WebAssembly U-factor Calculator. Centre for Advanced Research in Building Science and Energy (CARBSE) at CEPT University has developed a wall and roof construction thermal transmittance or thermal Conductance (U - Factor) calculator. This is an online tool, to be accessed freely over internet. The values derived by the tool are specific for the city. WebU-factor is the rate at which heat can transfer through a material, and is the inverse of the R-value. A high performance window tends to have lower u-factor, indicating that less heat can transfer through the window, while a higher u-factor indicates a higher degree of heat transfer.
