A user-centred approach to design Transport Interchange Hubs (TIH): A discussion illustrated by a case study in the Russian Arctic

This paper proposes a user-centred approach to design Transport In-terchange Hubs (TIH). It is based on a literature review of existing information related to TIHs outside the domain of transport engineering, so the focus is on the building and the usage of it by its main customers: the travellers. A literature review is used to extract high level information on travellers’ needs, technical and functional requirements of TIHs, constraints and design parameters. A prod-uct development approach is used to classify and combine this data so a proper set of design specifications to better address users’ needs is proposed. The method is illustrated through an example in the Russian Arctic, an area with un-der-developed transport facilities for travellers which would benefit from high-level design specifications to address complex needs, requirements and parame-ters involved in designing for extreme climate conditions. A proof of concept, using Axiomatic Design, to develop design specifications and manage constraints is applied and discussed considering major needs involved in building in the Rus-sian Arctic including how different types of simulation tools, essential to assess performance of complex buildings, can be integrated in the early stages of the design workflow. Robust specifications, despite being part of parametric design methods, are underexplored in the architecture design domain, meaning this work can contribute to further research in how to define common design targets and objectives for different stakeholders as well as to manage the collaborative work of consultants involved in designing complex buildings

Northern Eurasia Future Initiative (NEFI): facing the challenges and pathways of global change in the 21st century

During the past several decades, the Earth system has changed significantly, especially across Northern Eurasia. Changes in the socio-economic conditions of the larger countries in the region have also resulted in a variety of regional environmental changes that can have global consequences. The Northern Eurasia Future Initiative (NEFI) has been designed as an essential continuation of the Northern Eurasia Earth Science Partnership Initiative (NEESPI), which was launched in 2004. NEESPI sought to elucidate all aspects of ongoing environmental change, to inform societies and, thus, to better prepare societies for future developments. A key principle of NEFI is that these developments must now be secured through science-based strategies co-designed with regional decision makers to lead their societies to prosperity in the face of environmental and institutional challenges. NEESPI scientific research, data, and models have created a solid knowledge base to support the NEFI program. This paper presents the NEFI research vision consensus based on that knowledge. It provides the reader with samples of recent accomplishments in regional studies and formulates new NEFI science questions. To address these questions, nine research foci are identified and their selections are briefly justified. These foci include: warming of the Arctic; changing frequency, pattern, and intensity of extreme and inclement environmental conditions; retreat of the cryosphere; changes in terrestrial water cycles; changes in the biosphere; pressures on land-use; changes in infrastructure; societal actions in response to environmental change; and quantification of Northern Eurasia's role in the global Earth system. Powerful feedbacks between the Earth and human systems in Northern Eurasia (e.g., mega-fires, droughts, depletion of the cryosphere essential for water supply, retreat of sea ice) result from past and current human activities (e.g., large scale water withdrawals, land use and governance change) and potentially restrict or provide new opportunities for future human activities. Therefore, we propose that Integrated Assessment Models are needed as the final stage of global change assessment. The overarching goal of this NEFI modeling effort will enable evaluation of economic decisions in response to changing environmental conditions and justification of mitigation and adaptation efforts
