Planning &
Quality Assurance

For more than 20 years, we advise architects, engineers, investors and clients. We investigate by simulations and engineering services, if the requirements of the planning have the desired effects.



Certification &

Through a certification with a seal of approval, the value of a property is often improved. Modern architecture and new materials require more modern planning tools.


Quality and diversity

Project overview

Ifes has developed comprehensive energy and climate concepts in many projects or performed simulations. All objects are trendsetting and sustainable buildings, which fulfill the critical aspects of sustainability. We have also certified many of these buildings. In this way, the “ifes” helped many projects to a high profile Green Building Label.
You can request us for abstracts of these reference projects. If you have any further questions about individual projects, please do not hesitate to contact us.

ifes auf der FeuerTRUTZ Fachmesse

23.02.2017 / Cologne - IFES holds a lecture about the compliance of fire protecting requirements with the help of simulations at FeuerTRUTZ, the fair for preventive fire protection.

In case of a rebuilding, conversion or renovation of special buildings, it is a major challenge to implement current fire protection requirements within the existing building concept.

Due to structural and cost reasons often a compliance with standard limit values is not possible. Simulations take into account both physical / structural aspects and the fire protection control. Thus, it is possible to map the interaction of different fire protection measures realistically and even solve complex problems with focus on realistic situations and economic solutions.

The target group of the event were fire protection engineers, building system engineers, project controllers and representatives of the fire department and building authorities.
