The problem

The solution

There are about 1700 certified ventilation inspectors in Sweden, today many of the
inspectors work analogously.


We have understood that inspections often are performed with the help of a computer, paper and pencil. It is common for the inspector to take these tools to the building where the inspection is performed. The inspection report is written, printed and signed at the office. 

This results in long administrative processes and rewriting and printing of physical protocols. 

Approvent today digitalizes the process of creating, signing and sending inspection protocols, specifically for ventilation inspections.

The app's functions and design are developed together with inspectors in the industry, the app is thus specifically developed for inspectors to have an efficient and easy-to-use digital work tool for performing inspections.


The goal is for the inspector to save time and avoid administration.

Overview of the inspection

The app is designed for a logical workflow.
It should be easy to log information when you are working in different environments.

we take care of the calculations

Thanks to mathematical formulas adapted to your specific tasks,
we can make your job easier and faster.

Digital signing, of course

Stop printing paper,
sign digitally directly on the screen.

More about ventilation inspections

In Sweden, it is statutory for properties to undergo a ventilation inspection every 3 or 6 years. The purpose of the inspection is to improve the indoor climate and check that the ventilation system works satisfactorily.

People who have the certification are experts and inspect ventilation systems on a daily basis. The inspectors create and sign inspection protocols with an accompanying certificate which is proof that the inspection has been performed with an approved grade.
