3 1. National distinctions Legislation Methodology Certificates Recommendations Accreditation Decentralized responsibilities for the EPBD implementation (provinces). Attempt of harmonization with a guideline from Austrian Institute of Construction Engineering. The energy performance is epressed only on the base of the calculated heat demand. The electricity demand is only given as an information. Energy performance (heating) is epressed only with one scale for all building types. A recommendation has to be given, how to reach one class more and how to reach new building standard for eisting buildings. Organizational based accreditation system 2. Legal framework 2.1. Initial historical situation Energy-related requirements were introduced in different provinces to different times (normally at the end of the seventies) based on respective building regulations (U value requirements). For eisting buildings there were no requirements ecept in the course of housing advancements (subsidies). Since 1997 in Styria in the course of subsidies for new buildings were issued always energy certificates. Subsidies were only awarded if a certain heat demand and certain requirements to the heating systems were held. For eisting buildings the subsidies were awarded if a certain thickness of insulating material were used. Implementation of general energy related requirements Implementation of energy performance certificates on a legislation base (independent of EPBD) Implementation of energy performance certificates on a base of a national program (independent of EPBD) Regional limited activities in the field of energy performance certificates from independent organisations or city councils. Date Remark 1950 Only heat, only new buildings 1997 Only heat, Styria 2.2. National participants of implementation The governments of the regions (Länder) are responsible for the implementation. The central government has the role to coordinate the harmonization process among the regions. A relevant contribution came from the Austrian Institute of Construction and Engineering in terms of developing the new Standards. The harmonization process and the development of the standards were supported by a coordinating committee with members from each regions Status of national implementation On May 24 th 2006 the Austrian Parliament passed the Energy Certification Providing Act which sellers and landlords providing energy certificates for buildings when they are sold or rented. The obligation for providing energy certificates for new buildings was come into force on January 1 st 2008 and for eisting buildings on January 1 st The Austrian Institute of Construction and Engineering published in April 2007 a guideline (OIB Richtlinie 6). This guideline describes the methodology to calculate energy performance and presents a layout for a energy performance certificate. But this guideline together with the Energy Certification Providing Act is only a recommendation for the regions. Until now all region ecept Lower Austria and Salzburg has implemented the guideline and the Energy Certification Providing Act with minor adaptations Time schedule of energy performance certification Time since the issuing of energy performance certificates is/will be mandatory: Building type Date Remark New buildings, residential Jan 2008 New buildings, non residential Jan 2009

Types and characteristics of methodologies Calculation of the energy demand is based on the thermal quality (transmission heat losses) of the building envelope, geometry (surface-volume ratio), solar and interior gains and hygienic aeration heat losses. The time base for the holistic model (energy flow) is monthly. The methodologies are mentioned in OIB-Guideline (OIB Richtlinie 6 Energieeinsparung und Wärmeschutz OIB /07 und Leitfaden Energietechnisches Verhalten von Gebäuden OIB /07) and determined in the Austrian standards (ÖNORMen). The national law (Energieausweis-Vorlage-Gesetz EAVG / Bundesgesetzblatt 137/2008) is regulating the submission obligation of energy certificates but not the methodology. For eample in the province Stryria the Styrian law (Landesgesetz 27/2008) determined amongst others the use of the OIB guideline No Methodology Purpose Origin Characteristics energy usage Remarks New building Eisting building Residential building Non residential building Public building New developed for EPBD Eisting adopted for EPBD Eiting methodology Operational rating Asset rating (holistic model) Asset rating (factor model) Simplification available Heating Hot water Lighting Cooling Ventilation 1 OIB guideline 6 Time period of holistic model, asset rating monthly 3.2.

Reference value depends on the geometry of the building Main requirement only on the base of heat. Reference value depends on the geometry of the building, Different Reference values for RES and NonRES National distincions For buildings with ventilation systems including heat recovery systems, the value for the main requirement (heat demand) is reduced. The efficiency of heat recovery systems is so neutralized with the calculation method Major renovation (eisting building) Definition Major renovation : National definition of major renovation The definition is in the responsibility of the provinces. But there is a definition in the OIB-Guideline as following: A major renovation is eistent if the building has more than 1000 m² floor area, the whole renovation costs eceed 25% of the building value or if 25% of the building envelope or if 3 of the main components of a building (windows or front or roof or heating

6 system ) are renovated Requirement for major renovations : Same requirement like new buildings Same methodology like new buildings, but lower requirements Different methodology Reference value for heat demand is reduced. Also reduced requirements for components Eisting building general Beside for major renovation no further requirements for eisting buildings eist General requirements for renovations eists General requirements for eisting buildings independent of renovation eists 4.4. Building Permission The proof of building permission is provided with the energy certificate The proof of permission has to be made before start of construction The proof of permission has to be made before usage Other Is planned 5. Energy performance certificates 5.1. Types and characteristics of energy performance certificates First page of the certificate includes the scale. The scale is influenced only by the heat demand but not by end energy demand. Second page includes the end energy demand of the different usages and the requirements, as far as they eist. The energy performance certificate has to be followed by an anne with the recommendation, input data (geometry, physics relation to construction, data of energy systems ), used standards and tools. The recommendation is only necessary for eisting buildings. Certificates for residential and non residential buildings have the same design only the non residential certificate has more information regarding the end energy demand. The classes are for both types the same. For other buildings like industrial buildings the label on the first page is left away and only the heat demand is indicated on the second page. Monuments and churches for eample has not the obligation to issue an energy performance certificate.

Recommendations are created automatically Recommendations are a result of tick bo information Recommendations are created by the epert individually Energy savings are calculated To recommend measures to reach one class better and to reach new building standard, the savings has to be assessed. Money savings are calculated Savings are calculated in total for all recommendations Savings are calculated for each of the recommendations 5.5. Onsite visit An onsite visit of the epert is a mandatory part of the certification The information can be delivered by the owner, on site visit is not necessary Building data can be provided by the owner 6. Independent eperts 6.1. Training There are different voluntary training courses (e.g. EU-Gebäude-Richlinien Kurs, A-Kurs, F-Kurs). For eample there is a course of the Styrian government - LEV (LandesEnergieVerein). One part of the course is processed by e- learning. The course needs at least several weeks (including the final eamination) Training is organized by the government

8 Training is organized by private organisation on a base of a mandatory curriculum Private training is available The participation of a training is mandatory for the epert Duration of the training less than one day Duration of the training between one and three days Duration of the training more than three days Different trainings available Different trainings available Different trainings available Duration not specified Different trainings available 6.2. Accreditation The Austrian Chamber of Commerce has determined a organisational based accreditation according to the trade laws. For eample relevant engineering departments, architecture departments, planner etc. are allowed to issue energy certificates. There is no individual authorisation and there are no qualifications. Only the whole department is accredited. Individual (personal) accreditation Organisational based accreditation Accreditation is done by an eam or a quality assurance Accreditation is done automatically according to special education or organisational requirements Accreditation is carried out by the government or a governmental organisation Accreditation is carried out by private organisations under the roles of the government Different accreditation levels or types eist for different building types Validity of the accreditation No restriction of validity 6.3.

The energy performance certificates will be quality assured The quality assurance is done by governmental organisation The quality assurance is done by private organisation Within the quality assurance samples are collected Incorrect issuing of certificates causes penalties for the epert With some eeptions in the regions 7.2. Data collecting The data of the energy performance certificate are collected centrally Actually no central data collection eists, but the implementation is planned The results are evaluated and available for the public The results are not available for the public A central database (GWR) for all Austrian energy certificates is intended - maybe at the end of The GWR is eecuted by the Austrian statistics institute. A central administration for the Austrian database may be epected 7.3. Financing Overheads are carried out and/or paid by the government or a governmental organisation Overheads are paid due a fee on each certificate to the government (governmental fee). Overheads are paid due a fee on each certificate to a private organisation (private fee). 8. Eperiences, evaluation, costs 8.1.

Costs of the energy performance certification As far as prices are not fied by the government, time and costs differ according to the size of the building and the availability and quality of building data. Beside the fied prices, the costs shown below are estimations, which the project partners made out of their own eperiences and public available sources. But the market for energy certifications is still not settled. The shown range of costs is an estimation, variances in both directions are possible.

Acceptance of the energy performance certificates Results feedback 10. Plans for future development It is intended to strengthen the requirements for residential and non-residential buildings and to introduce the use of renewable energies by law, step by step (some provinces have already introduced a mandatory passive house standard or mandatory use of solar energy for some residential buildings). Change of the accreditation and quality assurance system from a organisational to a private base

12 Anne: Energy Performance Certificate 1. General There are three different types of energy certificates: Residential buildings Non-residential buildings (office buildings; kindergarten and compulsory schools; secondary schools and colleges; hospitals; nursing homes; boarding houses; hotels, restaurants; event facilities; sports facilities ; shops) Other conditioned buildings In the case of non-residential buildings several energy demands are calculated (e.g. ventilation, cooling, lighting etc.). Only the heat demand is influencing the scaling on page 1. The End energy demand and its requirements are mentioned on page 2. In the case of eisting building a several page mentioned measure suggestions to reach a lower class and suggestions to fulfil the requirements for new buildings (always only regarding the building construction and not the heating system). Eample: The eisting class is D. To reach class B, 10 cm insulation of eterior wall and 20 cm insulation of ceiling are necessary. To fulfil the OIB-Guideline the eterior wall must be insulated with min. 8 cm insulation, the top ceiling with min. 20 cm insulation and the cellar ceiling with min. 6 cm insulation. The windows must be changed by new ones with U- Value of ma. 1,4 W/m²K. The door must be changed by a new one with a ma. U-Value of 1,7 W/m²K.
