7.6.2 Select Validation Method. In order to determine the thermal environment’s ability to meet the defined criteria as outlined in Section 7.6.1 above, there are two methods (one described in Section 7.6.2.1 and the other in Section 7.6.2.2) that can be implemented. The first method of validating the thermal environment is to statistically determine occupant satisfaction through the evaluation of survey results. The sec- ond is to technically establish comfort conditions through the analysis of environment variables.
