Green Building Technologies

Energies

Recent advancements in green building technologies (GBTs) have grown substantially, as an outcome of the environmental, economic and societal benefits. It has the potential to move toward sustainable development, specifically related to climate change. In GBTs, the main objective is to use energy, water and other resources in a balanced way, without using them extensively. This will improve the environmental conditions. Green buildings (GBs) are beneficial when it comes to energy consumption and emissions; low maintenance and operation costs; boosting health and productivity; etc. There is a lack of a critical review of the past or present research work in the area of the Green Building Technology (GBT) sector to identify the future roadmap for sustainable green building technologies. A critical review, with the help of proper research methodology, was identified. The scope of this study is to analyze the existing work on different issues, and find different key issues in green buil...

Environmental considerations have called for new developments in building technologies to bridge the gap between this need for lower impacts on the environment and ever increasing comfort. These developments were generally directed at the reduction of the energy consumption during operations. While this was indeed a mandatory first step, complete environmental life cycle analysis raises new questions. For instance, for a typical low thermal energy consumption building, the embodied energy of construction materials now becomes an important component of the environmental footprint. In addition, the usual practice in life cycle analysis now appears to call for some adaptation-due to variable parameters in time-to be implemented successfully in building analysis. These issues bring new challenges to reach the goal of integrated design, construction, commissioning, operation, maintenance, and decommissioning of sustainable buildings.

Global environmental issue of climate change is caused by the release of greenhouse gases into the atmosphere and it has been recognized as one of the greatest threats of the 21 st century. The consumption of energy in India is rising due to rapid urbanization, population explosion, intensive growth of information technology and related businesses. Buildings are the prime energy consumers in modern cities accounting up to 40% energy consumption. Their consumption can largely be cut back through improving efficiency, which is an effective means to reduce greenhouse gas emissions and slow down depletion of non-renewable energy resources.

Buildings are estimated to account for more than a third of the world's resources in construction, 40 percent of global energy (including embodied energy), 12 percent of fresh water use, and generate 40 percent of greenhouse gases (GHGs) emissions and make up 40 percent of waste to landfill. The worldwide concerns for the impending resource crunch and the dangers of global warming, and the understanding of the role that buildings can play to contribute positively to the economy, energy security, human health and the environment have led to a quiet green building revolution around the globe over the last decade. Energy plays a vital role over the life cycle of a building, hence sustainable buildings and energy refurbishments in buildings hold enormous potential for energy saving and a reduction of greenhouse gas emissions. The main target of this paper is to find out the effectiveness and sustainability in green building design implementations which evaluates energy performances. In addition, the paper explains the key feature of the green building as well as its usefulness, current challenges and barriers.

The phenomena of climate change and global warming present us with numerous challenges today. Several scientific studies indicate that the construction industry is largely responsible for this state of affairs. Inappropriate technologies, equipment and building materials are used in construction, which are harmful to the environment and human health. Therefore, these issues need to be addressed immediately. Due to global warming, engineers and technologists have become increasingly aware of the environmental impact of the construction sector in recent decades. They propose the introduction of sustainable or green design principles to mitigate the above threats. Sustainable building design aims to transition from harmful to non-harmful materials and technologies in construction. The aim of this study is to investigate environmentally friendly technologies, materials and standards that can reduce the energy and resource consumption of buildings, leading to a positive outcome for people, society and the environment. Compared to conventional buildings, sustainable buildings are more environmentally and people friendly and use key resources more efficiently. This study also shows how sustainable buildings can benefit people and the environment while reducing damage to nature.

Green building is one of measures been put forward to mitigate significant impacts of the building stock on the environment, society and economy. However, there is lack of a systematic review of this large number of studies that is critical for the future endeavor. The last decades have witnessed rapid growing number of studies on green building. This paper reports a critical review of the existing body of knowledge of researches related to green building. The common research themes and methodology were identified. These common themes are the definition and scope of green building; quantification of benefits of green buildings compared to conventional buildings; and various approaches to achieve green buildings. It is found that the existing studies played predominately focus on the environmental aspect of green building. Other dimensions of sustainability of green building, especially the social sustainability is largely overlooked. Future research opportunities were identified such as effects of climatic conditions on the effectiveness of green building assessment tools, validation of real performance of green buildings, unique demands of specific population, and future proofing.

The goal of this study was to look into the potential benefits and drawbacks of implementing a global green building grading system. Academic studies that address the desire for sustainability through green buildings require a unified future research path. Future topics of green building research, according to the findings, include fully automated BIM rating system integration, collaboration and intellectual property challenges, and the inflexible contractual arrangements required for multiple party engagement. We looked into the necessity for LEED certification, which would compel buildings with higher environmental impacts to achieve higher levels of energy performance depending on those impacts.

In the present era of growing population there is a parallel demand for the construction industry as well as fertile land which is a finite resource. To suffice this need a large number of construction companies are coming up. In this process the deterioration of land, environment, healthy life style and safety is overlooked. The use of land and resources for constructions are becoming endless and is against sustainable development. In the present period of water scarcity the wastage of water and energy which is indirectly related to water is bothersome. Therefore in concern to the above problem, the main aim is to evaluate the impact of overlooked areas and study the incorporation of green building techniques into constructions that can help address National concerns like water efficiency, energy efficiency, reduction in fossil fuel use, handling of consumer waste and conserving natural resources. Most importantly, these concepts can enhance occupant health and well-being, which is...
