Emission Of Greenhouse Gases

Buildings could be led to adverse impacts on environment, such as generation of construction and demolition waste, and emission of greenhouse gases (GHG). Therefore, promotion on development of green buildings is in need. With the increasing awareness in sustainable development, various rating tools are promoted to evaluate the performance of green buildings. Nowadays, these tools function as a guideline for green building development. There are various green building rating tools developed worldwide, and various countries follow different rules, incentives and regulations. However, despite of promotion of green building rating tools, environmental issues from buildings are still significant in Australia. This research compared green building rating tools in Australia and other countries or regions around the world. This research found that rating tools in Australia lack of (1) mandatory criteria and (2) regulations and incentives. This paper recommended that governmental incentives should be promoted.

Building Project

Sustainable development in the construction industry demands implementation of a green rating procedure and certification to assess building. The rating tools set benchmarks for green measures for constructing and use of buildings to reduce their negative impacts on environment thereby making it more sustainable. In this paper, Rating systems and certifications across the globe are studied and compared to give a clear understanding of all for any green building project to be evaluated upon. There are 18 major certifications and 18 rating systems all over the world, however in India there are three rating systems which are mostly used viz. IGBC, GRIHA, LEED. It is recommended that a more simple system is needed for enhancing the participation of all stakeholders in Green building construction thereby leading to sustainable development.

Emission Of Greenhouse Gases

In many parts of the world, drinking water is not available except through desalination. Most of these areas have an abundance of solar energy, with few cloudy periods. Energy is required for desalination and for producing electricity. Traditionally this energy has been supplied by fossil fuels. However, even in those parts of the world that have abundant fossil fuels, using them for these purposes is being discouraged for two reasons: 1) the emission of greenhouse gases from combustion of fossil fuels, and 2) the higher value of fossil fuels when used for transportation. Nuclear power and solar power are both proposed as replacements for fossil fuels in these locations. Both of these energy systems have high capital costs, and negligible fuel costs (zero for solar) Instead of these two primary forms of energy competing, this paper shows how they can compliment each other, especially where a significant part of the electricity demand is used for desalination.

Demolition Waste

In Pakistan, construction and demolition waste(CDW) is generated in voluminous amount each year. CDW iswidely ill-handled and ultimately fed to landfills causing harm tothe already alarming environmental conditions. In order tosearch for the solution of this drastic matter, a study was done,which is explained in this paper. This paper presents the studydone at a demolition site near Karachi, in Sindh while thedemolition works were being carried out. At the site there wereold barracks which were being demolished. Before the demolitionworks were commenced, the site was surveyed and structuralcomponents of the barracks were counted and their dimensionswere measured. When the demolition was over, the demolishedwaste was calculated which comprised of concrete and masonryrubble, steel round bars, steel doors, steel windows, steel ceiling,steel girders, steel main gate, and plastic water tank. This studyinterpreted that construction and demolition (C&D) works wereprogressing considering the works’ deadline and the clients’requirements but the ecosystem’s ecology and the environmentalhealth were not taken into account. Recommendations are madeto handle CDW properly throughout its lifecycle. Theserecommendations aim to provide technological and logicalsolutions to grip CDW. The recommendations include wastereduction and reusing waste, life cycle assessment and costing,environmental and economic impact, material flow analysis, andadvanced computerized-tools.

Global Goal

Reuse of materials is a significant global goal that contributes to sustainable development. Polymer-specific plastic identification from the waste stream is examined in this study to achieve environmentally optimistic reuse of plastic material in secondary applications. Two diverse waste streams, 86.11 kg of construction and demolition waste (CDW) plastic and 57.74 kg of mechanically sorted plastic, were analyzed by using a handheld tool whose identification technology was based on the near-infrared spectrum. The study indicates a significant effect of human and single fraction on manual separation. The polymer composition in the plastic waste stream varied depending on the source, but the most common plastic grades, polypropylene (PP) and polyethylene (PE), were represented in every waste stream. The waste stream also included unidentified and unfavorable wastes, which indicates that identification of the plastic fractions is needed and more studies should be done in this field in the future.

The Cost

Green buildings have benefits for the environment, which has been acknowledged by the vast majority of building professionals. LEED is one of the most recognized green building certification systems in the world. However, issues related to financial aspects of the entire process and LEED certification may be significant and constitutes new financial burdens to the cost of the projects. After a diligent literature research, main issues related to cost can be identified under four major categories such as; cost of the certification process, scarcity of insurance solutions, rental due to delay related to green construction procedures and conditions, and failure to use of financial incentives (tax/loan discounts, low financing rates) because of delays or lower certification levels than expected throughout the LEED certification. This study focuses on the assessment of professionals’ experiences about the financial and economical risks green buildings and their impacts on cost by identifying the most common drawbacks and evaluate relevant precautions against them. Analysis results show that high cost of certification process is one of the concerns for the majority of the professionals. Rental loss due to delay related to green construction procedures and conditions, costs related to certification, documentation, practices and design are found as the other risk factors in the study. Proper allocation of such risks in contract documents and special insurance products with appropriate endorsements could be used to mitigate related risks.

Chain of the life cycle of construction expanded polystyrene (production – construction application – liquidation after the end of the life cycle) is connected with significant energy consumption, consumption of oil, and production of considerable volume of construction and demolition waste. A sustained effort has been applied to increase effectiveness and to reduce the ecology waste from this process. Tools of this effort are the market mechanisms and legislation in the area of environmental issues and also the societal changes. Their consequences are especially the changes in structure of polystyrene producers and their production technologies, changes in composition of polystyrene and modification of procedures for handling the construction and demolition waste.

Negative Side Effects

The whole world is constantly changing. We are going through a period marked by challenges that will directly influence humanity. The phenomenon of globalization has come with benefits but also with negative side effects, creating uncertainties and inequalities in social, economic, political and environmental. The great crisis of 2008-2009 had a major negative impact on the economies of the world, and it is still difficult to recover the losses caused. At present, there is an increased emphasis on social and environmental issues, aiming as much as possible towards a sustainable society. With a decade left, the world is working to meet the 17 United Nations Sustainable Development Goals by 2030. But the challenge is huge, given the current difficult geopolitical and geoeconomic context. The requirements for sustainable development need excellence in innovation. This paper aims to present Romania’s current position on the European map of innovation, as well as perspectives that can influence the future evolution of the national economy in the context of sustainable development.
