With INDALO®, first indoor air quality simulation software, you make the right choices of materials and ventilation strategy to ensure quality air for future occupants. You validate the actions that have been implemented.

With INDALO-COVID, you can even verify that the actions currently in place are sufficient to limit the spread of the coronavirus in your customers’ buildings. Help them in their decisions by suggesting other ways to implement or a better ventilation strategy to stop contamination.

With INDALO Supervision, which you can offer to your customers as a white label solution, guarantee good air quality in the buildings operated at all times! This predictive tool anticipates pollution peaks and avoids them by intelligently controlling ventilation.

You are a local authority?

Secure your air quality objectives from the design phase

Octopus Lab supports you to ensure better air quality in your establishments.

Thanks to our exclusive simulation tools, we are able to assess indoor air quality even before your establishment is built or renovated. We can thus guide you in the right choices of materials and ventilation systems to guarantee quality air for future users.

No more unpleasant surprises: the regulatory pollutant threshold values ​​will be respected and everyone will be able to benefit from healthy air.

Guarantee healthy air at all times in your establishments

INDALO Supervision is a software solution that can be deployed in your schools, your nurseries and in all other public buildings to ensure good air quality for the occupants. It is based on measuring devices from our partner Ethera. These allow precise monitoring of formaldehyde and other regulatory pollutants.

INDALO Supervision allows you to monitor the air quality of your building stock, to have a centralized air quality management (archiving of measurements and self-generated expert reports) and to be alerted in the event of a forecast of exceeding or proven exceeding of the regulatory values.

INDALO Supervision can even send piloting instructions to your air handling units based on its indoor air quality predictions. Thus, the system prevents users from breathing stale air and thus preserves everyone’s health.

Limit the risk of the coronavirus spreading in your buildings

We carry out studies to estimate the risk of the spread of Covid in buildings. Thus, we provide you with decision support to implement the best ventilation strategy and the means necessary to limit the risk of contamination.

You are a facility manager / a real estate services company / an energy and sustainability expert?

What if you offered good air quality to your customers? Differentiate yourself by including INDALO Supervision, a unique and innovative solution, in your global offers!

Distribute INDALO Supervision as a white label solution or integrate it via the API into your existing building management systems.

This indoor air quality modelling software service anticipates periods of pollution and sends ventilation control instructions, while maintaining the energy performances of your buildings.

Think about air quality from the design phase

Adopt a consistent approach by making the right construction choices to guarantee good air quality in your future structure. Our team of digital simulation and indoor air quality (IAQ) experts supports you in your choices of ventilation and materials.

What about the Covid?

We carry out studies to estimate the risk of the coronavirus spread in your buildings. Make sure your existing or future real estate portfolio is well suited to tackling the Covid spread. We provide you with decision-making support to implement means to limit the risks of contamination (better ventilation strategy, limitation of the number of people per space, etc.).

You are a ventilation or materials manufacturer?

Do you want to add more value to your products by demonstrating their effectiveness in ensuring good air quality or low emissivity and highlighting this competitive advantage? Do you have an R&D project requiring air quality expertise?

We put our expertise in indoor air quality and simulation at your service!

If you want to be autonomous and carry out your own air quality studies yourself, use INDALO®, unique and innovative software.

How about listing your products in INDALO®?

Integrate your products free of charge into the database of our INDALO® indoor air quality simulation software, the only one on the market. This influences the choices of builders and thus places itself as a prescriber of materials and ventilation.

You thus highlight your virtuous products for air quality and gain visibility. We offer our users a wide choice of references. A winning partnership!

They trust us. What about you?

You are a real estate developer?

As air pollution has become a major public health problem, the population is showing increasing interest in the indoor air quality of their home. 

This is why we suggest you differentiate yourself by offering to preserve the health of your future occupants! We support you in your procedures from the competition phase to ensure better air quality for your operations. By using exclusive simulation tools, our team of experts meets your needs and concerns: what is the impact of outdoor pollution on the indoor air quality (IAQ) of my future building? is a double flow ventilation system necessary? … We help you to make the right compromise between air quality and cost.

You have another activity?

Our team is made up of experts in indoor air quality (IAQ) and IT development, so we can meet all your needs in terms of IAQ software solutions.

Do you have a specific pollutant whose concentrations you want to monitor and predict in order to anticipate your actions? The sector in which you work was not mentioned on our website but would require our intervention?

 During the MERMAID research project on indoor air in low consumption buildings, during which INDALO was designed, we observed that the software’s forecasts were comparable to the actual measurements. So this is a serious solution that has a bright future. Buildings are more and more airtight, so owners must understand that the additional cost generated by the attention paid to air quality will quickly be absorbed by savings on future repairs, especially in terms of ventilation.
