Abstract: This study looks at U-values and heat transfer for houses built in Libya, of which the majority studied were built in the 1970's when the locally produced building materials didn't consist of any insulating materials. Measurements of thermal conductivity of the various building materials were made using the Hot Disk method. Additionally, the researchers developed a theoretical model that could estimate U-values from measured thermal conductivity values. It was determined that U-values were quite high, and thus the researchers propose several suggestions to lower these values.
