Can civilisation at its current level of development afford the further wasting of all forms of energy? This is the question that forms the foundation of the entire philosophy of energy saving, and - to be more precise - of the work towards its efficient use. The greatest consumers of energy are mega-metropolises, as the amount of energy required to build them, produce all the necessary construction materials and their transport to the construction site, followed by the occupancy of the structures that have thus b...

At present, the building sector holds more than 40% of energy consumption and 36% production of greenhouse gas emissions. The whole sector of buildings uses more than 50% of the Earth's raw materials and produces approximately 50% of world waste. The current legislative standards require as much as possible energy efficient construction. The inadequate thermal performance of the buildings and are currently the biggest challenges for the sector of buildings in the European Union in the context of addressing the sus...

According to the sustainable mobility, there are many rules how to do best a moving the citizens in our cities. What is interesting that we do not have a classical ? technical rules how to reach the sustainability in transport. The big deal is coming from the NGO people, mainly. The politicians have open their arms for them and then defectively requires from professionals non-systematic solutions. In Bratislava, Capital of Slovakia, is like in other cities in Europe a huge development boom. Completely new down tow...

People spend approximately 90% of their life in the indoor environment of buildings. Indoor environment significantly influences the health, the comfort and the performance of buildings users. The long-term insufficient indoor environment is associated with the Sick Building Syndrome (SBS).

In the conditions of global urbanization and steady growth of urban population approaches of rational and simple construction are used in modern city architecture. Minimalistic, unnatural urban environment with primitive geometric shapes is created. It forms homogeneous and aggressive visual fields. Visual perception of such landscapes negatively influences on organism of citizens, reduces efficiency and strengthens apathy and irritation. These physiological effects are based on violation of visual perception mech...

One of the parts of sustainable mobility is surely the quality public transport service. It includes the suitable vehicles, as well as the stations, bus stops and various other integrated transfer points of the public transportation system. For the optimization of using these transfer points, as well as overall optimization of public transport services, it is necessary for us to obtain a traffic data in a real time. Nowadays it is not enough to know just the exact position of the vehicle on the map via GPS, with i...

With the beginning of the 21st century, there was a rapid development of technologies allowing to cover elevation of buildings with various plant species, even those that are not adapted to the natural overgrowth of vertical walls. This is the result of changes in the approach to the sustainable design. The technologies that derive from the simplest, proven solutions known for thousands of years become popular. Plants have a number of advantages that are very difficult to replace by modern filtration systems, they...

The library is one of the most important urban institutions with a wide social impact (including its research, educational, cultural and recreational impact).Being in the previous decades, a place, which aimed at building up the manuscript collection, it gradually opened up to the recipient, adapted its character depending on the changing times, today performing the function of a bustling center of culture and pro-ecological thinking.

Prices of urban real estate are formed under the influence of several groups of factors, among which we can identify demand and supply, characteristics of the external market environment, specifics of users, factors of effective use, etc. However, the role of factors is not equal, and the redistribution of their "weight" occurs almost constantly. The importance of the environmental factor (both positive and negative points) is generally not in doubt, but its impact on real estate prices is also constantly changing...

Synergic effect of the individual components of the indoor environment is considered to be a significant determinant of the quality of the indoor environment. The quality of the indoor environment affects not only the user's comfort but also the health of the users of the buildings. The main objective of the paper is to confirm or exclude a statistically significant impact of hygro-thermal conditions on the indoor air quality (IAQ). Hygrothermal conditions and indoor air quality are the essential components of the...

There are many ancient cultures in the world where there are no written sources and material evidence as artefacts preserved. Their identification or even revealing of signs is an important impetus for the initiation of further systematic research. In this sense, Indonesia, including the island of Bali, is a very typical example, where the earliest reliable evidence can be dated not earlier than the 4th century CE. Due to the natural conditions, there are few opportunities for the artefacts of natural origin and e...

Indoor environment is considered to be a basic requirement for human health and well-being. Concentrations of indoor air pollutants are typically 2-5 times higher, and occasionally 100 times higher than outdoors. The condition and performance of the ventilation have a significant impact on indoor air quality. People are ordinarily exposed to high concentrations of pollutants in indoor environments. The consequences of low ventilation rates include elevated levels of carbon dioxide and other air contaminants indoor...

The article considers the prospects of office greening as the smallest unit of housing and communal services, amenable to direct man...

The subject undertaken in the article is poorly researched so far, and at the same time very current, because it concerns the space management strategy in large European cities in the aspect of sustainable spatial development policy. It concerns certain type of Space Left Over After Planning ? areas under elevated infrastructure (bridges, viaducts and flyovers). Underspaces either mostly remain undeveloped for long time or are intended for parking lots or technical facilities. Lack of inadequate management and neg...

This paper presents several issues regarding the dynamic behaviour of the pedestrian footbridges structure under the action of general loads generated by the pedestrians? displacement, together with the correlated traffic comfort of the pedestrians crossing the structure. The footbridge crossing comfort criterion requires the inclusion of vibration frequencies and accelerations of the structures in certain limits so that the vibration amplification or resonance is avoided. The paper puts under investigation six fo...

Many cities in Slovakia are built alongside rivers and the socioeconomic use of rivers is reflected in their urban fabric. Rivers, as sources of water, energy and as sewage effluents, have been used for production purposes and have been surrounded by industrial areas, which today often lose their functions. Brownfields, abandoned and derelict, unused and underused sites along the watercourses, become today areas of urban revitalization and redevelopment. We have explored the spatial, architectural and urban planni...

Cultural buildings constitute a measure of attractiveness and potential in terms of tourism, as well as concerning being places of residence in European cities. When discussing the material value of cultural buildings we can assume that modern buildings, similarly to the greatest historical monuments of cities, can charm and delight visitors, in addition to constituting a driving force behind the economy. The perfect research criterion concerning the role of cultural buildings in the city, however, are the intangi...

Graphic signs and fragments of images on the walls of megalithic buildings and individual stone blocks are not so common. However, their presence greatly enhances the value of ancient monuments of material culture in order to understand the way of thinking of ancient people much better. Portugal is a land where the density of megalithic monuments identified is one of the largest in Europe, but in Portugal itself, in the environs of Evora and Elva the number of such monuments is one of the largest. One of the most ...

The goal of this paper is to define an answer to the question how to design public green areas around multi-family residential buildings and what is their role in the spatial structure of the city. Big cities struggle with the problem of an insufficient share of green areas. Actions are being undertaken in order to introduce green areas in spaces with a high floor area ratio. A good example in this respect is Cracow, where in recent years a project of organising a number of pocket parks has been implemented. Simul...

Architectural styles had a cyclic pattern throughout the history of humanity, however their recurrence was intentional, educated, having more to do with the taste of a society or a group of individuals than with their basic needs. Vernacular architecture emerged as a response to the needs of people and was a collective product, not the masterpiece of an architect. It emerged from the local building techniques and construction material availability, as well as climatic, economic and socio-politic conditions. Underg...

There is a growing need for enhancing resilience of urban systems in the face of unprecedented urbanization and climate change for they both will likely worsen the already unstable and vulnerable nature of contemporary cities: once barely a risk, environmental factors have now the potential to become disasters. Urban resilience means that components of the urban system пїЅ be they natural, built or third environment, human capital, socio-economic activities, etc. пїЅ are able to withstand negative impacts without ...
