ECCO2 makes heating more intelligent: AI-optimized heating energy with an average efficiency gain of 20 % – without structural work, with lower operating costs and a transparent CO₂ pathway.

Starting position

The energy transition is decided in the building.

Almost half of Switzerland’s final energy goes into buildings — most of it into heating.

The challenge

What nobody measures is systematically run too high.

What is not measured cannot be controlled according to demand and is, in practice, often overrun. Today, many buildings are heated “to the standard” instead of to real demand: planning assumptions, safety margins and old parameters remain in the system and drive consumption above the effective heat demand. ECCO2 reverses this mechanism: we measure real operation, learn building and climate behavior, and control the heating dynamically accordingly. This means heating finally follows “demand” instead of just “the standard” – logically efficient and superior to planning.

The leverBuildings constantly run above their actual demand.

Systematic overheating

Heating systems are set once at commissioning – with generous reserves for flow temperature, flow rate and operating times. The result is systematic overheating: surplus energy that increases tenants’ ancillary costs and raises the owner’s CO₂ emissions.

Missed CO₂ targets become a value risk

Anyone who does not achieve the reduction pathway pays with higher levies, more expensive financing and stranding in the portfolio. The effect lies not in the energy certificate, but in measured operational performance.

Operational excellence

Model values, energy certificates and monitoring tools show numbers, but they prove nothing. What is required are results from operation. That is exactly what ECCO2 delivers: as the Swiss market leader, with mature processes, technology and references. Portfolios are managed efficiently and continuously optimized — building by building, fully automated.

The blind spot

Normative calculations end with planning. Operation is often left to itself.

The lever

Intelligent, data-based heating optimization turns theory into reality – and typically reduces energy consumption by +20 %, immediately and without structural work.

Our solution

ECCO2 Building Intelligence – heating operation, professionally optimized.

Our AI-based solution measurably reduces heating energy consumption and CO₂ emissions in existing buildings from the first heating season – without a new heating system.

01Measure

You understand how your buildings actually react to heating in real world conditions.

ECCO2 continuously records heating energy, indoor climate and operating behavior and makes the data available in structured form at building and portfolio level. This creates a robust basis for technical optimization, decarbonization pathways and ESG reporting.

100 %transparency per building
02Optimize

Your heating operation is continuously controlled instead of statically set.

Based on the measured data, our AI continuously optimizes heating operation – taking weather, building behavior and use into account. As a rule, customers thereby achieve 20 % less heating energy consumption and CO₂ emissions, with unchanged user comfort.

20 %less energy & CO₂
03Steer

You can report savings and impact in a comprehensible way.

The savings achieved are determined using a recognized, externally verified procedure and are documented in a verifiable way. Operational efficiency gains can thus be integrated directly into climate targets, risk analyses and sustainability reports – and evidenced to internal and external stakeholders.

The AI platform · NARA AI · self-learning AI system and in use since 2023.

One artificial intelligence, four tangible effects.

NARA is the AI at the core of ECCO2: it continuously controls every heating system in your portfolio by itself — based on weather, building behavior and real demand. Classic systems only show data; the AI intervenes actively.

Lower operating costs

At least 20 % less heating energy lowers costs and helps finance further measures.

Evidenced CO₂ pathway

Fewer Scope 1/2 emissions — measured, not calculated.

ESG & reporting at the push of a button

Hard data per building and portfolio, directly for reporting.

Controllable portfolio

A consistent data basis shows where CAPEX really has an effect. Data secured and stored in Switzerland.
