The most important factor in the worldwide problem of global warming is the emission of carbon dioxide. The 23% of carbon dioxide emissions generated by building construction must be reduced. Reduction in thermal conductivity, especially via improved insulation, is the most basic factor for decreasing energy consumption. Therefore, accurate and continuous thermal conductivity measurements are important in saving energy. This study presents methods for investigating thermal conductivity measurement and compares three methods: the heat flow meter, laser flash analysis, and thermal conductivity analyzer.
