One platform for the entire heating operation in existing buildings

Analyze portfolio

From data acquisition to portfolio assessment: ECCO2 combines sensor technology, AI control and a Swiss data platform into one system — installed in days, effective from the first heating season.

Solution · How ECCO2 works

The black box building becomes a controlled asset with measurable performances and an immediate impact.

ECCO2 Building Intelligence regulates the heating operation of existing buildings on a data basis — in four steps, as a continuous cycle. This sequence creates concrete effects across the entire portfolio: less energy and CO₂, lower costs and verifiable evidence. Without a new heating system, without structural work, from the first heating season.

How the solution works — in four steps

01Measure

Sensors in apartments record temperature and humidity, meters record real consumption continuously and during operation. The wireless sensors transmit via LoRaWAN, without Wi-Fi or cabling. This brings visibility for the first time into how a building actually behaves during the heating season.

100 % transparency per building, in real time.

02Understand — NARA AI

NARA connects the live data with the local weather forecast and builds a digital twin from the thermal behavior of each building. This allows the system to anticipate the necessary actions: if sunshine is forecast, it reduces the heat supply before the apartment overheats.

Self-learning per property, continuously optimized.

03Control

A gateway connected to the existing heating system continuously sets the optimal flow temperature — exactly as much heat as the building needs. The system is not replaced; the adjustments are fractions of a degree over hours and are not noticeable to the tenants.

Impact immediately, without loss of comfort.

04Verify

The savings are calculated with weather adjustment — using a FOEN-audited methodology. Calculated promises become verifiable results, directly usable for reporting.

Verifiable, certified, exportable.

What this achieves

Lower operating costs

Because the building only heats as much as it needs, heating energy consumption falls by an average of 20 %. This lowers tenants’ ancillary costs and helps finance further measures.

on average 20 % less heating energy & CO₂

Evidenced CO₂ pathway

The reduction is measured, not only calculated — Scope 1/2 emissions fall demonstrably. The reduction pathway becomes real, not just in the energy certificate.

measured instead of modeled

Controllable portfolio

A consistent data basis shows which properties carry the greatest potential and where CAPEX really has an effect — a basis for investment planning and value retention.

CAPEX where it counts

ESG reporting at the push of a button

Hard operating data per building and portfolio flows directly into reporting — from your own operational reality, not from external estimates. Data hosted in Switzerland and available in your hands at any time.

verifiable, FOEN-audited

Relieved operations

Via the Caretaker App, caretakers see the condition of every property in real time and act in a targeted way — comfort problems are identified before tenants call.

higher service quality towards tenants

Better investment decisions

When replacing a heating system, the measured demand shows the right system size — correctly dimensioned instead of oversized. The margin required by the standard remains, third-party buffers are eliminated.

fewer misinvestments

FAQ

Frequently asked questions.

Yes. ECCO2 regulates the operation of the existing heating system via sensor technology and AI — no structural work, no new heating system. A gateway is connected to the existing controller. The effect is measurable from the first heating season.

Nothing is transformed — the heating system stays as it is and is simply controlled intelligently. The sensors’ installation requires brief, announced access to the apartments; installation takes a few minutes per apartment, wireless, without Wi-Fi and without cabling. After that, everything runs in the background.

You do. The data is hosted securely in Switzerland and remains in your hands — exportable at any time, as a basis for your ESG reporting and your portfolio strategy. In the apartments, only indoor climate data (temperature, humidity) is recorded, no personal data; transmission is end-to-end encrypted and the data is anonymized at source.

No. ECCO2 specifically regulates the heating — the flow temperature — in parallel with the existing system. We replace neither your heating system nor your building automation and do not take over the entire building technology.

Via the FOEN-audited methodology, considering weather conditions, and an annual verification. This means a mild winter cannot fake savings — and a harsh one cannot hide them.

ECCO2 is a subscription per heated square meter and its operation finances itself from the savings

Installation takes hours per building, the impact is measurable from the first heating season. The usual path: portfolio analysis, relevant scope pilot, rollout after demonstrated success.

For every heating system and every energy source — the solution builds on the existing system.
