The current EPBD makes it necessary to plan the air tightness of the building envelope and to design it professionally to achieve the energetic aims or to obtain submitted subsidies. This is especially important for German KfW 55 and 40 buildings, passive houses and nearly zero-energy buildings. With view to the EPBD it is essential that handcrafts, energy consultants, planners and architects are well schooled in this topic.
The Air Tightness Testing and Measurement Association (ATTMA) is a professional association dedicated to promoting technical excellence and commercial effectiveness in all air tightness testing and air leakage measurement applications. It was formed in 2002 to promote the testing and measurement industry and supports its members by extending market awareness of the technology and the members' services.
