Technical background of the hungarian green investment scheme

Technical background of the Hungarian Green Investment Scheme

Tamás Csoknyai

Budapest University of Technology and Economics


Main considerations

Main considerations

  • Efficiency aspects: highest CO2 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 CO2 mitigation and energy saving should be registered;

  • Only residential and public buildings are subject of support.


Other national support programs in the building sector

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


Arguments for complex projects

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


Supported fields

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


Complex renovations

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


Technical background of the hungarian green investment scheme

Category C


Energy efficient new buildings

Passive house

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


Individual measures not supported by other national support programs

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


Technical factsheets

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


Evaluation and control

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


Conclusions

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
