Comparação de ferramentas de simulação térmica para o cálculo dos índices subjacentes à certificação nos edifícios de comércio e serviços
| Resumo: | Since December of 2013, selling or renting a real estate is only possible if it has an Energy Performance Certificate. This sudden imposition, forced the real estate agencies and private owners to make a significant effort to obtain these certificates, which induced in an increase in the demand for the services provided by the Experts of this technical field. The certification of Small Buildings of Services and/or Commerce, known as PES in Portuguese, is more complex than housing, ergo, it was necessary to search for modelling tools that could make the certification process simpler, while still presenting reliable results in the case of multizone buildings. This master thesis compares two models for the energy categorization of a services building: The STE-Monozona and the HAP, to find out if is possible to use the simplified method of dynamic modelling to certificate a multizone building. The study begins with a bibliographic review of the energetic regulations, the certifications process and the modelling methods used in this dissertation. The next topic is about the study-case characterization and the simulation process, finishing this document with the analysis of the results from the simulations. The results obtained and showed in this report suggest that it is possible to determine the energetic class of a PES using the STE-Monozona (simplified dynamic method). However, due to the simplicity of the calculous methodology, this method should not be used to identify improvement measures because the heating and cooling loads calculated through this method are not the real values. |
