ENVI-met BioMet
ENVI-met Biomet is a post-processing tool to calculate human thermal comfort indices based on your simulation data. It directly interacts with the ENVI-met output and lets you interactivly set the persons parameter, the Thermal Comfort Index and the range of calculation.
Thermal Comfort Indices provided
In the recent version 1.0, Biomet supports PMV/PPD (Predicted mean vote), PET* (Physiologal Equivalent Temperature) and UTCI* (Universal Thermal Climate Index), but more are likely to be integrated. (*: only available with the Professional license of Biomet). The indices vary in their level of complexity and therefore calculation time. 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. Compared to former version of ENVI-met, the calculation of Thermal Comfort Indices as a post-processing step allows to modify e.g. personal settings without running ENVI-met again.
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 sensefull. First you need valid ENVI-met simulation output, then you can calculate Thermal Comfort.
Running BioMet
A very basic and very rough guide on how to use BioMet can be found here: Biomet Quick-Start. This includes information on how to upgrade to the licensed version of BioMet.
