Abstract: Lime-hemp concrete (LHC) is a sustainable construction material with a low environmental impact. In this study, the thermal properties of two lime-hemp mixes with varying levels of hemp were measured to analyze the material’s ability to be used on a larger scale in cold and wet climates. A TPS1500 Thermal Constants Analyser measured the thermal properties of the lime-hemp samples using the Transient Plane Source (TPS) method. Results showed that the mix with a higher hemp concentration was more desirable because of its low thermal conductivity. Also, thermal conductivity increased with relative humidity, so the use of LHC in dry climates would be the most beneficial.
