Innovative control logics for a rational utilization of electric loads and air-conditioning systems in a residential building

The paper focuses on the evaluation of the impact on residential buildings of innovative control logicsdefined for a rational utilization of the electric loads and air-conditioning systems. The control logics areimplementable thanks to a Decision Support and Energy Management Systems developed by the sameauthors and easily installable in new and still-existing houses.The paper shows how a significant reduction of the primary energy consumption can be obtained bycontrolling the air-conditioning units together with the other electric loads of the house.After having explained how the control logics operate, a simulation tool is described, developed for apreliminary evaluation of their effects on the energy consumptions of residential buildings in the designstage. An application of the simulation tool on a typical house, considering different scenarios and varyingthe climatic conditions and the energy performance class of the envelope, is presented.Finally, a measurement campaign on two real existing houses, equipped with the Decision Support andEnergy Management System, is described, and the effects of the control logics are assessed
