Smoke ventilation according to EN 12101-2 - D+H Mechatronic

3 Using NSHEVs in the buildingOwing to the different requirements and safety levels in European countries, no minimum value is defined inEN 12101-2 for the performance classes. This has the disadvantage for planners that NSHEVs can be offered forsale on the German market that do not conform to the previous German minimum values. Particular attentionmust be paid when selecting NSHEVs.Requests for information to the Deutsches Institut für Bautechnik (DIBt), Berlin, and the planning authoritiesof the federal states have revealed that the German legislature does not intend to define minimum values inan environment of deregulation of German building regulations. The values for the performance classes whenplanning buildings may be – but do not have to be – defined by the state-level building regulations. Plannersand specialist companies will therefore have greater responsibility in the future.When selecting an NSHEV, it must be ensured that the performance specifications of the manufacturer are atleast equal to the performance specifications required by the location of the building. This will in future be theresponsibility of experts, as well as specialist planners and companies.The various requirements of the state-level building regulations in Germany are listed in the following table(further information is available at www.rwa-heute.de).Federal StateSmoke ventilationwhen?Smoke ventilationwhere?Smoke ventilationto what extent?Control panelswhere?Model Building Regulation(MBO)Required staircases in buildingsmore than 13 m high,or interior staircases required.At the highest point of thestaircase.Free cross sectional area of atleast 1 m².Ground floor and uppermostlanding.Baden-WuerttembergBavariaBerlinBrandenburgMore than 5 upper storeyfloors, or interior staircasesrequiredRequired staircases in buildingsmore than 13 m high,or interior staircases required.Required staircases in buildingsmore than 13 m high,or interior staircases required.More than 5 upper storeyfloors, or interior staircases.At the highest point.Windows may be designedas smoke vents if they arelocated at sufficient height.Exceptions may be permittedif the smoke can bevented by other means.At the highest point of thestaircase.At the highest point of thestaircase.At the highest point of thestaircase.Free cross sectional area of atleast 1 m².Free cross sectional area of atleast 1 m².Free cross sectional area of atleast 1 m².At least 5% of the basic areaor at least 1 m².Ground floor.
