mySMARTLife project aims at the development of an Urban Transformation Strategy to support cities in the definition of transition models, as a suitable path to reach high level of excellence in its development process, addressing the main city challenges and progressing to the smart people and smart economy concepts. The main instrument to achieve this very ambitious strategy will be the definition of the Advanced Urban Planning, consisting of an integrated approach of the planned city interventions on the basis of a rigorous impact assessment, an active citizen engagement in the decision-making process and a structured business approach, from the city business model perspective, to the economic framework for big companies and local SMEs and Start-Ups. Nantes (France), Hamburg (Germany) and Helsinki (Finland) are the lighthouse cities and Varna (Bulgaria), Bydgoszcz (Poland), Rijeka (Croatia) and Palencia (Spain) the followers. All of them will be involved in the overall project development assuming different and complementary roles. Energy and Climate mitigation plans in the lighthouse cities are completely compliant with the objectives of Covenant of Mayors initiative, as it is reflected; first regarding the early participation of the cities in Covenant of Mayors and second, considering the ambition of their SEAPs, that were submitted, evaluated, approved and are monitored by Covenant of Mayors. Aligned with these objectives, the commitment of the lighthouses is the deployment of a big set of large scale interventions and at least two years of data collection to make a depth analysis of the results, calculating standard KPIs, evaluating the associated impacts and disseminating the results. Followers will be very close to this demonstration, collaborating in the definition and deployment, analysing the problem from the point of view of their own city challenges and extracting knowledge, best practices and lessons learnt for a further replication.

The overall objective is to minimise the leakage of materials from the linear economy and work towards a circular economy. Specific objectives are to: Engage cities, enterprises, citizens and academia in 16 participatory value chain based partnerships to create and develop eco-innovative solutions together. Develop 10 viable end-markets by demonstrating new applications for plastic waste, metals (EEE devices), biowaste and wood waste. Develop a governance model for cities based on value chain based partnerships. Develop decision support tools and assess the actual impact by use of Big Data. Ensure replication through the FORCE Academy aiming at enterprises, citizens and policy makers. The eco-innovative solutions will be demonstrated across four cities (Copenhagen, Hamburg, Lisbon and Genoa) and using the four materials: Flexible plastics: Recycling and upgrade of 5,000 tonnes of flexible plastic from enterprises and private households will enable virgin material substitution, corresponding to preventing emissions of 12,500 tonnes of CO2. Metals: Citizens will be mobilised to reclaim an additional 2 kg/capita of WEEE (app. 3,600 tonnes). A communication campaign will reach 100,000 citizens and support at least five SMEs that repair damaged EEE devices so that 10-20% of the collected WEEE can be redistributed. Wood waste: additional 12,000 tonnes wood waste from urban and mountain areas will be collected. 8-10,000 tonnes of brushwood will be used for compost production, and 14-16,000 tonnes will be processed into wood particles. Biowaste: around 7,000 tonnes of biowaste from the municipal mixed waste stream will be recovered: 3,000 tonnes coming from restaurants and hotels, and 4,000 tonnes coming from households. The partnerships will result in the creation of viable eco-innovative market solutions, exploited by the partners. Replication in other cities will be incentivised thus ensuring competitiveness of European Circular Economy and green growth.

A shift towards a more circular economy is crucial to achieve more sustainable and inclusive growth. Our objective is to provide local and regional authorities with an innovative transdisciplinary open source geodesign decision support environment (GDSE) developed and implemented in living labs in six metropolitan areas. The GDSE allows creating integrated, place-based eco-innovative spatial development strategies aiming at a quantitative reduction of waste flows in the strategic interface of peri-urban areas. These strategies will promote the use of waste as a resource, thus support the on-going initiatives of the EC towards establishing a strong circular economy. The identification of such eco-innovative strategies will be based on the integration of life cycle thinking and geodesign to operationalise urban metabolism. Our approach differs from previous UM as we introduce a reversed material flow accounting to collect data accurate and detailed enough for the design of a variety of solutions to place-based challenges. The developed impact and decision models allow quantification and validation of alternative solution paths and therefore promote sustainable urban development built on near-field synergies between the built and natural environments. This will be achieved by quantifying and tracking essential resource flows, mapping and quantification of negative and positive effects of present and future resource flows, and the determination of a set of indicators to inform decision makers concerning the optimization of (re-)use of resources. The GDSE will be open source. With a budget of 5 million, REPAiR funds a consortium rich in experience in waste and resource management, spatial decision support, territorial governance, spatial planning and urban design, and has deep knowledge of the 6 case study areas. REPAiR is supported by a user board, of key stakeholders for the development of CE as well as local authorities, who are heavily involved in the GDSE testing.

The building sector has a significant share in a county's total greenhouse gas emissions, and as a reaction to the Kyoto commitment most countries are constantly adjusting building energy requirements in order to reduce greenhouse gas emissions and mitigate the climate change. While it is easier to set standards for the building fabric and for technical systems, the impact of occupants on comfort and energy performance in buildings has proven to be important, but is a lot harder to account for. This paper therefore aims to investigate the magnitude of influence of occupants in relation to climate and architectural design on thermal comfort and CO2 emissions in offices in different climate zones of the world. The aim is to identify typical patterns and key parameters for optimisation.For this purpose, a parametric study for a typical cellular office room has been conducted using the simulation software EnergyPlus. Two different occupant scenarios are each compared with three different architectural design variations and modelled in the context of three different locations for the IPCC climate change scenario A2 for 2030. The evaluation of the results is focused on two different modes of operation. For natural ventilation adaptive thermal comfort according to ASHRAE Standard 55 has been evaluated, and for mixed mode operation final energy consumption and resulting CO2 emissions. The results indicate a first approach to estimate comfort levels based on climatic data, architectural design priorities and occupancy. Additionally, warmer climates seem to have larger optimisation potential for comfort and energy performance in offices compared to colder climates. © 2013 Elsevier Ltd.

Vulnerability studies need to consider changes in the ecological and the social system as well as their interactions. Yet, the link between ecosystem services and the wellbeing of different social groups represents a deficit in research. The presented case study attempts to create a deepened understanding of the social-ecological system as a basis for vulnerability assessment. For this purpose, participatory mapping of cultural ecosystem services (CES) and perceived vulnerability in the urban region of Rostock (Germany) were conducted. A comprehensive approach was developed including the spatial distribution of CES in the urban region, the interrelations between the supply and demand of CES (considering different social factors and the spatial link), as well as an exemplary vulnerability assessment. The case study showed that an application of the participatory mapping approach is valuable in a wide urban region. The evaluation of the link between population wellbeing and CES suggested no differences according to social factors. Concerning the spatial link, different critical distances for individual CES were found. An integrated map of supply and demand was developed showing the supply of districts with CES area, number, and diversity. The final exemplary vulnerability assessment visualized potential changes in CES supply areas and affected districts in the urban region. © 2015 Taylor & Francis.

In room acoustics as well as in noise immission prognosis, ray tracing methods are efficient and widely used. Nevertheless, as is well recognised, these energetic methods assuming incoherent superposition fail when diffraction becomes important. The aim is to solve this main deficiency, but the energetic model shall be retained. However, since random emitted particles never pass edges exactly, analytical edge diffraction approaches may not be applied. These and other general problems of combining diffractions with the numerical methods of geometrical room acoustics are discussed in the first part of the paper. To introduce diffraction but preserve the algorithmic advantage of ray tracing, the author had proposed a sound particle diffraction model based on Heisenbergs uncertainty relation (UR) introducing the concept of a 'diffraction angle probability' and an 'edge diffraction strength' (the closer the by-pass-distance the stronger the diffraction effect'). This model, already presented in 1986, demonstrated very good agreements with the expected transfer functions of the basic reference cases of a half-infinite screen and a slit in far field. It has now for the first time been embedded in a full ray tracing program enabling also finite source and receiver distances. The results have also been compared with the exact wave-theoretical results of Svenssonts secondary edge source model. For most cases of the screen and the slit the agreements are very good (less than 1 dB). Also - not self evident - the reciprocity principle seems fulfilled. Exploiting the UR seems to be a useful approach not only for light - as has been published in the field of optical ray tracing - but also for sound. However, whether the method works also with higher order diffraction and with other structures has not yet been investigated for sound. A very difficult practical problem remains the explosion of computing time which may be solved by the re-unification -algorithm provided by Quantized Pyramidal Beam Tracing. © S. Hirzel Verlag.

Analyses of spatiotemporal data are affected by different kinds of uncertainty, and various studies have shown that their impact can be severe. This is especially true for land cover change analysis based on remotely sensed data – it has been shown that ignoring uncertainty can lead to unreliable results. Approaches are needed that incorporate information on uncertainty into the analysis. However, usable models and methods are still rare and the supposed positive effect of uncertainty information has not been extensively studied. In this contribution, we describe the development of ICchange, an interactive visual prototype for the exploratory analysis of land cover change following a geovisual analytics approach. Apart from serving as proof of concept, the prototype will be used to evaluate the role of uncertainty information during change analyses. We conducted a qualitative evaluation of the prototype using low-level tasks to test basic usability. The input from the study is used to improve the design. A special focus is placed on the visual representation of uncertainty in one of the views that did not perform satisfyingly. The prototype presented here will be used in future studies to evaluate the role of uncertainty in real-world change analysis. © 2014, © 2014 Taylor & Francis.

The aim of this paper is to study the implementation of online games to encourage public participation in urban planning. Its theoretical foundations are based on previous work in public participatory geographical information systems (PP GISs), play and games, with a special focus on serious games. Serious games aim to support learning processes in a new, more playful way. We developed the concept of playful public participation in urban planning, including playful elements such as storytelling, walking and moving, sketching, drawing, and games. A group of students designed an online serious public participatory game entitled NextCampus. The case study used in NextCampus was taken from the real-world question of a possible move of a university campus to a new location in the city of Hamburg, Germany. The development of the serious public participatory game NextCampus resulted in a physical prototype, user interface design, and a computational model of the game. The NextCampus game was tested with the help of two groups of urban planning students and presented to three external experts who provided valuable recommendations for further development. The critical comments questioned the level of complexity involved in such games. The positive comments included recognition of the potential for joy and the playfulness a game like NextCampus could evoke. © 2011 Elsevier Ltd.

In the context of an integrated pilot study between the HafenCity University Hamburg, the Jade University of Applied Sciences in Oldenburg and the Agency for Geo-Information and Surveying Hamburg the Bismarck monument in Hamburg has been scanned with the Z+F IMAGER 5006 3D laser scanning system to generate a virtual 3D model of the monument from the laser scanning data using different programs. A substantial aspect for modelling was data reduction, since the generated 3D model has to be integrated into the city model of Hamburg with the smallest possible data volume. Therefore a combination of triangle meshing and CAD turned out to be an optimal solution. Furthermore, the extent to which the modelled data can be reduced by appropriate polygon decimation, in order to derive a geometrically correct and visually attractive result (virtual 3D model), has been investigated. The geometrical quality of the model was evaluated on the basis of reference values. As well as the integration of the virtual model into the city model of Hamburg the generated virtual model was also prepared for interactive visualisations. For the entire processing of the project time management of the individual work procedures has been calculated, in order to derive statements about the economy of the project. Thus conclusions/recommendations for further projects on object recording, modelling and visualization of such historical buildings and monuments using this procedure with this technology could be provided. © 2010 Springer-Verlag Berlin Heidelberg.

Interactive maps on the internet have become frequently used means to convey spatial information to the public. However, many maps are not developed to suit a variety of users and thus lead to frustration. To user-center maps we therefore recommend to personalize them to individual users. As many parameters that can be used as a trigger for personalization are not easy to be logged on the internet, we suggest user-map interaction. Interaction can be easily tracked and gives comprehensive information about map use. Since no interpretation of user-map interaction is available it is the aim of this PhD to observe interaction, and to evaluate and interpret it. We hypothesize that there are map interaction patterns, means recurring sequences of consecutive actions which are necessary to complete a task. Our goal is to deduce parameters for personalization from these map interaction patterns. Copyright © 2012 ACM.
