One complete outfit specialising in finding sustainable living solutions for the future. Those living in the 29 apartments have now been a part of the innovation project for a year - a project which constitutes cooperation between trade and industry, city and academia. 2000 sensors spend 24 hours a day collecting data which can be used to find new living solutions for the future.<br /><br />The 1-year anniversary was celebrated on Tuesday September 19. The visit began at <span><span></span><span> Johanneberg Science Park <span style="display:inline-block"></span></span></span>with a presentation of some ongoing research projects <span><span style="display:inline-block"></span></span>which are linked to the HSB Living Lab building and to Chalmers. Presentations included building-integrated solar panels, city simulations and research into how much reconstruction goes on within the apartments. <br /><br />During his welcome, MD of HSB Gothenburg <strong>Lars Göran Andersson l</strong>ed three cheers for HSB Living Lab.<br />   “We now have another nine years of research to go,” he said, indicating that HSB Living is a ten-year project.<br /><br /><img src="/en/areas-of-advance/buildingfutures/news/Documents/HSB_LivingLab1ar_170919_2.jpg" alt="HSB_LivingLab1ar_170919_2.jpg" style="margin:5px" /><br /><br />After Peter Eriksson had been shown around the premises, a panel debate was held on the subject of “<strong><em>Smart cities, what do we mean by that</em></strong>?” where discussions concerned the challenges faced by researchers, housing companies and the politicians. The subjects of ownership, virtual town urban planning, the importance of abbreviated construction processes and smart cities and the way to get the most from the research which exists and is ongoing at HSB Living Lab were debated while many of the audience were standing all the way down to HSB Living Lab’s modern laundry.<br /><br />The moderator was <strong>Lars Marcus</strong>, Professor of Urban Design and Planning at Chalmers.<br /><br />The panel:<br /><ul><li>Peter Eriksson (MP), Minister for Housing and Digital Development</li> <li>Anders Lago, Chairperson of the HSB Association</li> <li>Anders Logg, Acting Area of Advance Director Building Futures</li> <li>Anna Dubois, Vice President of Chalmers</li> <li>Mats Bergh, MD of Johanneberg Science Park</li> <li>Ann-Sofie Hermansson (S), Chairperson of the Municipal Board</li></ul> <br />Peter Eriksson concluded the panel debate confidently.<br />   “I think it’s all about using the new opportunities provided by new technology to build a more humane society where we invest in quality of life where people will be able to socialise and think of each other with love and kindness rather than distance themselves.

An important part of this challenge is to address the potential role of place and spatial design. This could be a paradigm shift that is necessary for changing current and future circumstances.  </div> <div> </div> <div>This challenge is too monumental to be resolved by any one person or discipline. This thesis contributes to the larger story through a smaller story: one about the potential relationships between place-making, regeneration and designerly thinking. </div> <div> </div> <h4 class="chalmersElement-H4">Regenerative design and place-making</h4> <div>More specifically the thesis focuses on place-making, particularly the perspective of spatial design and experiences of the built landscape, and how this is affected by and can affect our relationship to ´waste-making´. </div> <div> </div> <div>Mainstream sustainability focuses on avoiding scarcity through austerity and efficiency. It tends to convey that human activities are de facto bad for the environment and measures its successes as being “less bad”. Regenerative design theory problematizes mainstream notions of sustainability that reinforce human-nature dualisms and perpetuate linear systems of resources and power. Regenerative design stresses that we must shift into a mindset that recognizes that societies (and their economies) are inseparable from ecologies, and that local and global communities are made up of human and nonhuman subjects. It does not deny that we need to reduce the negative impact of human activities. However, it argues that human activity is not de facto bad for the environment and proposes to shift the focus of our efforts to increasing the positive effects of human activities.</div> <div> </div> <div>An important part of the solution to this problem, according to regenerative design theory, is to reconsider and rewrite a “narrative of hope”, stories of how we can change the world. Stories told and enacted within their cultural socio-ecological contexts can promote certain values and beliefs that build co-creative and co-evolutionary partnerships for regenerating resources and the notion of “the good life”. </div> <div> </div> <div><h4 class="chalmersElement-H4">Study areas – waste to resources and more </h4></div> <div>The areas studied represent publicly shared places where waste has been used as a resource or contributes to the process of being turned into a resource.

Each place and activity tells a contextually and individually different, yet similar, story of hope, renewal, contribution and creativity. The places which contributed most to such a narrative, were the ones that included ‘making practices’; what I call ‘making-places’. It is clear from these studies that the incorporation of waste-resource conversion in public and common life is possible, and can have many benefits for psycho-social wellbeing and the experience of the built landscape. They also add new dimensions to the experience of place, and call into question our common notion of what ‘public space’ is and can be used for”, says Sigrid Laurel Östlund. </div> <div> </div> <div>The Main Supervisor is Professor Jaan-Henrik Kain, Department of Architecture and Civil Engineering, Chalmers University of Technology with Artistic Professor Henrietta Palmer, Mistra Urban Futures as Co-Supervisor. </div> <div> </div> <div>“We are all impressed by the significant contribution made by Sigrid Östlund, taking us beyond often watery applications of ”sustainability” towards a generative architectural practice.

In order to create a network and develop a common vision and plan for how Chalmers can become stronger in globally-oriented sustainability research, Chalmers Initiative for Innovation and Sustainability Transitions (CIIST) organised a collaborative workshop at the end of May. <br /><br />More than seventy people from different parts of Chalmers, University of Gothenburg, Sida, student organisations, companies and civil society gathered for the workshop. Organiser Helene Ahlborg, researcher in environmental systems analysis and active member of CIIST, is very pleased with the turnout. <br /><br />“The level of participation shows that these are issues that many are passionate about. We see the global issues as crucial to our relevance and attractiveness as a university, and we found that we have the skills needed to further develop Chalmers' work in this area,” says Helene Ahlborg.<br /><br />For her, it is obvious that Chalmers has a lot to gain from becoming stronger in global sustainability research.<br /><br />“The biggest challenges we face require us to take them on with a global perspective. We also have a lot to learn from being present in poorer parts of the world, since many new innovations, ideas and solutions of the future will emerge in these contexts.” <br /><br />But, it is also about becoming an attractive university in the eyes of students. Many committed students want to take part and solve the world's problems; in response Chalmers must be able to offer them the right education.<br /><br />Helene Ahlborg's next step will be to create working groups that build on the work from the workshop to formulate a strategic vision and action plan this autumn.<br /><br />“The ball will then keep rolling over the next year and we will follow up on suggestions and drive them forward in different ways. We want to take advantage of the energy that exists and all of the initiatives already taking place within different organisations and create a collective arena and benefit in relation to these,” she says.<br /><br />The workshop was funded by the Energy and Building Futures Areas of Advance, as well as the Department of Energy and Environment.<br /><br />Text: Ingela Roos<br />Tue, 13 Jun 2017 17:00:00 +0200 Gothenburg together with Yale<p><b>​​The development of Älvstaden continues to attract international interest.

Additionally, she has evaluated how design can contribute to energy conservation by investigating how the design of an energy feedback system and everyday kitchen appliances such as kettles and toasters, influence energy use in everyday life. The insights gained point to the need of designing artefacts in a way so that they provide preconditions that enable a less energy-reliant everyday life.<br /><br />Anneli holds a Licentiate of Engineering degree in Human-Technology-Design as well as a Master of Science degree in Industrial Design Engineering from Chalmers University of Technology. She became interested in the topic of Design for Sustainability during her undergraduate studies where she had the opportunity to address issues related to energy conservation as part of the Master thesis project, which made her continue exploring this topic as part of her research studies. <br /><br />In the future Anneli will continue to explore opportunities for addressing sustainability challenges through design.

But research at Chalmers shows that costs and CO2 emissions can be reduced by diverting buildings’ use of thermal energy to other times of the day and night.</b></p><div><span style="background-color:initial">District heating is generally an environmentally friendly method of heating buildings. But need varies substantially during a 24-hour period, and to meet peak demand, many district heating producers are forced to fire up expensive, fossil-fuel back-up boilers.</span><br /></div> <div><br /></div> <div>But Johan Kensby, a Building Services Engineering researcher at Chalmers, has now demonstrated how to avoid this in a cost-effective way. In the first part of his doctoral project he observed that thermal energy can easily be stored in buildings, which creates good conditions for evening out the load on the district heating system (read more in <a href="/en/areas-of-advance/energy/news/Pages/Thermal-energy-storage-in-buildings-makes-district-heating-more-climate-friendly.aspx">Thermal energy storage in buildings makes district heating more climate-friendly</a>).</div> <div><br /></div> <div>In the second part of his doctoral project he investigated how the use of district heating can be controlled in practice. Kensby conducted his research in collaboration with the company Göteborg Energi. Together their work included performing an extensive test with varying hourly prices to 19 residential properties. Each property had been equipped with a control system designed to heat the property as inexpensively as possible. As a result, the properties moved their use of thermal energy to the times with the lowest production costs and least environmental impact.</div> <div><br /></div> <div>“This is a very cost-effective way of saving money and sparing the environment in district heating production. Indoor temperature sensors and connected control systems are becoming increasingly common in properties, so software is all that’s needed,” says Kensby.</div> <div><br /></div> <div>In terms of environmental impact, Kensby has calculated that controlling 20 percent of the properties in the district heating network can reduce the use of fossil-fuel boilers for thermal energy by 25 percent.</div> <div><br /></div> <div>“This is financially beneficial and benefits customers and the environment. We are now continuing to work on creating attractive offers for our customers based on Johan’s results,” says Ulf Hagman, Development Manager at Göteborg Energi. </div> <div><br /></div> <div>The business model is as yet unwritten, but Johan Kensby thinks that the best method is for the energy company to provide the investment and heating control function and then share the financial gains with its customers in a suitable way. The challenge is to find a business model that distributes profits and risks fairly, while also being simple to communicate.</div> <div><br /></div> <div>Kensby says that his collaboration with Göteborg Energi, where he has spent a lot time working on site, has been one of the most enjoyable aspects of his doctoral position.</div> <div><br /></div> <div>“I’ve had the opportunity to work close to real conditions, and the results of my calculations have been used in practice on a large scale.

For me, being able to make visible our profile area “Responsible resource management” is wonderful and I hope that it will both attract more researchers to Chalmers and lead to more collaborations.  <br /><br />The motivation for finally choosing Chalmers and partners as organisers of the event is partly their strong foundation in both national and international networks and the industry behind the application, and partly the way in which the programme for the conference has been structured, based on the <a href="">UN’s sustainable development goals</a>.  <br /><br />     - The platform with Chalmers and its areas of strength alongside RISE, Johanneberg Science Park and the City of Gothenburg constitutes a very clear example of the interoperability aptitude that we have. It is also great that we are able to contribute to the specification of the global sustainability goals”, Holger Wallbaum continues.  <br /><br /><a href="">The next WSBE conference</a> will take place in Hong Kong in June 2017. The overall goal of the conferences is to increase knowledge and skills within the design, development, construction and operation of buildings and urban systems. The originator of the conference is <a href="">iiSBE</a>, a global, non-profit organisation whose main purpose is to facilitate and promote the introduction of policies, methods and tools to speed up the shift toward a sustainable social built environment globally.  <br /><br />The application work has been coordinated by Izabela Kurkowska (principal author of the application) and conducted in collaboration with Holger Wallbaum, Liane Thuvander, Paula Femenias, Mats Rydehell and Henriette Söderberg from Chalmers, Kristina Mjörnell from <a href="">RISE </a>and Evdoxia Kouraki and Mats Bergh from <a href="">Johanneberg Science Park</a> with support from Anna Hylander from <a href="">Gothenburg Convention Bureau</a>.<br />  <br />The programme committee for the conference will be chaired by Holger Wallbaum and Kristina Mjörnell. <br /><br /><a href="">Previous conferences <br /></a> <br />Contact for questions Evdoxia Kouraki, <a href=""> </a> <br /><a href="">Johanneberg Science Park</a><br /><br /><p></p>Mon, 08 May 2017 13:00:00 +0200 Area of Advance Workshop on Smart Cities initiated by Building Futures<p><b>​On March 8th 2017 AoA directors and profile leads from Building Futures, Energy, Transport and ICT came together to discuss the concept &quot;Smart City&quot; and identify challenges which can be tackled by joint research initiatives at Chalmers.</b></p>​Smart City has been one of the buzzwords that gained a lot of attention in recent years, yet there is little consensus about what a Smart City actually is or should be. The Area of Advance (AoA) Building Futures began a mapping process in November 2016 to gather information about the concept and systematically map related research activities at Chalmers. On March 8th 2017 AoA directors and profile leads from Building Futures, Energy, Transport and ICT came together to discuss the concept and identify challenges which can be tackled by joint research initiatives at Chalmers.<br /><br />Today, over 50 % of the world’s population live in cities, a proportion that the United Nations (U.N.) expects to increase to 66 % in 2050. The main question here is how functionality and resilience in growing cities can be assured? To many the answer seems to be “by making them smarter”. But how exactly do we make it happen? What technologies are needed and which city dimensions are affected? And finally, how can Chalmers’ Areas of Advance contribute to addressing this important challenge? <br /><br />The purpose of the mapping process initiated by Building Futures in November was to find answers to the above questions and to identify a structured way to utilize the concept of Smart Cities at Chalmers. AoA Building Futures director Henriette Söderberg explains that “often researchers are not aware of the fact that their projects directly contribute to the wide domain of Smart Cities. Our goal is to make the Smart City debate tangible for our researchers.”<br /><br />After laying the groundwork through literature review, several interviews with stakeholders from research, industry and the public sector were conducted. With respect to the <a href="/en/areas-of-advance/Pages/default.aspx">challenge-driven character of the Areas of Advance</a> 144 different Smart City challenges in 9 dimensions were collected and visualized on a large map. <br /><br />The Smart City challenge map was the point of departure for the AoAs workshop held on the 8th of March 2017. As a result of the workshop, five possible fields of action for the Areas of Advance were identified:<br /><br /><ul><li>Cyber security</li> <li>Circular economy</li> <li>Multimodal transport</li> <li>Virtual cities</li> <li>New urban planning</li></ul> <br />In the weeks to come, further strategic discussions within the Areas of Advance will take place and concrete next steps on how to anchor the Smart City topic at Chalmers will be taken. <br /><br /><img src="/en/areas-of-advance/buildingfutures/news/Documents/Workshop%208%20mars%202.jpg" alt="Workshop 8 mars 2.jpg" style="margin:5px" /><br /><br /><br />Fri, 31 Mar 2017 17:00:00 +0200 ballast material for roads for reduced environmental impact<p><b>​In a research project in the framework of the Building Futures and Production Areas of Advance, researchers at several Chalmers departments  collaborated with the Fraunhofer-Chalmers Centre for Industrial Mathematics (FCC) and NCC to develop and use simulation technology to study key processes in handling ballast materials for road construction.</b></p>​<strong>How can simulating ballast materials in roads reduce environmental impact and societal costs?</strong><br />Swedish roads are and will remain for the foreseeable future the core of Swedish infrastructure. Normally, roads are built of several bound and unbound layers of aggregate, which are subject to requirements regarding desired functionality, lifespan and surrounding soil types. Previous research at Chalmers and other universities studied ballast material as a system of particles compacted to a bed with specific properties. These properties can be adjusted by changing the character of the aggregate material and how compaction is done, but it is extremely difficult to experimentally determine how individual particles move or otherwise contribute to the rigidity of the ballast bed. Thus, the research has been limited to what is physically measurable.<br /><br /><img src="/en/areas-of-advance/buildingfutures/news/Documents/Johannes_Fredrik.jpg" alt="Johannes_Fredrik.jpg" class="chalmersPosition-FloatRight" style="margin:5px" />In an interdisciplinary research project in the framework of the Building Futures and Production Areas of Advance, researchers at <span>the Chalmers departments of Product and Production Development, Mathematical Sciences and <span></span>Civil and Environmental Engineering<span style="display:inline-block">  collaborated with  </span></span>the Fraunhofer-Chalmers Centre for Industrial Mathematics (FCC) and NCC to develop and use a simulation technology called Discrete Element Modelling (DEM) to study key processes in handling ballast materials for road construction. Loading and unloading from trucks was one process step studied, and preliminary results show that significant segregation effects occur during unloading. In addition, the study simulated the compaction of the ballast bed and preliminary results show that when comparing two cases with the upper and lower limit values for the particle size distribution, the resulting rigidity of the bed differs by a factor of two in the first compaction cycle. If the rigidity of the road body varies, it can lead to fatigue fractures and reduced lifespan, resulting in expensive maintenance measures. (Pictured left to right from above, Johannes Quist PPU, Fredrik Edelvik, FCC)<br /><br /><strong>What is the next step with this simulation technology?</strong><br />The project plans to go into its second phase, in which the entire process from loading, hauling, unloading, spreading and compacting will be studied as a process chain. If the sources of variation can be identified throughout the process chain, we hope that these insights can lead to measures to reduce the effects of variation, and eventually lead to roads with a longer lifespan and higher quality.<br /><br /><img src="/en/areas-of-advance/buildingfutures/news/Documents/bumperWithStones_690x330.jpg" alt="bumperWithStones_690x330.jpg" style="margin:5px" /><br /><br />Thu, 23 Mar 2017 17:00:00 +0100
