The effect of the thermal conductivity coefficients of building materials according to different sources on the thermal load and carbon dioxide emissions of the building

Energy saving is one of the challenges of today. In recent years, growing concerns about the environmental impacts of energy consumption and global warming has doubled the importance of this issue. Meanwhile energy consumption in construction sector is so high that saving even as little as possible in this section will have significant effect on efficiency rate of no renewable sources. Accurate measurement of thermal conductivity has an important role in determining the calculations of cooling and heating loads of buildings according to different climates. Considering multiple relevant parameters in energy consumption with no application of simulating tools cannot permit reasonable decisions on designing building parts. In this research, the annual energy consumption of an office building located in the climate of Yazd city has been simulated and compared by Design Builder.
