What We Did and Why
RIC Solutions was engaged to assess and verify indoor air quality concerns at a major cinema complex following reports of persistent odours, condensation, and customer complaints about indoor comfort. With multiple theatres, and limited natural ventilation, the complex presented a high-risk environment for indoor air quality (IAQ) issues, particularly in the wake of recent wet weather and a history of moisture ingress.
Our client required independent, science-based assessment and ongoing monitoring to identify the cause of issues and support informed, cost-effective remediation decisions reducing business interruption.
Given the interruption to the venue, our work focused on discreet and data-driven environmental verification to guide remedial actions.
How We Approached It
RIC Solutions deployed a multi-phase assessment and remote air quality monitoring program, tailored to the building’s operational requirements and risk profile. This included:
- On-site investigation to assess moisture levels, HVAC function, air movement, and potential contamination sources
- Real-time remote air monitoring using discreet sensors in high-traffic areas to capture indoor environmental data over time
- Sampling and laboratory analysis for airborne mould spores, particulate matter (PM), carbon dioxide (CO₂), and volatile organic compounds (VOCs)
- Post-remediation verification (PRV) following localised intervention works in affected areas
All data was interpreted against relevant indoor air quality guidelines and standards, including those issued by Safe Work Australia and the WHO, as well as building performance benchmarks for thermal comfort and ventilation adequacy.
Key Findings
Our assessments identified several key contributing factors:
- Elevated humidity and inadequate dehumidification in some theatres, particularly those with high occupancy during long screening sessions
- Poor HVAC zoning and balancing, resulting in uneven temperature and airflow distribution
- Moisture ingress beneath floor coverings in older areas of the complex, contributing to microbial activity in concealed spaces
- Elevated CO₂ and VOC levels during peak operating hours, indicating insufficient ventilation and build-up of occupant-related emissions
Remote monitoring provided time-series data showing how air quality fluctuated during opening hours, cleaning cycles, and weather events—highlighting patterns not observable through snapshot testing alone.
Why It Matters
Indoor air quality is a critical factor in occupant wellbeing, particularly in venues like cinemas where people spend extended periods in confined spaces. By combining on-site expertise with remote sensing and scientific analysis, RIC Solutions was able to deliver rapid, accurate, and actionable insights that supported business continuity, customer confidence, and regulatory compliance.
