The article deals with issues from the initial phase of the investment process connected with revitalizing postindustrial buildings: planning and programming investments in the functional and financial scope, as well as designing. The described formal and legal aspects are the result of a study of a few projects concerning the adaptation of buildings to serving a new function in Zielona Góra and Żaganie. The conclusions drawn from an individual view into each of the described problems are no different than when designing new buildings. It is not until we look into the whole preparation and design process, and gathering all experiences from the formal-legal sphere, that allows us to notice that, in the case of revitalizing postindustrial buildings and their adaptation to serve modern-day functions, a multifaceted but also specific approach is required.
The planning stage of the investment–construction process is of a crucial importance. Its overall impact on the costs, construction time and the quality of design solutions is huge. However, in practice, little attention is given to this pre-design stage, except for public buildings or other buildings of particular importance. In consequence, the results of investment and construction activities are unsatisfactory. Therefore, the issue has been given careful consideration in this paper.
The paper discusses the issue of programming urban revitalization, emphasizing its socio-economic importance. To illustrate the complexity of revitalization projects planning, the author draws attention to social, economic, technical and organisational factors, such as public participation, reorganization and revaluation of land use planning, rationalization of energy use, organization and management of revitalization processes, as well as technical progress. Summarising the paper, the author concludes that in order to improve the quality of life of town residents and to protect material national heritage, it is indispensable to continuously revitalize subsequent town areas.

The studies included 2 water bodies in Cracow (Kraków), 6 water bodies in the commune of Zabierzów (Cracow County) and 4 in the commune of Niepołomice (Wieliczka County). The studies were carried out in June 2018 and May 2019. The ways on management of the water bodies were compared. Problems related to revitalization were identified. One of these problems is the preservation of biodiversity. In some cases revitalization reduces biodiversity. This can happen due to the liquidation or limitation of the reed bed zone. Such a situation was observed in the water bodied of Zelków and Karniowice (com. Zabierzów). Both have ornamental functions now. Removal of most of reed does not disturb mallards (Anas platyrhynchos), but makes it impossible to nest for other birds such as moorhen (Galinula chloropus). Moorhens were observed in two former fish ponds in Staniątki (com. Niepołomice) and in the pond of the Kaczeńcowa street. In one of them revitalization caused the diminishing of the water area, but did not change the character of the water body. Bird species were recorded at water bodies.
Modernization of urban space with greenery is part of a process of revitalization and restoration of building, which today are an important part of the design and realizations activities in the world. Adaptation of urban space to modern needs, often associated with the change of the original function is necessary to improve the quality of this space: utility, technical and aesthetic. Urbanization of the world combined with the destruction of the environment. It is necessary to return to nature in the context of the urban environment. Greater use of green, eco ideas of architecture and sustainable development becomes the norm. The paper presents some aspects of selected projects and activities in the countryside as a method of upgrading urban space.
The subject of this paper covers two issues, namely the issue of brownfields and their conversion and the issue of Facility Management, which offers the possibility of applying its principles and tools for extending the benefit of the construction works as a tool for active access to care for the property. This paper aims to link these two topics and to identify the possibility of applying Facility Management in the conversation process of revitalization of brownfields so that subsequent commissioning eliminates the risk of future costly operation and relapse of the revitalized building into the category of brownfields.
Post-industrial architecture was until recently regarded as devoid of value and importance due to obsolescence, but this awareness has been a clear change in recent years. The old factories become full-fledged cultural heritage, as evidenced by the inclusion of buildings and complexes of this type in the register of monuments and protected by their conservator. More and more often, therefore, one undertakes revitalization of degraded brownfield sites, and within these treatments - conversion works. Specific issues and problems related to the adaptation of industrial facilities are discussed in the article on the basis of selected examples, completed in recent years in Bydgoszcz.

The effect of the conditions of a landscape on its retention capacity
Questions related to the occurrence, frequency, intensity, duration, characteristics and causes of floods have been discussed more in recent years. Two basic approaches to flood control often conflict. The first is based on the assumption of the considerable effect of a landscape's retention capacity, which can in fact prevent surface runoff generation and flood formation and can significantly transform flood wave. The second approach asserts that the retention capacity of a landscape is nearly negligible and that the only reliable flood protection can be provided by extending the technical structures of flood control measures mainly and directly on water courses. Two different approaches were applied to assess the effect of landscape conditions and revitalization measures on surface runoff and flood formation within a catchment and floodplain. The conclusion shows that the effect of landscape revitalization is very important, but mainly for low return periods of flood events, while for extreme events, the effect on landscapes and floodplains becomes less important and even negligible.

Possibility of utilization directing structures in river revitalization
Directing and concentrating structures are mainly used on water courses with unstable channels and major sediment transport or in areas with major bank erosion. The main purpose of these structures is to redirect water flow from the stressed and very often eroded bank to the centre of the channel or other parts of the channel, where the water flow may be used, e.g., for dispersion of unsuitable deposits before its eventual stabilization by natural succession. Another important goal is to achieve a desired change in a stream channel by using the transporting power of the water flow and targeted deposition of any sediment. The area of a deflecting structure, a so-called hydraulic shadow, also appears where sediment is deposited (deflector). The objective is to achieve the deposition of sediments at desired places in the stream. It is possible to design a whole range of suitable or less suitable types of flow deflectors. In our article, we will particularly focus on problems of revitalizing a water course; i.e., the design of structures from biological or biotechnical elements for channel stabilization.
The paper presents the situation regarding the reclamation of post-mining land in the case of particular lignite mines in Poland until 2012 against the background of the whole opencast mining. It discusses the process of land purchase for mining operations and its sales after reclamation. It presents the achievements of mines in the reclamation and regeneration of post-mining land as a result of which-after development processes carried out according to European standards-it now serves the inhabitants as a recreational area that increases the attractiveness of the regions.
Demographic problems, obsolescence of existing buildings, unstable economy, as well as misunderstanding of the mechanism that turn city quarters into areas in need for intervention result in the implementation of improvement measures that prove inadequate. The paper puts forward an algorithm of revitalization program for housing developments and presents its implementation. It also showed the effects of periodically run (10 years) three-way diagnostic tests in correlation with the concept of settlement management.
