In this project the PI, building on her expertise in computer graphics, computational geometry, daylighting, and architectural design, will use computer graphics and daylight modeling to advance the science of architectural daylighting design, to promote the science and understanding of creativity in design, and to create innovative tools that allow designers to explore alternative designs and new technologies for improving the sustainability of their buildings. In particular, the PI will extend her prior results on efficient, interactive algorithms for qualitatively and quantitatively accurate interactive lighting simulation, to develop a "plug in" for global illumination and visualization that can be seamlessly incorporated into the early stages of design and that will work directly with meshes produced by commonly-used modeling programs. The new tool will be intended for use on a standard desktop computer by an experienced designer, who need not be an expert in daylighting technology or advanced graphical simulations. The PI will also develop, as a companion system, a full-scale, immersive environment in which multiple architectural designers, a designer and a client, or a teacher and student(s) can gather to experience animated visualizations of the natural illumination within a proposed design by controlling the time of day, the season, and the climate. Participants will also be able to interactively redesign the space, by changing the geometry and materials. This system will be developed and exhibited on the PI's campus in the Experimental Media and Performing Arts Center (EMPAC), leveraging the computational resources at the new Computational Center for Nanotechnology Innovations (CCNI), two state-of-the-art facilities that are unique to Rensselaer Polytechnic Institute.Broader Impacts: The tools to be developed in this project will incorporate fundamentally new interactive global illumination algorithms to solve for the challenging dynamic illumination conditions presented by daily and seasonal variations of the sun and sky. Techniques from the realm of parallel and distributed computing will be applied and extended, in order to facilitate online simulation and optimization during iterative architectural design. The architectural design process will thus become more effective and creative, enabling better exploitation of daylighting with a consequential reduction in the need for supplemental electric lighting, thereby leading to more energy-efficient building designs. The same framework will be applicable to other design problems that require complex physical simulation and visualization, including for example passive solar heating and cooling, acoustics, aerodynamic building envelopes, structural analysis, and general (non-architectural) design scenarios.

在这个项目中，PI将利用她在计算机图形学、计算几何、采光和建筑设计方面的专业知识，利用计算机图形学和日光建模来推进建筑采光设计的科学，促进设计中创造力的科学和理解，并创建创新工具，使设计师能够探索替代设计和新技术，以提高建筑物的可持续性。 特别是，PI 将扩展她之前在高效、交互式算法方面的成果，以实现定性和定量准确的交互式照明模拟，开发用于全局照明和可视化的“插件”，该插件可以无缝地融入到设计的早期阶段，并且将直接使用常用建模程序生成的网格。 新工具将供经验丰富的设计师在标准台式计算机上使用，而设计师无需是采光技术或高级图形模拟方面的专家。 作为配套系统，PI 还将开发一个全面的沉浸式环境，在该环境中，多个建筑设计师、设计师和客户、或教师和学生可以聚集在一起，体验自然照明的动画可视化。通过控制一天中的时间、季节和气候来提出设计。参与者还可以通过改变几何形状和材料以交互方式重新设计空间。 该系统将在 PI 校园的实验媒体和表演艺术中心 (EMPAC) 中开发并展示，利用新的纳米技术创新计算中心 (CCNI) 的计算资源，这两个最先进的设施分别是伦斯勒理工学院独有。更广泛的影响：该项目中开发的工具将采用全新的交互式全局照明算法，以解决太阳和天空的日常和季节变化所带来的具有挑战性的动态照明条件。 并行和分布式计算领域的技术将得到应用和扩展，以促进迭代架构设计过程中的在线模拟和优化。 因此，建筑设计过程将变得更加有效和富有创意，能够更好地利用日光，从而减少对补充电力照明的需求，从而实现更加节能的建筑设计。 相同的框架将适用于需要复杂物理模拟和可视化的其他设计问题，包括被动式太阳能加热和冷却、声学、空气动力学建筑围护结构、结构分析和一般（非建筑）设计场景。
