12、ifferentiate the lighting design suggestions presented here from those contained in other IES publications. While these other publications may refer to security, in this Guide, security is the primary issue.When security is an issue, not only lighting but also other measures and system components de

13、serve consideration and integration into the final design. Likewise, when security is an issue, there may be instances when other security measures are enhanced but lighting is not a primary consideration due to site location and usage. The primary purpose of this publication is to help users unders

14、tand when security is an issue and provide guidelines for the design and implementation of appropriate security lighting for the private and public sector.There is a distinction made in this document between security lighting and lighting for safety. Security lighting is intended to protect people,

15、property, and vital infrastructure from criminal and terroristic activities. Lighting for safety is intended to provide secure working conditions, secure passage, and identification of hazards or obstructions. This document addresses security illumination but does not give advice on technical constr

16、uction practices. The objective is to provide guidance for designing security lighting systems for new facilities and for evaluation and retrofitting of existing facilities and systems in response to known or perceived threats. This publication is for the use of property owners and managers, crime p

17、revention specialists, law enforcement and security professionals, risk managers, lighting specifiers, contractors, homeowners, and those responsible for the protection of critical infrastructure who are concerned about security and the detection and prevention of crime and terrorism.2.2 What is Cri

18、me?The classical definition of crime10used in common law involves violations of established written criminal statutes published by a government. (For more information on crime, categories of crime, and foreseeability of crime, refer to Annex C.)In this Guide, crime, its prevention, and the applicati

19、on of lighting to help in the efforts to minimize criminal activity are considered in a less technical manner components), night movement of people increased rapidly in public spaces.Experimentation and wide use of night security and safety lighting has since expanded throughout most of the world wh

20、ere sources of electrical energy are readily available. The search for improved and cost effective delivery methods continues. These newer delivery methods will be discussed later.The US Military and national security agencies throughout the world have long recognized the critical importance of secu

21、rity lighting to aid in the protection of their citizens, critical installations, and infrastructure.60During both World Wars, security and light discipline applications expanded rapidly. Since the terrorist attacks on September 11, 2001, the number and type of facilities considered critical and rec

22、eiving upgrades in security lighting have expanded to include such heretofore-ignored elements as bridges, tunnels, communications hubs, transportation transfer points, and international borders. The IES continues to play an important role in our knowledge and application of security lighting.Althou

23、gh there are many research studies showing inconsistent results on the benefits of improved nighttime lighting, one seminal study was conducted in Stoke-on-Trent, England, in 1999.61Three areas of housing were selected: the experimental area, where the lighting was improved; the designated “adjacent

24、” area; and the control area, which served as the baseline against which any changes in crime could be monitored. The lighting in the adjacent and control areas remained unchanged. One aspect of the study was to see whether improved lighting in one area might lead to similar benefits of crime reduct

25、ion in the adjacent area. There was a marked reduction in the prevalence of crimes, including theft and vandalism, vehicle crime, and personal crime, in the experimental area after relighting. There was no significant change in the adjacent or control areas. A similar study in the town of Dudley, En

26、gland,62 showed that the level of delinquency decreased more in the relighted area than in the control area.This publication includes specific sections dealing with critical infrastructure19and homeland security.20In addition, we have incorporated many of the lessons learned and applied by these age

27、ncies throughout.2.0 SCOPE AND PURPOSEThis document is intended to provide specific guidelines for situations where it has been 4IES G-1-16 Complement or enable other security devices Through fear of detection, deter persons from committing crimes or terroristic acts Aid in the apprehension of crimi

For example, 1.5 meters and its USCS equivalent of 5 feet are displayed as 1.5 m (5.0 ft), while 108 lux and its footcandle equivalent are displayed as 108 lx (10 fc). These and other conversions are rounded to the nearest one-tenth and are approximate, but are co

30、nsidered sufficiently accurate in this context. For more detailed and accurate definitions, refer to ANSI/ IES RP-16-10, Nomenclature and Definitions for Illuminating Engineering, and The Lighting Handbook, 10thed. (IES 2011). (Note: The Lighting Handbook, 10thed., states that a lux-footcandle conve

31、rsion of 10 lux to 1 footcandle is acceptable unless specifically noted otherwise. In this Guide, the conversion used is 10.76 lux = 1 footcandle.)3.0 UNDERSTANDING “WHEN SECURITY IS AN ISSUE”In considering whether to implement the recommendations in this Guide, it is important to recognize that sec

32、urity is not always a particular concern for the lighting design. Not all properties, centers of activity, or gathering places require special consideration or enhanced security. It is not acceptable to merely say or accept without reason that . . . security is always an issue. Rather, it is critica

33、l for those responsible for risk management and crime prevention to perform due diligence11to determine what the actual risk is and plan countermeasures accordingly. Clarification and tools for performing due diligence are provided throughout this document. Law enforcement, security staff, designers

34、, management professionals, and facility owners should consider security an issue when one or more of the following conditions exist or can be expected to exist: The persons and/or property being secured present a desirable target to would-be criminals or terrorists.to increase the documents accessi

35、bility. Lighting designers, architects and other professionals may also wish to consult more-technical design publications as to how these guidelines can best be implemented. Each site will of course present its own challenges, and the IES offers a wide range of technical support tools to assist in

36、these inquiries.This publication contains material useful in determining when crime is an issue for a facility and therefore in need of specific security lighting consideration. It also provides discussion of basic security principles; crime prevention concepts; light level criteria for a variety of

37、 applications; a protocol for evaluating current lighting levels; a security survey and crime search methodology; and other recommendations. Suggestions are given for exterior and interior security lighting practices for the reasonable protection of persons and property. This document encourages the

38、 concept of best security practice, which also takes into account the following design issues for lighting: Economics, including installation, maintenance, and lifecycle costs Energy conservation and minimizing maintenance requirements Environmental issues such as light pollution, light trespass, an

39、d the adverse effects of light on animals and plants Local community needs, practices, and standards Protection of national critical infrastructure and key resourcesMinimum guidelines for the secure movement of persons and equipment and for performing specific tasks can be found in other IES publica

40、tions.Security lighting, as part of a well-balanced security plan, should have the following objectives: Facilitate the visual ability of those performing security or enforcement functions Provide a clear view of an area from a distance, and enable anyone moving in or immediately around it to be eas

41、ily seen and recognized Remove potential hiding places Permit facial identification at a distance of at least 9.1 m (30 ft), and create the perception that those in the area are identifiable5IES G-1-16 Are there adequate post orders job descriptions for those tasked with carrying out security respon

42、sibilities and duties? Are policies and procedures for protection of assets up to date, and do these documents address relevant issues? Have tenants or those who occupy or use the space been advised of the potential threat level or hazard? Have tenants or those who occupy or use the space been advis

43、ed of methods of deterrence and proper actions to take in the event of an incident? Have public and private law enforcement agencies been notified of the condition, and did this notification include a request for assistance or additional services? Has a security assessment, survey, or Crime Preventi

44、on Through Environmental Design (CPTED)12review been performed or updated since it was determined that security is an issue? Do changes in procedures, staffing levels, and/or security elements need to be addressed? Do illumination systems, light levels, uniformity ratios, glare control, and maintena

45、nce schedules meet recommended practices, standards, and code requirements?If there is a history of violence against persons on a property, then it is likely that crime of a similar nature will occur in the future, given the same circumstances. If a property has a history of incidents such as car th

46、efts, gang graffiti, abandoned cars, vandalism, damaged fences, or broken light fixtures or windows, a reasonable person could conclude that the site is not secure, and those responsible need to take action. Likewise, ongoing complaints from users of the property, changing conditions, or the introdu

47、ction of a high-risk business into the area, may either indicate or elevate the risk of crime and could pose a threat to both property and persons. Of particular concern are high-risk businesses where the controller of the property has determined through research, prior events, or the nature of the

48、business that users of the space are at increased risk after hours. The security professional and/or lighting designer should take note of this and plan accordingly. (See Section 4.7 Risk Management and Quality Assurance for more-detailed information.) There are especially vulnerable members of soci

49、ety on the property, such as high-profile leaders, the elderly, children, or the physically or mentally challenged. The property is a critical security or defense infrastructure, such as key government facilities, bridges, airports, checkpoints, and border installations, as determined by emergency planners. The property has a history of relevant crime or significant increases in relevant crime. Relevant crime in the surrounding area is high in comparison with other adjoining neighborhoods. Results of a physical security survey or threat analysis indicate a mean
