New method improves accuracy of thermal comfort index calculation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a more accurate method for calculating the Universal Thermal Climate Index (UTCI), a key metric for human thermal comfort. This new approach utilizes sparse regression with orthogonal polynomials, specifically Legendre polynomials, to create an approximation that is both computationally efficient and numerically stable. The method significantly reduces errors compared to the standard polynomial approximation, particularly large errors, and demonstrates robust generalization through testing on a large portion of the data.

    Approximating the universal thermal climate index using sparse regression with orthogonal polynomials

    arXiv:2508.11307v3 Announce Type: replace-cross Abstract: The Universal Thermal Climate Index (UTCI) is a measure of thermal comfort that quantifies how humans experience environmental conditions. Due to its robustness and versatility as a bioclimatic indicator, it has been exten…
