Smoke exhaust, such as for extracting smoke from a stairwell, only requires taking into account the geometric opening area of the windows through which the smoke can escape in case of fire.
This does not require motorised opening drives or controller elements. Smoke extraction is more complex because it also needs to handle a wide variety of requirements from fire protection assessments and conditions required by law. D+H provides authoritative advice relating to these requirements early on. In addition, D+H reviews the economic feasibility with regard to implementation. This is especially useful for NSHEV solutions, which require complex aerodynamic area calculations. Thus, D+H provides you with functional safety for your NSHEV solutions in accordance with DIN EN 12101-2 at no additional cost and even if not required by law.
