Data Design System

Data Design System has been developing innovative software since 1984. Their Open BIM product family DDS-CAD provides ideal tools for MEP (Mechanical, Electrical, Plumbing) experts who plan and design building services projects.

Intelligent MEP design

Providing perfectly designed Mechanical, Electrical and Plumbing (MEP) systems is one of the most important prerequisites for a building that should
operate in an economically and ecologically optimal way. Bearing this belief in mind, Data Design System (DDS) has been developing innovative Open BIM software solutions to design, calculate, simulate and document building services projects since its founding.

More than 15,000 users worldwide put their trust in the highly functional tools for MEP, heating, ventilation, air-conditioning and photovoltaic engineering. Besides consultants, installers and contractors, industrial companies and property managers are amongst its typical customers.

In a subsidiary company, DDS develops specialized software for the architecture and construction of prefabricated timber frame houses of Scandinavian style. These solutions allow architects and manufacturers operating in this particular market segment the highly efficient processing of their projects.

DDS was founded in 1984 in Norway and has been a part of the Nemetschek Group since its acquisition in 2013.
