If an environmental permit is required, the final design will be made suitable for the application for the environmental permit. The drawings will be completed with the submission requirements necessary for the application. For example, the architect determines the usable surfaces according to the current NEN standard and he takes care of, among other things, daylight calculations and ventilation calculations. The necessary technical installation matters will also be recorded on a drawing by the architect. Finally, the environmental permit will be applied for by the architect.
