Simulation & Analysis

We simulate and analyze your project!

Sophisticated climate, energy and facade concepts can lead to success only by holistic planning and dynamic building and system simulation programs. The “ifes” has implemented in recent decades simulations in many demanding projects. The great advantage of a simulation is not only lower investment and costs for change, but also significantly lower operating costs.

Energy Modeling

Energy modeling, short for Building Energy Modeling (often abbreviated as BEM), is the computer simulation of a building used to determine or estimate building energy usage. A virtual building is created in a software package, the building components are entered, and the building is simulated over the duration of 1 year using a weather file.


Aus den Daten der Gebäudesimulation ermitteln wir im Computermodell die optimalen Anlagen und Regelstrategien. Dabei ist der Jahresenergieverbrauch im Vergleich der Anlagen exakt erkennbar.

Daylight Simulation

We calculate for your project the light propagation and distribution of light in rooms of any geometry. Technical quantities of light, such as illuminance and luminance for daylight and artificial light can help to make predictions in the early planning stage for the lighting design. The need for artificial lighting can be determined and possible glare effects can be avoided prematurely.

Computational Fluid Dynamics (CFD)

We offer you custom computational fluid dynamics - from standard cases, to special events, because the virtual reality saves considerable costs.

Fire Simulation

Fire and smoke extraction simulations create accurate predictions nowadays for the emergence and propagation of smoke and heat in a building - a substantial aspect of the building design.
