CAREER: Designing Healthy and Energy-Efficient Buildings Using Computational Fluid Dynamics

PI建议开发一种新的CFD代码，该代码将预测室内和室外空气空间的耦合通风行为，包括物种（污染物，化学试剂）传输。 然后，她将耦合这与大规模的建筑能源模拟程序（已经存在），不包含复杂的通风能力，除非在能量平衡的基础上。 验证、测试和优化作为设计工具的这个计算“系统”是拟议工作的主要部分。潜在的影响包括可靠的设计工具和健康和节能建筑的指导方针。 此外，该理论可用于设计化学或生物制剂攻击的缓解策略，例如确定对制剂释放做出快速反应的最佳传感位置，激活合适的通风系统为居住者创建安全区，以及提供合适的手段在攻击后清洁建筑物。 它还将有助于在设计阶段将建筑师和工程师更建设性地聚集在一起。 该研究的教育贡献将包括两个新的课程，针对建筑和工程专业的学生在综合建筑系统设计和在建筑系统设计中使用计算流体动力学领域。

The PI is proposing to develop a new CFD code that will predict the coupled ventilation behavior of indoor and outdoor airspaces, including species (pollutants, chemical agents) transport. She will then couple this with large scale building energy simulation programs (already in existence) that do not contain sophisticated ventilation capabilities except on an energy balance basis. Validation, testing, and optimization of this computation "system" as a design tool is a major part of the proposed effort. Potential impacts include reliable design tools and guidelines for healthy and energy efficient buildings. In addition, the theory can be used to design mitigation strategies for chemical or biological agent attacks, such as determining the best sensing positions for quick responses to agent releases, activation of suitable ventilation systems to create a safe zone for occupants, and provision of suitable means to clean the buildings after an attack. It will also serve to bring architects and engineers more constructively together at the design phase. The education contribution of the research will include two new courses directed at architecture and engineering students in the areas of integrated building systems design and in the use of computational fluid dynamics in building systems design.
