Quickscan COVID-19 and ventilation in offices

Technical service providers can determine together with building managers whether the ventilation in office buildings are satisfactory. They can do this with the quickscan COVID-19. It will also show what they can do to improve this.

This scan mainly makes it possible to determine the quality of air exchange and ventilation systems in an office building.

Indication of chances of infection

The scan is based on the existing guidelines, (building) regulations and professional publications. The resource also refers to recommendations prepared by REHVA; the European umbrella organization for ventilation and air treatment. The tool consists of two parts: part 1 consists of a step-by-step plan for inspection offices to collect data with which the quality of air exchange and ventilation systems can be determined. In part 2, the ventilation quality is shown on the basis of data collected from an accompanying Excel spreadsheet.


The scan converts the ventilation quality to the CO2 concentration per room. Since the CO2 concentration is only one of the indicators of the ventilation quality, more components must be tested in the scan.

Whoever applies the scan determines or checks the following steps:

1. The type of the ventilation system present per room;

2. The ventilation quantity per room;

3. The number of people per room;

4. The ventilation quality per room (with the Excel spreadsheet);

5. The possible space occupation with the ventilation quality;

6. The question of whether guidelines and recommendations from the government and REHVA have been followed.

This tool has been drawn up for experts who are familiar with ventilation installations and related guidelines, such as installers, consultants and employees of technical services and facility organizations. The scan is available via the website
