The paper ­describes the verification of the quality of the data transfer between selected software dedicated to generation of building models and for their analysis using the finite element method. For comparison, models of two typical structures are constructed: a steel truss hall and a multi-storey reinforced concrete building. Both models are created simultaneously in two programs: Autodesk Revit and Tekla Structures. Next, these models are exported to computational packages: Autodesk Robot, Dlubal RFEM and SCIA Engineer. Different options of data transfer are considered, in particular: a direct link between programs as well as via open formats. The scope and limitations of the data exchange are determined in each case. Juxtaposition of the effectiveness of different transfer methods for such typical building models are helpful at the stage of cooperation between the architect and the structural designer. In addition, pilot results of a finite element static analysis for the steel hall model are also compared.

Historic arcaded houses are part of the material heritage of the Vistula  Delta. Unfortunately, their number is decreasing year by year. The article is the result of a query of available sources and field research carried out by the author in 2015-2020. The paper presents the current state of preservation the historic arcaded houses in Vistula Delta listed in the National Inventory of Historical Monuments. Criteria for the selection of test objects are described. The author has prepared a tabular list of arcaded houses with information about their location, type according to Kloeppel statistics, date of construction, technical condition and functions. The summary of the analysis are pie charts with a statistical presentation of the data collected by the author during the research.

The article deals with the issue of solar facades as the main external walls of a building, adapted to make use of solar energy. The aim of the article is to define the role of the facades and the factors that influence shaping thereof. The goal is of cognitive nature, whereas its implementation may contribute to strengthening the relationship between presumptions related to energy and architecture in the design of buildings. The need for the article results from the necessity to search for a possible balance between technical and humanistic spheres while shaping contemporary pro-ecological architecture, especially one aimed at receiving solar energy as a renewable energy source.

In the article, both analytical and comparative methods are applied. The research was conducted on the example of four designs with solar facades of different characteristics, including two buildings planned by the author.

The research results are observations that define relationship between the energy-related role of solar facades and urban, functional and aesthetic issues. These observations lead to the conclusion that the energy aspect, is not the only one to be considered while shaping solar facades in contemporary architecture. The solar facade combines both functional and artistic features.

The purpose of this paper is to contribute to development of approaches to the evaluation of the design of public open green spaces (POS). This paper presents a universal standard for the design of health-promoting urban places. The standard is a conceptual framework which was developed after visiting over one hundred public parks and therapeutic gardens in Europe and the United States. The universal standard is a simple and effective tool that can be used by both professional designers and non-professionals to improve the health-promoting qualities of open green spaces. Rahway River Park, designed by Olmsted Brothers in 1925, serves as a case study.

The basis for recognising claims for mining damage to a structure should be a mining and construction analysis, carried out following a detailed visual inspection of the damage and the results of surface deformation measurements. It allows to establish a cause and effect relation between the activity of the mining company and the damage. Unfortunately, there are cases when such an analysis is omitted and the following scheme is used: "since there is damage and the object is located in a mining area, it is mining damage". The problem is illustrated by two court cases where the author acted as an expert witness. Both cases are examples of the so-called pseudo-mining damage and confirm the thesis that the mere image of damage without professional analysis of construction and mining factors may lead to wrong conclusions regarding the causes of the damage.

On 28 June 2015 an amendment of the Polish Building Code that abolished a requirement to get a building permission to construct or reconstruct a free standing one-family house, which impact area is limited to the plot on that it is planned, came into force. Since then an erection of such houses has been possible on a basis of notification instead. The goal of this amendment was to simplify the development process in the case of one-family houses. This article is a contribution to the verification of this assumption. Therefore data on notifications that were submitted to respective capital city of Warsaw districts’ offices  have been analysed. Detailed research has been limited to the districts of Bielany and Białołęka.

The article addresses the problem of the decline in the number of tourist facilities with outstanding features of regional architecture, built before 1945 in Kłodzko Land. Their destruction is an irreparable loss for the cultural heritage of the described region. Usually designed in the spirit of the local building tradition – born out of centuries of experience of the people living here – hostels, inns and taverns were a characteristic, regional distinguishing feature of the landscape of Kłodzko Land. Meanwhile, the new architecture of objects related to tourism, built after the end of the Second World War, most often does not refer to the characteristic forms and structures of local buildings. The article stresses the need to put an end to the often deliberate practice of destroying old pre-war buildings and to draw the attention of architects working today to the importance of continuing local, regional forms in the emerging tourist facilities.

The paper describes the research on the method of production of granulated phase-change materials (PCM) used in construction industry for the accumulation of thermal energy. As mineral materials for the granules preparation zeolite from fly ash Na-P1 and natural diatomite dust were used which were impregnated with paraffinic filtration waste and granulated using a combined granulation method. Obtained granules were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption/desorption isotherm, and differential scanning calorimetry (DSC). Mechanical strength of the materials was determined in a “drop strength” test. Performed analyses revealed that mineral composition and micromorphology of the diatomite and zeolite granules were varied, with zeolite granules having higher mechanical strength.
