VDI Guideline 3805

The VDI Guideline ensures that different CAD and calculation programs can import product data from different manufacturers without additional interfaces.

All the technical data required for designing the product The item numbers, DATANORM numbers and StLB numbers assigned to the product.

The geometry associated with the relevant product (in the form of disturbance spaces, connections and form blocks for complex representation)

In building services engineering, systems are increasingly planned and configured with the assistance of IT systems. This requires the product data to be available in a machine-readable format. The VDI Guideline 3805 "Product data exchange in building services" aims to create standardised dataset descriptions which permit the creation of uniform (from an IT perspective) product descriptions for each product group, with the following content: • All the technical data required for designing the product • The geometry associated with the relevant product (in the form of disturbance spaces, connections and form blocks for complex representation). • The item numbers, DATANORM numbers and StLB numbers assigned to the product. This ensures that different CAD and calculation programs can import product data from different manufacturers without additional interfaces. One can compare the format with, for example, the JPEG format, which can be read by all image processing programs. VDI 3805 covers products and components in heating, ventilation and sanitary systems. The format is manufacturer-neutral and can therefore be imported into all common CAD programs. Systemair will support you in your ventilation project from the planning phase right through to implementation – now also with data acc. VDI 3805 for Systemair residential ventilation and compact air handling units.
