This study aims to develop a methodology for the selection of sustainable building materials for the reduction of embodied and operational energy for a complex infrastructure transportation project, i.e., elevated metro rail station of Ahmedabad, India by application of building information modelling (BIM) and factor comparison method (FCM). Evaluation of the alternative building materials and designs to obtain the best energy efficiency has been carried out using Revit Architecture 2018 and Green Building Studio. The achieved average embodied energy savings is about 73%, which is by the suggested alternative materials instead of existing ones. By application of FCM, which is a multi-criteria decision making (MCDM) technique, it has been observed that the polished Kota-stone flooring, stone-floor tile cladding, toughened fibre-glass ceiling and insulated fibre-glass door appear to be the most feasible sustainable material for flooring, wall cladding, ceiling, openings and fenestrations for the design of the metro rail station box in Ahmedabad, India. This study contributes significant knowledge in the field by highlighting the application of BIM as a tool for sustainable development and recommends a few alternate building materials and sustainable designs which would result in the reduction of energy usage for the metro-rail-station and other building structures leading to a sustainable future.

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.

Abstract Building activity has recently led to the deterioration of environment and has become unsustainable. Several strategies have been introduced in order to minimize consumption of energy and resulting CO2 emissions having their origin in the operational phase. But also other stages of Life Cycle should are important to identify the overall environmental impact of construction sector. In this paper 5 similar Slovak buildings (family houses) were analyzed in terms of environmental performance of building materials used for their structures. Evaluation included the weight of used materials, embodied energy and embodied CO2 and SO2 emissions. Analysis has proven that the selection of building materials is an important factor which influences the environmental profile. Findings of the case study indicated that materials like concrete, ceramic or thermal insulation materials based on polystyrene and mineral wool are ones with the most negative environmental impact.

Numerous scientific researches show that the activities connected with building materials produce significant negative environmental effects. Observed from the point of architecture, the use of building materials is found to be one of the critical factors of environmental pollution and degradation. The purpose of introducing architectural interventions, including proper selection, is the reduction of the negative environmental impact of building materials. The aim of this paper is to define, from the ecological aspect, basic principles for the selection of building materials. First, principles were defined through the all - inclusive analysis of every phase in the life cycle of building materials. Summing categories: embodied energy and embodied CO2 are discussed afterwards. In the order to simplify the procedure of arriving at a decision, priorities in selection were emphasized in every separate segment of this paper. The selection of building materials with reduced negative environmental impact (ecologically correct building materials) is one of the key decisions in the process of designing ecologically correct buildings.

Buildings account for approximately one third of the total worldwide energy emissions, of which approximately a quarter can be attributed to the embodied energy of the building. Current UK legislation for low-energy homes is only concerned with operational energy. Embodied energy, and carbon, is not currently considered but over the design life of an average building is expected to make a significant contribution to the total whole life energy used. Earthen building materials contribute to reduce energy consumption in use through their passive regulation of temperature and humidity. In addition, there can also be significant embodied energy savings compared to other materials. Traditional methods of earthen construction, using locally sourced materials and manual labour require minimal energy for the transport and construction. A greater uptake of earth construction is likely to come from modern innovations such as industrialised manufacture. Extruded fired brick manufacturing processes has the potential to produce a high quality, low cost and low energy product suitable for the mainstream construction sector in both developed and developing nations. By not firing the extruded clay bricks, an embodied energy saving of 86% can be achieved, compared to fired clay, and 25% compared to concrete blocks. However, there are limitations to the structural use of unstabilised earth bricks due to the loss of strength under high moisture content conditions. The use of traditional and novel stabilisation methods can be adopted to address the concerns over strength and durability. Cement and lime are widely used in some countries, but both significantly increase material embodied energy and carbon and can inhibit passive humidity regulation. The paper presents results from a study of the embodied energy of various stabilisers used for unfired clay materials. The Global Warming Potential (GWP) is a measure of the equivalent carbon dioxide that allows for the relative weightings of damaging greenhouse gasses. Both the embodied energy and the GWP figures of various stabilisers are compared and discussed. The conclusion of the work is that there is a maximum quantity of stabiliser than should be used. Typically the quantities of stabiliser are quoted as the amount that gives the maximum strength, but this should take account of not only strength but the environmental impact of achieving the improvement.

Present World

The present world cannot be imagined without construction industry. On other hand we are not able to prevent impact of construction on the environment due to usage of its key component that is cement, which plays a greater role in the emission of greenhouse gases. Every tonne of Ordinary Portland Cement (OPC) that is produced releases on average a similar amount of CO2into the atmosphere, or in total roughly 6% of all man-made carbon emissions. One of the purposes of research should be to lower the amount of cement during construction without compromising the quality of building structure. Microbial metabolic activities often contribute to selective cementation by biomineralization. In the present study, a novel microbial based low energy green building material based on microbially induced calcium carbonate precipitation (MICP) has been reported that is known as “biocement”. Biocement has enormous potential and usage in building materials and structures with potential to partially replace the cement. The research demonstrates that production of biocement can enhance the durability of building structures in addition to have least impact on the environment.
