Analysis of the Double Window in Saving Energy and Economical Efficiency in Nanjing in the Winter
MetadataShow full item record
With the rapid progress of the economy, heating in winter is widespread in the eastern area of China. According to the exterior-protected structure of buildings in Nanjing, the hourly and dynamic load of energy consumption during the time of heating in winter is simulated and calculated in the paper. Through calculations, the energy consumption of the different windows, walls and roofs is gained. By analyzing the results of these calculations, the conclusion that using a single frame-double plastic steel window can save energy by 37.68% is reached. As part of the economical efficiency analysis, an investment payback period is analyzed using the methods of static state and dynamic state. The analysis shows that by using single frame-double plastic steel window, the investment payback period is about 7 years.
