This Faculty Early Career Development (CAREER) project will develop a systematic analytical solution to accurately design, build, and evaluate corrugated-core lignocellulosic sandwich panels for building envelope components as a potential solution for net zero energy construction. Components of a building envelope influence its structural and hygrothermal performance and determine a buildings consumption of operational energy; alternative designs and materials that reduce a building's operational energy will meet our nation's goal of market-ready, net-zero buildings. Model based on composite plate theory will account for bidirectional undulations of a corrugated-core in designing a lignocellulosic sandwich panel. The model will define the forming limits for designing the complex core of a sandwich panel. Project will also evaluate fullsize sandwich panel structural and hygrothermal performance for residential wall applications. The long-term educational goal of this CAREER project is to prepare new generation of engineers cognizant of sustainable building materials from lignocellulosic fibers and equipped with the knowledge to design and manufacture bio-based composite products for building envelopes in a net zero energy construction.Forty percent of US primary energy was consumed in the buildings sector, of which homes accounted for 54 percent and commercial buildings accounted for 46 percent. Residential buildings contribute 17 percent to the total US greenhouse gas (GHG) emissions measured in carbon dioxide equivalents, of which space heating and cooling account for 37 percent of GHG emissions. The US federal government has a goal of market-ready, net-zero energy commercial buildings by the year 2015 and residential buildings by 2030. The study proposes to advance the science of sustainable buildings through new design concepts using panelized systems for residential construction to meet structural and energy requirements of the building codes. Performance of multi-functional, lightweight, 3-D lignocellulosic panels will be superior to currently used materials as building envelope components and allow innovative panelized construction which will reduce the consumption of operational energy of our future homes and stimulate the home building industry. Considering an increased demand for green building materials (13 percent annual growth predicted in next five years), value-added products that complement commodity-based infrastructure will contribute to revitalizing segments of the forest products industry.

该教师早期职业发展（CAREER）项目将开发系统分析解决方案，以准确设计、构建和评估建筑围护结构组件的波纹芯木质纤维素夹芯板，作为净零能耗建筑的潜在解决方案。建筑围护结构的组成部分影响其结构和湿热性能，并决定建筑的运行能源消耗；减少建筑物运行能源的替代设计和材料将实现我们国家的市场就绪、净零建筑的目标。基于复合板理论的模型将在设计木质纤维夹芯板时考虑波纹芯的双向波动。该模型将定义设计夹芯板复杂芯材的成形限制。项目还将评估住宅墙壁应用的全尺寸夹芯板结构和湿热性能。该职业项目的长期教育目标是培养新一代工程师，了解木质纤维素纤维的可持续建筑材料，并具备设计和制造用于净零能耗建筑围护结构的生物基复合材料产品的知识。美国40%的一次能源消耗在建筑领域，其中住宅占54%，商业建筑占46%。以二氧化碳当量计算，住宅建筑占美国温室气体 (GHG) 排放总量的 17%，其中供暖和制冷占温室气体排放量的 37%。美国联邦政府的目标是到 2015 年实现净零能耗商业建筑投入市场，到 2030 年实现住宅建筑。该研究建议通过新的设计理念，使用住宅建筑面板系统来满足建筑规范的结构和能源要求，从而推进可持续建筑的科学发展。多功能、轻质、3D 木质纤维素面板的性能将优于目前用作建筑围护结构组件的材料，并允许创新的面板结构，这将减少我们未来住宅的运行能源消耗并刺激住宅建筑行业。考虑到对绿​​色建筑材料的需求增加（预计未来五年年增长率为 13%），补充商品基础设施的增值产品将有助于振兴林产品行业的各个领域。
