为提高能效而更换照明设备是实现更高企业能效和可持续性目标的几个重点之一。在沙特阿拉伯人为压低的能源价格下，再加上现有的浪费能源文化，实现这些目标变得更具挑战性。为了在这些具有挑战性的条件下实现能效目标，必须确定公司在进行照明更换时应遵循的系统方法，以避免意外陷阱。本文介绍了一种定义照明更换策略的系统方法，该策略包括以下内容:照明类型、位置、功效、成本和服务分类。 本文还介绍了一个实际的生命周期成本实例，作为评估更换成本效益的决策支持工具。研究结果强调了照明更换在满足目标能耗和减少CO²排放方面可以发挥的重要作用。本文提出的方法可供在类似环境下运营的组织采用，以展示其在能源效率和环境合规性方面的领先地位。引用:2016年冬季会议，佛罗里达州奥兰多，会议论文

Replacement of lighting equipment for improved energy efficiency is one of several keystones for meeting higher corporate energy efficiency and sustainability targets. Meeting these targets under the artificially low energy prices of Saudi Arabia, coupled with an existing culture of wasteful energy usage, becomes more challenging. To meet energy efficiency targets under these challenging conditions it is essential to identify a systematic approach that companies should follow when performing lighting replacement to avoid unexpected pitfalls. This paper introduces a systematic approach to define a lighting replacement strategy that comprises the following: lighting type, location, efficacy, cost and service classification. The paper also presents an actual life-cycle cost example as a decision support tool to evaluate replacement cost effectiveness. Study results highlight the significant role lighting replacement can play to meet target energy consumption and reductions in CO2emissions. The approach proposed in this paper can be adopted by organizations operating under similar environments that want to showcase their leadership in energy efficiency and environmental compliance.
