Energy Agency Bonn: Bonn house renovators are not alone

A barrier to many energy-efficiency upgrade projects: After the initial energy consultation and making the decision to renovate, qualified service providers and consultants are difficult to find. The energy efficiency partner system launby Bonner Energie Agentur (BEA – Bonn Energy Agency) provides a solution to this – with a compiled list of quality assured service providers.

The energy efficiency partner scheme by Bonner Energie Agentur (BEA) helps house and apartment owners to find qualified service providers for the implementation of energy efficiency measures and the use of renewable energies in the area of construction and renovation.

For this purpose, the basic model for the eza partners from the Allgäu region (eza: Energie- und Umweltzentrum Allgäu – Energy and Environment Centre) was used and further developed with local stakeholders such as Bonn/Rhein-Sieg Guild of Craftsmen as well as trade guilds and planning associations.

Engine for progress:

  • presentation of all service providers at a glance
  • quality assurance for consulting and implementation
  • exchange of information between various trades and disciplines / craftsmen and planners made fit for energy efficiency
  • current industry overview
  • BEA is addressing Bonn's high potential
  • an exemplary model for other cities and municipalities

Thus, the appropriate craft businesses, energy consultancies and planning offices can be certified for energy-efficient construction and renovation. The reviewed companies are recommended by BEA during energy consultations and listed on the Internet. The local NRW consumer association advice centres also refer to BEA lists. The renovators gladly accept these recommendations: Around 30 per cent of those consulted who engage a craftsman used the contacts on this "Efficiency Partner List".

Quality Renovation

In order to qualify for the list, the companies must undertake to comply with the "energy code" and the general quality standards of the system, provide evidence of having attended a four-day training course within the last year, submit proof of ongoing practices and further training as well as attending at least two partner days per year. The events organised by BEA provide the certified planners, consultants and craftsmen with information on new rules, standards and techniques.

Particular value is placed on the exchange of information between different trades and disciplines: The more efficient a building is, the more complex it usually is. That is why BEA places particular value on explaining the 'Gesamtsystem Haus' (holistic house system) to the trades and helps them to look at neighbouring trades. This opportunity to take a broader view helps to implement quality renovations as well as to reach energy-saving targets. According to the consulting company Prognos, BEA consultations save 310 tonnes of CO2 per year.

Potential for the City

The city launched Bonner Energie Agentur in 2011. In 2012, the agency was founded as an association in order to promote climate protection at local level, especially in the fields of energy-efficient construction and renovation and the use of renewable energies. In 2014, the City of Bonn was awarded a prize in the "cooperation" category of the "Municipal Climate Protection" competition for this commitment.

Bonn has great potential regarding energy-saving renovation: Around 120,000 residential units (about 75 per cent of the homes) were built before 1978. Energy efficiency measures can achieve a great deal.

"If politicians and government in Bonn make a commitment to reduce CO2 and enter into a cooperation with business, this creates a win-win situation for all involved. The energy efficiency partner system by Bonner Energie Agentur is a perfect example of how such an unusual project can be a model for success."
