Step-by-step measurement of air quality in institutions

Up to 90 percent of our time is spent indoors, and therefore the air quality in institutions has a great impact on both well-being and health. Poor indoor climate can lead to headaches, difficulty concentrating, and increased absenteeism among children and employees. Here you get concrete steps on how to systematically measure and improve air quality in Danish institutions, so everyone gets a healthier and more comfortable environment.

Quick Summary

Step 1: Select relevant air quality parameters

When measuring air quality in institutions, it is crucial to choose the most relevant parameters. The importance of air quality begins by identifying the specific factors that affect the indoor climate.

The primary air quality parameters you should focus on include CO2 levels, humidity, temperature, particle concentration, and chemical compounds (TVOC). Each parameter provides unique insights into the health properties of the air. CO2, for example, indicates ventilation efficiency, while TVOC measures the presence of volatile organic compounds that can originate from building materials, furniture, or cleaning products.

Choose measuring instruments that can record multiple parameters simultaneously to obtain a complete picture of air quality. Digital sensors provide real-time data and enable quick response to unwanted changes. Air purifiers can supplement these measurements by actively improving air quality.

Pro tip: Consult local health authorities to ensure that your chosen parameters match the latest recommendations for institutional indoor climate standards.

Here is an overview of the most important air quality parameters and their significance in institutions:

Step 2: Prepare the room and place measurement equipment correctly

Preparation and correct placement of measurement equipment are crucial for accurate air quality measurements. This phase is about creating the right conditions for reliable data collection in institutional environments.

Air measurements require strategic placement of sensors away from direct heat sources, ventilation openings, and strong direct sunlight. Choose central positions that represent the general air conditions of the room. Place sensors at breathing height (typically between 1.2 and 1.5 meters from the floor) to capture the most relevant air quality data.

Avoid placing measurement equipment near windows, doors, or other airflow areas, as these can distort the results. Ensure at least 50 centimeters distance to walls and furniture to ensure free air circulation around the sensors. Air quality in classrooms varies significantly depending on placement, so be careful with your setup.

Pro tip: Make a sketch of the room and mark the precise locations of your sensors before the actual installation to ensure optimal data collection.

Step 3: Calibrate sensors for accurate measurements

Sensor calibration is a critical process that ensures reliable and accurate air quality measurements in institutional environments. This phase is about adjusting measurement equipment to provide the most precise and trustworthy results.

Indoor climate indicators require high precision during calibration. Start by checking the sensors' baseline by placing them in a neutral environment with known air quality. Always follow the manufacturer's specific guidelines for calibration. This often involves adjusting sensor sensitivity and comparing with reference measurements from certified instruments.

Perform calibration under stable environmental conditions without extreme temperature or humidity conditions. Repeat calibration at regular intervals to ensure ongoing accuracy. Document each calibration cycle with date, results, and any adjustments to maintain traceability and data quality.

Pro tip: Always keep a calibration certificate and log of sensor adjustments to document the reliability of the measurements and support any future quality controls.

Step 4: Conduct measurements and record data

Conducting air quality measurements is a systematic process that requires careful attention and precision. This phase is about collecting accurate data that provides a clear picture of the indoor climate conditions.

Use data from the sensors as a guide to action by following a structured data recording method. Start by activating all sensors simultaneously and ensure continuous data collection over a defined period. Document environmental conditions such as temperature, humidity, and activity level in the room parallel to the measurements to provide context for the collected data.

Be aware of any fluctuations or anomalies during the measurement process. Record data in a digital format with clear time indication and sensor placement. Store raw data and initial analyses in a secure and easily accessible system that allows for subsequent detailed review and comparison.

Pro tip: Create a standardized data recording protocol with clear guidelines for measurement interval, data format, and storage methods to ensure consistency and comparability between different measurements.

Step 5: Evaluate results and adjust efforts

Documentation of air quality measurements requires a systematic and critical review of the collected data. This phase is about translating measurement results into concrete actions that improve the indoor climate in the institution.

Analyze data fluctuations by comparing measurement results with recommended standard values for various air quality parameters. Identify patterns and critical points such as high CO2 levels, inappropriate humidity, or the presence of harmful chemical compounds. Assess whether the problems are temporary or persistent and prioritize adjustment efforts accordingly.

Select specific intervention strategies based on the data analysis. This may include improved ventilation, adjustment of heating and cooling systems, implementation of air purifiers, or changes in building operation. Implementation of indoor climate policy should be done gradually with continuous follow-up and evaluation.

Pro tip: Establish a continuous monitoring system where you systematically record changes and their effect on air quality to always be able to document and improve your efforts.
