《加拿大国家建筑节能规范》是由加拿大国家研究院制定出版的，于１９９７年颁布实施。在该规范的附录Ｂ中列举了大量目前加拿大常见建筑围护结构的做法，并给出了相应的热阻值和传热系数，供设计人员查阅使用。这些围护结构多为节能型。现将这些围护结构进行概括、总结，... The Canadian National Building Energy Conservation Code was developed and published by the Canadian National Institute of Research and was promulgated and implemented in 1997. Appendix B of this specification lists a large number of current practices of common building envelopes in Canada, and gives the corresponding thermal resistance and heat transfer coefficients for use by designers. Most of these envelopes are energy-efficient. Now these envelope structures are summarized and summarized....
