The research objective of this Small Grant for Exploratory Research award is to prototype and validate an interactive daylighting tool that allows architects to explore alternative designs and new technologies to improve the sustainability of their buildings. Our hybrid global illumination rendering method combining radiosity and shadow volumes will be seamlessly incorporated into the early stages of design. We envision our tool as a plug-in to popular modeling packages used by experienced designers, who are knowledgeable but not necessarily experts in daylighting technology or advanced graphical simulations. We hypothesize that use of our rendering and visualization software will make the architectural design process more effective, creative, and satisfying and lead to more energy-efficient building designs. We will design and carry out a preliminary user study to test this hypothesis. Our framework will be compared with current design practice by measuring the breadth of designs considered as well as the efficiency of the final design.If successful, the results of this research will demonstrate the effective use of interactive global illumination algorithms and temporal maps for architectural design, including the use of non-intuitive complex specular window materials. The new tool will be used in architectural design studios and workshops to enhance creative thinking and broaden the number of criteria that can be considered and balanced during design. The project will engage graduate and undergraduate students in computer science, building technology, and architectural design. If successful, our system will improve the architect's ability to make effective use of daylighting and reduce the need for supplemental electric lighting, reducing consumption of non-renewable energy resources. The same framework can be applied to other design problems that require complex physical simulation and visualization, including passive solar heating and cooling, acoustics, aerodynamic building envelopes, and general (non-architectural) design scenarios.

这项探索性研究小额资助的研究目标是原型和验证一种交互式采光工具，使建筑师能够探索替代设计和新技术，以提高建筑物的可持续性。我们的混合全局照明渲染方法结合了辐射和阴影体积，将无缝地整合到设计的早期阶段。我们设想我们的工具作为一个插件到流行的建模包使用的经验丰富的设计师，谁是知识渊博的，但不一定是专家在采光技术或先进的图形模拟。我们假设使用我们的渲染和可视化软件将使建筑设计过程更有效，更有创意，更令人满意，并导致更节能的建筑设计。我们将设计并开展一项初步的用户研究来验证这一假设。我们的框架将通过测量所考虑的设计的广度以及最终设计的效率来与当前的设计实践进行比较。如果成功，这项研究的结果将证明交互式全局照明算法和时间地图在建筑设计中的有效使用，包括使用非直观的复杂镜面窗户材料。新工具将用于建筑设计工作室和工作坊，以增强创造性思维，并扩大设计过程中可以考虑和平衡的标准数量。该项目将招收计算机科学、建筑技术和建筑设计专业的研究生和本科生。如果成功，我们的系统将提高建筑师有效利用采光的能力，减少对补充电力照明的需求，减少不可再生能源的消耗。同样的框架也可以应用于其他需要复杂物理模拟和可视化的设计问题，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和一般（非建筑）设计方案。
