Saving energy and reducing CO2e emissions of

Ventilation Systems (HVACs)

with for i four solution, you can reduce the energy consumption of the ventilation systems by up to 20%.

Our product

With the for i four solution that plugs into the existing ventilation systems (HVAC), you can get instant energy optimization of the system, monitor the performance with our dashboard and consequently reduce CO2e emissions of the ventilation systems and therefore your building. This solution reduces the energy consumption by up to 20% without any hardware installation. 

Features Description
data driven
Getting the data by our cloud based solution to your BMS or by our easy-to-connect datalogger to your ventilation control.
Energy optimization
The data is used to get the energy performance of your system and it optimizes for energy.
Customized solution
it is a tailor-maid solution for your system.
ONLY software solution
No installment of any hardware to improve system's efficiency.
CO2e accounting
The dashboard in addition to the energy consumption, gives precise CO2e calculations that can be used in sustainability accounting.
Time saving
Since it is data-driven, it does system study for you and saves time for system check up.

How it works

Our product is an adds-on to your existing ventilation system. It enables you to reduce the gap between the installation and the operation and have a clear control of the energy usage in three steps. 

Reading data

By connecting to your HVAC systems, either through BMS or directly to the HVAC, the key metrics will be acquired.


The key metrics including air flow, temperature, fans status, pressure will be analyzed and compared to the datasheet.


Precise saving figures of electricity usage and CO2e emissions including the method of implementation will be offered.


Using our product is an all-in-one solution. Not only your systems become more efficient and reduce CO2e emissions, it also gives you an easy-to-understand performance overview and provides condition monitoring of your systems. Simply, because, it is an ongoing data driven based process.
