While UTCI is regression based and quick, PMV requires the iterative solution of one energy balance equation and PET requires the solution of two of them and is hence much more calculation time expensive.

**However, it is important to understand, that a proper Thermal Comfort Index can only be calculated if the microclimate data used are correctly and/or sense-full. First you need valid ENVI-met simulation output, then you can calculate Thermal Comfort.** | **However, it is important to understand, that a proper Thermal Comfort Index can only be calculated if the microclimate data used are correctly and/or sense-full.

This is the big and holy question. The fact, that BIO-met already supports 4 of them gives a clue, that there is no generally accepted answer. | This is the big and holy question. The fact, that BIO-met already supports 4 of them gives a clue, that there is no generally accepted answer. | ||
