Abstract

The street lighting is one of major components in total energy consumption in cities. The paper is focused on a concept of street lamp control systems and function organization with remote monitoring, to reduce maintenance costs and energy consumption. A new approach to the definition of functional strategy organization for outdoor lighting systems is introduced in the paper. Proposed functional strategies are based on four efficiency classes of building automation and control systems (BACS) defined in the EN 15323 standard. They have been formulated, analysed and eventually implemented and verified in real experiment street lighting installation. This outdoor lighting system, designed by the authors, based on LonWorks (the ISO/IEC EN 14908) platform with a power line communication aimed to control high-pressure sodium lamps. The street lamps are integrated nodes of a building management system (BMS). The results of experimental tests for the proposed functional strategies, implemented with various control scenarios, show that they provide a great potential in reducing energy consumption by street lighting installations. In particular, the energy use can be reduced even by 45 % in comparison to conventional street lighting system, especially without the use of monitoring and control.

Highlights

The street and outdoor lighting installations provide citizens with safe roads, stylish and inviting public areas and enhance the security in their homes, businesses and city centres
The proposed functional strategy corresponded to the class B assumptions (Figs. 7, 9, and 11) causes the street lighting system to have a much lower energy consumption compared to installations made with standard lamps (Fig. 6), which do not have functions of scheduling and regulating the light intensity level
In this paper new approach to infrastructure and control systems organization in the street and outdoor lighting installations is introduced. It is based on the EN-15,232 standard guidelines originally dedicated to organizing control functions and functional strategies in the building automation and control systems (BACS), but we propose a new concept to extending the application area of this standard in the street lighting installations

Summary

Introduction

The street and outdoor lighting installations provide citizens with safe roads, stylish and inviting public areas and enhance the security in their homes, businesses and city centres. Our concept, presented in this paper, is universal and could be used to evaluate the organization, functional strategies of the street lighting control systems and their impact on the energy consumption for installations with all kinds of lamps (HPS, LEDs etc.).
