Design- & konstruktionsdagen 2020


Tema: Sustainable Concrete Structures

Välkommen till den årliga Design- och konstruktionsdagen som i år genomförs som ett helt digitalt event. Temat är "Sustainable Concrete Structures, hållbara betongkonstruktioner, och våra talare hjäpler oss  att utforska befintliga initiativ och framtida möjligheter att konstruera i och hantera betongkonstruktioner på ett sätt som är så hållbart som möjligt ur begreppets olika aspekter.


​Program:

13:00     Welcome – introduction
13:10    Sustainability of conrete structures in a life-cycle perspective
Karin Gäbel & Ingemar Löfgren, Thomas Concrete 
What can we do limit the environmental impact with today’s technology? The relationship between material and design.
13:35    Carbon free cement – a prerequisite for carbon free concrete
Bodil Wilmhelmsson, Cementa 
How can cement manufacturing be developed to reduce carbon emissions? When will concrete with no CO2-emissions be available?)
14:00    Short break
14:10    Sustainable optimization of bridges
Alexandre Mathern & Kristine Ek, NCC/Chalmers 
Interdisciplinary sustainability-driven design optimization using integrated parametric design, life-cycle assessment and multi-criteria decision making methods. How much can the sustainability impact be reduced by optimizing common types of bridges?
14:35    Shaping effective and sustainable structures
Philippe Block, ETH Zürich
15:30    Coffee break 
15:45    Adaptive reuse and restoration of concrete buildings and structures - Sankt Görans former school building in Stockholm
 Sven Olof Ahlberg, Kulturbyggnadsbyrån
16:10    Keeping concrete structures
Karin Lundgren, Chalmers 
Keeping existing structures is often the most sustainable alternative! How can we prolong the service life of structures and how do we know if they are safe to use?
16:35    Panel discussion with the presenters, led by the moderator.  Possibility for the audience to post questions during the seminar. 
Talking points:
What is most important to make concrete structures more sustainable? Now and in the long perspective? What are the obstacles that prevents the use of available technology to minimize environmental impacts? Which changes are needed in directions/regulations/political instruments to get sustainable concrete structures?
17:00    End of seminar 


Portraits of speakers

Speaker Bios

Sven Olof Ahlberg

Heritage consultant specialized in preservation and restoration of the 20th Century materials, such as concrete and steel. He has a degree in building conservation from Gothenburg University and is frequently used as a lecturer at several Swedish universities and institutions. Ahlberg is CEO and owner of Kulturbyggnadsbyrån i Sverige AB, a company specialized in historic concrete structures and buildings.  In recent years he has among other projects conducted national surveys of historic Railway and Road bridges on behalf of The Swedish National Board of Transportation. Ahlberg has also published several books, for example: Bevara betongen and Våra broar - en kulturskatt.

Philippe Block

Philippe Block is Professor at the Institute of Technology in Architecture at ETH Zurich, where he co-directs the Block Research Group (BRG) together with Dr. Tom Van Mele. He is director of the Swiss National Centre of Competence in Research (NCCR) in Digital Fabrication, and founding partner of Ochsendorf DeJong & Block (ODB Engineering). Within the NCCR, BRG researchers develop innovative structurally informed bespoke prefabrication strategies and novel construction paradigms employing digital and robotic fabrication.

Kristine Ek

Kristine Ek has been an environmental specialist at NCC for twelve years and a post-doc researcher at Chalmers for two years. She is interested in sustainability assessment of infrastructure in a life cycle perspective. Her focus is on life cycle assessment and sustainability assessment for optimization of construction materials and infrastructure projects. 

Karin Gäbel

Karin Gäbel, Sustainability Manager at Thomas Concrete Group. With wide experience in cement, concrete and sustainability, Karin manage and develop the sustainability work within the group. Thomas Concrete Group was first in Sweden to alreddy in 2012 offer concrete with a significantly lower climate impact. 

Karin Lundgren

Karin Lundgren is professor in Concrete Structures at Chalmers University of Technology. Her research has been ranging from large scale (complete buildings) to small scale (material level) within the field of concrete structures. Her main focus is assessment of existing structures, and she is internationally well-known for her work on structural effects of reinforcement corrosion.

Ingemar Löfgren

Ingemar Löfgren is R&D manager at Thomas Concrete Group and is an Adjunct Professor in Material integrated structural engineering at the Division of Structural Engineering, in the research group Concrete Structures, at Chalmers. Ingemar work with concrete and cementitious materials in many aspects, from fundamental materials research to structural applications. 

Alexandre Mathern

Alexandre Mathern has been working as a structural engineer for NCC for ten years and as a PhD researcher at Chalmers for four years. He is interested in integrating computational structural design and analysis methods with multi-objective design optimization and life-cycle assessment to improve the sustainability, performance and buildability of structures. Both in research and professional practice, he has focused on developing and implementing innovative design and construction methods for bridges and other civil engineering structures.  

Bodil Wilmhelmsson

Bodil Wilhelmsson, Project leader PhD, Cementa R&D. More than 20 years’ experience from cement manufacturing R&D activities. Worked with climate impact from use of raw materials and fuels for cement production as well as restoring of resources. Today focused on electrification projects aiming at developing enhanced carbon capture techniques.
