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

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

Proposta de captação de água de chuva de para fins não potáveis em projetos residenciais

Water is an economic, strategic and social valuable resource of the utmost importance to society. This renewable natural resource is increasingly scarce with the growing of populations, industries and agriculture, in addition to the pollution surface and underground water and the waste have aggravated this situation. Investments in the sector of water resources so that this resource meets in quantity and quality the demand from its multiple uses, represent a significant portion of national and regional budgets. Therefore, the use of alternative sources of water capture can reduce the pressure on conventional public water supply systems. In this work was designed and executed a rain water collection system to a residence in the city of Barueri (SP), which can be applied to other residences. In this system, the rooftop of the residence was used as the waterproof and capture area. The gutter and the PVC conductors were used for driving the water to two connected reservoirs. The stored water was designed to address activities that are not potable, such as washing clothes and external areas and garden irrigation. The system showed economic viability, with 34-month return of investment time, wherein after that period, in addition to environmental and social benefits derived from the implementation of the project, the economy made with the payment of public supply rates should be considered. This rainwater capture system is inexpensive and uses materials available in the market. Therefore, its application to a greater number of households should be encouraged as a measure of sustainable water management

Viabilidade técnica e econômica do superadobe na construção de casas populares

The need for affordable housing and the high cost of today's building materials make necessary to look for useful and affordable technologies for these house buildings. In this context, this study aimed to evaluate the technical and economic feasibility of construction technology called Earthbag for use in public housing. Technical assessments were based on Kiffmeyer and Hunter's book (2004), academics dissertations and construction standards for the technology. The result allowed a positive evaluation towards the feasibility proposal and showing the possibility of replace the use of structural concrete blocks in public housing. The economic viability was performed an economical compared to a project Housing Project Bom Retiro 2 with one of Earthbag which have been shown considerable savings between the techniques. For the construction of masonry, build with purchased sand, 13% lower budget was found in comparison of a concrete masonry block. With the use of sand from the work site itself, there is a saving of 18%. Although earthbag has proven to be a technically and economically feasible for application in the construction of affordable housing, the shortage of technical and scientific studies and Brazilian regulations on this technology has limited its large-scale use

Gerenciamento de resíduos da construção civil: análise e atualização dos estudos realizados na UNESP-FEG para o município de Guaratinguetá

The construction industry is a large consumer of natural resources and one of the largest generators of residues with significant impacts on the environment. Because of the large production of Construction Industry Residues (RCC), it is essential reliable and updated information about generation, composition and classification sources of these residues, especially for management, recycling and final disposal. RCC represent the most part of solid residues generated in a city. In this way, the management of these residues is an issue that is gaining increasing importance in the Brazilian scenario, since the legal and society requirements to internalize the sustainability in the construction process - since the extraction, use, wastage savings, reutilization until the appropriate discard has been increasing in the last years. The present work objective is updating the quantities produced and collected in Guaratinguetá-SP, based on data collected with the municipal administrative entities that act direct or indirectly in the RCC management, elaborate a detailed bibliographic review, with special attention to the graduate works that were realized in FEG about this theme. With this material, scenarios to a better adequacy of the administrative structure to managements RCC activities, as well as was suggested actions to achieve these scenarios

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.
