ETU Software GmbH is part of the Hottgenroth Software Group based in Cologne, Germany. The company started in 1985 as Hottgenroth & Schmale, providing IT solutions for craftsmen and contracting firms. In 1995 the company was renamed to Hottgenroth Software and grew steadily by working closely with our customers and adapting our products to the challenges they had to meet. We found solutions in scientific research and participated in governmental development programs for energy efficiency in buildings. Hottgenroth/ETU Software soon became the market leader in Germany and Austria for energy assessment and certification software (compliant with the EPBD guidelines). Today our company is one of Germany’s leading software developers serving more than 60,000 users world-wide. The company is privately owned and employs over 150 dedicated specialists. We have 7 offices in Central Europe and are locally represented in Italy, Benelux, Scandinavia and the UK.
