  • Does rated visual landscape quality match visual features? An analysis for renewable energy landscapes
    Item type: Journal Article
    Spielhofer, Reto; Hunziker, Marcel; Kienast, Felix; et al. (2021)
    Landscape and Urban Planning
    Finding the “right” sites for developing renewable energy systems (RES) is one of the major challenges in planning strategies for energy transitions. The visibility aspects of such infrastructure are important factors that explain local opposition. Classical visibility and viewshed analyses of RES disregard people’s perceptions and estimations of new infrastructure. To address this void, we demonstrate an approach that combines rated visual landscape qualities with measured visual features. In doing so, we established visual stimuli with systematically controlled visual impact scenarios featuring the use of renewables in different landscape types. The study investigated how ratings of landscape qualities are affected by landscape changes stemming from RES. We also identified measurable visual features that might help to operationalize landscape qualities. Finally, we intended to improve the understand of how rated landscape qualities lead to preferences for different RES visual impact scenarios. Our results showed that rated coherence is strongly influenced by renewable energy infrastructure, whereas complexity ratings are affected mainly by variations in landscape types. These findings let us to conclude that the visual understanding and visual connectedness between energy systems and surrounding landscapes are core drivers of people’s visual preferences for landscapes altered with RES. Considering landscape qualities within impact assessments of RES can augment our grasp of how the visual character of a landscape changes through renewable energy infrastructure.

  • Developing a GIS-Based Visual-Acoustic 3D Simulation for Wind Farm Assessment
    Item type: Journal Article
    Manyoky, Madeleine; Wissen Hayek, Ulrike; Heutschi, Kurt; et al. (2014)
    ISPRS International Journal of Geo-Information
    Public landscape impact assessment of renewable energy installations is crucial for their acceptance. Thus, a sound assessment basis is crucial in the implementation process. For valuing landscape perception, the visual sense is the dominant human sensory component. However, the visual sense provides only partial information about our environment. Especially when it comes to wind farm assessments, noise produced by the rotating turbine blades is another major impact factor. Therefore, an integrated visual and acoustic assessment of wind farm projects is needed to allow lay people to perceive their impact adequately. This paper presents an approach of linking spatially referenced auralizations to a GIS-based virtual 3D landscape model. We demonstrate how to utilize a game engine for 3D visualization of wind parks, using geodata as a modeling basis. In particular, the controlling and recording of specific parameters in the game engine is shown in order to establish a link to the acoustical model. The resulting prototype has high potential to complement conventional tools for an improved public impact assessment of wind farms.
  • Inclusions – Landscape Narratives for Enhancing Digital Landscape Architecture Pedagogy
    Item type: Journal Article
    Fricker, Pia; Wissen Hayek, Ulrike; Monacella, Rosalea; et al. (2024)
    Journal of Digital Landscape Architecture
    With the escalating challenges of the climate crisis, we are confronted with accelerated urbanisation and environmental degradation, there is an urgent need for the transformation of our landscape and urban systems. This transformation necessitates the creation of environments that are not only equitable and resilient but also adaptive, with the capability to mend and respond adeptly toward more equitable, resilient, and adaptive environments that imbue the capacity to repair and respond to indeterminate future crises. Landscape architecture as a discipline has a pivotal role in designing alternative landscapes that have the ability to innovatively endure the uncertainties and challenges of a complex, ever evolving polycrisis set in motion by the climate crisis. The application of sophisticated analytical design tools and data from related disciplines, have the capacity to significantly enhance landscape design methodologies. Despite this potential, the integration into landscape architectural education remains sporadically imple-mented. This inconsistency highlights the imperative for a paradigm shift in landscape architectural pedagogy, that transcends the traditional digital / analogue and computational distinctions. It advocates for a design thinking approach where techniques are critically evaluated, and innovation is deemed essential in addressing the climate crisis. A re-evaluation of landscape architectural design pedagogy is necessary. Building on the discussions on future pedagogical methods at the DLA 2023 conference, an international workshop was convened to further this dialogue focusing on ‘inclusion’, ‘narratives’, and ‘co-design’ amidst the complex global challenges posed by the climate crisis. This involved analysing practice projects and design studio pedagogies guided by the question how to achieve climate respon-sive designs. This analysis explored the diverse flow of ideas, dynamics and frictions that emerge from multiple viewpoints. These critical evaluations of current theoretical and practical underpinnings helped in outlining a methodological framework for landscape design. This framework is intended to foster the creation of new landscape narratives, incorporating digital design education guidelines that underscore the urgent need for innovation and diversification of approaches within the field of landscape architec-ture. This investigative process ultimately led to the development of a set of guidelines that advocate for a significant transformation of landscape architecture education.

  • Sound ambiences consistent with visualizations of landscape types – An evaluation
    Item type: Journal Article
    Wissen Hayek, Ulrike; Endres, Laura; Spielhofer, Reto; et al. (2018)
    Journal of Digital Landscape Architecture
    Using digital landscape representations for assessing people’s perceptions of the visual landscape and their preferences for alternative options of landscape change, a high simulation quality is required. Thereby, sounds can augment people’s experiencing of the demonstrated landscape. We present an approach to establish sound ambiences and to investigate their level of perceived con-sistency with visual representations of different landscape types in a laboratory experiment. The results show that sounds expected through the visual contents and sounds anticipated by partici-pants remembering similar situations need to be reproduced. For presenting a realistic sound am-bience a mix of soundmarks and of more general ambient sounds is important. Further, the sounds’ volume and dominance are decisive for the overall consistency. It is notable that people in laboratory environments seem to not always accept the volume measured in the real landscape as appropriate. Our conclusions give advice for designing audio-visual simulations. Furthermore, we provide guidance for evaluating the consistency of audio-visual stimuli for implementation in landscape preference studies.
  • steuerBAR? Wo wollen wir "Energielandschaften" und wo nicht?

    Die vorliegende Studie befasst sich mit den Präferenzen der Schweizer Bevölkerung in Bezug auf Infrastrukturen zur Produktion erneuerbarer Energie (engl. IPRE: Wind, Photovoltaik) in charakteristischen Schweizer Landschaften. Es wurde eine repräsentative Online-Panelumfrage (n = 1063) durchgeführt, die ein visuelles Entscheidungsexperiment beinhaltete. Die Ergebnisse legen nahe, dass das Vorhandensein von Energieanlagen die wahrgenommene Landschaftsqualität in den meisten Fällen reduziert, in einigen Landschaften mehr (Berggebiete abseits von Infrastrukturen,Voralpen, Jura), in anderen weniger (siedlungsgeprägtes Flachland undentsprechende Berggebiete (Alpentäler), touristisch geprägte Berggebiete). Dasgänzliche Fehlen von Photovoltaik-Infrastrukturen wird in letzteren von der Bevölkerung sogar negativ bewertet, doch eine Kombination mit Wind-Infrastrukturen kann die Beurteilung positiv beeinflussen. Der Einbezug der Bevölkerungssicht in die Planung von IPRE wird im Hinblick auf deren Akzeptanz empfohlen. This study deals with the preferences of the Swiss population with regard to infrastructures for the production of renewable energy (IPRE: wind, photovoltaics) in characteristic Swiss landscapes. A representative online panel survey (n=1'063) was conducted, which included a discrete choice experiment. The results suggest that the presence of energy installations reduces the perceived landscape quality in most cases, in some landscapes more (abandoned mountain areas, Prealps, Jura), in others less (lowland & mountain areas (alpine valleys), tourist mountain areas). The total absence of PV infrastructures in the latter is even rated negatively by the population, whereas a combination of PV and wind infrastructures can have a positive impact on the assessment. The inclusion of the population’s perspective in the planning of IPRE is recommended with a view to its acceptance.
