Considerando que a construção civil é responsável por significativa quantidade das emissões de poluentes na atmosfera e danos gerais causados ao meio ambiente, esta dissertação se concentra nos elementos da construção sustentável, focando nos requisitos dos selos de certificações ambientais presentes no Brasil. O objetivo deste trabalho é definir diretrizes para projetos sustentáveis, baseando-se nas categorias e critérios de avaliação ambiental dos selos mais utilizados no Brasil: LEED, AQUA e Selo Casa Azul, considerando a contribuição para os quatro sistemas de suporte à vida na Terra, são eles: Atmosfera, Água, Solo e Seres Vivos. Além disso, uma breve análise das práticas do mercado nos permite traçar o panorama da construção enquanto sustentável. O método utilizado se baseia numa revisão bibliográfica sobre sustentabilidade e seus sistemas de avaliação no ambiente construído no primeiro momento. O desenvolvimento da pesquisa tem como base metodológica os fundamentos da Design Science Research, como forma de geração de conhecimento. É feita uma análise qualitativa das certificações citadas a fim de sintetizá-las em diretrizes. Como resultado, as diretrizes geradas são contrastadas com as práticas de mercado, permitindo-nos quantificar o nível da sustentabilidade no nosso ambiente construído. Esta dissertação contribui para o aprimoramento da gestão sustentável do ambiente construído, assim como para a conscientização da urgente necessidade da sustentabilidade neste meio. / Sustainable development, despite being recurring theme in academic, scientific and political meetings, walks slowly in regard to the conditions of the planet Earth. Whereas the construction industry is responsible for a significant amount of pollutant emissions in the atmosphere and general damage to the environment, this dissertation concentrates on elements of sustainable construction, focusing on the requirements of environmental certifications in Brazil. The main objective of this work is to define guidelines for sustainable projects, based on the environmental assessment categories and criteria of the most used seals in Brazil: LEED, AQUA and Selo Casa Azul, considering the contribution to the four life support systems on Earth, which are: Atmosphere, Water, Soil and Living Beings. In addition, a brief analysis of market practices allows us to map the landscape of construction as sustainable. The method used is based on a literature review on sustainability and its evaluation systems in the environment built at the first moment. The development of the research is based on the foundations of Design Science Research as a way of generating knowledge. A qualitative analysis of the certifications is made to synthesize them in guidelines. As a result, the guidelines generated are contrasted with market practices, allowing us to quantify the level of sustainability in our built environment. This dissertation contributes to the improvement of the sustainable management of the built environment, as well as to the awareness of the urgent need of sustainability in it.

The Sub-Saharan African country of Ghana is growing at a rapid pace. The construction industry is striving to keep up with the increasing demand for housing and commercial and industrial space while simultaneously protecting the physical environment and social well-being of the country – a challenge becoming known in the industry as ‘sustainable construction.’ This paper proposes a strategic approach to manage these twin challenges, consisting of two parts: a building rating system and a participatory method called multi-stakeholder dialogue. The combination rating system and MSD process was presented to the industry to determine its potential effectiveness in assisting the industry to move towards sustainability. The industry’s response indicates that the proposal could be of value to the industry, with certain noted limitations. This paper describes the rating system-MSD proposal, the industry’s response, and implications for the construction industry in Ghana moving forward

Building Information Modeling (BIM), used by many for building design and construction, and Geographic Information GIS System (GIS), used for city planning, contain large spatial and attribute data which could be used for Lean and green city planning and development. However, there exist a systematic gap and interoperability challenge between BIM and GIS that creates a disjointed workflow between city planning data in GIS and building data in BIM. This hinders the seamless analysis of data between BIM and GIS for lean and green developments. This study targets the creation of a system which integrates BIM and GIS system data. The methods involve the establishment of a novel Environmental Information Modeling (EIM) framework to bridge the gap using Microsoft Visual C#. The application of this framework shows the potential of this concept. The research results provide an opportunity for more analysis for lean and green construction planning, development and management.

One of the important reasons for the choice of the thesis topic are increasing requirements from the persons interested in low-energy, passive or even houses with almost zero energy consumption. During decreasing of the energy demand is within the framework of the idea of sustainable construction not only required to decrease the total energy demand of the buildings, search and solve the critical spots in the building jacketing, but also to use the secondary raw materials as full-value substitutions for commonly used products from the primary raw materials. The thesis tries to contribute to the possible usage of polymeric wastes in building industry. In an early stage of the thesis the main and partial targets together with the consecutive steps leading to their fulfilment were set. Selection of the suitable secondary raw materials, discussion with the specialists, initial sample mixing, finding their thermally – technical characteristics, press mould and fire kiln acquisition was carried out during the stage. The next phase is focused on the application of the products made from the secondary raw materials to the building envelope. The products are moulded according to the thermally – technical properties. Performed moulding approved that the products are fully functional and after reaching the required value of heat conductivity coefficient products eliminate imperfections of the solutions used at present. Strapping product for the threshold door joint is registered at Industrial Property Office of the Czech Republic and at European Patent Office at the same time. Recycled materials put into production represent possibilities how to decrease number of acquired virgin materials, need of primary energy and how to decrease risks connected to the waste disposal. Society is starting positively approaching to the products that are partially or fully produced from the secondary raw materials. Nevertheless, before the products from the recycled materials enter the peop

This thesis investigates the possible utilization of reclaimed bricks within the framework of circular economy (CE) and sustainable construction approaches, with a particular emphasis on Pakistan's construction industry. The research is based on the theoretical foundations of the Triple Bottom Line (TBL) and Resource Efficiency concepts. Qualitative methods were used to collect data, and a thematic framework was employed to analyse the results. The findings indicate that Pakistan's reclaimed brick sector aligns with the principles of the TBL theory, supporting sustainability in its social, economic, and environmental aspects. Through waste reduction, material reuse, and resource conservation, the industry demonstrates its commitment to environmental preservation. Furthermore, it plays a significant role in the economy by providing affordable infrastructure solutions and contributing to the growth of the construction industry. Additionally, the industry promotes social well-being by providing employment opportunities and financial stability. The study illustrates how Pakistan's reclaimed brick operations effectively integrate social, economic, and environmental factors to create a more environmentally friendly built environment. In summary, reclaimed bricks present a sustainable and resource-efficient alternative for the construction industry, in line with the principles of resource efficiency, preserving resources, minimizing waste, and promoting circular economy practices. The adoption of reclaimed bricks can help Pakistan and other countries achieve their sustainability objectives, reduce environmental impact, and construct structures that are longer-lasting and resource-efficient.

En la actualidad, un gran porcentaje de las viviendas construidas en Perú son producto de la autoconstrucción, estas son construidas con materiales inadecuados, presentan deficiencia estructural y se encuentran ubicadas en zonas no aptas para la construcción, lo cual genera peligro a la población. En el primer trimestre del 2017, ocurrió el fenómeno del Niño Costero, en el cual se generaron importantes daños a la población, viviendas, infraestructura vial, servicios básicos y paralización de actividades socio-económicas. Piura fue uno de los departamentos más afectados por el fenómeno del Niño Costero, donde se registraron en total 105 369 viviendas afectadas y destruidas, 889 establecimientos educativos y 240 establecimientos de salud afectados, 189 790 km de caminos rurales, 1377 km de carreteras afectados y destruidos, y 27 puentes destruidos. Hasta la fecha, las obras e intervenciones de reconstrucción y soluciones de vivienda, no se han ejecutado según lo planificado, motivo por el cual, existe una gran cantidad de familias damnificadas que esperan acceder a una vivienda segura. En la presente investigación, se desarrolló la propuesta de diseño general de un módulo de vivienda sostenible con el objetivo de implementar y valorar la construcción de módulos de vivienda sostenibles en el distrito de Sondorillo - Huancabamba - Piura, basado en la Construcción Vernácula a través del uso de materiales eficientes según los criterios establecidos en el Reglamento Nacional de Edificaciones.

Yes / Geopolymer concrete is a promising candidate to replace conventional concrete as geopolymer concrete depends on alkali-activated binders instead of Portland cement. The elimination of cement from the mixture results in the reduction of the greenhouse gas release. From the literature, it is known that the micro-scale characteristics of the geopolymer concrete are similar to its counterparts. However, the structural performance of geopolymer elements should be investigated in detail. Therefore, in this study, the structural performance of reinforced geopolymer concrete beams is compared by conducting bending tests to determine the shear behavior of new generation geopolymer concrete produced from entirely construction and demolition wastes (CDW). In these tests, geopolymer concrete with recycled aggregates, geopolymer concrete with natural aggregates, conventional concrete with recycled aggregates, and conventional concrete with natural aggregates are used in order to study the possibility of reaching fully-recycled construction materials. Three different shear-span-to-depth ratios (a/d) are utilized to investigate the different modes of failure. Therefore, the structural performance of beams was, firstly, compared for mixtures without recycled aggregates to control the possible side effects of 100% recycled concrete construction. Load-deflection curves, moment-curvature curves, and crack patterns were utilized to conclude the performance of geopolymer concrete. Test results revealed that geopolymer concrete beams exhibited similar performance to the conventional concrete beams of the same grade. However, the inclusion of recycled aggregates caused a shift in the failure mechanism from shear-dominated to flexure-dominated, especially in specimens with larger a/d ratios. Finally, the capacity prediction performance of current codes, i.e., TS500 and ACI318, are also examined, and the calculations resulted that the current code equations have a percentage error of approximately 55% on average, although TS500 equations performed slightly better. / The authors gratefully acknowledge the financial assistance of the Scientific and Technical Research Council (TUBITAK) of Turkey and the British Council provided under projects: 218M102 and European Union’s Horizon 2020 research and innovation programme under grant agreement No: 869336, ICEBERG (Innovative Circular Economy Based solutions demonstrating the Efficient recovery of valuable material Resources from the Generation of representative End-of-Life building material).

Recognized as one of the main obstacles to sustainable development, climate change is caused and accelerated by the greenhouse gas (GHG) emissions generated from all energy end-user sectors. The building sector alone consumes around 40% of all produced energy worldwide. Reducing this sector’s energy consumption has therefore come into focus as one of the key issues to address in order to meet the climate change challenge.Implementing sustainable construction practices, such as LEED, can significantly reduce the building’s energy and water consumption. Prescribing these practices may however encounter several barriers that can produce other than intended results. Since the beginning of 2008 Dubai mandates a LEED certification for the better part of all new constructions developed within the emirate, nevertheless the success of this regulation is debatable.This thesis identifies the barriers the introduction of the sustainable construction practices in Dubai faced and analyses the reasons why the regulatory and voluntary policy instruments were not effective in dealing with these barriers. Understanding these barriers as well as the merits and weaknesses of the policy instruments will help future attempts to introduce sustainable construction practices.To put the research into context a literature review of relevant printed and internet sources has been performed. In order to further understand the barriers the construction market in Dubai faced, qualitative observational research methods have been used. In addition the input of different key stakeholders with unique knowledge of the construction market was deemed to be necessary. Finally, for purposes of verification, the research relied on quantitative methods using different databases that provide detailed information about construction projects in the United Arab Emirates.The thesis concludes that several barriers, such as a) financial, b) market related, c) behavioral and organizational, d) political and structural, d) technical and e) information barriers hindered the introduction of sustainable construction practices in Dubai. Furthermore the introduced policy mechanisms were not effective in providing clarity on the scope of the policies and environmental goals, failed to provide financial incentives to investors or developers and considered only weak enforcement mechanisms.As a final outcome the thesis presents a number of suggestions that should increase the number of LEED certified projects. These suggestions include changes in the current regulations, the introduction of new policy mechanism such as a building code and major changes to the energy policy such as the correction of the utility prices and the liberalization of the energy market.
