Abstract Not long ago, the sustainability of buildings was not taken as a design priority, although it was considered to some extent. The required level of sustainability has risen sharply in recent years, buildings are becoming more self-sufficient, environmental friendly and greener. Towards more attention to green sustainable alternatives in architecture, new solutions for sustainability began to be sought, such as the use of vertical and horizontal surfaces of the building for green facades, the use of roofs for roof greenery, as well as introduction of greenery into building in the form of green walls. Along with the introduction of greenery into the interior comes the new necessary technical solutions, thinking about the overall green wall with respect to the indoor environment and building itself as well as new possibilities of using rainwater, beautify the interior, improving the air etc. However, it is important to perceive a green wall as a living element that must be sustainable, and this is what this article is about. The article focuses on the green walls from the point of examining the available information on this subject in domestic as well as in foreign sources. The results of this article can help to improve understanding of various green walls from different perspectives and compare their view on the green wall in terms of sustainability. The paper helps designers and researchers to orientate in the given topic to create an overview of the different options of the current greenery systems.

Ensuring the stability of mining excavations is a crucial aspect of underground mining. For thispurpose, appropriate shapes, dimensions, and support of workings are designed for the given mining andgeological conditions. However, for the proper assessment of the adequacy of the used technical solutions,and the calibration of the models used in the support design, it is necessary to monitor the behavior of theexcavation. It should apply to the rock mass and the support. The paper presents the automatic systemdesigned for underground workings monitoring, and the example of its use in the heading. Electronicdevices that measure the rock mass movements in the roof, the load on the standing support, and on bolts,the stress in the rock mass, are connected to the datalogger and can collect data for a long of time withoutany maintenance, also in hard-to-reach places. This feature enables the system to be widely used, inparticular, in excavations in the vicinity of exploitation, goafs, or in the area of a liquidated exploitationfield.

Nowadays, in a rapidly developing urban environment with bigger and higher public buildings, disasters causing emergency situations and casualties are unavoidable. Preparedness and quick response are crucial issues saving human lives. Available information about an emergency scene, such as a building structure, helps for decision making and organizing rescue operations. Models supporting decision-making should be available in real, or near-real, time. Thus, good quality models that allow implementation of automated methods are highly desirable. This paper presents details of the recently developed method for automated generation of variable density navigable networks in a 3D indoor environment, including a full 3D topological model, which may be used not only for standard navigation but also for finding safe routes and simulating hazard and phenomena associated with disasters such as fire spread and heat transfer.

In recent years, many researchers have addressed the issue of interior climate and how it affects human health. Investigations performed at schools and office buildings have found that CO2 concentrations often exceed the limit value of 1500 ppm given in Decree No. 20/2012 Coll., on technical requirements for buildings. In addition, interior space often exhibits very low relative humidity. This results in poor conditions that are detrimental to human health and not conducive to studying and work. One means of improving the interior microclimate is implementing green walls. These walls can help generate a much better climate and greatly enhance the mental well-being of the inhabitants. In addition, they greatly improve dust levels and acoustics in the room. The research compared the interior conditions in two classrooms at the Faculty of Civil Engineering, Brno University of Technology. One had a green wall installed while the other was in its original configuration. CO2 concentration, temperature, and relative humidity were measured. A survey was conducted to assess the influence of the green wall on students and teachers (mental well-being, efficiency, productivity, creativity, etc.). Results obtained thus far show that the room with the green wall provides far better interior conditions, mainly in terms of lower CO2 concentration and higher relative humidity, improving students’ and teachers’ mood and health (as confirmed by the survey as well).

The article presents briefly, in a personal vision, the execution of a public monumental work, with a religious theme, namely The Wayside Cross, with a step-by-step description of the phases of design and execution of the necessary components resulting from the project. The entire work is realized in a contemporary, personal innovative vision, and the variety of materials and techniques that were used are meant to emphasize the complexity of its building. The paper highlights the difficulties in establishing formal motives for the given theme and describes the moments when the Divine inspiration and protection were felt during the elaboration process, giving a very special note to the evolution and completion of the whole artistic approach. The mosaic - of pictorial type - is different from the slightly monochrome chromatics characteristic for the tradition of this type of monument-size representation. The basic structure of the cross pedestal, with candle shelves; the perfectly symmetrical, metallic, laced grids, of great technical difficulty; the side windows carefully made in the stained-glass technique – the Tiffany technique; the whole range of technical solutions for their installation inside the edifice that shelters the work, as well as the harmonic insertion of the complex into the ambiental atmosphere of the site, all these were challenges of high complexity. The result of this long execution process of about 5 months and its assembling in a unitary religious complex, namely the Wayside Cross, was received with real appreciation both by the priests of the parish in which it is located and by its parishioners, inhabitants of Între Lacuri district from Cluj-Napoca.

This research is a preliminary study of planting ornamental plants with a green wall system. This study aims to provide an overview and information about the selection of types of plants that are suitable and commonly used in making green walls and arranging selected plants in green walls system. Green wall system which is often called vertical garden is a technique to plant ornamental plants, vegetables or other types of plants with a free design that considers various resources that allow plants to grow vertically. The advantages of green walls are efficient use of soil, beautifying the environment, adding location value, cleaning the air, lowering temperature, producing oxygen and providing fresh food that is close to the surrounding environment at home. Not all types of plants can be planted vertically. Easy-to-grow plants, short appearance and slow growth are common characteristics used for green walls. The special characters of the selected plants are determined based on the group of indoor or outdoor plants. Consideration of nutritional, light, water and plant requirements will determine the success of planting and the sustainability of vertical planting.

To mitigate the urban heat island (UHI) and release the low carbon potential of green walls, we analyzed the cooling and energy-saving performance of different green wall designs. Envi-met was applied as the main simulation tool, and a pedestrian street named Yuhou Street was selected as the study object. Four designs of walls were summarized and simulated, demonstrating the living wall system (LWS). Super soil had superiority in cooling and energy saving. Outdoor air temperature, indoor air temperature, outside wall surface temperature, and inside wall surface temperature were analyzed. Apart from the outdoor air temperature, the other three temperatures were all significantly affected by the design of green walls. Finally, energy savings in building cavities were determined. The indoor energy saving ratio of the LWS based on super soil reached 19.92%, followed by the LWS based on boxes at 15.37%, and green facades wall at 6.29%. The indoor cooling powers on this typical day showed that the cooling power of the LWS based on super soil was 8267.32 W, followed by the LWS based on boxes at 6381.57 W, and green facades wall at 2610.08 W. The results revealed the difference in cooling and energy-saving performance of different green walls in this typical hot summer area.

Green walls are bio-filters developed to enhance air quality. Often, these walls form the base from which plants are grown; and the plant-wall system helps to remove both gaseous and particulate air pollutants. Green walls can be found indoors or outdoors and they are classified as passive or active systems. Their benefits include temperature reduction, improvement of air quality and reduction of air pollution, oxygen production as well as the social and psychological wellbeing. They can produce changes in the ambient conditions (temperature and humidity) of the air layers around them which create an interesting insulation effect. The effect of passive green wall modules on the air temperature and on humidity is investigated in this work. A closed chamber made of acrylic sheets is used to monitor the temperature and humidity variation caused by a green wall module placed at its center. Temperature and humidity are measured at different locations inside the chamber during operation for different modules with different plant species.
