Lighting simulation tools are extending the functionality of Building Information Modeling (BIM) authoring software applications to support the lighting design analysis of buildings. Although such tools enable quantitative and qualitative analysis and visualization of indoor lighting, they do not provide an interactive environment between users and the design context. Moreover, their visualization environments do not allow users to experience visual phenomena such as glare. In addition, lighting energy consumption generated from traditional tools is often separated from the 3D virtual context of the building. Therefore, an incorrect interpretation by designers regarding the relationship between their desirable lighting design and energy feedback may occur. This research proposes a method and develops a BIM-based lighting design feedback (BLDF) prototype system for realistic visualization of lighting condition and the calculation of energy consumption. The results of a case study revealed that BLDF supports design stakeholders to better perceive and optimize lighting conditions in order to achieve a higher degree of satisfaction in terms of lighting design and energy savings for future occupants. The developed system utilizes an interactive and immersive virtual reality (VR) environment to simulate daylighting and the illumination of artificial lights in buildings and visualizes realistic VR scenes using head mounted displays (HMD). BLDF allows users to interact with design objects, to change them, and to compare multiple design scenarios, and provides real-time lighting quality and energy consumption feedback.

集成建筑信息模型和虚拟现实开发引擎，用于建筑室内照明设计

照明模拟工具正在扩展建筑物信息建模（BIM）创作软件应用程序的功能，以支持建筑物的照明设计分析。尽管此类工具可以对室内照明进行定量和定性分析和可视化，但它们无法在用户和设计环境之间提供交互式环境。而且，他们的可视化环境不允许用户体验诸如眩光之类的视觉现象。此外，传统工具产生的照明能耗通常与建筑物的3D虚拟环境分开。因此，设计师可能会对他们所需的照明设计和能量反馈之间的关系做出错误的解释。这项研究提出了一种方法，并开发了一种基于BIM的照明设计反馈（BLDF）原型系统，用于逼真的照明条件可视化和能耗计算。案例研究的结果表明，BLDF支持设计利益相关者更好地感知和优化照明条件，从而在照明设计和节能方面为未来的居住者实现更高的满意度。开发的系统利用交互式沉浸式虚拟现实（VR）环境来模拟建筑物中的日光和人造光照明，并使用头戴式显示器（HMD）可视化逼真的VR场景。BLDF允许用户与设计对象进行交互，对其进行更改以及比较多个设计方案，
