Technical background of the Hungarian Green Investment Scheme

Tamás Csoknyai

Budapest University of Technology and Economics

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 sectorNEP:

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 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 fieldsA) 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 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

label reached Market (energy expert) will select the most

efficient measures The whole building must reach the target, but not

the rules of Passivhaus Institut Darmstadt

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 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 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
