 Selection of plants for extensive green roofs in climate zone A: A review Countries in Climate Zone A have much to gain from implementing green roofs as a climate change adaptation measure. Due to the limited research on green roofs in Climate Zone A, the components of a green roof suitable to these geographical locations have not yet been identified. One of the major barriers to increasing the prevalence of green roofs in these regions is the lack of proven plant species suited to green roofs in the tropics. The main objective of this study was to develop a plant screening tool that can identify the plant species that can survive and be aesthetically pleasing in an extensive green roof in Climate Zone A. The methodology of this study consisted of a review of the existing knowledge on factors that influence the selection of plants for extensive green roofs. These factors were then critically analyzed for their relevance to Climate Zone A. The result of this analysis was a plant selection matrix that can identify the plant species putatively suited for extensive green roofs in the tropics. This developed plant selection matrix can provide the green infrastructure industry in Climate Zone A with a greater knowledge for plant selection. 10.57728/ALF.23.1 69 Extensive Green roofs Climate Zone A Plant Selection Vegetation Layer Plant Selection Matrix https://alfabuild.spbstu.ru/article/2022.23.1/

 Factors affecting the quality of construction of unique buildings in Nigeria The object of research is construction of unique buildings in Nigeria. The population is growing, but there is no more land for construction. This circumstance necessitates the construction of high-rise buildings, rather than traditional buildings. The construction industry in Nigeria is quite a chaotic environment through all the stages involved. Developing countries encounter difficulties in the management of construction projects and processes. Method. Experts responded to questionnaires ranking the factors from least important to most important on a 5-point scale. The experts had to have completed at least university education (Bachelor’s). Kendall’s coefficient of concordance (W) was used to measure the agreement between the expert opinions. Pearson’s chi-squared test was used to test the significance of Kendall’s W by determining the existence of a relationship between the opinions. Results. The results of the research showed a significant amount of agreement in the ranking of the experts, especially in the most important factors. Factors directly connected to materials were observed to affect construction projects in the Nigerian environment the most. Labour and type of contract also have significant impact of the success of projects in Nigeria. 10.57728/ALF.23.2 69 High-Rise Construction Factors Experts Expert Opinion A Priori Ranking https://alfabuild.spbstu.ru/article/2022.23.2/

 Mesh building of a toroidal shape with various grid schemes The object of research is a spatial system of a regular toroidal structure with different cell shapes. The purpose of this work is to analyze mesh domes with different design schemes. The considered load, evenly distributed on all elements of the spatial structure. Method. Finite element method in the LIRA-SAPR software package used to determine the qualitative and quantitative indicators of the bearing capacity of the spatial coverage. Results. The analysis of technical and economic indicators for various options for the shape of a building cell and various materials was carried out, as a result of which it was established that the structure using trapezoidal cells is the most optimal; the smallest material consumption is the design using trapezoidal cells; when comparing the material consumption, the most economical option was made of wood, the weight of the wood structure is 81% of the weight of the metal structure. 10.57728/ALF.23.3 69 Structure Mesh dome Metal constructions Wooden structure Grid Spatial system https://alfabuild.spbstu.ru/article/2022.23.3/

 Structural and technological features of modular multi-storey buildings. A review Volumetric-block construction has many advantages compared to traditional construction. Still, its development is hampered by the lack of experience and information on the construction and design of modular buildings, and the lack of construction regulations with their clear classification. This work aimed to accumulate and systematize experience in the field of volume-block construction to create an unambiguous classification of modular buildings. The research was conducted using the general scientific method of analysis, synthesis and classification of information. The review systematized data on existing classifications and terms in the field of modular construction. The classifications by functional purpose, by materials used, by design features, as well as types of modular connections are considered. The experience of volume-block construction is also widely studied. 10.57728/ALF.23.4 69 Building construction Building design Module Modular building Prefabricated modular Modular facade Classification https://alfabuild.spbstu.ru/article/2022.23.4/ 2304.pdf

 Software for carbon dioxide emissions in construction. A review The object of research. A comparative analysis of software that allows the carbon footprint of a projected building to be determined at an early stage in terms of functionality has been carried out. A description of the software and services under consideration and their advantages are given. Carbon emissions for the building envelope of the building under renovation are assessed. A recommendation is made for a rational combination of building envelope layers with minimal impact on the environment. Results. It was revealed that the emission readings of the same material may differ by a factor of 2 to 3 depending on the composition, additives, manufacturer and combination of the structure. The use of energy-efficiency materials is one of the keys to a sustainable system. 10.57728/ALF.23.5 69 Carbon dioxide emissions Energy efficiency of design solutions Energy-efficiency Building materials Renovation https://alfabuild.spbstu.ru/article/2022.23.5/ 2305_1.pdf
