In recent years the realization of passive and lowest energy houses has been pushed by political targets on federal level and on federal state level. A wide variety of know-how has been collected during the planning, construction and operation of these pioneer buildings. The experiences, especially those in collaboration with the bmvit-programme “Building of tomor-row”, are documented very well, however there are remarkably diverging attitudes to different tasks – like extra costs for the planning and constructing or additional charges for maintenance and repair – from the building developers, real estate agencies and even planning offices regarding the possi-bilities and limits for the construction of large volume residential and non residential buildings in lowest energy and passive house standard. The exchange of experiences in planning, constructing and operation of highly energy efficient build-ings happens only sporadic and does not satisfy the demand for verified knowledge and structured exchange of experiences of the building developers. From this perspective it can be observed that an increasing demand for a moderated and intensive exchange of experience between the know-how holders exists. Up to now more than 20 renowned building developers (BIG, GESIBA, ÖSW, BUWOG, ARWAG, GSWB, Kallco, VOGEWOSI, Heimat Österreich, a:h, GSW, federal state of Lower Austria and may more) have obligated themselves via a declaration of support to the participation of the project, if it will be approved. This shows the need for the present project. Overall objectives: Collection, scientific and practice-oriented synthesis and transfer of experiences from innovators, who realized and operate lowest energy and passive houses. Establish a basis for a continuing quality support, quality assurance and specialized training for future highly energy effi-cient projects in order to raise the quality of future passive houses and prevent the damage of pas-sive houses’ reputation. The target group consists primarily of the commercial and non-profit build-ing developers, real estate managers as well as clients of the public institutions, who are not only interested in the knowledge increase, but can also contribute experiences. Contents: Key contents of the “passive houses of the future academy” are: 1. Knowledge transfer within the target group by means of structured interviews in personal meet-ings and two regional, moderated and structured workshop series. 2. Dissemination of the generated knowledge by experts’ meetings e.g. wohnen+plus, “Zukunft des Wohnens” series of lectures and within the international passive house conference in April 2011 in Vienna. In addition the results will be published as specific planning and operation instructions to a broad technical community. The submitted research project particularly stands out due to: - Target group orientation: custom-made knowledge transfer within the target groups of the building developers: Management, commercial and planning department, Facility management. - Quality assurance by an independent advisory board. The board consists of experts in science, re-search and building practice and of participants of relevant standardization committees. The characteristic of the “passive house of the future academy” is: Who participates, does not only receive knowledge, but also contributes experience - in that way the benefit for all participants is guaranteed. The conditions for participation is the obligation to contribute knowledge and experience from own lowest energy and passive house projects. The personal, non-public framework of the workshops promotes an open discussion. The results of the Austria-wide workshops are documented and published in a final report as well as in specific “technical bulletins” for planners, marketing and facility management.
