ABSTRACT: The waste Polyethylene Terephthalate (PET) particles combined with pozzolanic materials can be used in the production of concretes with the goal of diminish the quantity of waste in landfills and reduce the depletion of natural resources. However, little has been researched about the environmental viability of the use of wastes in the production of concrete, and no assessment […]
Technologies for a sustainable built environment
Innovative skins and domotic systems: the technological design for residential buildings’ energetic efficiency
ABSTRACT: Comfort and efficiency needs require the realisation of “smart architectures” with a supervised energetic and environmental operations, consisting of dynamic skins: complex systems made up of blocks and filters able to adjust heat, solar radiation, air and vapour flows and also to convert the radiations in energy (heat energy and electricity). The innovation works above all through the […]
Characterization and Thermal Performance of a Compressed Earth Construction System for Improving Comfort and Achieving Energy Savings
ABSTRACT: Earth has been used historically as a construction material in various regions and cultures for thousands of years. The primitive earth structures consisted mainly of simple wooden frames covered with mud. Earth constructions are usually built in locations where other construction materials are relatively scarce. The process of its fabrications consists of sun-dried mud or adobe bricks with […]
Industrial waste: Study for adding or partial replacement in Portland cement
ABSTRACT: In an attempt to mitigate the environmental impact of industrial activities and the assumption of scarcity of raw materials due to the impacts experienced in the present world seek out alternatives for recycling of industrial waste generated on macro complex civil construction sector. The objective of this study was to promote a literature review of promising approaches published […]
Double Glazings: Spectrophotometric Characterization for Facade Modules
ABSTRACT: Glazing contributes significantly to heat transfer between outdoor and indoor spaces and these surfaces act directly on daylighting and thermal comfort. Based on these aspects, spectrophotometric characterization of double glazings was accomplished to study components for a modular facade system for the climate of Portugal. This study focused on results of spectrophotometric measurements of optical behavior in the different […]
Green Roofs: Manual structure proposed for Brazilian cities
ABSTRACT: Regarding green roofs, policies and encouragement strategies have been adopted for more than thirty years in countries such as Germany, Switzerland, Japan and Canada, where there are supportive standards, guidelines and manuals. In Brazil, this issue is recent and several laws are being proposed in recent years, but they are superficial and do not show strong technical or […]
Balcões refletores e a disponibilidade da iluminação natural em salas de aula: O caso do Instituto Federal do Espírito Santo – Campus Colatina
RESUMO: O presente estudo trata da iluminação natural no ambiente interno, com foco específico nos ambientes escolares. O objetivo é demonstrar a influência de balcões refletores, associados à elementos bloqueadores da luz solar direta, na disponibilidade da iluminação natural em salas de aula. O objeto de estudo são as jardineiras existentes próximas às janelas da sala de aula […]
Wood Frame Housing System: Case Study and Application Potential for Low-Cost Housing in Foz do Iguaçu
ABSTRACT: The lack of housing in Brazil is around 5,430 million. Nowadays, this problem is one of the biggest challenges of the country. This situation must encourage the research of technological solutions for the production of satisfactory performance houses. Wood Frame housing system could be an option. It is used in North America, Asia and Europe and now is […]
Windows and Facades: Proposal of a Device for Increasing Performance for Natural Ventilation and Daylighting
ABSTRACT: Buildings energy consumption in Brazil corresponds to about 47% of total consumption. In this respect, facades and windows are elements which influence directly that consumption. Thus, the aim of this work is the study of a device for windows and facades, which operates to increase building energy efficiency, without adding monthly maintenance costs. The proposed Sun-Air-Light device has […]
The contribution of green roofs to mitigate urban heat island effect in Rio de Janeiro
ABSTRACT: Green roofs represent the reintroduction and inclusion of vegetation and biodiversity in the built urban environment. The integration of vegetation through green roofs; for example, using grasses, succulents, flowers, shrubs, and trees in urban areas is particularly important to maintain cool built urban environment because buildings, streets and other infrastructures increase the heat absorption, which results in the […]
