Content

  • Statistics on the housing sector
  • Current Building regulations
  • Retrofit Scenarios
  • Costs and Benefits of Renovations
  • Best Practice Examples
slide3

Housing and dwelling stock

  • Housing and dwelling stock is about the same size in Austria and the Czech Republic.
    • 4,3 Million dwellings in the Czech Republic
    • 3.8 million dwellings in Austria
slide4

Austrian Building Stock

The Austrian Building Stock classified due to the main use

Bundesanstalt Statistik Österreich, STATISTIK AUSTRIA, 2006

slide5

Energy use in the dwelling stock(AT)

Im Auftrag des Bundesministeriums für Umwelt, Jugend und Familie, JUNGMEIER ET AL., 1996

Specific space heating demand (useful energy) of single and (two) dwelling buildings (SFH), multi family buildings (MFH, MFH-S: small MFH, MFH-B: large MFH) and non- residential buildings (NRB) in Austria classified by the building age [33], Origin data source: Jungmeier, et al. (1996)

slide6

Similarities in thermal building standards

  • Both Austrian and Czech Energy thermal-technical requirements for new as well as renovated buildings are being very similar due to the gradual harmonisation of technical standards according to the EU’s CEN standardization.
  • Therefore new buildings are far better energy parameters than old ones

Differences in thermal building standards

  • Old buildings are generally in a better condition in Austria than in the Czech Republic (CR) with a long history of panelled flats.
    • low quality of materials and construction works carried out and
    • long-time neglected maintenance
  • Building standards are on national level in Czech Republic and provincial level in Austria (harmonization is in progress)
slide7

CO2 Emissions of the dwelling stock (AT)

WIRTSCHAFTKAMMER ÖSTERREICH, Innovation & Klima, Innovative Klimastrategien für die österreichische Wirtschaft, 2006

Specific CO2-emissions of single and (two) dwelling buildings (SFH), multi family buildings (MFH, MFH-S: small MFH, MFH-G: large MFH) and non- residential buildings (NRB) in Austria classified by the building age

slide8

Current Building regulations

  • A Competency on national level
  • Legal framework for residential buildings
  • The Austrian strategy for sustainable development
  • Harmonization of building codes
  • Implementation of the EPBD
  • The Austrian government programme 2007 - 2010
  • B. Competency on level of provinces
  • Required minimum standard of heat protection
  • Subsidies
slide9

EPBD (European Performance of Buildings Directive of the European Commission, in force: probably Jan. 2008?)

  • Austria has a harmonized calculation scheme for all provinces.
  • This has been extended in 2004 by the energy efficiency of a heat source and a heating system. It will meet the full EPBD in the end of 2007.
  • No work according the EPBD has been carried out in the Czech Republic so far.

A5 The Austrian government programme 2007 - 2010

ÖSTERREICHISCHES NORMUNGSINSTITUT, ÖNORM H 5056, 2007

Measures of the Austrian government programme concerning buildings

slide15

B2 Subsidy schemes

  • New buildings and renovations are subsidized in Austria
  • In several Austrian provinces also the use of renewable energy carriers is subsidized
  • Amount of support provided
    • Austria: 2.5 billion €
    • CR several tens of millions €
slide16

B2 Subsidies in the Austrian Provinces

BUNDESMINISTERIUM FÜR FINANZEN, Daten aus den Jahresberichten der Länder seit 1989

Share of spended money for financial subsidy for renovations and new buildings in Austria over the years 1996-2004

slide17

Retrofit Scenarios

Current renovation activities

01…Installation of lifts

02…Renovation of roof covering

03…Renovation of windows in most of the

building

04…Connection to fresh water network

05…Connection to gas network

11...Renovation of facade with insulation

12...Other heat demand reduction measures

13...Installation of water and sanitary

equipment

14...Installation of decentralized waste water treatment plant

06…Connection to waste water network

07…Connection to district heating system

08…Installation of a central heating system in the whole

building

09...Installation of "alternative" heat delivery systems

10...Renovation of facade without insulation

STATISTIK AUSTRIA, Gebäude- und Wohnungszählung, 2004

Retrofit Scenarios

Importance of the thermal renovation rate

WIRTSCHAFTKAMMER ÖSTERREICH, Innovation & Klima, 2006

Illustration of the potential for reduction of CO2-emissions due of single family buildings (SFH) and multi family buildings (MFH) to a raise of the renovation rate and change of heating energy source to renewable energy (20% change from oil to biomass/solar energy) for one- and multi-family dwellings

slide19

Retrofit Scenarios

Importance of the thermal renovation rate

WIRTSCHAFTKAMMER ÖSTERREICH, Innovation & Klima, 2006

Trend scenario of thermal renovation and fuel switch of all Austrian dwellings

slide20

Retrofit Scenarios

Ideas for renovations

  • 1. Comfort & Cash
  • 2. National State & Buildings
  • rent law (MRG)
  • co-operative housing law (WGG)
  • condominium law (WEG)
  • 3. Provinces & Buildings
  • Reduction of subsidies for detached houses
  • Reduction of subsidies for solely maintenance works
  • 4. Business & Buildings
slide21

Retrofit Scenarios

Ideas for renovations

  • Comfort & Cash
  • The idea of this measure is to install an image-campaign to increase comfort of living and decrease CO2-emissions. This aim should be realised by following actions:
      • - raising of the rate of thermal retrofitting
      • - replacement of existing buildings which cannot be renovated usefully
      • - raising of the renovation rate of systems for building services
      • - increased use of renewable energy sources
slide22

Retrofit Scenarios

Ideas for renovations

  • 2. National State & Buildings
  • - rent law (MRG)
  • - co-operative housing law (WGG)
  • - condominium law (WEG)
slide23

Retrofit Scenarios

Ideas for renovations

  • Provinces & Buildings
  • - Reduction of subsidies for detached houses
  • - Reduction of subsidies for solely maintenance works
slide24

Retrofit Scenarios

Ideas for renovations

  • 4. Business & Buildings
  • Experiences of Austrian real estate companies (BIG, LIG) show that thermal renovations can be done in combination with long-lasting contracting-agreements.
  • The duration of those contracts is at maximum ten years which implies problems:
      • Such a short duration provides a return of investment for renovation of the
      • systems for building services but not for a heat insulation of the building.
      • Longer runtimes are not practicable due to the fact that no private firms are able to
      • provide durations for more than ten years.
slide25

  • Cooperation in new housing construction (cheap low energy buildings)
  • Helping the Czech republic to establish a research program similar to the Austrian “Building of Tomorrow” program.
