Os sistemas energéticos para habitação autossustentável em clima português: simulação e análise energética
| Resumo: | In 2010, the European Union launched the Directive 2010/31/EU on the Energy Performance of Buildings, with the objective of improving the energy performance of buildings taking into account local bioclimatic conditions. This policy also aims to inforce the requirent of all new buildings to be infrastructure with nearly zero- energy NZEB (Nearly Zero Energy Building), as from December 2020 . This study portraits a typical single-family housing in the context NZEB (Net Zero Energy Building) through a photovoltaic system in Portuguese climate. Taking into consideration the great climatic diversity throughout the Portuguese territory, four geographical areas were selected with different characteristics to target this study - the areas selected were: Bragança, Coimbra, Lisbon and Faro. Using the EnergyPlus program, dynamic simulations were made of the parameters that influence energy efficiency in a building, being its geometry and orientation; the type of cooling system; and finally, its lighting efficiency and appliance efficiency. There were analyzed all of the variations of these parameters in order to identify the best configuration possible of constituents in the building systems, taking simultaneously an energy and environmental perspective. With the purpose to study the influence of geometry on the thermal behavior of a building, two models with distinct geometries were analyzed: a model called "Passive House" - which represents a housing provided with "passive solar construction", with low needs of heating and cooling; and a second model, called "House Glazed" - that represents a house with large glass areas, which tend to have higher energy requirements in the cooling season. Through the Solterm program, photovoltaic and solar thermal solar systems were sized so as to meet the annual energy needs for each model. It was also analyzed the economic impacts of solar photovoltaic system to verify its viability in each building. |
