目前，越来越严格的能源政策、不断上涨的能源价格以及对积极企业形象的渴望，成为跨国公司减少工厂能源消耗的动力。本文采用完整的建筑能耗模拟与优化框架，对传统的北光屋顶的价值进行了定量研究和讨论。研究结果表明，北光系统在多个气候区均能产生积极的建筑能源性能，包括：(1)湿润亚热带气候；半干旱大陆；(3)地中海;（四）亚热带高原。例如，在亚热带高原气候区，北光屋顶的建筑能耗比传统的平屋顶低54%。基于这些积极的发现，本文进一步提出了一个优化框架，改变北光屋顶的形状，以进一步提高其能源性能。为了定量地保证高概率找到满意的设计，同时减少计算处理时间，在方案中引入了有序优化。亚热带高地的案例研究表明，优化的北向屋顶形状进一步降低了26%的建筑能耗。所提出的评估和优化框架可用于设计具有集成北极光屋顶的工厂，旨在提高能源效率，同时保持环境居住者的舒适度。
Increasingly strict energy policies, rising energy prices, and a desire for a positive corporate image currently serve as incentives for multinational corporations to reduce their plants’ energy consumption. This paper quantitatively investigates and discusses the value of a traditional north-light roof using a complete building energy simulation and optimization framework. The findings indicate that the north-light system yields positive building energy performance for several climate zones, including: (i) Humid Subtropical; (ii) Semiarid Continental; (iii) Mediterranean; and (iv) Subtropical Highland. In the Subtropical Highland climate zone, for example, the building energy consumption of a north-light roof is up to 54% less than that of a conventional flat roof. Based on these positive findings, this paper further presents an optimization framework that alters the north-light roof shape to further improve its energy performance. To quantitatively guarantee a high probability of finding satisfactory designs while reducing the computational processing time, ordinal optimization is introduced into the scheme. The Subtropical Highland case study shows further energy building consumption reduction of 26% for an optimized north-light roof shape. The presented evaluation and optimization framework could be used in designing a plant with integrated north-lights roof that aim at energy efficiency while maintaining environmental occupant comfort levels.
