- Analysis of heat balance in a light steel frame residence with different insulating thicknessPublication . Consoli, Isabel Oberderfer; Andrade, Carlos A.R.; Tabalipa, Ney LyzandroSustainability and efficiency in buildings are concepts that have been recently growing and developing. Its application in several buildings has become mandatory in many countries around the world. One of the major challenges faced by sustainable buildings is the achievement of satisfactory levels in efficiency terms, without negatively impacting the economics. The residential construction sector has great potential for energy savings and is also where building strategies need to be carefully planned, as they seek to meet the needs of residents not only in the present, but also over time. Residential design must be done thoroughly and must include the analysis of all climate variables involved. In order to verify a residential building envelope behaviour regarding energy and thermal efficiency, this paper intended to evaluate through software Design Builder®, walls and roofs with a rock wool layer, placed in a Light Steel Frame (LSF) house.

- Future land-use and and-cover scenarios for mapping flood-prone areas in Pato Branco city, BrazilPublication . Dalanhol, Isabel; Tabalipa, Ney Lyzandro; Silva, FloraUrban flooding is the most common type of disaster and the one that hit people most. Unplanned urbanization processes increase the recurrence of these events due to soil impermeabilization. Thus, land-use and land-cover is an important factor for urban flood research. Besides, mapping flood-prone areas has been an alternative for disaster prevention and urban planning. However, the use of future land-use and land-cover scenarios for flood mapping is a factor that still requires investigation. The study that is being developed by the authors of this paper aims to identify flood-prone areas in the upper third of the Ligeiro River basin in the city of Pato Branco, Parana, Brazil. For this purpose, this research makes use of the GIS-AHP integration, considering a current scenario and future land-use and land-cover scenarios. Therefore, the objective of the present study is to construct possible land-use and land-cover scenarios, according to municipal legislation, that could serve as a basis for mapping flood-prone areas. Two scenarios were built using Geographic Information Systems software. This tool proved to be efficient in the elaboration of maps and land representation. Pato Branco already has a history of flooding with the current scenario of land-use and land-cover. With future land-use and land-cover scenarios, it is possible to verify the influence of urban sprawl on urban flooding.

- Identificação de áreas suscetíveis a inundações em Pato Branco, BrasilPublication . Dalanhol, Isabel; Silva, Flora; Tabalipa, Ney LyzandroAs inundações urbanas são influenciadas pelos processos de urbanização e resultam em efeitos ambientais, sociais e econômicos importantes. Desta forma, as alterações no uso e ocupação do solo podem trazer impactos positivos ou negativos na ocorrência destes eventos. A utilização de mapas tem sido uma forma de avaliar as expansões urbanas ao longo do tempo e suas influências nas inundações urbanas. No entanto, ainda é necessário explorar a interferência de cenários futuros de uso e ocupação do solo nas inundações urbanas. Esta dinâmica pode servir como amparo para quaisquer ampliações e alterações do perímetro urbano. Neste sentido, esta pesquisa tem como objetivo identificar as áreas suscetíveis a inundações no terço superior da Bacia do Rio Ligeiro, na cidade de Pato Branco, Brasil. Para este fim, o estudo utiliza a integração dos Sistemas de Informação Geográfica (SIG) e do Analytic Hierarchy Process (AHP) ao considerar um cenário atual e cenários futuros de uso e ocupação do solo. O software SIG utilizado se mostrou eficiente no mapeamento dos cenários futuros de uso e ocupação do solo. Para além disso, os resultados parciais da pesquisa apontam essencialmente para a parte norte da área de estudo como região passível da ocorrência de inundações urbanas. Após a aplicação do AHP, com critérios atribuídos por especialistas, espera-se que seja possível confirmar as zonas de risco de inundação no perímetro urbano, além de verificar a influência do potencial de urbanização sobre estes eventos e auxiliar no planejamento urbano do município.

- Remoção de matéria orgânica e nutrientes de efluentes líquidos em diferentes condições hidráulicasPublication . Silva, Flora; Albuquerque, António; Cavaleiro, Victor; Carvalho, António; Scalize, Paulo; Tabalipa, Ney Lyzandro; Monte, Helena Marecos doA recarga artificial de aquíferos com águas residuais tratadas pode contribuir para a reposição de volumes de água no solo. Um solo residual da região da Beira Interior de Portugal, foi caracterizado e utilizado para avaliar a sua capacidade para remover poluentes residuais de efluentes de tratamento secundário. Utilizaram-se experiências em coluna laboratorial usando diferentes condições hidráulicas, tendo os resultados mostrado uma maior remoção de matéria orgânica nos ensaios com alimentação descontínua. A remoção de amónio, nitrato e fosfato ocorreram a valores elevados quer nos ensaios em contínuo quer nos ensaios em descontínuo. O solo utilizado é adequado para a remoção de cargas residuais de matéria orgânica e nutrientes, podendo ser utilizado para a infiltração de águas residuais tratadas.
- Thermal balance analysis in a light steel frame residence with different insulation material thicknessPublication . Consoli, Isabel Oberderfer; Tabalipa, Ney Lyzandro; Andrade, Carlos A.R.Sustainability and efficiency are concepts that have been spreading in civil construction. Among all building types, residential buildings have great potential for energy savings. It is where building strategies need to be carefully planned, as they seek to meet the needs of residents, and also provide security and comfort. Well-designed houses will also provide resource saving over time, as they add climate analysis, design strategy studies and appropriate materials to their design. In order to verify a Light Steel Frame house behavior regarding energy consumption for heating and cooling, this paper aims to evaluate walls and roofs with layer different thickness of rock wool and expanded polystyrene as insulation materials. The applied methodology to obtain energy efficiency will be through analysis in the software Design Builder®. The constructions in Portugal are mainly made of masonry and the search for alternative construction solutions aimed at complying with Directive (EU) 2018/844 is relevant. A drastic change in collective thinking will be necessary. This article aims to show as result the energy efficiency of Light Steel Framing construction solutions, presenting the materials which have the greatest benefits regarding energy consumption.
