如今，新的照明技术正在迅速改变节能目标以及识别和获取节能的方式。由于居住者对室内舒适度和幸福感的期望正在改变照明设计和工程解决方案，因此有关在居住者、头顶照明和局部（任务）照明之间提供更多交互的系统的研究是谨慎的。本研究建立了一个价值主张，确定基于风险的节能潜力的交互式照明系统，同时评估方案的成功，通过测量居住者的心理社会变量。由头顶照明控制系统提供的改造后数据与来自各个可调台灯的经验能耗数据相结合，用于概率投资回报率（ROI）分析。描述性和相关性分析，员工的环境感知与能源消耗之间的联系。即使是在2011年进行了照明改造的适度节能办公楼，也有可能在9年内收回互动照明投资的成本。从概率上讲，回扣似乎是增加投资回报率的最重要因素。使用者认为安装台灯后，照明环境得到了整体改善，工作照明和头顶照明实现了“融合”。本文提出了一种可推广的混合方法来评估潜在的节省。交互式照明系统是未来建筑系统的代表，需要更多的人机交互，并且容易受到不规则的操作负载。这项研究可以帮助设施管理人员找到基于现有和新兴技术的实用解决方案，以利用现成的数据来帮助决策过程。
Today, new lighting technologies are rapidly changing energy savings goals and the ways in which those savings are identified and captured. As occupant expectations concerning indoor comfort and well-being are transforming lighting design and engineering solutions, research concerning systems that afford more interaction between occupants, overhead lighting, and local (task) lighting is prudent. This study builds a value proposition by determining risk-based energy savings potential of interactive lighting system while evaluating programmatic success through the measurement of occupants’ psychosocial variables. Post-retrofit data supplied by an overhead lighting control system were combined with empirical energy consumption data from individual tunable desk lamps for a probabilistic return on investment (ROI) analysis. Descriptive and correlational analyses were done to link employees’ environmental perceptions with energy consumption. Even for a modestly energy efficient office building that underwent a lighting retrofit in 2011, it is possible to recover the cost of an interactive lighting investment in nine years. Probabilistically, the rebate appears to be the most important factor in increasing ROI. Occupants perceived overall improvement to the lighting environment after desk lamps had been installed, and that a ‘blending’ had been achieved between task and overhead lighting. The paper proposes a generalizable mixed-methodology to evaluate potential savings. Interactive lighting systems are representative of future building systems that require more human interaction and are prone to irregular operational loads. This research may help facility managers find practical solutions based on existing and emerging technologies to leverage readily available data to aid decision-making processes.
