Nowadays, the sustainability of buildings has an extreme importance. This concept goes towards the European aims of the Program Horizon 2020, which concerns about the reduction of the environmental impacts through such aspects as the energy efficiency and renewable technologies, among others. Sustainability is an extremely broad concept but, in this work, it is intended to include the concept of sustainability in buildings. Within the concept that aims the integration of environmental, social and economic levels towards the preservation of the planet and the integrity of the users, there are, currently, several types of tools of environmental certification that are applicable to the construction industry (LEED, BREEAM, DGNB, SBTool, among others). Within this context, it is highlighted the tool SBTool (Sustainable Building Tool) that is employed in several countries and can be subject to review in institutions of basic education, which are the base for the formation of the critical masses and for the development of a country. The main aim of this research is to select indicators that can be used in a methodology for sustainability assessment (SBTool) of school buildings in Portugal and in Brazil. In order to achieve it, it will also be analyzed other methodologies that already incorporate parameters directly related with the schools environment, such as BREEAMor LEED.

Analysis and selection of indicators for a sustainability assessment method for school buildings based on SBTool ‐ PT

In a context in which public constructions represent a significant portion of many countries' construction activities, assessing these works' sustainability plays a fundamental role in reducing social, economic, and environmental impacts and encouraging the use of more sustainable construction practices. There are currently several assessment systems and methods with different scopes and approaches. However, few consider the specificities of public works. This article proposes a structured set of indicators for assessing public works' sustainability, based on the criteria proposed by the leading researchers working on the topic and those covered by the LEED, SBTool, BREEAM, and Green Star assessment tools. After extensive and detailed bibliographic research, the criteria were categorized, reordered, and unified, resulting in a structure composed of nine categories that add 214 criteria, which can be adapted to the particularities of different types of work, to any region, and at any stage of the cycle of life. The proposed structure, being more comprehensive and flexible than the most used tools, increases public managers' capacity to assess the real situation, understand the right needs, establish changes, and direct their efforts to make their works more sustainable.

Criteria for the assessment of sustainability of public constructions

Enhancing the sustainability of public works has been a key agenda in recent years for many governmental organizations. Public works contribute significantly to a large portion of engineering works and have great potential to impact the sustainability of cities. Thus, evaluating the sustainability of these projects is highly relevant, mainly regarding their impacts on environmental, social, and economic aspects. There are currently assessment systems and methods with different scopes and approaches. Yet, there remains uncertainty when it comes to considering public works’ sustainability and how useful criteria can be incorporated into the proposed assessment tasks to ensure such a goal. This study contributes to filling this gap by developing, through an extensive and detailed bibliographic research, a flexible and comprehensive framework composed of 214 criteria distributed across nine categories that measure the degree of sustainability of public works, with emphasis on economic, social and environmental goals. The proposed framework can act as a practical tool, functioning as a checklist applicable to all types of public construction works, and at any stage of the lifecycle. Evaluation of the framework by professionals indicated its suitability when encompassing sustainability objectives, its viability, and its ease of use.

Sustainable Assessment of Public Works through a Multi-Criteria Framework

A construcao civil e uma atividade que gera impactos ao meio ambiente, muitas vezes negativos. As obras contratadas pelo Governo Federal representam um grande volume e necessitam de um planejamento adequado do ambiente a ser construido, visando causar o menor impacto possivel nos ecossistemas naturais. Algumas iniciativas do governo para estabelecer diretrizes de sustentabilidade foram implantadas, como a Instrucao Normativa 01/2010, porem na pratica esta instrucao ainda e pouco utilizada. A realizacao desta pesquisa justificou-se pela necessidade de melhorar o desempenho ambiental das edificacoes publicas a fim de reduzir o impacto causado no meio ambiente. Com base em tres reconhecidas certificacoes ambientais para edificacoes, por meio de matrizes de comparacao, foram relacionados as suas categorias e os criterios a fim de verificar quais atendem as diretrizes indicadas na IN 01/2010 e quais sao os mais importantes e que devem estar presentes para complementar o modelo proposto. O sistema desenvolvido, denominado SAAPE, e composto por seis categorias de desempenho ambiental, que se desdobram em 44 pontos a serem cumpridos. O sistema foi aplicado em tres projetos da Universidade Federal do Parana, para validar sua aplicabilidade e para verificar a situacao dos projetos elaborados para este orgao. Os resultados obtidos mostram que em nenhuma das edificacoes pesquisadas foi possivel obter a pontuacao minima, que e de 18 pontos, estando entre 14 e 15 pontos. Porem, ainda que de forma embrionaria, algumas solucoes que buscam reducao nos impactos ja estao sendo adotadas. Posto isso em pratica, o sistema elaborado visa auxiliar os gestores publicos, arquitetos e engenheiros para que, durante a preparacao dos projetos de obras publicas, respeitem os criterios de sustentabilidade ambiental dispostos na IN 01/2010, alem de fornecer oportunidades de melhorias da qualidade em relacao aos aspectos de sustentabilidade na fase de concepcao de projetos.
