• Abstract

  It is widespread amongst professionals and researchers that buildings with higher external envelope thermal resistance are more comfortable and consume less energy. In a previous research, for Portugal and Southern European countries, it was verified that a highly insulated envelope can cause overheating in summer. The aim of this work is to do a similar study applied to Brazilian buildin…

  Influence of the external envelope u-value decrease on thermal and energy performace of buildings in Brazil, AP.R

• Abstract

  Building thermal performance simulation is generally used for a design's verification in final stages, when the highest gains in cost as well as thermal comfort are achieved in the early stages. Challenges for implementing these tools in such stages reduces the time, resources and expertise knowledge required. Simplified simulation tools are seen as an alternative; however, due to the ina…

  An assessment tool for social housing's thermal performance: considerations on natural ventilation, BP.MS

• Abstract

  Thermal comfort principles are essential to ensure good quality housing, but in most social housing projects in Brazil, such criteria have not been considered satisfactorily. Detailed computer simulation, that may preditc the performance of constructions in the design stage, are mainly used in the design's final stages to validate decisions already made. Since the high complexity of such…

  Assessment tool for thermal performance of social house: envelope considerations, BP.MS

• Abstract

  The main objective of the research is to evaluate the potential energy savings in office buildings with hybrid ventilation strategies through computer simulations of daylighting and thermal energy performance of these buildings in two distinct climatic regions in Brazil. The method consists in computer simulations of thermal performance and daylighting through the softwares EnergyPlus and…

• Abstract

  This project presents research to be conducted as part of an international internship scholarship; the proposed activities are related to parts of a master of science research entitled "Assessment tool for thermal performance of social house: envelope considerations" (FAPESP process n. 2013/16628-9) that will be performed at North Carolina State University (NCSU), Raleigh, NC. The propose…

  Development of regression models as an assessment tool for social housing's thermal performance in early design stages: consideration on building envelope, BE.EP.MS

• Abstract

  Building thermal performance simulation tools are important in a design process in all its stages, mainly in the early ones. However, some barriers prevent the effective implementation of these tools in architecture offices such as time, resources and the expertise knowledge required. Thus, regression models (meta-models), which are derived from a large number of robust simulations, are p…
