This is the share of heating in the carbon emissions of buildings in operation. With its innovative low carbon heating and cooling technology, Accenta takes you a giant step towards drastically decarbonizing your buildings.

How does the system work?

The environmental transition of buildings requires efficient and low-carbon energy systems. Accenta's low carbon heating and air conditioning concept was born on this insight, after 3 years of R&D in partnership with laboratories from Ecole Polytechnique, Ecole des Mines de Paris and BRGM.

Collection of solar energy and waste heat

In the middle of summer, when air conditioners are running at full capacity, our energy system recovers the waste heat usually lost from the air conditioning processes in your buildings. When there is no AC, renewable heat can also be produced using low-temperature solar thermal panels or coupled with photovoltaic panels and heat pumps.
Thermal storage for large scale use of renewables

During summer, the renewable heat is injected into a geothermal storage facility. This is a field of geothermal probes up to 200m deep. A fluid circulates through it, exchanging calories with the underground, which acts like a real battery. This heat is stored for several months to meet the energy needs of the building in winter.

Support throughout the life of your projects

Accenta's technologies are used to design and guarantee the operating performance of the low carbon heating system adapted to the needs of your buildings. A network of partners and ESCOs ensures the turnkey implementation and operation of the system. The whole system comes together with an energy performance contract to secure the carbon and economic performance.

How do algorithms guarantee carbon performance?

The Artificial Intelligence algorithms of the .PILOT LowCarbon service optimize the control of your system to achieve the best possible performance in all conditions.

Anticipation of the needs of your building

AI takes into account the theoretical and real behavior of your building to predict its needs several days in advance depending on the weather.

It is not just an other geothermal system

We optimize the whole system

A geothermal system has various components. Rather than optimizing one part at the expense of the others, we optimize the whole. And that changes everything.
We consider the ground as a battery
We use AI to make a difference

Thanks to AI we optimize the sizing of the system to reduce its cost and anticipate environmental conditions rather than suffer them to maximize performance. The software aspect thus becomes a central element of the geothermal system and gives it scalable capabilities that did not exist before.

From buildings to low carbon districts

Thanks to the intelligence of its algorithms, Accenta is democratizing Thermal Smart Grids for eco-districts. It is an intelligent network that enables the production of heat and air conditioning to be shared between several buildings.

Suitable for high performance buildings

Accenta's technology works with a low-temperature (< 30°C) tempered water loop that is particularly suitable for high energy performance buildings.
Takes into account the real needs of buildings
Maximizes the shared use of renewables

The possibility of exploiting geothermal, solar or waste energy from air-conditioning processes depends on specific characteristics that are not shared by all buildings. With an Accenta Thermal Smart Grid, you have more freedom to maximize the use of renewables for an entire district.
Eliminates heat islands

What it does for you

1. Record and profitable decarbonation

Rather than accumulating expensive solutions, Accenta offers you the highest and most cost-effective level of decarbonation through a single, perfectly optimized system.
2. You are protected by an Energy Performance Contract
