Designing Panelized Systems to Minimize Impact on Indoor Air Qualityin Tightly-Sealed BuildingsJohn C. LittleThe use of Structural Insulated Panels (SIPs) to create very tight building envelopes will help achieve PATH's goals of simultaneously reducing the environmental impact and improving the energy efficiency of new and existing homes. Typically, SIPs use oriented strand board and rigid foam in a multi-layered, sandwich-like structure. Although environmental advantages make these panelized systems very attractive, the tighter building envelope construction may degrade indoor air quality. For example, formaldehyde, other aldehydes, and terpene hydrocarbons are commonly found in new manufactured and site-built houses, and these compounds are associated with strong sensory irritation. The release of these contaminants must therefore be taken into account when designing homes constructed with SIPs. A diffusion model that predicts emissions from single-layer materials has recently been developed and successfully validated. A logical and very promising extension of this approach is to apply the model to predict emissions from multi-layer systems like SIPs. This research will characterize emissions from the individual layers used in the fabrication of SIPs; independently measure the model parameters for the different material layers; validate the single-layer model by comparing predicted emissions to observations obtained in experimental chamber studies; extend the single-layer model to a composite multi-layer model with boundary conditions appropriate for SIPs construction; validate the multi-layer emissions model for SIPs, with and without the presence of an installed barrier material; and use the multi-layer model to optimize the position and properties of barrier materials that can be used to significantly reduce emissions from other advanced panel systems.This research builds on an existing and successful partnership with Alfred Hodgson, of the Environmental Energy Technologies Division at Lawrence Berkeley National Laboratory, and forges a new collaboration with Dr. Daniel Dolan, Professor and Director of the Center for Integrated Systems in Housing at Virginia Tech, thereby ensuring rapid translation of fundamental research into practical applications.

设计镶板系统以最大程度地减少对室内空气质量的影响，紧密密封的建筑物John C. Littlethe使用结构绝缘面板（SIP）来创建非常紧密的建筑物信封，这将有助于实现同时降低环境影响并改善新房屋和现有房屋的能源效率的目标。 通常，SIP在多层的三明治结构中使用定向链板和刚性泡沫。 尽管环境优势使这些镶板系统非常有吸引力，但更紧密的建筑包构建可能会降低室内空气质量。 例如，在新的制造和现场建造的房屋中通常发现甲醛，其他醛和萜烯碳氢化合物，并且这些化合物与强烈的感觉刺激有关。 因此，在设计用SIPS建造的房屋时，必须考虑这些污染物的释放。 最近已经开发并成功验证了一种预测单层材料排放的扩散模型。 这种方法的逻辑且非常有前途的扩展是应用模型来预测SIP等多层系统的排放。 这项研究将表征SIP制造中使用的各个层的排放；独立测量不同材料层的模型参数；通过将预测的排放与在实验室研究中获得的观测值进行比较，验证单层模型。将单层模型扩展到具有适合SIPS结构的边界条件的复合多层模型；验证有或没有安装的屏障材料的SIP的多层排放模型；并使用多层模型来优化可用于大大减少其他高级面板系统排放的屏障材料的位置和特性。这项研究基于与Alfred Hodgson的现有并成功合作，该公司的环境能源技术部门的劳伦斯伯克利伯克利（Lawrence）伯克利（Lawrence）伯克利（Lawrence）伯克利（Berkeley）国家实验室的合作，并在霍尔克利（Lawrence确保将基本研究快速转化为实际应用。
