IMCD is investing in research for new Green Building Technology

Direct Air Capture in the Built Environment - a novel ventilation technology

IMCD supports visionary research project Direct Air Capture in the Built Environment (DACBE), a novel ventilation concept for large building complexes.

Racing to net zero emissions

By 2050 the European Union wants to be climate-neutral, with net zero greenhouse gas emissions such as carbon dioxide. However, experts claim that emitting less carbon dioxide alone will no longer be enough. New technologies to reduce greenhouse gas emissions need to be explored.

At the same time, the constantly growing demand for energy needs to be reduced. Particularly, the built environment holds a great potential to reduce emissions and energy consumption, as construction, usage, renovation, and demolition of buildings in the European Union causes about 40% of the energy consumption and 36% of greenhouse gas emissions1.
IMCD is committed to play a role in this process. Therefore, we are funding under the scope of the IMCD Cares Fund, a new research project that is being conducted by the European University of Applied Sciences (EU|FH) in Brühl, which is looking into the question of how negative emissions in the built environment can be generated to get closer to achieving these climate goals.

Managing Director at IMCD Benelux

"As a solution oriented company, sustainability is very close to our hearts. That is why IMCD is constantly looking for innovative solutions with our customers and suppliers to achieve sustainability goals together. By supporting visionary research projects, such as the DACBE project, we set an example and contribute to a better future.
At the same time, this kind of partnership with the European University of Applied Sciences is very valuable. The collaboration is exemplary for the practical relevance of the dual training and a great benefit for our company, as we have motivated and highly qualified junior staff during and after their studies."

Direct Air Capture in the Built Environment

A future technology in demand

The research team, led by Prof. Dr. Sascha Nehr, head of the department Management and Engineering at EU|FH, is now elaborating the potential to reduce the costs and energy consumption by using a technology that captures carbon dioxide, called Direct Air Capture (DAC).

The idea is to use the DAC technology in a novel ventilation concept, that actively removes CO2 from building exhaust air, filters remaining impurities and recirculates the air back to the building at nearly the same temperature without the use of heat exchangers.
The overall goal is to achieve total energy savings in combination with cost-efficient CO2 capture while improving indoor air quality in large building complexes.

The use of direct air capture technology in exhaust air could be of interest in the future, especially for healthcare and education buildings or for large administrative and office buildings. This approach is expected to make a significant contribution to the development of business models in emerging circular economies.

The threefold approach of DACBE aims to 

Improve indoor air quality through efficient ventilation in large building complexes.
Exploit energy saving potentials through reduced air conditioning demands.


Capture CO2 from building exhaust air to reuse in decentralised systems.

Direct Air Capture 
a technology in use

The DAC technology is already used in atmospheric air.
It is driven, by only a few companies worldwide and requires large ventilators and heating, which causes a high energy expenditure.
