Indoor air quality testing at Theater M

Theater M

Theaters present an air quality challenge that most commercial buildings don't - occupancy that swings from empty to packed within hours, spaces designed for acoustics rather than ventilation, and a mix of front-of-house and back-of-house environments that each behave differently. When Theater M in Mechelen needed to understand whether their indoor air quality held up against regulation and against the expectations of the people using the building, they brought Airscan in to find out. The assessment ran for three months, long enough to build a picture that a spot measurement never could.

The Brief

Theater M needed a structured indoor air quality assessment to evaluate conditions across the building and establish compliance with applicable indoor air quality regulations, with real-time visibility for building managers throughout the monitoring period and a full report at the close.

What We Did

Airscan deployed a monitoring network across Theater M and ran a continuous assessment over a three-month period, tracking how indoor air quality evolved across different spaces and conditions throughout that time. Building managers had access to real-time data throughout, allowing them to respond to conditions as they arose rather than waiting for a retrospective report. At the close of the monitoring period, Airscan produced a full report covering threshold analysis, conclusions drawn from three months of data, and specific recommendations for future improvements.

How It Works

A three-month window captures what a single-day or single-week measurement misses — how air quality shifts between a quiet Tuesday rehearsal and a sold-out Friday evening, how different seasons and occupancy patterns interact with the building’s ventilation, and where the consistent problem areas are versus the incidental ones. Real-time access to that data during the period means building management isn’t passive in the process; they can act on what they’re seeing while the assessment is still running rather than receiving everything at the end.

Outcomes

The assessment produced a full compliance and quality picture for Theater M, along with a concrete set of recommendations for improvement. The monitoring network remained in place after the three-month assessment concluded, giving the theater continued visibility into their indoor air quality on an ongoing basis.
