How it works

Our smart sensors provide millions of data points for temperature, humidity and air quality via IoT. Merging this knowledge with meteorological data, we develop “building intelligence”, a predictive understanding of the thermal flows in a building. Our AI NARA proceeds to overwrite the default parameters of the heating with data-based values, saving energy consumption.

Automated data analysis provides a better understanding of your portfolio’s energy performance and allows you to track and document a CO2 reduction plan.

CO2 reduction software

Why we are Swiss #1


Operational Excellence

We assess the building, design and assemble smart sensors, install the sensors in the building and manage their data conduits, create building gateways, ingest highly precise meteorological data and manage communication with tenants.

With +700 buildings under our management, we have developed procedures and software tools to execute huge portfolio roll-outs hassle-free: Swiss style.


Happy tenants

CO2 reduction requires a fine-tuned analysis of the building’s particularities: 52% are not homogenous and the tenants’ behaviors are as variable. In addition, the weather influences the comfort perspective – saving energy in this context is a considerable challenge.

At ECCO2, we got to the bottom of the problem. Our engineers created a mathematical model of the building. Afterwards NARA AL takes over and refines this model as well as the heating control in several hundred steps over 3 months. This results in a precise metering of heating energy and maximum savings in compliance with comfort instructions.


Precision metrics, certified

ECCO2 Building Intelligence quickly provides up to 20% energy savings. In addition, the precise information allows to drive the renovation strategy and to keep track of the progress.

With certificates from the Swiss Federal Office for the Environment and pending certificates from other countries, ECCO2’s energy savings calculation provides accurate, real-time data to maximize the impact of your strategy.
