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

本提案中计划的研究旨在表征和扩展由渥太华的Kott集团为偏远的北方地区开发的制造建筑系统的性能; 142套房屋已交付给努纳武特住房公司，目前正在建造中。北方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、恶劣的气候、偏远的社区和高能源成本。在严酷的冬季，墙壁、屋顶和地板部件经受室内和室外温度和湿度的巨大差异，这可能导致这些部件的劣化和/或故障，需要昂贵的维修和维护以及更高的能源账单，并且可能使居住者感到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.
