1000 passive houses in Austria - 3rd documentation period 2006 - 2008

3rd documentation period of the joint project of IG Passivhaus Österreich to set up a detailed network documentation on a representative cross-section of all passive houses in Austria.

Short Description

Status

completed

Summary

3rd documentation period of the joint project of "IG Passivhaus Österreich" under the programme ‘Building of Tomorrow’, an initiative of the Federal Ministry for Transport, Innovation and Technology (bmvit) to set up a detailed network documentation on a representative cross-section of all passive houses in Austria.

Motivation

The ecological passive house meets the need for living quality, comfort and cosiness to an extent hardly yet reached, both in single-family and multi-family homes and public and commercial buildings. It is the most consistent and economic concept of sustainable building. In order to further promote this positive development tendency it was imperative to establish a comprehensive network of passive houses from all over Austria.

Objectives

This unique network has covered 99 % of all passive houses built until 2002, 63 % built until 2004, 30 % built until 2006, and 11 % built until 2009 in Austria as successful examples of sustainable building. In total, 801 passive-house building projects, primarily from Austria, and 42 international projects have been documented. This makes up 30 % of all passive houses documented in Europe. This platform for expert planners, property developers, trades and opinion-leaders serves to expand their knowledge about the passive house, different building types, construction methods, services and technical equipment concepts and architectural solutions demonstrated in already built projects. Experiences, developments and trends towards implementing the passive house standard are opened to the general public in all Austrian provinces.

Processing method

The central online database was used as the management tool focussing exclusively on the passive house for entering and managing data gathered from all over Austria in a uniform data entry mask. The user can select permanently updated buildings by using targeted search criteria and obtains various evaluations also in the form of charts and diagrams. The purpose is to provide maximum market diffusion in order to more rapidly disseminate information about the passive house.

Data

The criteria for including passive houses in the IG Passivhaus joint project are solely those set up by the Passivhaus Institut Darmstadt! This secures the high scientific quality and offers a major contribution to raise the general awareness of the high quality standard.

The buildings are subdivided in five categories:

  • Category "Passive-house residential buildings with a heating load < 10 W/m²"
  • Category "Passive-house residential buildings with an energy requirement < 15 kWh/m²a"
  • Category "Residential buildings close to passive houses with an energy requirement of 15 to 20 kWh/m²a"
  • Category "Passive-house special-purpose buildings"
  • Category "Refurbishment of existing buildings with passive-house components"

Results

Due to the broad basis of cooperation in capturing planned and already built passive houses in Austria, as of April 25, 2010, the essential data of a total of 801 passive houses, 759 of them in Austria covering around 5341 residential units, were gathered, documented and made available on the Internet.

  • 124 multi-family and row houses with a total useful floor space of 313,365m²
  • 509 single-family and semi-detached houses with a total useful floor space of 89,130m²
  • 62 schools, nursery schools, special-purpose buildings with a total useful floor space of 147,800m²
  • 64 office, commercial, administrative buildings with a total useful floor space of 76,902m²
  • 759 buildings in Austria: total useful floor space 627,197m²
  • 42 international buildings from 13 countries with a total useful floor space of 25,506m²

801 buildings included in the database with a total useful floor space of 652,704m²

(Germany: 1281 documented buildings with a total useful floor space of approx. 485,500m²)

The passive house market has rapidly increased

  • 12,5 % of all new buildings as per end of 2009, 25 % as per end of 2010 and around 90 % share of passive house standard as per end of 2015
  • End of 2009 – 6,850 buildings with around 12,000 residential units (RU) and 30,000 passive house residents
  • In Austria 5 times more passive-house buildings per 1 million inhabitants than in Germany or Switzerland
  • 11 of the 14 largest passive houses are located in Austria as well as the largest refurbished building
  • 759 documented buildings from Austria with a total floor space of 627,197 m²

Further comparisons (of provinces, technique), analysis and cognitions can be found in the final report (only in German).

The passive-house building database is currently visited by up to 85,000 users per month on the four websites:
