Facade Pressure Coefficients

About this project

Accurate wind pressure coefficients in thermal modelling software (building performance modelling) are critical to evaluating several key design outputs on buildings. The greatest impact of inaccurate wind pressure coefficients will be on the calculation of airflow through openings and thus ventilation, fresh air rates, cooling and overheating assessments can all be adversely affected. Most standard energy/thermal software has an oversimplified treatment of wind pressure which is also poorly understood and applied by software users. SimScale can quickly and accurately calculate transient wind flows and pressures around buildings and on building facades. These can be used as in input into energy/thermal software for more accurate building performance modelling.
