此外，通过在第二墙体20设置至少一个可供光线穿透的采光口21，可使穿透玻璃幕墙11的一部分光线可经由采光口21进入室内，从而可保障室内自然光的强度，降低因设置第二墙体20而致使室内自然采光减弱的影响，降低照明设备的使用程度，降低改造建筑的能耗。
可选地，采光口21内可设置可启闭的采光窗，采光窗可选高性能采光窗。如此设置，可保障第二墙体20的隔热性能和气密性。
综上，本申请实施例提供的改造建筑，通过在玻璃幕墙11的内侧设置第二墙体20，以通过第二墙体20有效地阻隔穿透玻璃幕墙11的太阳光线进入室内，从而提高改造建筑的隔热性能；还通过在第二墙体20的内侧设置第一保温层22，以有效地提高第二墙体20的保温性能，从而保障并提高了改造建筑的隔热性能和保温性能；还通过在第二墙体20设置至少一个可供光线穿透的采光口21，以引导穿透玻璃幕墙11的光线一部分进入室内，从而保障了改造建筑的采光性能。因此，本申请实施例提供的改造建筑，可在不破坏玻璃幕墙建筑的既有结构的基础上，改善地具有较佳的采光性能、隔热性能和保温性能。
