Item Avaliação ambiental de sistemas de aproveitamento de água pluvial em habitações de interesse social(Universidade Federal de Goiás, 2017-08-24) Brandão, Verônica Ribeiro; Campos, Marcus André Siqueira; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4775503A; Brandstetter, Maria Carolina Gomes de Oliveira; Barreto, Douglas; Campos, Marcus André SiqueiraDespite the constant technological advancement of humanity and the increased efficiency of production inputs, we can still face with situations of extreme poverty and need throughout the world. In Brazil the reality is not different, where we can identify a housing deficit of more than 5 million residences since 2007. In this way, public policies were created that aim to reduce this index. The present work seeks in this context, environmental solutions that can mitigate the impacts generated by these enterprises. Therefore, we suggest the application of Rainwater Harvesting Systems (RWH) in social housing (SH) and the simplified Life Cycle Analysis (LCA) as a tool to be used in these issues. For the bibliographic review, was applied the methodology of Systematic Literature Review (SLR) as an instrument for the efficient search of bibliography. Through this search it was possible to verify the breadth of research that applied the LCA in RWH. The methodology proposed by Tavares (2006) and applied by Marinoski (2010) were adopted for the comparison between two scenarios of rainwater harvesting, an individual and a collective. In addition, two sets of inventory data were presented in this study. The first one comes from national data and the second from international data. The results were presented as 19 environmental indicators based on embedded energy (EE) and embedded carbon dioxide (EC) in the materials used in RWH and in the operation of the system. The indicators were used to make comparisons between the systems and it was verified that the collective scenarios are more environmentally friendly than the individual ones. This occurred because the operating EE and EC of the individual systems, presented values on average 4 times higher than those presented by the collective systems.Item Impacto das variáveis de projeto nas características físicas do escoamento de esgoto em tubulações prediais(Universidade Federal de Goiás, 2019-08-29) Bucar Filho, Cláudio Lustosa; Vasco, Joel Roberto Guimarães; http://lattes.cnpq.br/2787228916381075; Campos, Marcus André Siqueira; http://lattes.cnpq.br/3212762899289587; Campos, Marcus André Siqueira; Brandstetter, Maria Carolina Gomes de Oliveira; Reis, Ricardo Prado AbreuThe study of the fluid behavior in the sewage system of building systems is highly complex and difficult to predict. This is due to the characteristics of the problem, such as free surface runoff, high randomness in system flow rates and inhomogeneity characteristics of the liquid containing faeces, paper, food remnants, soap and others. Even though it is one of the major responsible for the large amount of post-work technical assistance in Brazil, this topic is not much studied. Therefore, this paper analyzes the influence of design variables on runoff behavior within sewage systems. For this purpose, experimental tests were performed in a residential building, and the analysis parameters were: the height at which the discharge is performed, the flow / volume of the discharges, the types of connections used in the plumb diversion and the sub-collector configurations. Thus, with the results of this research, it is possible to help in the understanding of decision making contributing to a better performance of buildings. As a result it can be observed that the higher the discharge height, the lower the transport speed of the media and the lower the height of the water slide within the network, thus the greater the chance of solids retention within it. In relation to the discharge flow, the higher the flow values the higher the transport speeds of the media. Connections installed on the network, both in the plumb diversion and the sub-manifold, have a considerable influence on media transport speeds and should be chosen to have the least possible impact. This study concludes that more research is needed to help renew the NBR 8160 standard with support for changes in sizing conditions and installation / execution options.
