In recent times, concerns over global warming and climate change have been influencing every aspect of our day-to-day activities, and built environment is no exception. Buildings consume up to about 40% of our total national energy demand and Canada has one of the highest per-capita energy consumption in the world. The most cost-effective way to enhance the energy efficiency of built environment is the addition of thermal insulation in exterior building envelopes. Quite naturally, the newly updated National Energy Code of Canada for Buildings (NECB) and various green building rating systems (LEED, Net-Zero etc.) are promoting increased use of thermal insulations in exterior building envelope constructions. Consequently these developments are providing fresh impetus to the research on high-performance and environment-friendly thermal insulations.****** The principle goals of this research program are to develop and integrate environment-friendly high-performance thermal insulations in Canadian building envelope constructions. The primary focus of the first five years of this research program will be on the vacuum technology based vacuum insulation panel (VIP) and nanoporous aerogel insulation. Aerogel based thermal insulations have about two times and VIPs have about five to ten times higher thermal resistivity than closed-cell foam insulation. ****** There are four major tasks that will be carried out during the next five years and they are: (1) development of alternative low-cost core materials for VIPs, (2) development of bio-based VIPs from renewable bio-resources, (3) determination of long-term performance of VIPs, and (4) assessment and management of hygrothermal (i.e. moisture and thermal) performance of novel and highly insulated building envelopes.****** The research direction of this program is motivated by my involvement with several national and international organizations/associations (ULC, SCC, ISO, ASTM, IEA-EBC etc.).The outcomes from this research program will have profound impacts on both Canadians and Canadian construction industry. The outcomes will help Canadians to build more energy efficient buildings, reduce housing and heating costs, and mitigate the elements causing climate change, and also provide inexpensive, environment-friendly and high-performance thermal insulation technologies to the Canadian construction industry.*****

最近，人们对全球变暖和气候变化的担忧一直在影响我们日常活动的各个方面，而建立环境也不例外。建筑物的消费量大约是我们国家能源总需求的40％，加拿大是全球人均能源消耗最高的之一。提高建筑环境的能源效率的最具成本效益的方法是在外部建筑物信封中添加热绝缘。自然而然地，新更新的加拿大国家能源法规（NECB）和各种绿色建筑物评级系统（LEED，Net-Zero等）正在促进外部建筑构造构造中对热绝缘的使用增加。因此，这些事态发展为有关高性能和环境友好的热绝缘的研究提供了新的动力。******该研究计划的主要目标是在加拿大建筑中开发和整合环境友好的高性能热绝缘量信封结构。 该研究计划的头五年的主要重点将放在基于真空技术的真空绝缘板（VIP）和纳米多孔气凝胶绝缘层上。基于气凝胶的热绝缘量大约有两次，而VIP的热电阻率大约是闭孔泡沫绝缘材料的五到十倍。 ******将在未来五年内执行四个主要任务，它们是：（1）开发替代性的低成本核心材料以供VIP生物资源，（3）确定VIP的长期性能，以及（4）新颖和高度绝缘建筑信封的湿热（即水分和热量）性能的评估和管理。******该计划是由我参与几个国家和国际组织/协会（ULC，SCC，ISO，ASTM，IEA-EBC等）的动机。该研究计划的结果将对加拿大和加拿大建筑业产生深远的影响。这些结果将帮助加拿大人建造更高效的建筑物，降低住房和供暖成本，减轻导致气候变化的要素，并为加拿大建筑业提供廉价，环境友好和高性能的热绝缘技术。*** *** *** **
