Thermal and lighting control system with energy saving and users comfort features

Building automation systems (BAS) provide automatic control of indoor environments conditions. Their primary goal is to realize significant energy savings, to reduce costs and to increase users comfort. In this paper improvements of the control system of a Building and Home Automation system previously presented by the author are presented. The system integrates energy-consuming sources for heat and light power supply, such as heat pumps and artificial lights with green energy-supplying sources like natural radiation and natural illuminance. In particular, in the present work, control solutions as a new thermal control policy, an anti-glare logic, and a logic for accounting of the solar radiation are introduced. This controller works satisfactory reducing the need for energy-consuming sources and it reaches good control performances and energy efficiency by making the best of the advantages of intelligence building.
