Longlife will develop practices, innovative technologies, unified procedures and guidelines for and subsequently the design of a prototype of a sustainable, energy efficient and resource saving residential building in the Baltic Sea Region. The above mentioned knowledge will be transferred, according to Gothenburg, between Denmark, Germany, Lithuania, Poland and Russia and can and should be applied in other countries too. Through this transfer differences in practices, technologies, procedures, rules and institutional structures in the BSR will hence be minimized. In a first step existing procedures for planning, permit and tendering, practices for developing and operating housing and technologies for construction of buildings will be gathered and analyzed for the participating countries. This comparative overview as output will already lead to added transnational value. In a second step requirements and guidelines will be jointly developed to improve the existing procedures, practices and technologies to new, innovative and higher standards under the aspects of energy efficiency, sustainability, resource saving buildings and low lifecycle costs. The output in form of a guideline is an added transnational value and is intended to be used by authorities, chambers, association etc. for future legislation and as a definition of obliging standards. In the third step the developed requirements, procedures and technologies will be jointly implemented in a prototype residential building. This will be done in a bottom up approach – start from the existing level and improve in little steps - and a top down approach – define the state of the art. The prototype will be adapted at the end for country specific requirements. A completely designed building is the output and will be handed over and can be used by regional, national and EU-bodies, planners, housing associations, developers, companies and SMEs to foster a subsequent realization of the prototype as pilot project and to prepare concrete investments. The prototype building will be certificated as a sustainable building. The good practice solutions and innovative technologies should also be applied to other building types like kinder gardens, hospitals and offices. Longlife will also propose elements for future financing through EU funds. Universities, public administrations and housing associations from each participating country work jointly in national units, which will distribute the knowledge in each country, and in three transnational competence teams (universities –science, administration – procedures, housing associations – practice), which develop and share the knowledge in the transnational context. The establishment of the "BAltic Sea Housing Development Association – BASHDA will continue the cooperation after conclusion of the project Longlife. Achievements: Longlife was working with the method of triple helix in three competence teams.Team 1- Engineering and building technology standards - scienceTeam 2- Administration procedures, licensing and tendering rules - administrationTeam 3- Economical and financial basis – public companiesThe virtual project space- share point was the Longlife transnational office. It was working to guarantee the transfer of extensive data and as a base for the interchange project information. This virtual office was very useful in preparing the pilot project. The national data sets of the pilot buildings were very large. All partners were using this office also to get the actual informations and exchange the available documents. At the Longlife web page, www.longlife-world.eu, news are available as a diary. There are also information about coming events, press releases and Longlife outputs. The results of Longlife are published in reports.Report Longlife 1 Analyze and Comparison, report Longlife 2 Development of standardsand report Longlife 3, prototype design and pilot projects.Longlife developed some tools to measure the efficiency from the buildings, e.g. energy consumption, cost efficiency, CO2 emission. These tools are used to certify a building with the Longlife Performance Pass (LPP). The LPP was published at the Final conference. All external expertises like Support in legal matters concerning building permits in different countries, Analysis of economic instruments for providing incentives for sustainable, energy efficient and resource saving residential buildings in the EU and Evaluation of existing assessment schemes and outline of a transnational communication and evaluation framework for residential construction towards sustainability are published.The results of the established the Longlife design class 2010 and 2011 to teach the method of the integrated design were used in the Longlife project through an evaluation process. The results of the Longlife design class 2010 are published in a reader.The exhibition Longlife design class 2010 was presented on SET2010, on the BSR Program conference Jyvaskyla and on Longlife workshop in Copenhagen 2010.Longlife was engaged in the Sustainable Energy Technologies network with yearly conferences as a good platform for innovative technologies to save energy and to use renewable energy. Longlife attended the conference in Aachen 2009, Shanghai 2010 and Istanbul 2011.The Longlife Institute e.V. was founded to continue the outstanding work and transnational cooperation around projects of sustainable, energy efficient and resource saving residential buildings. The Longlife Institute extends the projects and promotes their results along with expanding the gained network
