This paper studied the concept of the habitability of buildings as a sustainability factor in the living environment, particularly in the city of Bogotá. The habitability factor stems from the relationship between human beings, the cultural dimension and the environment. Thus, we can say that the habitability factor is an important element in the building design process. Currently in Bogotá there are buildings that do not meet the requirements of the population. In Bogotá only 40% of buildings are of a good quality and a great number of newly produced buildings have made for lower quality living spaces. Consequently, it is important to give an adequate response to these kinds of demands. For thase reasons, this study created a model to evaluate the habitability factor of buildings. This model gives some guidelines for designing sustainable buildings and implementing stategies to design a better urban habitat. Finally, the Habitability model was tested as a pilot in the Primero de Mayo neighbourhood, which is located in the fourth district of Bogotá. The neighbourhood was classified as a cultural heritage site by city hall.
Acidification, as a form of soil degradation is a process that leads to permanent reduction in the quality of soil as the most important natural resource. The process of soil acidification, which in the first place implies a reduction in soil pH, can be caused by natural processes, but also considerably accelerated by the anthropogenic influence of excessive S and N emissions, uncontrolled deforestation, and intensive agricultural processes. Critical loads, i.e. the upper limit of harmful depositions (primarily of S and N) which will not cause damages to the ecosystem, were determined in Europe under the auspices of the Executive Committee of the CLRTAP in 1980. These values represent the basic indicators of ecosystem stability to the process of acidification. This paper defines the status of acidification for the period up to 2100 in relation to the long term critical and target loading of soil with S and N on the territory of Krupanj municipality by applying the VSD model. The Inverse Distance Weighting (IDW) geostatistic module was used as the interpolation method. Land management, particularly in areas susceptible to acidification, needs to be focused on well-balanced agriculture and use of crops/seedlings to achieve the optimum land use and sustainable productivity for the projected 100-year period.
This article aims to evaluate the potential application of prefabricated panels in energy retrofit of facades in the Portuguese building stock. The fundamentals of this study were part of Annex 50, which was an international ECBCS IEA project, with the purpose of developing an innovative concept of building renovation for the most representative buildings based on prefabricated systems. To analyze the potential application of energy retrofit using prefabricated panels, was important to know the reality of the existing building stock and its morphology. To know the reality of the building stock, an analysis was done based on the existing statistical data and to find the most representative residential buildings, target of the study, three criteria were defined: buildings built before 1990, with 2 to 6 floors and with renovation needs in the exterior envelope. In the absence of statistical information about buildings morphology, a research work was done in the field. During the collection of data a methodology was developed in which each opening was classified according to a code with three parameters. In the end of the classification, 29 final codes were achieved and was verified that three types of panels have a higher probability of being applied.
Poland is now faced with the task of developing a long-term energy policy for decades to come, a strategy capable of reconciling the security of power supplies as well as effective economic processes, ensuring adequate standards of environmental protection. The process in which fossil fuels are converted into energy carriers of choice is accompanied by the emission of various gas substances which escape into the environment. Later on, those substances accumulate in the atmosphere as greenhouse gases affecting the Earth’s radiation balance – the greenhouse effect. Upsetting the balance between emission levels of those gases and the capacity to convert them in the atmosphere is the reason for climate changes. Sustainable development indices constitute a monitoring tool which makes it possible to create a statistical image of a country from the perspective of a new development paradigm. The most important feature of this index is the capability of comparing values, enabling to determine the position of a given object with reference to other objects. The article analyses 8 indexes of sustainable development in terms of using biomass for power generation purposes. The analysis was performed to include three social order indices, two economic indices and one environmental order index. It was concluded that the use of biomass in power generation can reduce the emission of greenhouse gasses significantly at several stages: the emission can be eliminated from the biological process of biomass conversion, storage and it can also be reduced during transportation.
One of the current challenges in transport is e-mobility, understood as electromobility, ecomobility and mobility economics. E-mobility is nowadays a key focus area of socio-technical change, in terms of attention from policy makers as well as from industry and the public. The societal challenges ahead, in particular climate change put increasing pressure on the current mobility system, due to its tremendous environmental impact. Furthermore e-mobility is seen as major economic opportunity for the automotive industry. In this context, based on the available literature and documents and practical solutions implemented already in cities and agglomerations, the paper discusses the fundamental challenges that cities are to face in the context of the current megatrends. This process will engage diff erent stakeholders in order to make this concept become a reality.
The article shows the need to take into account the principles of sustainable development in the field of the revitalization of space, and point out green roofs as a tool in this process. It is presented in the light of the green city concept, and the criteria of the European Green City Index. The article shows the ecological, social and economic benefits of green roofs (starting from the retrieval of green areas in the urbanized space, the reduction of heat island effects, up to the integration function of green roofs), which is illustrated by a few case studies of applying green roofs within revitalization projects. The article indicates also legal incentives, as well as programs directed to the development of green roofs around the world, pointing out a range of factors to consider also for Polish cities.
It is contended that, in essence, climate policy is sustainable development policy, given that it postulates the use of renewable resources, and an increase in the effectiveness of use of non-renewable ones. Furthermore, it serves the security of future generations more than present ones; for while unfavourable impacts of climate change are already making their presence felt, truly negative consequences of considerable signifi cance are likely to be more of a matter for the second half of the present century. This is why, in analysing the evolution of the approach to climate policy through the late 20th century and into the 21st, it is also possible to appraise changes in the approach to the sustainable-development concept. This article has therefore sought to offer the author’s analysis of how the approach to sustainable development has evolved, by reference to Poland’s climate policy from 1988 through to 2016. As this is done, an attempt is also made to identify the conditioning that has decided upon and will go on determining the shape of national policy in this domain. Climate policy in Poland has been developing since the early 1990s. At the outset, it was not a source of controversy, with the consequence that the country rather rapidly signed up to and then ratifi ed the Kyoto Protocol to the UN Framework Convention on Climate Change. However, as early as in the late 1990s, reservations began to be expressed, to the effect that actions to protect the climate might pose a threat to Poland’s economy. A key turning point as regards the approach came with the growing dispute over the EU 2020 Climate and Energy Package. It was also at this time that a thesis began to take shape, holding that the goals of climate policy where at best unfavourable and at worst dangerous for Poland. This approach in fact held sway in successive years, leaving this country’s cooperation with the EU over this matter severely hindered. The main reason for this change of approach to climate policy can be considered to lie in the politicisation thereof, and hence the increasing dominance of the short-term interests of the Polish political elite over either the public interest or the security of future generations.
In 1981, Polish canoeists (members of the Bystrze Academic Travel Club) made the first journey along the waters of the River Colca in the section located in Arequipa Province (Peru), along which the waters flow in a deep canyon. Information on this sporting achievement – and a description of the Canyon and its surrounding area filled the Peruvian press and tourist publications around the world, ensuring that the Colca Canyon became one of the most important goals for tourists anywhere in Peru from that time on. However, mass infl uxes of tourists, noisy trips, the development of hotel infrastructure and other items required in tourism have generated permanent change in the character of the Colca Valley, and done much to influence the lives of its inhabitants.
The development of both the town and the administrative commune of Zielona Góra is characterised by a progressive process of uncontrolled linear urban development, so called urban sprawl. This phenomenon has existed in the town for a long time, but because of the fast development in the 21st century it is now even stronger and has an unfavourable impact on the dwellers’ comfort, communication and accessibility. The directions of changes adopted for spatial development in the current strategic documents of the new town (since 1 January 2015), which came into being as a result of the merger between the town and the rural commune of Zielona Góra, do not guarantee that the unfavourable processes will be stopped. The process of uncontrolled urban development results in the growth of dense urban structures along the roads and communication routes. This prevents an optimum use of areas located further away or behind the existing infrastructure and causes dead zones to appear, where there are no communications or infrastructure. With each new investment (a plot of land with access to a public road, as specified by the regulations) the distance between recreational areas (green spaces) and the town centre increases. The deteriorating dwelling conditions are a direct result of the unfavourable phenomenon of urban sprawl.
The article aims at determining the place and role of environmental issues in spatial management in relation to scientific achievements of Professor Zbyszko Chojnicki. A few words about the professor’s approach to the issue of using the natural environment in spatial management provide a starting point for the ongoing discussion. Next, attention is paid to the place of environmental issues in the interactive model and in the conception of the territorial social system by Professor Chojnicki. This concerns first of all the distinction and description of these elements of the natural environment and environmental relations which are identified in these systemic aspects. In the following part of the article, the analysis of environmental issues is carried out as the subject of interest of spatial management in the context of scientific achievements of Professor Chojnicki in this field. The paper concludes with a short presentation of studies inspired by works of Professor Chojnicki on sustainable development of cities.
As a result of introduction of the Directive 2010/31/EU of the European Parliament and of the Council of 19 May 2010 on the energy performance of buildings, all of the EU member states are obliged to introduce legal regulations for energy performance of all newly constructed buildings. The key aim is to achieve close to zero energy use starting from the year 2021. Estimating effectiveness of the actions and the new possibilities requires an analysis of the multiple criteria. They comprise both the current conditions as well as the changes that have occurred in the recent years due to new legislation, the eff ects of the subsidies and the development of the housing stock. This paper presents a broad overview and diagnosis of current situation. The development of the energy-efficient and passive housing in Poland is considered in the context of financial incentives, availability of design knowledge and building technology as well as the role of the green building certification.
Regeneration – an integrated process of activities undertaken in the spatial, social and economic dimensions – should lead to the improvement of the living conditions of inhabitants of degraded urban areas. The European Union in 2007- 2013 allocated financial resources for this purpose in the form of JESSICA initiative which is based on financial engineering mechanism. Experiences gained so far allow conclusions to be drawn that JESSICA is a highly fi nancially-effi cient instrument but, however, not always delivers the desired outcomes in the spatial and social sphere. The scope of projects often is limited to infrastructural investments and does not reflect the complexity of regeneration process. In the article the authors analyse experiences of the five Polish regions with the use of JESSICA, point out main problems and formulate recommendations for sustainable urban policy.
The social, economic and environmental zone is constantly changing in terms of factors aimed at improving the quality of life, economic and technological development of the city while at the same time rational use of resources of the natural environment. Change as a dynamic factor is an impulse for creating new behaviors of residents and interactions between them and public and private sector entities. The article attempts to systematize selected contemporary concepts shaping the city, emphasizing the coherence of their assumptions and the scope of the issues discussed. Looking for features that characterize the city, which balance the needs and expectations of its users.
Natural gas plays a significant role in the energy structure of many world economies. Many of them are highly dependent on domestic resources exploitation, other on its deliveries from non-domestic directions. In Poland its importance was relatively low, but in recent years we can observe an increase of interest in this raw material. The aim of the paper is to present the role of natural gas as a primary energy carrier and to determine its impact on the sustainable development and energy security of Poland. The role of gas in the European Union restrictions and development of the domestic economy is also a point. Theoretical deliberations are focused on the most important features of the Polish natural gas market. The article presents the most important national regulations concerning the development of the gas sector in Poland. The amount of natural gas resources are shown as well as indigenous production of the fuel and imports, including the directions from which natural gas is imported. Both political and geographical aspects of the directions of natural gas acquisition are discussed. The level and potential abilities of the diversification of the natural gas supply are discussed. The importance of gas storages in underground gas repositories is underlined. The authors point to the increase in the diversification of raw materials in the structure of electricity, heat production and the transition to pro-ecological fuels.
Industry 4.0 and the associated idea of society 4.0 pose specific challenges for the concept of sustainable development. These challenges relate, inter alia, to responsibility, in which the changes to date have overall entailed: • a transition from ex post responsibility to ex ante responsibility (H. Jonas); • a transition from individual responsibility to corporate social responsibility. In the context of society 4.0 there is a need for shared responsibility. The problem of justice and therefore the implementation of sustainable development not only becomes an open problem, but also requires constant updating and specifi c optimisation.
This article takes up the matter of contemporary threats to cities and urbanity, setting the problems cities face today against the background of the two categories of the resilient city and the city developing sustainably. The author describes and presents the evolution of the sustainable development concept as such, as well as the generational change in priorities that has taken place where the development of urbanised areas is concerned, given the way the concept has undergone a certain devaluation, in the light of its failure to achieve fulfi lment. The challenges cities face today require multi-faceted activity, in respect of increased inclusivity, robustness and resilience, and flexibility. This leaves today’s idea of the resilient city embracing old elements of the sustainable city, but also augmenting them in various ways.
The paper presents an analysis of the sustainable development of electricity generation sources in the National Power System (NPS). The criteria to be met by sustainable power systems were determined. The paper delineates the power balance of centrally dispatched power generation units (CDPGU), which is required for the secure work of the NPS until 2035. 19 prospective electricity generation technologies were defined. They were divided into the following three groups: system power plants, large and medium combined heat and power (CHP) plants, as well as small power plants and CHP plants (distributed sources). The quantities to characterize the energy effectiveness and CO2 emission of the energy generation technologies analyzed were determined. The unit electricity generation costs, discounted for 2018, including the costs of CO2 emission allowance, were determined for the particular technologies. The roadmap of the sustainable development of the generation sources in the NPS between 2020 and 2035 was proposed. The results of the calculations and analyses were presented in tables and figure
Integration of transport subsystems in transfer nodes of public transport in Poznań based on city railway stations, Poznań, being one of the strongest urban centers in the country, has a significant zone of impact (functional area). A natural consequence of this development model are significant communication issues caused by dynamic development of the suburban area. The solution of those issues is assumed to be basing the public communication system on a railway junction and, on its basis, creating the Poznań Metropolitan Railway. However, to ensure efficient functioning of such a system the need arises to integrate it with other systems of transport using transfer nodes. The aim of this article is to illustrate the potential of creating a polycentric system of multi-modal transfer nodes, based on existing city railway stations (district stations). The study focuses on the perspective of the passenger and the primary research method is the in-depth interview. This enabled to learn the opinion and identify the needs of passengers who use the facilities which are the subject of this study. The study also concentrated on analyzing thee communication behaviors of passengers and analyzing thee functioning of city stations themselves. Additionally, information was also acquired regarding the approximate destination of the passengers’ travel, which further allowed to specify the hypothetical impact range of individual city stations. Results of the study allowed to develop a range of recommendations intended to optimize the functioning of selected city railway stations, from a technical, as well as organization and management perspective. They have the potential to become a basis for developing a concept of sustainable public transport with a metropolitan reach.
The article presents the issues related to ecological security of the Baltic Sea. The issue was taken from the perspective of Poland as one of the Baltic States, and also as a Member State of the European Union. The authors discussed the mechanisms and legal instruments which are crucial for the ecological security of the Baltic Sea (i.e. Helsinki Convention of 1974, or Agenda 21 for the Baltic Sea Region “Baltic 21”). The importance of cross-border cooperation has also been emphasized as an essential element of the security policy in the Baltic Sea area. The article also indicated threats to the protection of Baltic waters, among others, eutrophication.
The aim of this paper is to discuss energy certification systems and multi-criteria certification schemes – both the assessment tools focusing on the level of the single building and on the urban level. The role of certification systems and the emerging technologies as a means of reducing energy consumption and achieving the high energy quality of the built environment is investigated.
This paper examines the conservation master plan prepared for in Beyoglu, Istanbul’s Galata Persembe Bazaar waterfront and its Genoese and Ottoman port heritage. This paper initially contains an analytical perspective. This perspective informs the analyses of the evolution of planning process on the conservation of the port heritage. The results of relations between port heritage and conservation planning works have come up for discussion. Spatial interventions on the Persembe Bazaar waterfront began in the 1980s by removing industrial and commercial buildings in the area. These interventions, made in the framework of wiping away the Halic (Golden Horn) waterfront created pressure for urban regeneration in areas with historical and cultural heritage assets like Persembe Bazaar. Major projects such as Galataport and Halicport on the waterfronts of the Halic and the Bosphorus have increased this pressure. Huge functional transformations on the waterfront are desired along with the Persembe Bazaar Conservation Master Plan, which conforms neither to the content nor the context of general conservation principles or Turkey’s conservation legislation. Its content includes no interventions compatible with the theme of “living in harbour cities” and should thus be criticized. The conservation of the tangible and intangible heritage of historical port features, the preservation and development of the service sector and trade in the area requires adopting a holistic understanding of conservation and taking historical features into account. Such an important port heritage site should not be seen as having only touristic functions. It should emphasize more local features for their daily use of local residents and businesses.
The article aims to present the scope of influence of Integrated Territorial Investments (ITI) on the sustainable development of urban functional areas (FUAs) in Poland. Against the background of the general principles of the implementation of the both instruments, practical aspects of the implementation of ITI in FUAs have been presented. Detailed analyses in the financial and spatial aspect were carried out using the Sustainable Development Indicators (SDI). These provided the basis for presenting the practical aspect of supporting the sustainable development of urban functional areas in the EU Cohesion Policy 2014–2020.
Axiological chaos and unsustainable man’s acting in a contemporary world has led him to a total confusion. He constantly acts toward environmental and cultural degradation. Also in social dimension a permanent and “general” crisis dominates. The crisis is rooted on multi-category stratification and based on post-truth models of interpersonal communication in traditional and virtual realities. Neoliberal model of economical conquest, in turn, effects unsustainability in economic sphere. Thus, in common reception – for the most people in the world – such situation has become unbearable. So, it is the educators’ duty to look for – with the intention to put into practise – such concepts and pedagogies, which could prepare the whole global society to real – not declaratory false – co-creation of its life in the world, understood as an actual and common home. Taking such perspective, the theory of Argentinian philosopher – Ernesto Laclau becomes an interesting proposition. The time of mono-dimensional – protestant and neoliberal – interpretation of values comes to the end. Now the time has come to accept the equality of different – having their roots in various cultures – value understanding. Possibility of local and particular interpretation of values – along with maintaining the rule of common good – gives the chance to update the education according to real, thus multidimensional humanistic ideal. Such a standpoint presents a way to cure/reform intercultural education, which nowadays is at an impasse. Mainly it uses stiff schemes and repeated patterns, so it has become imitative and conservative. In its contemporary formula intercultural education is not able to respond to present challenges of multicultural and global society. The need to implant into its structure the concept of sustainable development emerges as a must.
