Energy saving in the street lighting control system—a new approach based on the EN-15232 standard

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.

A New Concept of Active Demand Side Management for Energy Efficient Prosumer Microgrids with Smart Building Technologies

“…The authors concluded that the BACS with TBM functions should be taken into consideration in future regulations and in national law on the energy performance of buildings. Similar suggestions with introduction of appropriate tools supporting buildings design process and taking into account the EN 15232 requirements are provided by the author of this paper in previous publications [27,56]. Moreover, in [79] the author presents a case study focusing on experimental verification of the impact of the BACS with TBM functions organized according to the EN 15232 guidelines on the energy performance of a typical university classroom.…”

“…The first two have been discussed in numerous research and studies. However, the third factor is not so obvious, but in recent years it has been taken into consideration especially by building automation engineers [27,56,[72][73][74][75][76][77]. As a result, the mentioned EN 15232 standard has been introduced in 2007 and revised in 2012 [28].…”

“…In the last decade, many of research and studies have been focused on developing of new functions and devices for the BEMS as well as various communication technologies have been considered to provide reliable connections and flexibility in the BACS field-level networks. In particular, in [19,25,53,[56][57][58][59], international, non-proprietary (open) standards dedicated for distributed building automation networks-EN 14908 (LonWorks) [60] and EN 13321 (KNX) [61]-have been proposed for the BEMS in microgrids and the SG. A New paradigm in BACS networks based on these standards is the implementation of the IoT technology with IPv6 protocol [26], providing a direct data exchange between network's nodes on the field-level, regardless of communication medium type (fieldbus or IP channels).…”

An Intelligent Luminance Control Method for Tunnel Lighting Based on Traffic Volume

“…Manual control, which is the earliest method employed in tunnel lighting, consists of turning lights on and off for different lighting circuits by the monitoring persons according to driving characteristics in an expressway tunnel during the day [19][20][21]. Sequential control divides the tunnel lighting operational modes into several categories according to the seasons and hours of the day [22]. Even though the two above methods are reliable and easy to implement in practice, the low degree of automation results in poor continuity and uniformity of luminance in tunnel interior [23].…”

Increasing the energy efficiency of warehouses using demand-side management mechanisms

“…In the presence of automation and building management mechanisms in accordance with EN 15232:2007 [23], the efficiency of the use of trigeneration [24] for different zones of warehouses is obvious. This leads to the emergence of the issue of demand-side management for electricity.…”
