提高建筑物内部能量利用率就可降低能耗,下面是几种建筑用的节能材料:光敏材料用这种材料可制造一种像电器开关一样的可亮可暗的窗户。它可以使窗户透明,让冬天稀少的阳光全部照进来;也可以使
Energy efficiency can be reduced by increasing the internal energy efficiency of the building. Here are some energy-saving materials used in construction: Light-sensitive materials Use this material to create bright, dark windows like electrical switches. It can make the windows transparent, allowing all the scarce sunlight in winter to shine in; it can also make
