Sustainability in civil construction: application of an environmental certification process (leed) during the construction phase of a hospital enterprise – rio de janeiro/brazil

Abstract

World history tells us that construction has always existed to meet the immediate and basic needs of man, and, in this time of rapid growth, did not take into consideration construction techniques and environmental preservation. This paper aims to present investigation and diagnosis at the stage of site construction, exploring the environmental impacts caused by construction site, with exposure of some interventions to minimize this effect, integrating the concepts of sustainable construction. Given the historical background of continued environmental degradation caused by human needs, which resulted in serious risks to society, and knowing that more than 60% of solid wastes generated in urban centers are from the construction site, the need arises to develop techniques and solutions to mitigate these impacts. Structure of the research/approaches: The paper is structured in four parts: description of an evolutionary history regarding environmental concern, a sustainable construction issue approach, surveying interference at the stage of site construction, and a case study focusing on environmental sustainability during the site construction phase of an enterprise. Contributions: The characteristics of a sustainable building interfere directly in the relation between man/environment with issues that can be minimized when designing a project, which should be applied from the construction of a building to the end of its life cycle. A sustainable enterprise is not defi ned not only by environmental and social benefi ts in its use and operation but also in its construction.

Processo de Mudança para uma Orientação Sustentável: Análise das Capacidades Adaptativas de Três Empresas Construtoras de Santa Maria-RS

“…Esse posicionamento estaria condizente com a recomendação em Le at al. (2012) e Vazquez et al (2013) de inclusão de disciplinas que abordam a construção sustentável para haver melhoria na formação de profissionais. Nesse sentido, Hogan e Coote (2014), que aplicaram o modelo de Schein (1992) de cultura organizacional à inovação, propõem que valores são críticos para o desenvolvimento de comportamentos desejáveis e a formação da cultura organizacional.…”

“…De acordo com Vazquez et al (2013), ainda há muito a ser adotado e aprendido pela indústria de construção a respeito de sustentabilidade, mas resultados positivos na redução da degradação ambiental e geração de economia no consumo de recursos estão a conduzir essas mudanças. Novas tecnologias podem ser cada vez mais encontradas no mercado para ajudar nessas questões, e com um menor grau de diferenciação de preços.…”

“…Outros estudos têm destacado a necessidade de melhorias na formação de engenheiros e no treinamento de técnicos com a inclusão de disciplinas nas instituições de ensino que abordam o assunto (Le et al, 2012). Vazquez et al (2013) reforçam essa posição em seu argumento em prol de melhorias na adoção dos conceitos de sustentabilidade no setor da construção civil.…”

A Quantitative Method for Prediction of Environmental Aspects in Construction Sites of Residential Buildings

“…These emissions can be easily dispersed depending on factors such as meteorological conditions, the layout of the site, and distances between the storage areas and places of the activities [55]. Among the sources of pollution are the various construction activities and their machinery, and vehicles [56].…”

Sustainability of reinforced concrete frame structures – a case study

“…Sustainability of a structure is influenced by the established static scheme, the type of the materials used, the ratios and quantities of the embedded materials, by the proposed realisation processes, the service period and eventual maintenance, and the possible recycling of the demolished structure. Studies performed by Puskas and Virag [8], Danatzko et al [9] and others [10,11] are emphasising that in design phase the chosen structural systems have high influence on the sustainability of the whole project, but the embedded material qualities and quantities are having the largest influence on the sustainability of the structure. In case of reinforced concrete frame structure ( Fig.…”
