Implementation of "Green Building" in construction is the responsibility of all parties involved in the construction project. The Office of the Federal Environment Executive (OFEE) defines green buildings or green buildings as “the practice of increasing the efficiency by which buildings and their sites use energy, air, and materials, and reducing the impact of buildings on health and the environment, through better siting, design work. construction, operation and removal - maintenance of the complete building life cycle. (Kubba, 2017). At the planning and implementation stage of a construction project the selection of building materials or materials must be precise but also efficient. The concept of eco-efficiency was introduced in 1991 by the World Business Council for Sustainable Development - WBCSD and includes “the development of competitively priced products and services that meet the needs of the quality of human life, while progressively reducing impact on the environment and consumption of raw materials throughout the life cycle accordingly. with the capacity that is on planet earth. "This concept means producing more products with less resources and less waste, and therefore this concept has less impact on the environment. Then it is necessary to assess all the environmental impacts caused by the extraction of raw materials from the start of the material being given (cradle) to the end of its service life (tomb). The research objective is to develop environmentally friendly materials for problem solving materials, electricity and plumbing. The results of the analysis show that the mechanical, electrical, and piping materials used in the Maranatha Sport Center project have not met the 7 overall environmentally friendly criteria for the material-life-span stage, however, each material used has the main green criteria that have been self-declared by each. -Each material manufacturer.

Urban population has been increased rapidly and caused such urban problems as shortage of housing and traffic jam, and the continuously expanding buildings have resulted in strong impact on global resource consumption and environmental pollution. Green building materials are the basic guarantee to the quality and service life of buildings, the material carrier to realize various functions of buildings and also the foundation and support to develop green buildings. Based on the coherence and relevance of assessment on full life cycle of buildings and building materials, the influence of exterior window selection on carbon emission of buildings was analyzed in aspects of the initial stage (production, consumption and transport of building materials) of carbon emission of buildings, i.e. the intrinsic energy per unit product, operation, demolition and treatment. The comprehensive assessment was also established, and the selection of green building materials was investigated for exterior windows based on the reduction of energy consumption during full life cycle of buildings by combining such indicators as the usability, durability, fireproofness, environmental protection and functionality of exterior windows. It solved the puzzles of architects on selection of building materials and the puzzles of building material manufacturers on demand of green buildings. The selection of green building materials on green buildings was promoted and the realization of the goal of "green buildings" also assisted.

The green building design aims to minimize the need for the non-renewable energy of these resources, optimize their sustainability and maximize their conservation, recycling and usage. The use of effective building materials and construction techniques is maximized. Architectural bioclimatic technology will also optimize on-site usage of sources and sinks. It requires only minimum electricity to fuel itself and efficient appliances to meet its lighting, air-conditioning and other needs. Green buildings architecture optimizes the use of renewable energies and efficient waste and water management methods to create practical and hygienic working conditions for indoor environments. Materials such as chemical, physical and mechanical material properties and an appropriate specification are the fundamental elements of construction design and responsible for the mechanical strength of the design. The construction of green buildings is also the first step in choosing and utilizing eco-friendly materials with or better characteristics than traditional building materials. Based on the practical, technical and financial requirements, construction materials are usually selected. But, given that sustainable development has been a core issue in recent decades, building industry that is directly or indirectly responsible for a substantial share of annual environmental destruction, by pursuing environmentally sound constructions and buildings should take responsibility for contributing to sustainable growth. The quickest way for manufacturers to start integrating environmental design practices into buildings would be the diligent procurement of eco-friendly sustainable construction materials, including options for new material uses, recycling and reusing, organic product creation and green resource use. This paper aims to show how green building materials will help reduce the impact on the atmosphere and create a cleaner building that can be healthy for the occupant or our environment. In the sustainable progress of a nation, the choice of building materials that have reduced environmental burdens is helpful.

The purpose of these studies is to justify the feasibility of recycling different types of industrial waste instead of conventional expensive raw materials in production of environmentally friendly aerated concrete with required construction and operational properties. The impact of wastes from various industries on the environmental condition of affected areas, as well as the results of their environmental assessment were analyzed to determine whether these wastes could be used in production of high-performance building materials. The assessment of industrial wastes in aerated concrete production suggests that industrial wastes of hazard class IV can be recycled to produce aerated concrete. An environmentally friendly method for large-scale waste recycling, including a two-step environmentally sustainable mechanism, was developed. The basic quality indicators of the modified aerated concrete proved that the environmental safety could be enhanced by strengthening the structure, increasing its uniformity and improving thermal insulation properties. The modified non-autoclaved aerated concrete products with improved physical and operational properties were developed. They have the following properties: density – D700; class of concrete – B3.5; thermal transmittance coefficient – 0.143 W/(m·°C); frost resistance – F75.

The Impact

In recent years, the awareness of sustainable construction has increasingly risen in countries around the world, with the main goal being to avoid depleting energy resources and raw materials and to greatly reduce carbon emissions. Therefore, the selection of eco-friendly building materials becomes a difficult task and choosing the best construction strategy is a complicated process. Most of the studies of the building material selection often focus on optimizing material-related green building scores with budget constraints based on the environmental impacts of those materials. However, these studies do not pay attention to the impact of sustainable materials on two important aspects of a project: The initial investment cost and the total labor-working days. Hence, this study developed a model that optimizes a material mix for buildings considering the building budget, total labor-working days, and material-related green building scores. A case study in Vietnam was conducted to illustrate the effectiveness of the proposed model. This proposed model provides a guidance for decision-makers in selecting approximate materials for buildings toward sustainability.

Natural stoppers are a magnificent closure for the production of aging wines and unique wines, whose application is limited by the availability of raw materials and more specifically of cork sheets of different thickness and quality. The growing demand for quality wine bottle closures leads to the search for alternative stopper production. The two-piece stopper is an alternative since it uses non-usable plates in a conventional way for the production of quality caps. The present study has analyzed the impact of the manufacture of these two-piece stoppers using different methodologies and for different dimensions by developing an LCA (Life Cycle Assessment), concluding that the process phases of the plate, its boiling, and its stabilization, are the phases with the greatest impact. Likewise, it is detected that the impacts in all phases are relatively similar (for one kg of net cork produced), although the volumetric difference between these stoppers represents a significant difference in impacts for each unit produced.

This article summarizes the arguments within the scientific discussion on the issue of using mining machines and their life cycle. The main goal of the article is to investigate the impact of a combination of mobile and stationary mining machines and their optimal distribution in the mining process to increase the efficiency of mining and processing of raw materials. The following methods of research were focused on the use of technical indicators for the valuation efficiency of the mining process: a simulation method was used for the distribution of mining machines, comparison analysis was used for the real and past state of mining machines, and a decision tree was used as managerial instrument for optimal alternatives of mining machines. The research empirically confirms and theoretically proves that optimal distribution of mining machines and machine parks is very important for mining companies. The benefit of this research for the mining company was the new location of the machines and the combination of stationary production lines and mobile equipment. The optimal layout of the machines reduced the number of conveyor belts and improved the transfer of limestone processing to mobile devices, saving time, which was reflected in transport costs. The results can be useful for other mining companies seeking to create an optimal machine park.
