Indoor Air Quality (IAQ) Assessment
Comprehensive Indoor Air Quality assessments, HVAC hygiene audits, VOC and microbial investigations, and continuous IAQ monitoring aligned with Singapore Standard SS 554:2016, NEA Guidelines, and BCA Green Mark requirements.
About This Service
Overview
Indoor Air Quality (IAQ) directly influences occupant health, productivity, and regulatory compliance for buildings across Singapore. With most office workers spending more than 90 percent of their time indoors, poor IAQ — driven by inadequate ventilation, microbial growth, volatile organic compounds, and HVAC system contamination — is a leading contributor to sick building syndrome, respiratory illness, and absenteeism. DASH Consult provides end-to-end IAQ services that help building owners, facilities managers, and employers protect their people while meeting Singapore Standard SS 554:2016, NEA Indoor Air Quality Guidelines, and the Workplace Safety and Health (General Provisions) Regulations.
Our IAQ methodology is built on accredited sampling protocols and a deep understanding of Singapore's tropical climate, ventilation engineering, and occupational hygiene science. We measure the full SS 554:2016 parameter suite — carbon dioxide, carbon monoxide, total volatile organic compounds (TVOC), formaldehyde, particulate matter (PM10 and PM2.5), respirable suspended particles, airborne bacteria and fungi, temperature, relative humidity, and air movement — using calibrated reference instruments and direct-reading sensors. Where exceedances are found, we trace them back to the source: HVAC filtration gaps, recirculation imbalances, contaminated condensate trays, building material off-gassing, occupant density, or external infiltration.
Beyond compliance, our IAQ programmes support BCA Green Mark certification, WELL Building Standard wellness scoring, and ESG reporting for sustainability-focused organisations. Whether you operate an office tower, school, hospital, manufacturing facility, data centre, or commercial complex, our team delivers defensible IAQ reports, prioritised remediation plans, and ongoing monitoring solutions that turn air quality from a hidden liability into a measurable asset.

Capabilities
Key Features
IAQ Assessment & SS 554 Compliance Audit
Full multi-zone measurement of every SS 554:2016 parameter — CO2, CO, TVOC, formaldehyde, PM2.5, PM10, microbial counts, temperature, humidity, and air movement — with regulator-ready reporting and source tracing.
VOC & Chemical Exposure Survey
Live TVOC mapping plus laboratory-grade sorbent tube and DNPH cartridge sampling for speciated VOCs and formaldehyde, benchmarked against SS 554, MOM Permissible Exposure Limits, and ACGIH TLVs.
Continuous IAQ Monitoring Programme
Calibrated IoT sensors with cloud dashboards, alerting, and quarterly trend reports for real-time IAQ visibility, BCA Green Mark scoring, WELL Building Standard ongoing monitoring, and ESG disclosure.
Green Mark & WELL Building Support
IAQ documentation, performance verification, and post-occupancy testing aligned with BCA Green Mark IAQ credit requirements and WELL Building Standard wellness scoring.
