CAREER Development Performance Lignocellulosic Composites

项目摘要

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.

这个教师的早期职业发展（职业）项目将开发系统的分析解决方案，以准确设计，构建和评估瓦楞纸核木质纤维素式三明治面板，以构建信封组件，以作为净零能源构建的潜在解决方案。建筑物包络的组成部分影响其结构和湿润的性能，并确定建筑物的运营能量消耗；减少建筑物的运营能源的替代设计和材料将满足我们国家准备就绪的净零建筑物的目标。基于复合板理论的模型将考虑到设计木质纤维素三明治面板时瓦楞纸核的双向波动。该模型将定义设计夹心面板复杂芯的形成极限。项目还将评估用于住宅墙应用的全尺寸三明治面板结构和湿热性能。该职业项目的长期教育目标是准备新一代的工程师从木质纤维纤维中认识可持续建筑材料的工程师，并配备了知识，以设计和制造基于生物的复合产品，用于在净零能源建设中建造信封。美国主要能源的百分比是在建筑领域消耗的，其中房屋占54％，商业建筑占46％。住宅建筑对在二氧化碳等效物中测得的美国温室气体（GHG）排放量贡献了17％，其中空间供暖和冷却占温室气排放的37％。美国联邦政府的目标是到2015年，到2030年，到2015年，零净能源商业建筑和住宅建筑物。该研究建议通过使用套房化的系统通过新设计概念来推进可持续建筑的科学，以满足住宅建筑的满足建筑法规的结构和能源需求。多功能，轻巧的3D木质纤维素面板的性能将优于当前使用的材料作为建筑包络组件，并允许创新的镶板结构，这将减少我们未来房屋的运营能源的消耗并刺激房屋建筑行业。考虑到对绿色建筑材料的需求增加（预计未来五年的年增长率为13％），补充基于商品的基础设施的增值产品将有助于振兴森林产品行业的细分市场。
