the back story
The concentration of CO2 in the atmosphere, currently 420ppm, is rising. This will have profound effects on the habitability of our planet and poses an existential threat.
Your home represents up to a quarter of your personal carbon footprint. Reducing this is critical to keeping global CO2 levels under control.

How It all got started
Increasing the air tightness of a house is one of the most cost effective methods of improving energy efficiency, particularly in very old homes. However, with increasing air tightness comes raised risks to health and the property itself. Even in big cities with heavy traffic, indoor air is often even more polluted than outdoor air.
The majority of homes do not have a deliberate ventilation strategy. While heating controls and thermostats are ubiquitous, Air Quality Monitors are very rare, even in properties with advanced ventilation systems (such as MVHR).
Just as it is impossible to tell the temperature of a home without a thermometer (or control temperature without a thermostat), it’s impossible to tell if ventilation is adequate/excessive without a decent air quality monitor.
I therefore came up with the idea of an air quality monitor that the occupier could refer to, to assess ventilation , and a ventilation system that would be directly controlled by the same air quality monitor.
Our core mission
Our main goal is to raise awareness of indoor air quality.
My belief is that air quality monitors should be standard in all homes, and so should a ventilation strategy.
- air quality monitoring in all homes
- a deliberate ventilation strategy in all homes
- improved air tightness
- healthier homes
