Comprehensive synthesis of IEQ literature

Study	Region	Building type/scale	Primary IEQ focus	Key findings	Identified limitations
Bennett et al. (2022)	New Zealand	National / multi-building	IAQ and public health	Indoor pollutant levels frequently exceed outdoor levels; ventilation is linked to infection and health risk mitigation	Absence of binding IAQ standards; limited systematic monitoring
Elnaklah, Walker and Natarajan (2021)	Jordan	Non-residential green buildings	Ventilation, IAQ, thermal comfort	Objective improvements in thermal conditions and selected IAQ metrics; energy–ventilation trade-offs evident	Weak alignment between measured and perceived comfort; operational variability
Sant’Anna et al. (2018)	Brazil	Commercial (LEED vs conventional banks)	Perceived IEQ and satisfaction	Employees in green buildings report higher IEQ and corporate satisfaction; no significant difference for customers	Small sample; subjective measures; potential certification awareness bias
Scutaru and Witterseh (2020)	European Union	Construction materials	VOC emissions regulation	Harmonised VOC testing (EN 16516; EU-LCI values) improves health protection potential	Limited mandatory enforcement; incomplete EU-wide adoption
Ade and Rehm (2020)	New Zealand	National housing stock	Healthy housing governance	IEQ mechanisms are largely prescriptive and compliance-based; limited post-occupancy verification; overheating is overlooked	Weak enforcement; voluntary scheme limitations; static assessments
Kabir and Morgan (2021)	New Zealand	Planning and policy system	Strategic environmental assessment	Environmental assessment is procedurally uneven and weak in monitoring and health integration	No explicit SEA mandate; fragmented institutional coordination
Rasheed and Rotimi (2022)	New Zealand	Office buildings (Auckland and Wellington; n = 149)	Worker IEQ preferences	Workers prefer mixed-mode ventilation and lighting, more fresh air, moderate temperature, reduced noise and partial control over IEQ; demographic factors influence preferences	Conducted in summer only; limited to Two cities; perception-based (no objective measurements)
