Benefícios na execução de uma obra sustentável em contrapartida aos métodos tradicionais da construção civil

The civil construction sector in Brazil is, simultaneously, a necessity that drives the economy and an evil that degrades the environment. Simple choices adopted in an enterprise can make big difference in harm caused by constructive practices, minimizing its harmful to the environment and making it sustainable. These choices, however, involve the use of materials and techniques often unknown by the builders, since the construction industry is very traditional. Even worse, the eco-friendly materials and sustainable techniques also face another obstacle to its use: the prejudice. Builders and customers prefer traditional methods to sustain belief that they present lower quality and higher price. This work raises awareness of the urgency with traditional methods must be overridden, showing practical and simple ways for this replacement, as well as confirm the quality equal to or even higher in the use of alternative materials and techniques, without addition in cost. Thus, the benefits are generated for all parties involved, from builders to residents

Projeto de condomínio residencial sustentável

It's devised in this work the starting project for the implementation of a residential condominium, focused in the use of technics and technologies to attain sustainability, also stretching to the pilot project for the model house. It's highlighted the methods for exploitation and reuse of water, energy conservation and reduction of environmental impacts. The proposal is to demonstrate the possibility of the use of simple, but effective, ecology technics to make an environmentally sustainable and economically viable project. The main motivators for this work is the growing hydric crisis faced by São Paulo state and the unpaired importance of the sustainability concept as the fundamental term to surmount the challenge of supplying the needs of the current generation without jeopardizing the future of the next generations

Aproveitamento da água de chuva para fins não potáveis para um condomínio sustentável: um estudo de caso

The End of Course Work this aims, the hydrological cycle of water on our planet, and explain about its importance in the lives of living beings, finally, carry out a detailed analysis regarding the financial feasibility of implementing a system Shauer sustainable in the condominium, the first being the pickup of river water, which will use a reservoir for capitation and filtering, a reservoir for water storage filtered and pumps that will redirects it to outside faucets and toilets use in residences

Certificações ambientais para construções civis

Over the recent human history within the last centuries the environmental degradation has been accumulating and growing rampantly causing effects today easily perceived by all. Because of this, today we can say that there is almost a consensus among the world population's concern with the environment in order to seek to minimize these effects immediately in addition to not aggravate the situation for future generations. Thus today it is common to find a wide range of products with this ideal of sustainable commitment in the various commercial areas. The construction industry has a responsibility to be a major cause of these impacts to the environment, so it is also one of the main vectors able to mitigate the degradation of the environment. In order to encourage, oversee and promote the sustainable attitudes within the construction area emerged environmental certifications. In this work it's exposed some of the major certifications for civilian buildings, highlighting the Selo Azul da Caixa that appears as a good choice focused on the Brazilian reality

Gás natural no panorama brasileiro e um estudo de caso no setor automotivo

The intended purpose of this paper is to present the main aspects of natural gas applied to the public transportation as well as the environmental, economical and technical impacts in this sector. Also it is given specific information to be considered when comparing natural gas to other fuels, specially the diesel. At this point is presented the types of internal combustion engines (Otto and Diesel cycle) and which type is used in each vehicle. Moreover, it is presented the main standards pollutant emission (Euro, US and Proconve) with a brief explanation of the tests made in order to approve the engines. This paper is focused on heavy duty vehicles. Also in this paper is exposed the economic impact due to the natural gas use in the public transportation fleet. In addition is presented a real case (of Berlin) and an estimative to a Brazilian city, presenting the potential of natural gas as vehicular fuel in Brazil, as well as financial and environmental aspects of the substitution

EDiferentes tipologias de edificação e o ser sustentável mediante o LEED e o CBCS

The principles and dimensions of sustainability concept is increasingly gaining ground within the building industry. Over the past decades, its applicability within the different environments and for different buildings typologies have been study to attend better the present populations and future generations. It is within this scenario that international certifications started to appear. The most famous and developed one being LEED certification system. In Brazil, as a support to the certification and also sustainability practices and conducts, was founded the Brazilian Council for Sustainable Construction (CBCS). The council and the certifications have the objective to disseminate and generate awareness to reduce energy and water consumption, aiming for life quality. Many constructions around de country have already the international certification, which also boost the rise of national certifications with specific criteria for the national context. However, such certificates are mainly destiny for medium and high standard buildings, often as a commercial advantage to explain the high costs. The purpose of this work is to be able to define what is being sustainable in the construction industry, taking for basis, LEED and CBCS. In addition, since there is a significant increase in the production of Housing Social Interest, the other angles will be to analyze how to apply the practices and sustainable technologies for low-cost projects with the objective to balance the three dimensions of sustainability: environmental, social and economics.

Preparation of Coated Microtools for Electrochemical Machining Applications

PREPARATION OF COATED MICROTOOLS FOR ELECTROCHEMICAL MACHINING APPLICATIONS Ajaya K. Swain, M.S. University of Nebraska, 2010 Advisor: K.P. Rajurkar Coated tools have improved the performance of both traditional and nontraditional machining processes and have resulted in higher material removal, better surface finish, and increased wear resistance. However, a study on the performance of coated tools in micromachining has not yet been adequately conducted. One possible reason is the difficulties associated with the preparation of coated microtools. Besides the technical requirement, economic and environmental aspects of the material and the coating technique used also play a significant role in coating microtools. This, in fact, restricts the range of coating materials and the type of coating process. Handling is another major issue in case of microtools purely because of their miniature size. This research focuses on the preparation of coated microtools for pulse electrochemical machining by electrodeposition. The motivation of this research is derived from the fact that although there were reports of improved machining by using insulating coatings on ECM tools, particularly in ECM drilling operations, not much literature was found relating to use of metallic coating materials in other ECM process types. An ideal ECM tool should be good thermal and electrical conductor, corrosion resistant, electrochemically stable, and stiff enough to withstand electrolyte pressure. Tungsten has almost all the properties desired in an ECM tool material except being electrochemically unstable. Tungsten can be oxidized during machining resulting in poor machining quality. Electrochemical stability of a tungsten ECM tool can be improved by electroplating it with nickel which has superior electrochemical resistance. Moreover, a tungsten tool can be coated in situ reducing the tool handling and breakage frequency. The tungsten microtool was electroplated with nickel with direct and pulse current. The effect of the various input parameters on the coating characteristics was studied and performance of the coated microtool was evaluated in pulse ECM. The coated tool removed more material (about 28%) than the uncoated tool under similar conditions and was more electrochemical stable. It was concluded that nickel coated tungsten microtool can improve the pulse ECM performance.
