A Novel Cost-efficient Daylight-based Lighting System For Public Buildings: Design And Implementation

Abstract

In this study, design and implementation of a new cost-efficient daylight-based lighting control system is proposed to provide energy saving in a public building with a conventional lighting system. Energy gain recovery and regional daylight utilization coefficients are obtained by conducting daylight measurements in all indoor spaces of the building where the proposed lighting system will be applied. Daylight value is continuously transferred to the control system through the pyranometer placed outside and the need for artificial lighting is calculated by using sectional daylight utilization coefficients. Thereby, maximum benefit from daylight is realized when unnecessary energy consumption for artificial lighting is reduced. Experimental measurement results show that the proposed daylight-based lighting control system provides an average energy efficiency of the building at the level of 60 %. Additionally, the required investment, such as operating cost and payback period for converting an existing conventional lighting system into the proposed system, are discussed in detail. Cost analysis shows that the payback period of the proposed system can be reduced by 5 years compared to the conventional system.

Design of Indoor Lighting Control System for Human Body Signal Acquisition Based on Internet of Things

“…Tan et al proposed a sensor-driven human, on top of it lighting framework [1]. Ayaz et al proposed the plan and execution of another savvy sunshine-based lighting control framework to furnish energy reserve funds in open structures with ordinary lighting frameworks [2]. Karapetyan et al studied that the Internet of ings (IoT) brings a new paradigm of integrated sensing and actuation systems for intelligent monitoring and control of smart homes and buildings [3].…”

“…It mainly introduces incremental kernel fuzzy clustering algorithm and support vector machine algorithm. (2) In the face of indoor lighting control, after each command is sent 100 times, the number of successful times is recorded and analyzed.…”

Design and Analysis of High-Efficient Driver Model for LED Luminaires

“…LEDs, which are preferred because of their features such as making efficient lighting with less energy consumption, become more widespread for the illumination applications [3][4][5][6][7][8]. LED illumination is not only used in the night but also applied and used in offices, schools, industrial installations which are active during daylight [9]. In general, PV supplied lighting systems are preferred for illumination in such buildings.…”
