Hygrothermal performance of a building envelope system using structural insulated panels (SIP) subjected to Nunavut climatic conditions

本提案中的研究计划旨在描述和扩展由渥太华Kott集团为偏远北部地区开发的人造建筑系统的性能；已经向努纳武特住房公司交付了142套住房，目前正在建造中。北部地区面临着一系列独特的设计挑战，包括运输建筑材料的高成本和困难、气候的严酷、社区的偏远和高成本的能源。在严酷的冬季，墙壁、屋顶和地板组件受到室内和室外温度和湿度的巨大差异，这可能导致这些组件的恶化和/或故障，需要昂贵的维修和维护以及更高的能源账单，并可能给居住者带来不适和可能的健康症状。

The research planned in this proposal aims to characterize and extend the performance of a manufactured building system developed by the Kott group in Ottawa for remote northern regions; 142 homes have been delivered to the Nunavut Housing Corporation and are currently being built. Northern regions face a series of unique design challenges including high cost and difficulty in transporting construction materials, the harshness of the climate, remoteness of the communities and high costs of energy. In the harsh winters, wall, roof, and floor components are subjected to large differences in indoor and outdoor temperatures and humidity, which can lead to deterioration and/or failure of these components requiring costly repairs and maintenance and higher energy bills, and likely to discomfort and possibly health symptoms to the occupants.
