Since the first such event in 2008, around 3,000 trade partners, heating contractors, designers, architects and engineers have taken part. This shows that there is a great need for factual information and clarification of political and technological issues.

At these events renowned experts from politics, research institutes and the heating sector present their views, highlight solutions and take part in question-and-answer sessions.

Alliance for Sustainability

Viessmann set up the Alliance for Sustainability online forum for the wider public. The website www.allianz-pro-nachhaltigkeit.de collects and collates information about sustainable building, housing and modernization. Previously, this information has either been incomplete or only available in a complicated format.

The long-term goal of the "Alliance for Sustainability" is on the one hand to achieve sustainable use of natural resources and on the other to make building services carbon-neutral. The intention is to take the issue of sustainability into the everyday life of the community and embed it there.
