IECC隔热要求
I am currently in the early stages of designing a home and currently looking at Quonset huts as an alternative to stick framing. After looking over IECC for the region that I would like to build in it seems I would need an R value of 49 on ceilings and R15ish if I remember correctly on the walls. The question that I have is how, in a dome shaped Quonset hut (or other round "dome home" for that matter) would code delineate where the wall stops being a wall and starts being a ceiling. I would imagine that it would not be required to have R49 on the whole structure and that at some vertical point the R15 would need to transition to R49 to meet the ceiling insulation requirements, but I haven't found a concrete answer on this subject. My plan is to use closed cell spray foam for its water tight properties and would like to get rough estimates on cost, but there would obviously be a huge difference in applying a R49 layer throughout as appose to a R15 R49 hybrid. Any insight is appreciated.

以下是我的意见(原屋顶设计师):Quonset小屋100%的钢外部为房顶外墙不存在(除可控端外)
但我的意见无关唯一重要的是你本地代码官的意见调用本地代码局
本地代码允许时,使用比较等值R值会更好(或全表单R值)。
本地代码官不认为大楼百分之百像Martin那样屋顶, 但你想像JonR建议的那样全方位都等值R值, 探索的一条路是查看你是否可以使用ResCreckUA交换法显示全圆顶结构符合统一的R值:https://www.energycodes.gov/rescheck

混合闭合细胞泡沫以充分厚度保护水分,开立细胞泡沫以剩余期望R值,可能也合情合理
