What Danvak does

Danvak is a Danish professional membership association serving HVAC, energy, and indoor climate professionals. The organization operates as a community network for consulting engineers, contractors/installers, building owners, manufacturers, and educational institutions, delivering value through theme meetings, conferences, technical literature, and peer working groups. It is institutionally backed by VVS Teknisk Forening and IDA HVAC under Ingeniørforeningen IDA, with day-to-day operations and course delivery handled by Teknologisk Institut (Danish Technological Institute).

Its core offering is a structured training catalog covering ventilation, heating, cooling, sanitary systems, CTS/BMS automation, commissioning, fire safety (BR18), and DS 447 ventilation standards, plus advanced courses integrated with the HEAT2 heat-transfer calculation tool. Adjacent products include nine specialized professional groups (ventilation, heating, cooling, sanitary, commissioning, fire/safety, sustainability, smart building, and a forum group) and reference publications such as "Det Grønne Ventilationskatalog." The organization is also the Danish member of SCANVAC (Nordic) and REHVA (European Federation of HVAC Associations) and has hosted the REHVA student competition since 2005, providing an international dimension to an otherwise Denmark-centric member base.

The business model rests on three revenue streams: individual and corporate membership dues, paid enrollment in technical courses and conferences (including Firmakursus corporate in-house training), and sales from a technical bookshop. Corporate anchor members such as COWI A/S, Artelia A/S, Lindab A/S, and Lindinvent ApS participate alongside a broader long tail of individual professionals and institutions. The structure is characteristic of a nonprofit professional association, with no disclosed funding rounds, equity capital, or external investors.
