自动遮阳和综合照明控制系统被用于建筑物中，以节省电能和提高居住者的舒适度。这些系统有助于有效利用室内空间的有用日光，通过防止眩光和过热，同时保持足够的照度水平，有利于居住者的健康、福祉和生产力。实施开环遮阳和综合照明控制的实用程序包括三个部分：(i)实时可靠地估计天空条件，（ii）根据室外条件确定室内日光指标，以及（iii）将指标纳入盲和综合照明控制技术。本文综述了开环遮阳和综合照明控制策略的实验研究。本文的目的是分析各种日光预测方法的性能和可行性，以及它们在控制百叶窗和综合照明系统中的应用。该综述主要集中于采用实时日光估计方法的仿真辅助开环控制技术。该审查确定了当前的挑战，建议了改进的领域，并为未来的研究提供了重要的空间。本文的结论是，与传统的自动盲和照明控制系统相比，改进和改进的开环系统更适合作为一种替代方法。先进的开环控制系统以及校准模拟能够减少调试后的错误，允许轻松监控系统并更广泛地预测日光。
Automated shading and integrated lighting control systems are being used in buildings for electrical energy savings and improve occupant's comfort. These systems facilitate effective utilization of useful daylight in interior spaces that benefit an occupant's health, well-being, and productivity by preventing glare and overheating while maintaining the adequate illuminance levels. The pragmatic procedure to implement open loop shading and integrated lighting control comprises three parts: (i) a reliable estimation of sky conditions on real-time basis, (ii) determining indoor daylight metrics using outdoor conditions, and (iii) incorporating the metrics in the blind and integrated lighting control techniques. This paper presents a review of experimental studies done on open-loop window shade and integrated lighting control strategies. The aim of this paper is to analyse the performance and feasibility of various daylight prediction methods and their application in controlling blinds and integrated lighting system. The review mainly focuses on simulation assisted open loop control techniques that employ real-time daylight estimation methods. The review identifies the current challenges, recommends areas for improvement, and provides significant scope for future research. The paper concludes that modified and improved open loop system are more competent as an alternative compared to the conventional methods for automated blind and lighting control systems. Advanced open-loop control systems along with calibrated simulations have the capability to reduce post commissioning errors, allow easy monitoring of the system and predict daylight more extensively.
