Lead project: Competence Centre „Future Building“ § aims to create innovative building components and systems that will address the fundamental changes of building industry in the next decade § Partners: 20 companies (construction materials, components, equipment industry) + 7 research institutions. Lead: Department for Building and Environment at Danube University Krems § Contribution of GBC: initiator, establishing the consortium, financing and supporting the proposal development, monitoring of progress, dissemination of results § 3. 6 mio € budget, 4 years duration, 50% private and 50% public finance § 1 st result: A new brick system Ederplan XP 50 Trionic with certificate of Passive House Institute Darmstadt § 2 nd result: Completion of a production line on comp. Hartl Haus for prefabricated timber constructed houses in passive house standard 8 § 3 rd result: a chimney for fresh air ventilation system comp. Schiedel Kamin Details http: //www. futurebuilding. at/
LOPASpre-fabricated timber constructed passive house with straw insulation and loam rendering LOPAS AG 3843 Dobersberg 3 cooperating partners The LOPAS Passive House The LOPAS Module Construction Method of erecting long lasting, energy-saving houses in ecological construction is unique worldwide. Unique is above all by the combination of an efficient ecological- biological construction system with uncompromising sustainability. The LOPAS system places above all the application of sustainable resources like clay, straw and wood. The modules are manufactured as floor-to-ceiling elements thus guaranteeing quick assembly on your building site. 10
„Sonnenplatz Großschönau“– “Test before you buy” § § § First European Passive House Village (www. probewohnen. at) allowing customers to test the house of choice by living in it for several days. Initiative combines technology and tourism promotion in a less developed region Ongoing joint research project of 17 companies to enhance the quality of the indoor environment in residential structures through controlled indoor ventilation: - Visitors will keep a log of their perceptions and experiences in regard to living quality - These subjective impressions will be compared with a wide array of measurable technical data - combined data will form a solid fact base which can be used by architects, builders, mechanical engineers and other professionals to design and build userfriendly ventilation systems 11
Targets of the Lower Austrian energy policy • • • Increase the share of renewable energy from about 25% to 50% of the final energy consumption until 2020 Increase the production of the final electricity demand from renewable energy sources to 100% until 2015 (at the moment 89% including large hydro power, wind power, biomass CHP, biogas, . . ) Increase the production of the final heat demand to 100% until 2030 from renewable energy sources (biomass, solarthermal, geothermal, …) „nearly zero emission houses“ as standard of new buildings (acc. EU building directive) - 2018 With 50% share of „klima: aktiv“ passive houses in new buildings - 2018 High quality low energy standard in the existing building stock by increase the refurbishment rate to 3% /y. (at the moment ~ 2%, < 50 k. Wh/m². y) Sources : NÖ Energiebericht 2007 und 2008, Press Release of LR Pernkopf 12
End energy consumtption in TJ in LA (development / forecast) Needed increase of energy efficiency Kohle Benzin, Diesel, Heizöle, . . Gas E. E. Fernwärme Fossile Energien Erneuerbare Energien target: 50% until 2020 from renewables Strom 13
Market pull § § § Subsidies and soft loans for the improvement of the performance of energy efficient buildings (e. g. federal government spends for refurbishment up to € 5, 000 grant/house). Building regulations are in the responsibility of the 9 provinces. The annual refurbishment rate is abt. 2% of the existing building stock, the target is 3% per year. New constructed single familiy houses: the share of passive houses is abt. 12%, increasing every year by more than 10%, the average heat demand is about 40 k. Wh/m². y decreasing to 15 k. Wh/m². y! It is expected to achieve the EU building directive “nearly zero emissions standard” earlier than 2020. The Green Building Cluster acts as hub between the companies, NGOs, the government and the market of building owners to foster green building. Development of passive houses in Austria ~ 12% in Lower Austria > 25% target 2012 The GHGs of the building sector in Lower Austria 14 decreased by 35 percent compared to 1990 level.
