Operational performance in built environments is mostly assessed through indoor environmental quality (IEQ)

water consumption

and energy consumption data to foster improvement-oriented strategies. This study investigates the IEQ and energy performance of residential college buildings (RCBs)

including a LEED Silver-certified building

at a Louisianan university in the United States. Variations in occupant satisfaction

hygrothermal conditions

air quality

and energy metrics were assessed across seasons. Comparative evaluations of LEED-certified and non-certified RCBs in humid subtropical climates are scarce

highlighting the need for further exploration. The study employs subjective

objective

and integrated IEQ evaluation models

alongside energy performance evaluations using conventional Energy Use Intensity (EUI) and a novel Energy Utility Quality (EUQ) metric developed for climates like Louisiana’s. An extended IEQ model integrating energy performance with subjective and objective components is also introduced. Findings highlight significant underperformance in acoustic conditions and high humidity levels

posing risks to occupant comfort and health. While the LEED-certified building excelled in the various IEQ performance metrics adopted

its highest EUI attainment and intermediate EUQ ranking in relation to other buildings point to operational inefficiencies requiring targeted intervention. This research underscores the value of holistic IEQ and energy performance evaluations in enhancing occupant comfort

operational efficiency

and sustainability in student housing. The introduced metrics serve as an enhanced pre-audit tool

enabling facility managers to evaluate building performance effectively and make informed decisions. Future studies shall apply these metrics beyond RCBs.
