| 采用大直径光导纤维制备了轻质半透明混凝土板（TCP），测试了其抗压强度和导热系数，并利用SketchUp和EnergyPlusTM软件，建立了单间办公房屋模型，对比了TCP幕墙、砖墙与玻璃幕墙3种围护墙体对房屋能耗的影响.结果表明：TCP导热系数在021W/(m·K)左右，较其他常用幕墙材料（玻璃、砖）性能优越；TCP幕墙较玻璃幕墙冬季耗能大，但夏季能耗明显低于玻璃幕墙，总耗能约为玻璃幕墙的85%，保温效果总体优于玻璃幕墙；TCP幕墙年度能耗较玻璃幕墙具有明显优势，可以降低建筑的年度能耗，还可以降低电费成本；TCP幕墙内光导纤维体积分数越大，其冬季能耗越低，夏季能耗越大，且冬季能耗降幅普遍低于夏季增幅. |

| Abstract: |
| A series of translucent concrete panel(TCP) was prepared by using large diameter optical fiber(OF), and its compressive strength and thermal conductivity properties were measured. To investigate the energy efficient performance of the TCPs, one room office building model was built with SketchUp and EnergyPlusTM software packages. The influence of TCP curtain wall, brick wall and glass curtain wall on energy consumption was compared. The results show that the thermal conductivity of TCP is about 021W/(m·K), which is superior to other commonly used curtain wall materials such as glass and brick; TCP curtain wall consumes more energy than glass curtain wall in winter, while it consumes less energy than glass curtain wall in summer. The total energy consumption of TCP curtain wall is 85% of that of glass curtain wall. The annual energy consumption of TCP curtain wall is obviously less than that of glass curtain wall. The electricity cost of buildings can also be reduced. The volume fraction of optical fiber in TCP curtain wall the lower the energy consumption in winter and the greater the energy consumption in summer, and the reduction amplitude of energy consumption in winter is generally lower than the increase value in summer. |
