The Brief
KPJ Klang needed a thorough indoor air quality assessment covering their hospital building, with findings substantiated by both measurement data and occupant input, and actionable recommendations for any conditions falling short of acceptable standards.
What We Did
Airscan conducted the assessment through a combination of walkthrough inspections, occupant interviews, and instrumented monitoring. Real-time IAQ sensors were deployed at three sampling locations for continuous 24-hour monitoring throughout the assessment period, capturing how air quality conditions evolved across different times of day and occupancy levels. Occupant interviews ran alongside the physical assessment, allowing the team to cross-reference instrument readings with firsthand accounts of comfort and symptoms from the people working in the building.
How It Works
Walkthrough inspections identify the physical and operational factors that shape indoor air quality – ventilation design, potential contamination sources, maintenance practices, space usage – while instrument monitoring captures what those factors are actually producing in the air. Running both in parallel, and layering in occupant interviews, produces a three-way picture that is considerably more reliable than any single method alone. The 24-hour monitoring window at each location is particularly important in a hospital setting, where occupancy and activity patterns shift substantially between day and night shifts and conditions can look very different depending on when you measure.
Outcomes
The assessment met its stated objectives, producing a clear view of indoor air quality conditions across the facility and a set of proposed rectification works for areas requiring improvement. The process also served an awareness function, introducing the concept of sick building syndrome to hospital occupants and giving staff a more informed understanding of the relationship between their indoor environment and their wellbeing.
