Feeling good in your home? Three indicators to keep an eye on.

What is the right indoor temperature for my home?

The ideal temperature for your home depends both on the rooms you live in and the habits of the occupants.

In the main rooms, such as the living room or kitchen, the recommended temperature is 19°C. Those who are less fussy will reduce the temperature to 17°C, while others will prefer 20°C. On the Compte CO2 application, using your price-comfort indicator, you can test the impact of plus or minus one degree in the house on your bills!

In sleeping rooms, you can lower the temperature to 16°C or even 15°C.

You can also decide to renovate your home to reduce your energy bill while maintaining a comfortable indoor temperature. In most countries you will benefit from government subsidies such as Ma Prime Renov scheme in France for example.

What is the correct humidity level inside my home? 

Air quality in the home also depends on the humidity level in the air. When it rains, the humidity level is close to 100%, which is not the most comfortable.

Generally speaking, when the humidity level, also known as hygrometry, exceeds 70%, the house is prone to dust mites and mould. These are not the best conditions for air quality in the home.

On the other hand, air that is too dry, at around 10% humidity, is not comfortable either. Static electricity phenomena abound. This can even lead to respiratory problems or irritation of the airways.

For optimum air quality in the home, aim for between 40% and 60% humidity.

What is the right level of CO2 inside my home?

The quality of the air in your home also depends on the CO2 concentration in the air.

This concentration of CO2, expressed in parts per million or ppm, has an impact on the human body.

A CO2 concentration inside the home of between 350 and 450 ppm corresponds to a healthy environment. A simple mnemonic to remind you that it is also below this 450 ppm threshold that we will be limiting the rise in global surface temperature to below 2°C! At home, as in the fight against climate change, let's not exceed 450 ppm! In fact, that's the name of the company behind the Compte CO2 project!

At the other end of the scale, with concentrations above 1,000 ppm, people start to experience symptoms such as drowsiness. The longer a person is exposed to high concentrations of CO2, the greater the risk of serious symptoms.

The CO2 Acount application gives you the concentration of CO2 inside your home, and uses the table below to display in a green colour when the air is healthy, or a red colour if the air is stale.

To find out more about these issues and how to control indoor air quality, we recommend that you read the opinions of leading authority on the subject of your country such as Haut Conseil de la Santé Publique in France or UK Health Security Agency in the uk
