The design of heating, refrigeration, and air-conditioning equipment for buildings as well as components of the building thermal envelope depends on the principles of heat transfer theory. Heat transmission properties, such as thermal conductivity, resistivity, conductance, and resistance, for building materials and thermal insulation are important for the determination of heat transmission coefficients for these applications. The NIST Database on Heat Conductivity of Building Materials provides a valuable reference for building designers, material manufacturers, and researchers in the thermal design of building components and equipment. NIST has accumulated a valuable and comprehensive collection of thermal conductivity data from measurement...
