design phase of a project. Currently, decisions of design options and their technical measures are mainly reduced to an instantaneously assessed criterion (i.e. energy efficiency) within the sustainability assessment of buildings. Due to criteria interdepen...
Purpose Sustainability assessments of buildings using the life cycle approach have become more and more common. This includes the assessment of the environmental performance of buildings. However, the influence of the construction products used for the fabric, the finishing, and the technical building equipment of buildings has hardly been describe...
