Vertical ventilation!

Better academic performance and enjoyment through a safe and healthy indoor climate.

Average CO2 value in a Goflow ventilated classroom

0 ppm

Why vertical ventilation?

During the corona pandemic, we found that traditional ventilation systems were not sufficiently capable of reducing aerosol exposure in students. Research from TNO in 2021 has shown that the vertical displacement ventilation system developed by Goflow reduces aerosol exposure by 97%.

Here's why!

First conclusions and observations:

  • The average gas consumption decreases from approximately 10 m³ to approximately 4 m³ of natural gas per m² GFA (gross floor area) without any modifications to the building's envelope.
  • Average CO2 levels during classroom hours remain below the promised 700 ppm.
  • Average particulate matter concentrations also remain below the promised 3 µg/m³.
  • A Goflow floor is always cleaner than a traditional floor.

How does the system work?


Vertical displacement ventilation carries air by the most direct route to the outside without contact with other occupants in the room.


In a Goflow classroom, it feels like you are being educated in open air. Every child and every teacher deserves that feeling, every day.

What are the benefits?


Goflow's climate system is at least 70% more energy efficient than current systems. Instead of radiators, Goflow uses convectors under the floor that heat or cool the air, provided a heat pump is used.

Best for health

TNO research shows that students in a Goflow classroom are exposed to 97% less aerosols. A healthy indoor climate leads to better learning performance and lower absenteeism. Initial feedback from the occupational health and safety service, show a 90% lower short-term sick leave among teachers.

Sustainable & socially responsible
Goflow aims to develop the most sustainable system possible, designed for intensive long-term use. Goflow primarily applies the principles of Design for Disassembly and Design for Reuse. Additionally, Goflow strives to create social impact. For instance, Goflow has collaborated with the social workplace DZB Leiden and partners with the municipality to provide roles for refugees.

De CO2-waarde in een Goflow-klaslokaal komt niet boven de 700 ppm. Dat is ver onder de ‘Frisse Scholen klasse A’-norm. Geniet de hele dag door van optimale comfort voor een beter concentratievermogen.
