The Directive 2010/31/EU on the energy performance of buildings has introduced the standard of “nearly zero-energy buildings” (NZEBs). European requirements place the obligation to reduce energy consumption on all European Union Member States, particularly in sectors with significant energy consumption indicators. Construction is one such sector, as it is responsible for around 40% of overall energy consumption. Apart from a building’s mass and its material and installation solutions, its energy consumption is also affected by its placement relative to other buildings. A proper urban layout can also lead to a reduction in project development and occupancy costs. The goal of this article is to present a method of optimising single-family house complexes that takes elements such as direct construction costs, construction site organisation, urban layout and occupancy costs into consideration in the context of sustainability. Its authors have analysed different proposals of the placement of 40 NZEBs relative to each other and have carried out a multi-criteria analysis of the complex, determining optimal solutions that are compliant with the precepts of sustainability. The results indicated that the layout composed of semi-detached houses scored the highest among the proposed layouts under the parameter weights set by the developer. This layout also scored the highest when parameter weights were uniformly distributed during a test simulation.

Extending the life cycle of heritage buildings through their adaptive reuse can ensure their survival and is concordant with the policy of sustainable development. Selecting a new form of use for heritage building adaptive reuse projects is a multidimensional process that can be significantly aided by multi-criteria decision-making approaches. In this paper, the authors have proposed a hybrid form of structural analysis, which is a formulation of a multi-criteria approach to the analysis of complementary forms of use for a complex of historical buildings, to be used during the early planning stages of adaptive reuse projects for heritage building complexes. The approach has been demonstrated on the example of the Boyen Fortress complex in Giżycko, Poland. The outcome of the analysis indicated that the highest share of floor space to be adapted should be dedicated to exhibition spaces, which is justified concerning cultural heritage benefits. This approach can be of significant aid to decision-makers during adaptive reuse project planning phases, thereby facilitating the continued survival of heritage sites.

This paper presents the geography of the historic central district of Kraków, Poland before, during and after the first wave of the 2020 pandemic. It describes how the disneyfied main part of the UNESCO heritage site of universal values turned into a ghost town as functional changes were turning into physical ones amid restrictions. From the results of pre-pandemic processes (that, as we argue, turned the city into its disneyfied version), to the lockdown (that later revealed itself to be but the first one in a row), to the post-lockdown recovery, these changes are presented in modified figure-ground diagrams with accessibility being defined by both tangible and intangible properties. The results are set against the background of the city’s current policies regarding economic recovery, mobility and accessibility to urban green areas. As an attempt to address the present vulnerability of the once resilient historic city centres—of which Kraków Old Town is a luminous example—this paper tends to be a voice in the debate on the post-2020 planning and the strategies we will need to face the subsequent waves of this, or other, pandemics as well as consequences of climate change.

The numerous effects of climate change on the urban environment over the past decades have urged many planning professionals to implement the United Nations’ Sustainable Development Goals (SDGs). Higher education institutions (HEIs) bear particular responsibility for sustainability-aware designers able to implement specific measures in this field. This paper presents a typology of design solutions for urban contexts intended to implement Sustainable Development Goal 11, which refers to making cities and human settlements inclusive, safe, resilient, and sustainable, which can be included in university curricula. The study presents a comprehensive source base of possible interpretations of sustainability guidelines in architectural, landscape, and transport solution design and can be used to guide and assess projects in these fields. Solutions identified and analyzed were grouped into four dimensions related to sustainability aspects (accessibility, ecology, functionality, and identity). The framework proposed was developed based on the teaching experience of thesis design projects and practice-based workshop course projects featured in the curricula of first and second cycle Architecture, Landscape Architecture, and Transport programs taught at the Cracow University of Technology, Poland. The projects were prepared as a part of workshop-based public consultations for a real-world project—the construction of a transport hub in Hrubieszów, Poland. The most complex implementation of various individual sustainable design solutions was linked to the interdisciplinarity of the design team and the broadest public participation spectrum.

Historic buildings make up a significant proportion of the existing building stock. Most are characterised by poor technical condition and high energy demand. In Poland, many historic buildings are still in use today, but it is also common to find these buildings subjected to adaptive reuse. Adaptive reuse, often combined with modernisation, is problematic, especially in terms of finding a use that is optimal in the light of use-specific decision criteria. In previous studies, the authors used and developed the potential for the modelling and structural analysis of decision-making problems for the selection of new uses for historic buildings. In this paper, we present a test of this methodology on a Polish historic building. To further the application of our approach in sustainability-focused contexts, we performed the analysis using criteria focused on environmental and energy performance, in addition to other established criteria. In our study, the highest ranking use was a kindergarten, which scored 18% higher than the second-ranked alternative and over 90% higher than the lowest-ranked alternative.
