A presente dissertação descreve um conjunto de sistemas técnicos para climatização e produção de águas quentes sanitárias (AQS) destinados a edifícios de habitação. São ainda analisados os requisitos regulamentares definidos no Regulamento de Desempenho Energético dos Edifícios de Habitação (REH) relativamente à eficiência dos sistemas técnicos. O impacto dos sistemas técnicos no desempenho energético é avaliado através de um caso de estudo, que consiste numa moradia unifamiliar. Para essa moradia é selecionado um conjunto alargado de sistemas técnicos e o desempenho relativo dos vários sistemas é analisado à luz do REH. O estudo compara as diferentes soluções em termos das necessidades nominais anuais globais de energia primária, da classe energética, das emissões anuais de gases de efeito de estufa, do valor despendido na fatura energética anual e do custo estimado de aquisição e manutenção dos equipamentos.
The present dissertation describes a set of technical systems for climatization and domestic hot water (DHW) production for housing buildings. There is also an analysis of all the regulatory requirements defined in the Regulation of Energy Performance of Housing Buildings (REH), regarding the efficiency of technical systems. The impact of technical systems on energy performance is assessed through a case study, which consists of a single family dwelling. For this building, a wide set of technical systems is selected and their relative performance is analyzed according to REH. The study compares the differet solutions in terms of anual nominal primary energy needs, energy class, annual greenhouse gas emissions, amount spent on the annual energy bill and the estimated cost of equipment acquisition and maintenance.
