    This study assessed metrics available in standards (ISO7730:2006, ASHRAE55:2017, ISO17772:2018, EN16798:2019) and certifications (WELL, BREEAM, LEED, DGNB). A set of measurable IEQ parameters and indicators for short and long-term evaluation were identified. The standards propose certain parameters: operative temperature, CO2 concentration, illuminance, noise and RH directly as KPIs, while combining certain parameters in KPIs such as predicted mean vote (PMV), predicted percentage dissatisfied (PPD) and percentage dissatisfied. Although the metrics are clearly defined, there is no clear methodology for benchmarking, neither one single indicator for assessing the IEQ. Thus, an assessment on a real set of measurements built upon the findings could determine indicators’ applicability with the aim of creating an IEQ benchmarking methodology for buildings while highlighting a relationship between KPIs and energy use.
