The deadlock

Owners want to save, they just cannot agree how

Every energy project in a condominium needs a vote at the general assembly, and each owner weighs it differently, so a profitable, well-financed project can stall for years without a single number that speaks to each of them

Ground floor

No gain from the works

Sees little benefit from an elevator upgrade or shared systems higher up the building

"Why would I pay for that"
Top-floor studio

Fears a bigger bill

Worries the cost split will land unfairly and push monthly charges up out of proportion

"My charges will jump"
Landlord

Never sees the meter

Does not pay the energy bill directly, so the saving feels abstract and easy to postpone

"It is not my bill"
Outcome

The vote fails, and the building keeps overpaying

The shift

We make the invisible visible

Synerwatt turns raw consumption into one clear figure per apartment, personal savings, your share of the cost, and the payback in years, when everyone sees their own gain, agreement follows

  • Savings in euros, never abstract percentages, for every owner
  • AI forecasting that shifts load to off-peak hours and flags waste
  • Fair cost distribution based on real usage, not just ownership shares

How it works inside

Three modules, one continuous loop

Data comes in, intelligence turns it into decisions, and every result feeds the next forecast

01 · Sense

Monitoring and data

Reads Linky smart-meter data every 30 minutes, then adds IoT sensors and building systems into one live picture

  • 48 data points a day per apartment
  • Portfolio view for the syndic, personal view for the owner
  • 24 months of history at your fingertips
02 · Think

AI optimization

Forecasts consumption, shifts load to cheaper off-peak hours, spots leaks and anomalies, and predicts solar output

  • Weather-adjusted forecasts, target accuracy under 15% error
  • Automatic anomaly and leak detection
  • Load shifting across off-peak and peak tariffs
03 · Decide

Decision support

Builds each owner's savings case, runs investment scenarios, generates the assembly report, and splits costs fairly

  • Personalised savings and payback for every apartment
  • Ready-to-present PDF reports for the general assembly
  • Subsidy eligibility flagged where it applies
Every decision improves the next forecast

Why now

Five forces pushing condominiums to act

The pressure is regulatory, financial and technical at once, and it is building this decade

Force 01
+50%

Tariffs on the rise

Regulated electricity prices climbed more than half since 2021, and the long trend still points up

Force 02
2028

Class G rental ban

The least efficient buildings can no longer be rented out, which turns renovation into a legal must

Force 03
75%

Subsidies available

National programmes cover up to three quarters of renovation costs for eligible condominiums

Force 04
95%

Smart meters live

The Linky rollout is complete, so the data layer is in place with nothing left to install

Force 05
Solar

Shared generation grows

Collective self-consumption is spreading, and it needs the metering and allocation we provide
