The green building certification system has long-lasting benefits by improving building efficiency and sustainability. The ultimate goal of such classification is to promote the preservation of the global environment as well as the occupants’ well-being and their health. In this paper, we present examples of buildings that have been designed and built in Poland and have been certified with BREEAM, LEED and WELL. Our study investigates human factors in certification systems and examines the WELL Building Standard as a supplement to other green systems, which will probably be the most popular in the future. The green building movement should prioritize pro-human factors and the associated environmental beliefs to improve indoor environment quality for users’ needs. We present this matter on the example of the Polish office space market, providing statistics and analyzing the architecture of six certified office buildings from Warsaw, Poznań and Wrocław. They are a representative sample of buildings designed following the certification regime. It was demonstrated how this aids in improving work comfort, enhances the program of office spaces and the organization of service spaces within buildings, which increases the rank of this architecture and positively affects the urban environment.

There are more than a hundred historic public buildings in the centre of Wrocław, adapted to fulfill modern commercial function. Against the background of today’s cosmopolitan shopping centers and office buildings, these buildings are distinguished by stylish architecture, maintained in eclectic, Art Nouveau or modernist forms. In the process of renewal of such monumental buildings, there is a need to reconcile the requirement for maximum protection of the historic material with safety and comfort of use. The multi-disciplinary construction design constituting the basis for the adaptive reuse of the heritage building must be preceded by conservation research and concept designs simulating possible program options. This allows linking the assessment of the value of the architecture with a choice of the matching function corresponding to the location and historic structure of the building. The further multi-disciplinary design process and implementation of such a project should be based on the Research by Design scheme. This allows for control of the implementation of the project and to rationalize the necessary upgrade of the facility with the application of such space and technical solutions that limit the destruction of its historic substance. The paper presents conclusions from several adaptive reuse projects carried out in such a way, in which it was possible to create high-class department stores, banks, hotels or prestigious offices inside the heritage buildings. The essence of these developments was to preserve the authenticity of the monumental building, while providing the necessary infrastructure, plant rooms and equipment guaranteeing safety and comfort of use.

This paper presents the role and potential of housing built using innovative reinforced concrete prefabrication technologies. The subject was presented by investigating the share of such buildings in the achievement of housing goals in Germany and Poland, where they currently constitute one of the most dynamically developing housing sector branches. The phenomenon has been presented via comparative analyses of selected designs by manufacturers from the sector and development companies. Prefabrication is essentially based on optimising architectural and structural solutions and leads to lowering financial and material cost; decreasing project completion time. At present, these goals are achieved by systematising the design and construction process and using the potential offered by building information modelling technology (BIM). This enables coordination between design specialisations and reduces the number of errors, increasing manufacturing and assembly efficiency. Innovative prefabricated technologies are solutions that are either new or are considerably improved in terms of technical specifications, components and materials, that use the latest software, are easy to assemble, durable, energy efficient, can be disassembled and reused and have a low carbon footprint and can be considered aesthetically pleasing. Contemporary prefabricated housing architecture is a combination of innovative technological solutions that enables constructing sustainable architecture and emphasizes the aesthetic features of structural solutions and solutions.
