Inserção de simulações de desempenho térmico no processo de projeto

The increasing energy consumption in buildings is a matter of concern. How buildings behave concerning the weather is important regarding their final consumption since initial design guidelines can reduce future consumption projection. These guidelines seek to optimize the thermal performance of the building by reducing cooling needs and, at the same time, keeping indoor temperatures passively. However, thermal performance analyses are performed in late design, making it difficult to achieve good performance levels without much room for project change. Aiming to unite the process to these analyses, the objective of this work is to collect data about the architects' design process and create a framework. Also, to understand which performance parameters are already considered in the design process, which others could be and which design phases in which the project definition parameters have greater relevance from a thermal performance perspective. Despite considering the evaluation of criteria such as natural lighting and ventilation to be relevant in the design, the participants in this study do so with inaccurate methods. Besides, there was a lack of knowledge of important aspects, such as NBR 15575, the energy efficiency label, and computer simulations. From these results, a framework is proposed to facilitate the integration between the two studies, in which thermal performance simulations are embedded in the design process. Furthermore, the framework allows future experiments, including thermal performance simulations, to validate its design process.
