Compared to the US $ 100-200,000 it costs to build a house, this is marginal, not to mention the fact that in the future the owner will save big bucks on heating and / or air conditioning. But builders are still resisting. The reason they give is that if this US $ 1000 is added to the costs of building new homes, then they will be $ 1000 less competitive compared to old houses!
這 1,000 元比起動輒 10 到 20 萬美元的房屋建造費用實在微不足道，何況日後還可以為屋主省大錢，但建商就是不樂意，他們的理由是，如果新屋要多花這 1,000 元成本，就等於比舊屋少了 1,000 元的競爭力！
