U-value, R-value and λ-value – A brief explaination with Examples Within energy efficiency an important metric is the thermal transmittance; the U-value. The U-value describes the heat transfer through a construction with a 1 m² surface at a temperature differential of 1 °K. The unit of the U-value is therefore W/(m²K), where W=J/s. The U-value… Read more: Introduction to energy calculations
