Esta dissertação apresenta um sistema que permite desenvolver e avaliar
remotamente metodologias que utilizam a flexibilidade energética disponibilizada por
dispositivos controláveis presentes em edifícios de escritórios. Tendo em conta a
importância do conforto dos ocupantes no estudo da flexibilidade energética, o sistema
foi desenvolvido considerando um contexto Living Lab, onde os ocupantes dos edifícios
têm uma participação ativa na caracterização e utilização da referida flexibilidade. Para
ilustrar o funcionamento do sistema desenvolvido considerou-se um caso de estudo onde
a flexibilidade energética é fornecida por uma bomba de calor, sendo o seu funcionamento
controlado com o objetivo de reduzir os custos associados ao consumo de energia elétrica
do escritório em questão. Os resultados obtidos mostram que a utilização da flexibilidade
energética pode conduzir a poupanças, que resultam de um menor consumo energético
nos períodos associados a tarifas mais elevadas, enquanto os níveis de conforto térmico
dos ocupantes são respeitados.
This dissertation presents a system that allows the remote development and evaluation of methodologies that use the energy flexibility provided by controllable devices present in office buildings. Considering the importance of occupant comfort in the study of energy flexibility, the system was developed considering a Living Lab context, where building occupants have an active participation in the characterization and use of such flexibility. To illustrate the operation of the developed system, it was considered a case study where the energy flexibility is provided by a heat pump, being its operation controlled with the objective of reducing the costs associated with the office electricity consumption. The results show that the use of energy flexibility can lead to savings resulting from lower energy consumption during periods associated with higher tariffs, while occupant thermal comfort levels are respected.
