1. Technical background of the Hungarian Green Investment Scheme Tamás Csoknyai Budapest University of Technology and Economics

2. Main considerations  Efficiency aspects: highest CO 2 mitigation – investment costs ratio;  PILOT PROJECTS: MULTIPLICATION EFFECT  Technical feasibility aspects;  International trends (BAT and supporting schemes);  Other corresponding national support programs  Demonstration aspects;  EU requirements and related Hungarian legal documents (2002/91/EC directive, 7/2006 (V.24.) TNM, 2006/32/EC directive, National Energy Efficiency Action Plan, etc.);  Attractive program and simple procedure  Definite technical requirements;  Definite determination of grant;  Efficient control procedure;  More efficient investments should receive more support;  Resulted CO 2 mitigation and energy saving should be registered;  Only residential and public buildings are subject of support.

3. Other national support programs in the building sector NEP: Mainly masonary constructions Individual applicants Focus on individual measures Retrofit actions and renewable energy No new buildings Low intensity of support (15-18-20-25%) Limited budget Panel programme: Buildings made with industrialised technology Focus on individual measures Only whole buildings Retrofit actions (not exclusively energy) and renewable energy Reasonable intensity of support (30%) Limited budget EEOP, ROP: Non-residential sector Large projects

4. Arguments for complex projects  Fabric protection: exchange of windows, controlable heating  Energy aspects: Upgrade of the building envelope – not udjusted heating system Modernisation of the heating system – upgrade of the building envelope later – adjustment of the heating system again Efficient boilers work with low temperature – energy efficient house needed Balanced ventilation – air tightness Sunspaces – thermal insulation  Other aspects: Investment cost of renewable energy systems in an efficient and an inefficient building Construction costs of a complex renovation lower Inconviniencies for occupants less Open burners – air tightness – ventilation system No conflict with other support programs

5. Supported fields A) Complex projects Complex renovations Energy efficient new buildings B) Individual measures not supported by other national support programs: Solar protection measures Balanced ventilation with heat recovery Glazed loggias Renewable energy systems (?):  Solar DHW-production  Heat pumps  Biomass burners

6. Complex renovations  Awarding system  Based on EPBD  Target energy label: C, B, A, A+  Support depends on the target label in % of investment costs  Calculation according to EPBD (7/2006 (V.24.) TNM Ministrial decree)  Any combination of measures acceptable if target label reached  Market (energy expert) will select the most efficient measures  The whole building must reach the target, but not all the occupants need to participate

7. Category C

8. Energy efficient new buildings  Awarding system  Based on EPBD  Target energy label: B, A, A+, passive house  Fix support in function of target label  Calculation according to EPBD (7/2006 (V.24.) TNM Ministrial decree) except passive house  Any combination of measures acceptable if target label reached  Market (energy expert) will select the most efficient measures  The whole building must reach the target, but not all the occupants need to participate  Passive house certification process according to the rules of Passivhaus Institut Darmstadt Passive house

9. Individual measures not supported by other national support programs Solar protection measures Balanced ventilation with heat recovery Glazed loggias Renewable energy systems (?):  Solar DHW-production  Heat pumps  Biomass burners

10. Technical factsheets  Technical guidelines for applicants about frequent individual measures: Side effects Recommended combinations with other measures Risks and solutions Technical requirements Recommendations, privileged solutions  Guidelines for the evaluators in case of questionnable applications

11. Evaluation and control  Independent energy experts guarantee the technical quality on the applicant side  Other independent energy experts guarantee the technical quality on the evaluation side  The rules of the calculation is fixed in the 7/2006 (V.24) Ministerial Decree – well known by experts  Energy bills need to be preserved for occasional control  Different, but internationnally accepted procedure for passive houses

12. Conclusions  Complex demonstration projects  multiplication effect  Limited types of individual measures  Renovations and energy efficient new buildings  Passive houses  Awarding system  Efficient use of grant for each individual project generated by the labelling system  Technical factsheets
