One implementation of algorithms used to increase energy efficiency of premises

The development of systems used to increase the energy efficiency of premises has a broad ecological and commercial importance. The most significant savings are achieved by managing lighting. There are different types of systems used for lighting control: time switches, photocells, etc. The prototype of the lighting management system that has the possibility to use several algorithms for lighting control was developed and presented in this paper. The calculations of energy savings for each used algorithm and the comparison of energy consumption of different light bulbs have been done based on conducted measurements. The implemented system controlled by a microcontroller ATmega16 consists of a photoresistor, a zero crossing detector and a phototriac. Analyzed algorithms were written in the C programming language. From the conducted measurements and calculations it can be concluded that complex systems that combine several approaches in the scope of lighting management enable greater energy savings. Therefore, the implemented algorithm that has the ability to control the light intensity achieved the highest energy savings (38 percent).
