With the relevant changes to ventilation technology standard DIN 1946-6 now requires the compilation of individual ventilation concepts for new-build and modernisation measures. The air volumes necessary for effective moisture protection are clearly defined in the process. This is designed to prevent moisture damage and mildew effectively.

For the simple, transparent application of DIN 1946-6 SIEGENIA-AUBI now has a practical tool for all those involved in construction developed - from the window manufacturer to the craftsmen. A compact hub summarizes the main parameters of the standard norm and translates abstract algorithms and tables into concrete action requirements. This not only simplifies the design demand-driven ventilation, in single and multi-family homes, but also makes the necessary procedure for property managers and homeowners to understand.

Especially in light of the notice requirement for consultants and contractors it is particularly important. The creation of an individual ventilation concept is in many cases absolutely necessary – such as for single-storey residential units in new construction or modernization, where more than one third of the existing window replaced or more than one third of the roof area to be resealed. Those who do not comply with notice requirements and verification can at a later date possibly be held liable.

Step-by-step to a needs-based ventilation concept
Using this clever consultancy tool is as simple as it is effective. In the first step, the building type and number of storeys is determined. In doing so, one differentiates between new-build and refurbishment construction projects. Next follows the evaluation of the existing thermal insulation and the determination wind area/zone. Based on these parameters, it can be reliably established as to whether ventilation technology measures in accordance with DIN 1946-6 are to be recommended or are mandatory.

SIEGENIA-AUBI also provides important assistance in determining the necessary volume flow that depends on an apartment’s useable floor space: the company´s wall and window ventilators are presented in a compact overview, assigned unambiguously in accordance with the different ventilation level requirements – ranging from moisture protection up to intensive ventilation. This new consultancy tool is available with immediate effect.
