RESUMO: A partir de 31 de dezembro de 2020, pretende-se que todos os edifícios novos na União Europeia sejam nZEB, edifícios com necessidades energéticas quase nulas. No edifício Solar XXI, em Lisboa, encontra-se uma sala laboratorial sob monitorização equipada com sistemas de controlo de temperatura. O objetivo deste estudo é validar uma simulação da sala em EnergyPlus com os dados obtidos experimentalmente e determinar o impacto dos sistemas nas necessidades energéticas e conforto térmico dos ocupantes. Dois sistemas em particular foram analisados: o sistema BIPV, para o inverno, e o sistema dos tubos enterrados, para o verão. Após validação, uma simulação da sala sem os sistemas foi efetuada, de modo a determinar o impacto de cada um. Resultados mostram que, para os períodos analisados, o BIPV reduziu as necessidades de aquecimento em 20%, além de aumentar o conforto térmico do ocupante, e os tubos enterrados reduziriam em 93% as necessidades energéticas de arrefecimento. A análise efetuada contribui para a promoção dos KETs no setor dos edifícios.
ABSTRACT: After 31 December 2020, it is intended that all new buildings in the European Union are nZEB, nearly Zero Energy Buildings. In the Solar XXI building, in Lisbon, there is a monitored test room equipped with temperature control systems. The objective of this paper is to validate a simulation of the room in EnergyPlus with the data obtained experimentally and determine the impact of the control systems on energy needs and on occupant thermal comfort. Two systems in particular were studied: the BIPV system, during the winter, and the earth tubes, during the summer. Once validated, the simulation of the room without the systems were made, allowing their impact to be determined. Results show that, for the analyzed periods, the BIPV system reduced the heating needs by 20%, while also increasing the occupant’s thermal comfort, and the earth tube system would reduce the cooling needs by 93%. The analysis performed enables the promotion of KETs in the building sector.
