The 3rd European BlowerDoor Symposium, which takes place on May 30th- 31st, 2008, at the Ramada Plaza Hotel, Kassel (Germany), will include an exhibition and a manufacturers’ session and will deal with the ascertainment of the building stock, with detailed planning and the professional and durable production of the airtight envelope, the quality assurance at the building and a stronger interlocking between civil engineering and building services. The air-tightness of ventilation systems and the avoidance of mould will also be discussed.

It is organized by the Energie- und Umweltzentrum am Deister e.u.[z.] (Deister Energy and Environment Centre) and co-organised by the Verband für Wohnungslüftung e. V. (Dwelling Ventilation Association) and the Verband für Angewandte Thermografie e. V. (Applied Thermography Association). As with the first two symposiums, within the community of people working in the building sector in Europe there is much to learn from each other, since the countries pursue different approaches with the individual topics and worked out the topics in different depth. A transnational exchange of experience shall continue and will weave the network of the participants more closely and more firmly.

The conference is integrated into the European Union project ASIEPI („Assessment and Improvement of the EPBD Impact“) and is aimed at architects, craftsmen, blower door users, thermographers, building experts, contractors, energy consultants, scientists, researchers, advisers, planners or decision-makers in the construction-related authorities. According to the organizers press release, the symposium will cover the following subjects: air-tightness examination methods for quality assurance, measurement, concepts and durable links in new and existing buildings, effects of insufficient air-tightness, air-tightness and economy, mechanical ventilation in residential buildings, mould, current standards and directives, technical regulations and legal aspects.
