The database will offer universal knowledge about Passivhaus standard and will support this sustainable and resource saving standard. The database is part of the PASS-NET project which is supported by Intelligent Energy Europe. Within this project it is Workpackage 5 „Establishment of a European-wide database which describes and promotes pilot projects“. Additional this database is supported by the science program „Haus der Zukunft plus“ from the Austrian ministry of traffic, innovation and technology. In particular, the database is to serve as an international acknowledged database for decision-makers of the European Commission and the European Parliament as well as all national and European bodies for implementing the European climate protection and energy strategy objectives for 2020. That’s in accordance to the recommendation of the European Parliament of 31 January 2008 to contribute in establishing the passive house as the general standard in Europe by the year 2011. It pursuant to the resolution tabled by the EU Parliament on 4 February 2009 to achieve the target of zero net energy balance in new residential buildings from 2015 onwards, too. This is to ensure that the urgently needed targets can be reached according to which Europe by the year 2020 must reduce greenhouse-gas emissions by as much as 25 – 40% and by the year 2050 by at least 80% of the level of 1990 in order to still contain the dramatic changes of worldwide climate as much as possible. Another important aspect of the database is to serve as a platform for proving the practicality of state-of-the-art energy-saving building standards between those of passive houses and passive houses “plus”. For this purpose, the core cooperation scheme under this project comprises both planning and implementation of the database and bringing together the data stock of the databases so far developed separately by the project partners IG Passivhaus Österreich and PHD GmbH. Those databases include the database funded by subsidies granted under the framework programme „House of the Future“ and developed by IG Passivhaus Österreich and a database financed by own funds of PHD GmbH (www.passivhausprojekte.de). The data contained in both databases will be edited in the project, their contents reviewed for providing a structure to be applied all over Europe and harmonized for European-wide use to safeguard quality. This is done mostly by using the experience already gathered by PHD GmbH in respect of quality-assuring structures and their essential development. The database to be implemented under the project is to serve as the basis of a first European-wide, later on international database created for an indefinite period of time and operated jointly and solely by the two partners of the project. The purpose 5 of pooling and extending the data stock is to make the database offering in the target sector more attractive and increase its response. Additionally, cooperation with partners under the „Passnet“ EU project and with further international partners is envisaged so as to ensure sustainable promotion of the international aspects of the data-base and expansion of the data stock. As a first step, it is planned to prepare the information in 9 languages. This will help to establish, within a very brief time span, the world’s largest database for highly efficient buildings, which, as early as by the end of 2010, will have documented in detail and according to uniform quality standards more than 3000 passive houses, some of them passive house “plus” buildings. Data For the acceptance of Passivhaus projects in the international database, the projects get compared to the criteria of the Passivhaus Institut Darmstadt. Because of that the high science quality gets assured. It’s also an important contribution of awareness-raising. The projects are classified in three categories: Category “Passivhaus projects with the energy indicator < 15 kWh/m²a” Category “Very low energy house, (<20 kWh/m²a in heat demand)” Category “Refurbishment low energy house with ph components < 30 kWh/m²a“ As common basis for the calculation of energy characteristics the PHPP – Passivhaus Projektierungs Paket is used. Results of the first progress report – May 2009 By the cooperation on the capture of data from planned and built Passivhaus projects, 2,069 buildings including 2,047 from the PASS-NET countries could get documented. Also 8,448 Passivhaus flats were detected. • 330 multifamily and terraced houses 446,524 m² area in total • 1522 single- and two-family houses 281,666 m² area in total • 20 students and retreat home 61,336 m² area in total • 57 schools, campuses, kindergartens 75,501 m² area in total • 83 office, administration and public buildings 103,208 m² area in total • 34 commercial- and industry buildings 87,442 m² area in total 2.047 PASS-NET projects in total 1.056.257m² area in total 6 0 10.000 20.000 30.000 40.000 50.000 60.000 70.000 80.000 2 00 0 2 00 1 2 0 02 2 00 3 2 00 4 2 0 05 2006 2007 2 008 2 009 2010 2 011 2 012 DE AT BE SE GB CZ SK RO SI HR Sum of documented Passivhaus Stand 25.05.2009 Passivhaus trends in the 10 PASS-NET countries 213 395 762 32.450 21.500 14.320 46.770 71.270 1.382 2.531 4.485 6.717 9.698 Results of the 2,047 documented Passivhaus projects of the PASS-NET countries: Saved energy and emissions vs. conventionally built structures 05/2009 2,047 documented Passivhaus projects in PASS- NET countries Forecast 12/2009 21,490 built Passivhaus projects in PASS-NET countries Forecast 2015 about 260,000 Passivhaus projects in PASS-NET countries New buildings projects Retrofits projects Total Number 1,963 projects 84 projects 2,047 Objekte 21,000 projects 490 projects 21,490 Objekte 250,000 projects 10,000 projects 260,000 Objekte New buildings arera Retrofits area Total area 989,819 m² 66,438 m² 1,056,257 m² 7,042,000 m² 293,000 m² 7,335,000 m² 85,203,000 m² 6,182,000 m² 91,385,000 m² New buildings *) FED Retrofits *) FED Final energy demand/year 117,395 MWh 22,620 MWh 140,015 MWh 835,200 MWh 99,750 MWh 934,950 MWh 10,104,500 MWh 2,102,000 MWh 12,206,500 MWh Light fuel oil / year 140,015,000 lt. oil 934,950,000 lt. oil 12,206,500,000 lt. oil New buildings CO 2 savings Retrofits CO 2 savings CO 2 savings / year *) 11,740 to.

The targets are education, advertisement and quality assurance of Passivhaus standard, to assure highest energy efficiency for a sustainable and eco-friendly building. A platform for “European Public Relationship” for Passivhaus houses will be developed which will be exempt of charges for input and output for everybody. The database offers detailed information about Passivhaus standard. The European wide potential in energy savings will be documented. The unique energy standard (PHPP) will be described, which is comparable international unlike the national standards. The necessary quality assurance will get promulgated by the database. The buildings which are documented at passivehousedatabase.eu will have highest living comfort. The database should intensify the attention in Europe and international on Passivhaus standard. Additional it should document the further development to Passivhaus-Plus standard and confirm this with qualitative materials. The database supports this progress by the connection of reference projects and involved companies with technical know-how on international level. Because of that there should be generated additional demand on Passivhaus which will boost the Passivhaus-Plus as well. It is a target of the database to support the recommendation of the EU Parliament of 31 January 2008, to contribute in establishing the passive house as the general standard in Europe by the year 2011 and the resolution tabled by the EU Parliament on 4 February 2009, to achieve the target of zero net energy balance in new residential buildings from 2015 onwards. The databases is based on the Austrian IG Passivhaus database which is funded by subsidies of the „House of the Future“ programme and on the German database of PHD GmbH. It efforts a long time key role to the actors of Passivhaus sector because of following targets: 1.1 International Passivhaus database actors 1. Establishing of a platform for know-how transfers of international Passivhaus actors trough: 10 a. Core-cooperation of the IG Passivhaus Austria and the Passivhaus Dienstleistung GmbH, Darmstadt under the science advice of the institute for construction and material science of the University of Innsbruck. The cooperation covers planning and realisation of the database, as well as the consolidation of the both databases and the unlimited operation of the European database. b. Cooperation with the other PASS-NET partners. This secures the internationality of the database and the enlargement of the existing portfolio with at least 300 additional projects from 10 European countries. Because of this cooperation the database will be offered in 9 languages from the beginning. c. Integration of additional international partners. Potential partners are France, Ireland, Denmark, Switzerland, Italy, Netherlands, Hungary etc. 2. Increase of attraction and response on the database through merger of actual separated activities of different countries and enlargement of documented projects up to 3,400 till 2011. 3. Preparation of an international acknowledged database for decision makers of the EU Commission and the EU Parliament plus all European bodies for the implementation of the climate and energy targets. The European database will show that every kind of building in any region is possible in Passivhaus standard. It also will show how fast Passivhaus can boost in a region, if there are the right political decisions. 4. Establishing of a platform for confirmation of suitability (energy performance, user satisfaction, etc.) of energy efficient buildings standards as Passivhaus and Passivhaus-Plus. Because of this network of evaluation data this database will be the most substantiated basis for energy efficient buildings worldwide. Therewith the requirements, to make the Passivhaus standard to the general European building standard, will be created. 1.2 Database offer Unique size of a free accessible building database worldwide. Because of that, an enormous spectrum of population and decision makers can be reached: a. Large existing basis of data: Sum of the two most important Passivhaus databases “1000 Passivhäuser in Österreich” and passivhausprojekte.de with about 2,000 projects together. Additional integration of small databases of Passnet partners. b. Continuing enlargement of data: Increase of the database with about 1,400 international projects till end of 2011. c. Compilation of primary energy demand for heating, hot water, auxiliary- and household-current, as it is calculated for Passivhaus with PHPP.
