Indoor Air Quality (IAQ) Assessment Services

At Western Health & Safety (WHS), we understand the critical importance of maintaining optimal Indoor Air Quality (IAQ) for the health, comfort, and productivity of building occupants. Our IAQ assessments are grounded in a robust framework of published protocols and industry standards, ensuring comprehensive and reliable evaluations.
​

Our Approach to IAQ Assessments

WHS employs a systematic approach to IAQ assessments, utilizing a variety of recognized protocols to guide our process. We adhere to standards such as:
  • WELL Building Standard: Focused on enhancing human health and well-being through better building design and operation.
  • ANSI/ASHRAE Standards 62.1 and 62.2: Benchmarks for ventilation system design and acceptable indoor air quality.
  • Alberta Infrastructure Guidelines: Specific to government-owned and supported infrastructure, ensuring compliance with local regulations.
These standards provide a structured methodology for assessing IAQ, including:
​​

1. Determining IAQ Goals

We begin by setting specific objectives for the assessment, identifying pollutants of concern, and establishing air quality targets based on WELL, LEED, ASHRAE, and Alberta Infrastructure guidelines. Check out our blog post that discusses the differences and benefits of WELL, LEED, ASHRAE, and the Alberta Infrastructure Guidelines.
​

2. Conducting Site Assessments

Our team performs thorough site evaluations to identify potential sources of indoor air pollution and assess the building's ventilation system. This includes visual inspections, air sampling, and testing for key parameters such as:
  • Particulate Matter (PM2.5, PM10)
  • Volatile Organic Compounds (VOCs)
  • Carbon Dioxide (CO2)
  • Carbon Monoxide (CO)
  • Mould
  • Formaldehyde
  • Radon
​The WHS IAQ Response Process, which includes a multi-level investigation approach:
  • Level 1: Walkthrough survey and qualitative assessment.
  • Level 2: Testing for comfort factors using calibrated equipment.
  • Level 3: Involvement of technical professionals for complex issues.
​

3. Data Analysis

We analyze collected data to pinpoint pollution sources and evaluate ventilation effectiveness. Our analysis is compared with established IAQ goals from WELL, LEED, ASHRAE, and Alberta Infrastructure standards to ensure compliance.
​

4. Developing a Plan

Based on our analysis, we create a tailored plan to address identified IAQ issues. This includes recommendations for improving ventilation, controlling pollution sources, and implementing air cleaning devices.
​

5. Implementation and Evaluation

We implement the plan and conduct ongoing evaluations to ensure sustained IAQ improvements. Our team uses continuous monitoring and testing, adhering to WELL and ASHRAE protocols, to maintain optimal air quality.
