1. Presentation SOLANOVA, January 2003 Department of Building Energetics and Service Systems Department of Energetics and Energy Systems Budapest University of Tecnology and Economics Center for Environmental Systems Research University of Kassel SOLANOVA - The Project SOLANOVA – Solar- supported, integrated eco-efficient renovation of large residential buildings and heat-supply- systems

2. Presentation SOLANOVA, January 2003 Department of Building Energetics and Service Systems Department of Energetics and Energy Systems Budapest University of Tecnology and Economics Center for Environmental Systems Research University of Kassel SOLANOVA - Situation 1 – huge stock of old-style multi-flat buildings (Hungary: 600,000 flats) needs to be restored in a sustainable way to avoid a "lost-opportunity" for another 30-50 years – current renovations only result in minimal savings

3. Presentation SOLANOVA, January 2003 Department of Building Energetics and Service Systems Department of Energetics and Energy Systems Budapest University of Tecnology and Economics Center for Environmental Systems Research University of Kassel SOLANOVA - Situation 2 – very low energy prices do not reflect real market conditions – therefore many occupants in energy wasting flats will suffer from real prices in the near future – companies waiting for enormous potential of implementing renovation measures

4. Presentation SOLANOVA, January 2003 Department of Building Energetics and Service Systems Department of Energetics and Energy Systems Budapest University of Tecnology and Economics Center for Environmental Systems Research University of Kassel SOLANOVA - Objectives Making ongoing renovation sustainable – restructuring large panel buildings to passive-houses or ultra-low-energy-houses (15 to 45 kWh/m2a) – trigger: renovation of one selected building to this level – to show large potential for solar energy for heating (cooling) and hot water by installing solar thermal panels – investigation of change of inhabitants‘ social situation (comfort, health, financial situation) – middle-term: renovation of whole residential quarter – to serve as example for all similar quarters in Hungary – strong focus on teaching and disseminating the results

5. Presentation SOLANOVA, January 2003 Department of Building Energetics and Service Systems Department of Energetics and Energy Systems Budapest University of Tecnology and Economics Center for Environmental Systems Research University of Kassel SOLANOVA - Demo Building The most probable building: Located in Dunaújváros Cooperation with Intercisa Housing Association

6. Presentation SOLANOVA, January 2003 Department of Building Energetics and Service Systems Department of Energetics and Energy Systems Budapest University of Tecnology and Economics Center for Environmental Systems Research University of Kassel Project idea: SOLANOVA Retrofit from bad state to passive house standard

7. Presentation SOLANOVA, January 2003 Department of Building Energetics and Service Systems Department of Energetics and Energy Systems Budapest University of Tecnology and Economics Center for Environmental Systems Research University of Kassel SOLANOVA - Dissemination of Results Dissemination actions: – Website with online monitoring – possibility for companies to advertise on website – demo- and education centre in the building – development of training materials (software and written material) – training courses for various interested groups – concepts for „renovation contracting“ – international conference, press articles, public relations – influence on Hungarian building laws

Presentation SOLANOVA, January 2003 Department of Building Energetics and Service Systems Department of Energetics and Energy Systems Budapest University of Tecnology and Economics Center for Environmental Systems Research University of Kassel SOLANOVA - The Consortium Hungary – Budapest University of Technology and Economics – Fiorentini (Solar) – District Heating Company and Sziget Office, Dunaujvaros – Energy Centre Austria – Internorm (Windows) Germany – University of Kassel – Passive House Institute, Innovatec

9. Presentation SOLANOVA, January 2003 Department of Building Energetics and Service Systems Department of Energetics and Energy Systems Budapest University of Tecnology and Economics Center for Environmental Systems Research University of Kassel What qualifies a passive house No conventional heating system Extremely reduced heat losses – Super insulation of walls, roofs... (20-30 cm) – Super glazing (u < 0.8 W/(m 2 K) – Controlled ventilation Maximum heating power: 10 W/m 2 Transmission coefficients u < 0.15 W/(m 2 K) Annual heat consumption < 15 kWh/m 2

10. Presentation SOLANOVA, January 2003 Department of Building Energetics and Service Systems Department of Energetics and Energy Systems Budapest University of Tecnology and Economics Center for Environmental Systems Research University of Kassel Planned retrofit measures High level external thermal insulation (20 cm) Installation of high thermal performance windows (U=0.8 W/m 2 K) Balanced ventilation system with heat recovery Solar collectors (appr. 140 m 2 ) Controled heating system if needed
