Adapting historic buildings to new, modern forms generates not only financial benefits for developers but can also allow them to survive for future generations through proper remodelling. The variety of decision criteria related to the selection of a new function of a historic building makes this problem multidimensional. Many of these criteria are interrelated and have a non-linear nature which requires a comprehensive network-based rather than a classic hierarchical approach to conducting multi-criteria analysis. A comprehensive approach taking into account the specificity of the analysed problem was proposed. The study was supported by an example of the choice of building function as part of the adaptive reuse of a historic building located in Zakopane. The following variants have been analysed: a hostel (existing state), a five-star hotel, a folk art gallery and a conference and training centre. The final rating of alternatives indicates that the hotel best meets the adopted decision criteria.

Kinematic loads resulting from earthquakes or human induced events can act on engineering structures. Poland is not an active seismic region. In south part of Poland there are located quarries and mines. Surface and underground exploitation of mineral resources results in regional seismic phenomena. Seismic waves originating from these phenomena are travelling towards surface and in form of surface wave can impact the structures. Mining-related surface vibrations show a lot of similarities with earthquakes but also some differences. In previous years the main load used in design procedure of buildings in mining regions in Poland were dead and live load, technology load and gusts of wind. The structures were not designed to dynamic loads resulting from mining-related vibrations of ground. Dynamic loads acting on buildings result in extra inertia forces which load those structures. This specially concerns to residential masonry objects which present group of structures frequently occurring in mining areas. In many cases, these buildings are characterized by irregularities in their construction, and this significantly reduces their dynamic resistance. The paper presents the selected problems of analyzing selected masonry building with irregularities in structure using finite element method (FEM). The analysis relates to dynamic effects caused by surface vibrations. The selected problems with assuming the kinematic excitations and soil-structure interaction are presented as well as some aspects of constitutive modelling of masonry structures. The paper also includes comparison of earthquakes and mining-related tremors. The differences in frequency domain and significant duration of intensive phase are also discussed.

The article presents the results of vibration measurements from passenger train journeys from the ground to the building foundation. The vibration acceleration courses from the Pendolino passenger train were used for the analysis. The measurements were carried out in a single-family brick building at the existing railway line. The measurement results can be used in the future to analyze buildings located at railway lines where passenger traffic takes place. The results of the analyzes can also be useful in assessing the impact of vibrations from the railway line on people staying in buildings.

The aim of this article is to check comfort in the passive buildings located in Libertow (close to Cracow). The two aspects of comfort are described: a thermal comfort with tightness and humidity and a vibrational comfort. The main results of measurements of the comfort aspects are described and shown. Passive buildings which were investigated are very tight and well insulated. It is good for the energy saving and for the budget of the owners but it could be a problem for the humidity requirements. In such buildings, there also could be a problem with solar energy excess which could provide that the rooms are overheated. The vibrational aspect is also often neglected on the design stage, but it also could be a problem when the residents live in their homes. The problem is that when a house is built, the costs of changes to adapt the rooms to the appropriate comfort level are much higher than in the design stage. The alternative may be a properly designed floor which shall meet all thermal and vibrational aspects of comfort. In order to improve the quality of multi-faceted comfort, three types of flooring have been proposed. All three are clearly described and their advantages and disadvantages are shown. The main goal of this article is a detailed cost analysis of these three types of floor. Cost analysis was made according to the Polish requirements so-called Catalogs of Material Inputs in the NormaPRO. Costs were estimated using detailed, simplified and mixed methods. The most effective and economically justified type of floor was also chosen.

Transport vibrations are the subject of many research, mostly their influence on structural elements of the building is investigated. However, nowadays, especially in the centres of large cities were apartments, residential buildings are much closer to the transport vibration sources, an increasing attention is given to providing vibrational comfort to humans in buildings. People who buy apartments in the tourist attractively cities like Cracow expect to be very close to the downtown and at the same time to have quiet place to rest without any annoyance coming from transport vibration. Unfortunately, tourist attractively cities are mostly old cities with old buildings which were not designed for dynamic influences which are now in the neighbourhood. At the same time, old buildings are under the conservator care, who limits the possibility of using some solutions. There are three types of possible protection against vibrations: vibroinsulation in the source of vibration, vibroinsulation on the way of propagation and solutions in the building. The first solution depends on goodwill of infrastructure owner, the second could be complicated in the city centres and the third is the best for apartment owners but it could be expensive. The paper presents three different types of vibro-acoustic floor with different layers' configuration. Their advantages and disadvantages are also shown. In the article the main emphasis was put on the technology of making these three types of floors in terms of the possibility of their assembly in a historic building. Detailed technological parameters have been described. The paper also proposes vibroacoustic materials that can be used as a floor layer which could isolate from transport vibrations

The article contains good practise recommendations related to the proper performance of measurements of comfort in passive buildings. Passive building is a high-quality building due to impeccable construction in terms of building physics. The passive building is so well insulated that it can only be heated by supplying fresh ventilation air. Such buildings have certain features such as: balanced temperatures, there is no overheating of the rooms in summer due to the high insulation of the partitions, high insolation due to the optimal positioning of the windows, acoustic comfort, reducing pollution in the interior, high quality of thermal comfort, no aeration, high indoor air quality, permanent protection against moisture and fungiculation of partitions, etc. In all the features listed above, there was no vibration comfort, which could be a problem especially in the city centers with extensive transport infrastructure. This kind of comfort is mostly neglected during the design process, not only in the passive buildings. In this article comfort in passive buildings for all its aspects is described. The main emphasis in the article was put on the guidelines relating to the measurement of thermal comfort and measurements of vibration comfort. The recommendations contain all stages of the measurement process from the preparation of measurements with the local vision and the measurement plan, through the in-situ measurement to pre-processing and analysis of measurement data. All measurement stages are shown on the real example of passive building located in Poland. The good practise guidelines for comfort measurements could be very useful in the diagnosis of passive buildings and NZEB buildings.

Energy efficiency is a very important factor in the Building sector. Building sector consumes about 40% of the world total energy. At present, new buildings in Poland and other European countries are designed according to very strict requirements. The problem arises when we take into consideration large number of the existing buildings. These buildings, especially the ones built in the last century, consume a lot of heating energy. Thermal protection requirements for the existing buildings subjected to thermo-modernization are specified in the technical regulations. Thermal protection requirements for thermo-modernized buildings in different countries are different. In Poland, a thermos-modernized building must meet the requirements for thermal protection of external partitions. In Ukraine, the requirements of thermal protection are modelled on European regulations. In Ukraine's, thermos-modernized buildings must meet the requirements for thermal protection of external partitions and primary energy requirements. However, in Poland thermo-modernized buildings do not have to meet the requirement for a non-renewable primary energy factor – EP. [kWh/(m2y]. The existing buildings do not always have the option of converting a non-renewable heat source into renewable heat sources. In the article, the authors presented the energy analysis of adapting an existing building to the current technical requirements in Poland (WT 2017) and to the level of requirements for buildings of "almost zero energy consumption NZEB" (WT 2021) and adapting an existing building to the current technical requirements in Ukraine. The analysis was carried out based on thermo-modernization audits carried out for a single-family residential building. The analysed building was built in 80's in traditional technology. It is a two-story building located in Krakow. The audits considered various options for improving energy efficiency. Financial outlays for each variant will be determined. The authors of the article pointed out that comfort in buildings subjected to thermo-modernization a very important issue. On the example of an existing residential building, the authors analysed how to improve the vibration comfort of use in the rooms of a building.

The aim of this article is to check vibrational comfort in near zero energy building (NZEB) which is often neglected for this type of building but could be annoying for residents. Building chosen for analysis is experimental building of Malopolska Laboratory of Energy Efficient Building which fulfils requirements for NZEB. The main advantage of this building is that it was design specially for research purposes and it has fourteen zones independently controlled. These zones give opportunity to ensure thermal, humidity, luminosity comfort, but do not measure vibrational comfort. Building is located in the city center of Krakow and very close to Szlak street on which cars and vans move. In this article the vibrational measurements carried out on the top floor of the building are presented. Results indicate that vibrational comfort should be taken into account in NZEB. Second part of the article describes possibility to ensure vibrational comfort in such a building by floor specially design for these purposes. In the city centres, vibro-acoustic floors could be the only solution when vibrational comfort during day or night is exceeded. Three different types of vibro-acoustic floor with different layers' configuration are described. Their advantages and disadvantages are also shown. In the end, cost analysis is made for different types of floor solutions and the most optimal solution is chosen. The selection is made not only by economic reasons but, above all, by functional premises. The floor solution chosen to be used in Malopolska Laboratory of Energy Efficient Building first of all should ensure the vibrational comfort during daytime because it is office building not residing in the night. The owners of the building will be offered an economic option that meets the requirements of vibrational comfort during the day and an exclusive option that will ensure that the vibration threshold of perception will be not exceeded.

The idea of Sustainable Development means caring for the environment and the natural resources. Building and transport are the sectors with the highest energy consumption. Building is responsible for about 40% of total energy consumption. Thermal protection regulations for buildings are becoming more and more severe. The 2010/31 / EU Directive on the energy performance of the buildings imposes on the member states of the European Union the necessity to introduce a standard of buildings of almost a zero demand for energy (NZEB). The requirements for these buildings (NZEB) are determined for each member country of the European Union. In Poland, the requirements for buildings (NZEB) are included in the Technical Conditions. In the article, the authors present energy and cost analysis of adapting a building that meets current requirements to the requirements adopted for NZEB in Poland. The requirements for new buildings are formulated for the building envelopes and for the factor determining Primary Energy (PE). To improve thermal protection of the envelopes, for example, the insulation thickness should be increased, or windows of better coefficients should be used. To improve the PE coefficient, the amount of energy coming from Renewable Energy Sources should be increased. The improvement of thermal efficiency is associated with additional costs. The aim of the article is also to show that reducing the amount of energy necessary for heating a building is not enough to design a comfortable home. The authors pointed to the need of ensuring multi-criteria comfort in NZEB. Buildings of low energy demand are very tight and well insulated. Often, in such buildings a problem with solar energy excess appears and, consequently, the rooms are overheated. On the example of a residential building, the Authors show what costs should be covered to adapt the building to a standard that meets the requirements of the NZEB and a building comfortable for users. The analysis was carried out to improve thermal and vibrational comfort. This paper presents a fragment of research and development works carried out in under the project "Development of innovative modular construction technology, prefabricated on a wood base by Palettenwerk Kozik Sp.j." This is a new technology, developed in cooperation of PalettenWerk Kozik and Cracow University of Technology, with the support of the National Centre for Research and Development, which will have properties that significantly exceed the technology currently available on the market. Buildings made according to the developed technology with using laminated wood crosswise will be characterized by high thermal and acoustic insulation as well as high energy efficiency.

In this article, the authors propose ways to evaluate the criteria for the considered variants of utility functions in the adaptation of historic regional architecture. The proposed set of assessment criteria (thermo-modernisation criteria, comfort of use, financial considerations, criteria of social benefits, and protection of cultural heritage) emphasises the multidimensional character of the problem of choosing a new function for a historic building. Some of the criteria are measurable while others are difficult to measure, which requires an expert approach to their assessment. The evaluation of the criteria was performed on the example of the historic building ‘Stara Polana’ located in Zakopane. The benchmark for the analysis was the existing condition of the ‘Stara Polana’ building, which is used as a hostel. The authors conducted a series of interdisciplinary studies specifying the potential of the new utility functions considered for the object in the context of the proposed criteria. The evaluation of individual criteria developed in this article is based on the multi-criteria analysis to be performed in the future and support the selection of a new function for the building in question.

In the twenty-first century, the seismic design of buildings seems to have become a fully recognised topic. There are guidelines and standards which should be taken into account by designers in seismic areas. Designers using modern international guidelines have ascertained that the behaviour of structures is not as expected. This may be the result of not taking into account the duration of the shock. The duration of surface vibrations could be one of the basic reasons why some buildings collapse or suffer severe damage to bearing systems as a result of long-duration earthquakes despite being properly designed in accordance with current understanding. Another primary reason for such collapse or damage is that some buildings in seismic areas have irregular structural systems that are sensitive to torsional vibrations. In this paper, a five-storey, irregular-shaped RC building model was subjected to different types of excitations: mining tremors, short-duration earthquakes, long-duration earthquakes. The first stage was a modal analysis based on in situ measurement. After model verification using in situ measurements, the building was then subjected to the three forms of excitation. Numerical studies were performed using a verified FEA model of the building in the time domain. The results of the calculations prove that the duration of the intensive phase of extortion is one of the reasons for the lack of building collapse in mining areas. In cases of mining shocks with a short duration of surface vibration, damage to buildings may occur which does not threaten the safety of their construction. Building collapses occur with earthquakes which are characterised by a much longer duration of the intensive phase of excitation compared to mining shocks. The results of in situ observations of RC structures that have survived a history of mining shocks of varied intensities confirm the results of numerical analyses.

Placing emphasis exclusively on minimizing energy consumption in low-energy buildings can adversely impact thermal comfort and vibrational comfort. Vibrational comfort is extremely important in building design, especially within mining or seismically active territories, and due to car transportation in city centers. In this article, a new approach to designing passive buildings and nearly zero-energy buildings (NZEBs) in Poland is proposed, which has a strong emphasis on the necessity of providing comfort of use in passive houses and NZEBs. Additionally, vibration comfort provisions in the design process are examined. The research gap that will be addressed by the research presented in this article is to extend the comfort conditions of passive buildings and NZEBs into the area of vibratory comfort. The second goal of the project is to determine the impact of solar control systems on the conditions of thermal comfort. The conclusions from the research will allow for the optimization of design assumptions for passive houses and NZEBs. The conclusions from the tests can serve as the basis for introducing appropriate construction law requirements in Poland. The results of the research, which are presented in the article, indicate that the technical requirements that are applicable in Poland ought to include requirements regarding the use of sun blinds in NZEBs and passive buildings (not only as recommendations). In particular, the use of apertures on the south side ought to be mandated. The article can also be the basis for introducing the requirements of vibration comfort to the PN–EN 15251:2012 “Indoor environmental input parameters for design and assessment of energy performance of buildings addressing indoor air quality, thermal environment, lighting and acoustics” standard, which is the basis for designing the parameters of the internal environment for buildings.

This paper presents a selection of vibration measurement results and analyses performed with regard to their harmfulness to residential buildings. The first part of the paper refers to the analysis of railway vibrations measured in situ at the foundation level of residential building. These vibration records were then used to assess the harmfulness of vibrations relating to each train speed. Assessment of the vibration harmfulness of the building was performed with an indicator of the perceptibility of vibration through a structure (WODB), according to the Polish standard. The second part of the study refers to the creation of dynamic models of buildings with the use of the ‘Diana’ software program and analysis of their responses to railway vibrations. The thresholds specified by the standard in any of the train speeds of up to 250 km/h were not exceeded. Nevertheless, propagation of vibrations induced by train passages and their effect on the structural response of buildings is a complex phenomenon. Without in situ measurements, it is hard to assess the impact of induced vibrations on buildings. As proven in the paper, a train moving on a track at various speeds does not uniformly make the vibration greater in each frequency band.

Human perception of vibration could be the basic parameter in designing a new buildings located close to public transport. It is also one of parameter that is considered in diagnosis of building vibration. People perceived vibrations through the floor. The problem of floor vibration appear especially in old historical buildings with wooden floor when source of transport vibration change because of infrastructure development. During years road, tramway or railway infrastructure is more expanded that it was when the old buildings were built. That is why new solutions of protection against noise and vibration are needed. One of that kind solution could be vibro-acoustic floor which can reduce impact sounds and vibrations. A flooring system that insulates both acoustically and vibrantly is a common solution to reduce noise coming from impact sounds or to propagate from lower levels to higher ones and to limit the influence of vibration on people receiving vibration in buildings passively. The flooring system should therefore be capable to damp vibrations up to 100 Hz and have sound insulation of min. 25 dB. The composition of vibration insulation materials and their material parameters will be selected to optimize the acoustic and vibration protection. At the same time, the acoustic and vibration-insulating flooring system should have all the functional features that are common to the floor: ease of installation and adequate rigidity. In paper three types of vibro-acoustic floors will be considered: with full vibro-insulation, with insulation strips and with point insulation. Advantages and disadvantages of these three considered solutions will be presented. The paper is pilot study to in-situ measurement which will be held under the project of EU commission support.

The work concerns the monitoring of the technical condition of metro trains. For this purpose, a vibration monitoring system installed in buildings in the vicinity of the underground is used. Based on measured vibrations buildings, the identification of technical condition in metro trains is conducted. The results of measurements from the system are also used to assess the impact of vibrations on people staying in buildings through the WODL ratio. Exceeding the assumed levels of the WODL ratio is the basis for repairing trains by turning wheels. Statistical analysis of the data was implemented and trends for particular time periods of measurements were shown. With the entered monitoring system and the introduced WODL index thresholds, it is possible to better plan the costs associated with the repair and replacement of wheels of rolling stock, where there are large values of radial runout. According to the introduced monitoring procedure, the number of complaints from residents decreased and the comfort of their lives improved.
