The following information has been gathered as part of the CONCERTO Premium policy research.
Benefits of CONCERTO:
Key benefits:
Advance to a climatic protection region, to foster local energy supply and to implement energy efficiency measures on short-term. Achieve the self-sustaining energy system on the long-run.
Skill development:
6 installers and 2 representatives of property management have been involved in training.
Local economic effects:
Local investment: Roughly 50%.
Barriers encountered:
Legal barriers:
For retrofitting of apartment buildings a majority decision of the residents is necessary and might be time consuming. The thermal insulation of two facades of one apartment building were not completed, because the insulation touch the property of the neighbour. The neighbour wanted to go to court in case it had been done. To achieve a majority decision of the residents an extensive information process is necessary. Moreover the residents have to be involved in all decisions concerning retrofitting.
Technical barriers:
Lack of training in the sector especially for PV installers. Training courses have been established.
Economic barriers:
Costs for large wood gas CHPs were too high.
Social barriers:
Opposition to biomass heating plant and biogas plant. No electrician educated and experienced in installing photovoltaics. Fine dust filters, information to public, further negotiations. Amendment request: scientific assessment of wood gas CHP and existing biomass-CHP. Seminars for electricians how to install PV. Installation of PV-plants of public buildings by ATB, in cooperation with local roofer.
Administrative barriers:
Planned measures need an in-depth analysis through the communal building department. Delay in environmental statement due to public opposition. Improved political consensus.
Success factors identified:
Technical success factors:
The technologies in HOLISTIC fell into two categories – renewables and energy efficiency. In general terms, the renewables did not lived up to expectations, whereas the energy efficiency measures did generally delivered what was required of them.
Social success factors:
Different social groups could be addressed such as citizens interested in participation models and environmental matters, Christian groups.
Business models used:
Investigations came from the town council budget, from contributing third parties and home owners. In particular cases like Kindergarten Energy Performance Contracting (EPC) has been used.
Legacy – follow-on projects:
PV participation models with a capacity of 400kWp are envisaged.
