| Building Simulation & Modeling | |
How does a building perform in terms of comfort, safety and energy?
Advanced software technologies and modeling techniques, previously only used in advanced research and aeronautical / aerospace applications are nowadays available to the building industry and allow predicting the behavior of buildings with almost unlimited levels of complexity.
There are few limitations as to what can be simulated. The advances in computing power allow most physical phenomena to be mathematically modeled and numerically solved with a high degree of precision to produce accurate results within a practical timeframe.
Special criteria or demands can be verified for viability and existing problems can have their causes identified, for example the cross-contamination by pollutants such as smoke. Alternatives can be studied with relatively low additional costs, resulting in optimized solutions. New buildings can be simulated ahead of their final design and existing buildings can be modeled to verify, for example, compliance with emerging European energy regulations.
Air flow simulations can be used to determine:
- Distribution of aerosols and gases
- Flow velocity
- Pressure
- Streamlines
Comfort simulation to determine:
- Existence of drafts
- Comfort (making use of the Fanger model)
- Unpleasant radiation
- Presence of unwanted gases
Safety simulations to examine:
- Smoke development
- Exceeding MAC values (Maximum Acceptable Concentrations)
- Exceeding maximum pressures/temperatures
Energy simulations:
- Energy efficiency of complete buildings
- Energy demands for cooling, heating and ventilation
- Installation component analyses
