The AIDA project aims to accelerate the market entry of nearly zero-energy buildings (nZEB). This means energy efficient buildings and the use of renewable energy sources, which are both highlighted by the European legislation (e. g. 2010/31/EU). Currently, there is a lack of intense actions to spread knowledge about nZEB. It is evident, that citizens will be better prepared and more willing to adopt nZEB, if their municipality sets a positive example thus giving them direct access to and experience of nZEB. Raising awareness towards nZEB among local authorities and building planners becomes a key factor. So, in particular the target group of AIDA are primarily municipal representatives as market multipliers on the demand side, and also architects and master-builders on the supply side. AIDA offers action tailored to suit each of these groups including study tours, operational success stories, presentation of existing tools, active support for municipalities and close cooperation with key actors, such as associations of municipalities and building professionals. In summary: The core objective of AIDA is a widespread market adoption of nZEB.
