Abstract

Target of the projects is, to build up an international platform for Passivhaus actors with the European Passivhaus database 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

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

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

1 Target of the intention

With the project passivehousedatabase.eu an international (in first step European) internet based database shall be developed 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

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

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

Additional the calculation will be possible without any household current, to have a better comparison to other building standards

d Additional the detailed compilation and evaluation of the kind of energy

support and production with renewable energy as photovoltaic, thermal

collectors, wind power, geothermal energy, biomass, pellets and heat pumps

e Broad multilingualism from beginning: Instead of being just in the original language, the projects should be in English and seven additional

languages translated This implements the complete data structure By the

time the database shall be translated in many more languages This is very important, to reach people from every countries

f Extensive multilingual multi-functionality: Therewith cross-border and

cross-language activities can be organized and coordinated Special

activities will be the international days of Passivhaus and the

international Passivhaus meeting There will be additional functions for

communication as an area for press relation etc

g Expansion of the statistic analyses: The international database offers

new possibilities of analysing the actual portfolio The concentrated

presence of Passivhaus projects gives an account on the outstanding

competence of the Passivhaus sector in those countries This is the

fundament for knowledge, studies and political decisions

h The Passivhaus database will because the voice of energy efficiency in

Europe Although everybody is clear about that 100% renewable energy is

just possible with massive efforts in energy efficiency, there is still no comparable Lobby for energy efficiency as in the energy sector With the database all the players for energy efficiency, specially the SMB, can get connected and visible

1 Cooperation:

a Three key partners: close unlimited partnership between IG Passivhaus Austria

and the Passivhaus Dienstleistung GmbH, Darmstadt This partnership is based

on a contractual fundament These project partners are the provider of the European Passivhaus database The building faculty Innsbruck with its leader Wolfgang Feist from chair in building physics will be the third partner who will be supporting and mediating the team

b 9 countries involved: The international Passivhaus organisations that are part of

Structure of the database:

One database: Access to the entry mask will be offered to the international partners Operation, quality assurance and communication will be done by the Austrian and German operators The operators will guarantee quality assurance for Passivhaus and Passivhaus-Plus standard by publishing these standards on an international level

The organization of the administration of the database:

Illustration of the basic functionality of the database:

Beginning with the central database every country can use nine basic functions in their language: documentation and illustration of projects, documentation and compilation of publications of the projects or the database, organization and handling of the “international days of Passivhaus”, search function, extensive statistic analysis, yellow pages, “context help”, area in the single chapters for user and administrator

As comparable Passivhaus databases there are just the examples of the Passivhaus Institut, which is supervised by the Passivhaus Dienstleistung GmbH

at www.passivhaus-info.de and of the IG Passivhaus Österreich at

The PASS-NET project „European-wide database“ is connected to the

„passivehousedatabase.eu“ which is supported by the Austrian Ministry of traffic, innovation and technology through the program „Haus der Zukunft plus“

The database is an important base 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 By the connection of projects and evaluation data this database will be the most fundamental basis worldwide for most energy efficient buildings Because of the multilingualism and the quality assurance it will boost the Passivhaus in new regions

3 Methodology and data capture

The international and interactive network is an independent service provider who

acts as a community in PASS-NET project The work package is leaded by the

IG Passivhaus which is working together with its 10 European partners

Host:

PHD Passivhaus Dienstleistungs GmbH, Germany

IG Passivhaus Österreich, Austria

PASS-NET partners:

IG Passivhaus Österreich

For the acceptance of Passivhaus projects in the international database, the projects get compared to the criteria of the Passivhaus Institut Darmstadt The projects are classified in following categories:

- Heat demand smaller than 15 KWh/m²a (according to PHPP)

- n50 < 0,6 measured

- PH-window UW < 0,85 W/m²k (PH-Institute certified or other certificate)

- Heat demand up to 30 kWh/m²a according to PHPP or 20 kWh/m²a according

to national energy performance certificate

- n50 < 0,6 measured

To get a significant structure of data, the documented projects are calculated according to PHPP beside the calculation according to the national energy performance certificate Additional the calculation according to PHHP assures the quality of the evaluated data

All projects are proved on plausibility If necessary a correction of the data will get enquired

Beside that, the projects don’t need to fulfil any other criteria, what means:

- the projects can be built without any subsidies

- the involved companies don’t need to be member of any Passivhaus Network

- the input of data is complete free and without any charge

The statistic analyses of this interactive project will be shown in several graphs They will be public and free for everybody Because of enormous number of Passivhaus projects, the diagrams will be very representative and significant

The project information in the Passivhaus database consists of the data of the clients, planner or other involved companies We bother to enlarge and actualise the information all the time The Pass-Net consortium or any third party can’t warrant the correctness, completeness or actuality of the database

Any liability, especially any damages or consequences which occur because of the use of the offered knowledge, is excluded Additional there can’t be any liability of any rights on any data or information of a third party

5 Results and reasoning

There has been an intensive cooperation for the entry of the planned and built Passivhaus projects in Europe between the 10 PASS-NET countries Because of this and the already documented Passivhaus projects in the existing databases in Germany and Austria there are already documented 2,047 Passivhaus buildings per 31st of May 2009 These buildings are including 8,448 flats and lot of non-residential buildings which will be online soon

These documented projects are a relevant part of the European Passivhaus sector and offer an outstanding platform for planner, property developer, business and opinion leader in the database

The following analyses are showing that just Germany and Austria are having the only extensive documentation of Passivhaus development This is possible because of the detailed databases this countries have

In compare the other countries have a very low documentation and just a few built Passivhaus buildings This shall be changed with the European database

Einheit = Anzahl Objekte kumuliert / Amount of objects accumulated

The guessed number of realized Passivhaus buildings in the 10 PASS-NET countries rises a lot every year But there is still a big difference in the amount

The 194 documented non-residential have together about 328,000 m² treated floor area, which is a third of all documented Passivhaus buildings

Schools, kindergartens, student homes, nursing homes and administrative buildings are getting increasingly more important For these buildings Passivhaus

offers additional benefits, like better concentrated children in the school because of less CO2 in the rooms

There are also built more offices, commercial buildings, factories and

buildings for special use since some years This doesn’t offers only immense

energy savings, especially including enormous savings for cooling in summer The Passivhaus can be used as a marketing instrument to show the customers a sense
