Wattflow – Smart Energy Management for Office Buildings Buildings

We don't talk a lot of hot air,
But we talk a lot of hot air.

Extreme climate variability and stricter energy regulations drive the need for smarter management systems. With heating, ventilation, and air conditioning accounting for over 70% of energy consumption in office buildings, Wattflow builds cutting-edge IoT and AI to natively interconnect HVAC machines.

Using energy waste,

to deliver comfort.

What's the matter?

On one hand. Chaos.

With a part of 43%*, buildings (already) are the largest consumer of energy
In office buildings, HVAC systems account for over 70% of this consumption. A diverse and opaque offer of equipments (air handling units, heat pumps, direct expansion systems, radiant heating…) whose operation is never truly coordinated

*French Ministry of Ecological Transition, 2024

On the other hand. You.

Owners and operators of commercial buildings are already under constant pressure to reduce their buildings' energy consumption, whether it is for economic or regulatory reasons*, while ensuring the highest level of comfort for their users.

*Tertiary & BACS Decree

On the other (other) hand. Nothing and no one to help.

Today traditional Building Management Systems (BMS) can only (partially) solve this problem in very large buildings, using outdated automation technologies that are complex to operate and (very) expensive to implement, and do not take into account all the parameters impacting your energy consumption..

So?

We eliminate your need for complex-&-costly-to-install-&-maintain-&-understand-&-see (because they are on the roof, sorry) systems with a pragmatic, intelligent and connected solution that makes your office buildings truly...

Sustainable

Comfortable

Compliant

Is Wattflow a Cloud BMS?

A bit of everything,
so whatever label pleases you.

How do we do?

With our team and help of european research laboratories, we developed our own end-to-end technology to answer your needs. No plugs from a bench of diverse companies and manufacturers. No one required on your end to operate it. Smooth operation, cost control, and independance.

3 simple jobs, from signals, to data, to comfort.

We collect and measure your data.

We add sensors in strategic locations of your buildings, and connect our Wattflow Box and all HVAC equipments to your Wi-Fi/Ethernet network to collect and analyze over 200 real-time data points every minute.

PATENT PENDING 🤫

We discuss with your machines.

Our Wattflow gateway (which we keep secret) is compatible with all types of machines, brands, and all standard manufacturer communication protocols.

We stop them doing silly things.

We optimize their functioning.

Sorry.

Using AI-based prediction systems trained from our guidelines on thermal comfort and efficiency, and energy optimisation logic.

Wattflow is certified as a Deeptech company since 2025 by the French Tech Emergence of BPI France

Is it interesting if I already have a BMS?

Yes, our solution complements existing BMS by adding intelligence for more precise and automated management. A traditional building management system is often limited to supervision, whereas we provide active and continuous optimisation.

What if I don't have any BMS?

Don’t worry, we got your back.

What the f* is BMS again???

We’ve been there. Don’t worry, got your back too.

Your wishes, our commands

So that your summers at the office feel like this,

your winters like this,

without ever tapping on that again.

Your questions, our focus.

I have and am accustomed to a traditional building management system and the investment has already cost me a lot. Can Wattflow really bring me more?

Your current system works, but is it optimised? Our solution complements existing building management systems by adding intelligence for more precise and automated management. . A traditional building management system is often limited to supervision, whereas we provide active and continuous optimisation, collecting and analyzing data that are not taken into consideration yet (weather, inertia, energy prices, real time CO2 emissions…). Our customers have often found that they can reduce their energy bills and improve comfort without major work. Plus, our solution connects to existing infrastructure without requiring any large initial investments.

How do you guarantee energy and bill savings?

Easy peasy, we shut down your entire system, deny you access to your remote controls, and recommend a list of shops where you can buy warm jumpers for the winter. Otherwise, as your comfort is still our priority, and without compromise, we guarantee a reduction in your consumption thanks to our secret recipe that directly coordinates your HVAC equipment and adjusts its operation for you based on all the data we collect. Plus, we always offer a pre-installation audit and performance monitoring to guarantee results.

Does the Wattflow solution require management and skills on my part?

Installation takes just a few days and won't disrupt your daily routine. Our interface is designed to be intuitive and requires no extensive training. However, we are committed to helping you understand your own equipment and optimise its operation.

What is the price of your solution?

The price of the solution is calculated based on your property portfolio (number of buildings, size) and your equipment (number of items and number of different machine brands). The quote is then divided into two parts: reduced commissioning costs thanks to Energy Saving Certificates (ESC), and a subscription model that is very often covered by the savings generated. Our customers see a return on investment in less than a year, with long-term financial gains.

Why did you choose to connect your solution to a Wi-Fi/Ethernet network ? I'm afraid mine won't support it.

Wattflow uses the network you already have so installation is plug-and-play, fast, and low-cost. Our edge box sends only secure, outbound traffic to our cloud-based applications.
What this means for you :

Works on standard office networks (Ethernet preferred; Wi-Fi 6 (2.4 & 5Ghz supported).
Low bandwidth telemetry; no inbound ports to open.
Easy to isolate on a dedicated VLAN/guest network if desired.
Resilient: buffers locally and resyncs after any outage.

If your network is highly constrained, we’ll assess options with your IT.

And don't worry, at the end,

you can always decide not to choose us.
