断热玻璃 特指 易涂这类的,大量吸收红外线,而玻璃又基本上无色

应该是和隔热玻璃区分开的一个说法吧,我还在记小本本阶段,没开始理解

insulation做的好的话,用不了多少能源。比方说现在流行的zero energy homes. 我看一个例子说用几根蜡烛就可以加热整个house。

还可以考虑passive heating, 比方说如果有三层玻璃大窗子的话,冬天室内温度不用加热都很容易到26度(有太阳的时候),然后室内多...
Double-pane windows have an R-value ranging from 3 to 3.8, while triple-paned windows have an R-value of up to 7- 8, making them more effective at blocking heat flow. This means that replacing double-paned units with triple-paned windows reduces heating costs.

老房子了 insulation patch做再好 也很难做到零能耗,除非remodel
咱只能平衡一下性价比的分析咯


咱把目标回笼一下哈
目前房子是1000尺大理石+1500尺地毯flooring,风暖;很土的墙纸,popcorn天花
目标是 上个不吵不大风的供暖,换墙纸,换天花,budget八...
天花上的popcorn可以铲掉

大理石地面不值得打掉重做

地毯地面做地暖不好

方案,就是中国人的方案,water-baseboard-heater,是最佳方案,不要看他的能耗宣传,他的意思是费用最低,效果不错


风管不能拆除,夏天还需要制冷

----

这个我在中国做过,在加拿大也改造过自己的两套房子

我学的就是土木工程,干的也基本这个

天花上的popcorn可以铲掉
我想铲它好久了! 一直在等齐其他项目,不然收拾东西只为了弄天花 好像很浪费


嗯呐,我也觉得墙暖比较方便,但电好像架起来方便些,水暖得铺管道,暂时还不想拆墙 动结构

我再想想 还有没其他可以一起收拾的 计划好一起整,高效些

局部挖洞与修补可以解决管道问题,电力的也要新加线路
