Como trabalho futuro sugere-se:
1. Analisar o impacto que a ativação do modo de funcionamento eficiente das UTA teria nas economias globais do sistema de climatização. É sabido que o funcionamento destes equipamentos influencia diretamente o consumo dos
chillers e caldeiras, pelo que se considera que estes equipamentos possuem um
grande potencial de poupança energética;
2. Realizar um comissionamento extensivo dos vários sistemas para tentar identificar problemas nos equipamentos (através dos registos de monitorização funcional), dado que o sistema apresenta alguns problemas a este nível;
3. Realizar um trabalho de conceptualização e implementação de alarmística avançada que permita a deteção automática de problemas do funcionamento do sistema, com recurso aos registos funcionais.
