Step 1: Prepare measurement equipment and sensors
When analyzing indoor climate data effectively, preparing your measurement equipment and sensors is crucial for reliable results. You need to ensure that all equipment is properly calibrated, clean, and functional before data collection begins.
Before you start measuring, we recommend reviewing and testing all your sensors. Choose reliable indoor climate measurement devices that can measure key parameters such as CO2 levels, humidity, temperature and air quality. Check battery levels, clean sensor surfaces and verify their accuracy by comparing with certified reference instruments. Place sensors strategically in different zones of the room where people spend the most time to get representative measurements.
Pay special attention to placement and calibration. Avoid direct sunlight, ventilation outlets or areas with extreme temperature fluctuations as these can distort your measurement results. A rule of thumb is to place sensors at human breathing height and at least one meter away from walls or large furniture to ensure reliable data.
Once the equipment is prepared, you are ready for the next phase of your indoor climate data analysis.
Step 2: Collect relevant indoor climate data
When you are ready to collect indoor climate data, it is crucial to focus on accurate and relevant measurements. Your data collection strategy should be systematic and targeted to ensure high data quality and actionable insights.
Choosing the right IoT sensors is crucial for successful data collection. Identify the key parameters you want to measure, such as temperature, humidity, CO2 levels, noise, and air quality. Place sensors strategically in different zones with varying levels of activity and perform ongoing calibration to ensure accuracy.
Remember to define a clear purpose for the data collection. Data collection should be focused and specific to the specific indoor climate challenges you want to address. Be aware that different spaces and activities may require different measurement strategies.
After data collection is complete, you are ready for the next phase: thorough analysis of the collected data.
Step 3: Organize and structure data for analysis
Once you have collected your indoor climate data, the next critical step is to organize and structure this data in a systematic and understandable way. A well-prepared data structure is essential for conducting an effective and reliable analysis.
Start by gathering all your data sets into a central system or spreadsheet. Use data from the CLOUD as a guide to action , helping you categorize your measurements by parameters such as temperature, humidity, CO2 levels and noise intensity. Create clear columns for each measurement unit, date, time and location so you can easily compare and analyze the data.

Be careful to clean up your data set. Remove inaccurate or noisy measurements and mark any unusual data points for further investigation. Group your data by relevant categories such as room type, activity level or time period to create a more nuanced picture of indoor climate conditions.
Once your data is organized, you are ready for the next phase: the actual data analysis, where you will extract valuable insights about the quality of the indoor climate.
Step 4: Analyze trends and identify problem areas
Once you have organized your indoor climate data, the next important step is to analyze trends and identify potential problem areas. This phase is about transforming raw data into actionable knowledge that can improve indoor climate.
Use statistical analysis tools to identify patterns and anomalies in your data sets. Investigate challenges with school indoor climate by comparing measurement results over different time periods and locations. Look for recurring patterns in temperature, humidity, CO2 levels, and noise intensity that may indicate systematic problems.
Pay particular attention to extreme values or sudden changes that may signal specific indoor climate challenges. Identify critical times and zones of persistent poor measurement results. These data points may reveal the need for immediate intervention or long-term improvements in ventilation, temperature control or air quality.
Once you have identified trends and problem areas, you are ready to plan specific improvement measures for the indoor climate.
Step 5: Verify results and document efforts
After analyzing your indoor climate data, the next critical phase is to verify the results and document your efforts. This process ensures data quality and creates a solid foundation for further action.
Documentation is essential to improving indoor climate through systematic review and validation of your collected data. Compare your results with previous measurements, recommended standards and possibly benchmark data from similar buildings or rooms. Pay particular attention to statistically significant deviations and repeat critical measurements if necessary to confirm their accuracy.
Create a thorough report that includes graphical representations, tabular overviews, and concrete recommendations. Don't just document the raw data, interpret it meaningfully. Highlight specific problem areas, potential causes of indoor climate challenges, and suggest concrete improvement initiatives.

Once the results have been verified and documented, you are ready to implement targeted improvements to the indoor climate.
