The NZEB Open Doors Days campaign wants to give hands-on-experience with nearly zero energy buildings (NZEB) to the broad public and public authorities and to convince them the EPBD (European Energy Performance Directive) challenge can be met.
The recast of the EPBD directive (2010/31/EU) will challenge European citizens and public authorities. By 1 January 2019 every new public building will have to comply with the nearly zero energy building requirements, all other new buildings will comply with the new requirements two years later.
We organised doors open days in 10 EU countries in November 2013 and 2014. During these events both public and private actors could visit new and refurbished houses and public buildings, highlighting nearly zero energy standards. 1,440 buildings were exhibited.
The central idea of a Doors Open Day is that visitors get non-commercial hands-on-experience with nearly zero energy buildings. During a visit, you got to know the living, working and building experiences of the owners and builders. We made the general public aware of the technical possibilities of current building and refurbishment technologies and future requirements regarding NZB building standard.
We gave thorough information to the broad public and potential builders and public authorities about NZB’s via brochures, media reports and a dedicated web platform. We recruited 1,440 buildings that were exhibited. We reached an audience of 25,870 visitors in the two ‘Doors Open Days’ campaigns of 2013 and 2014 (houses and public buildings). The project convinced 76,5% of the visitors to implement presented good practices.
Each partner set up a national web platform to acquire buildings for the Open Doors Days, to organise subscriptions and to give both general and specific information on NZEB’s and the EPBD requirements. We showed the EU challenge and many inspiring examples of NZEB’s. We developed a set of mini-documentaries showing energy efficient solutions from all over Europe and visualising the common European goal of the EPBD.
Five international visits of carefully selected opinion makers to NZEB’s were organised between countries. We disseminated their experiences broadly.
In 1998 BBL-Bond Beter Leefmilieu developed in Belgium a concept of “Ecobouwers Opendeur” to inspire builders and home owners to build and renovate their houses to a high energy standard. With more than 40,000 visitors over the past 16 years Ecobouwers Opendeur has built a steady reputation as the biggest independent and non-commercial open house event in Flanders.
Only in 2010 more than 3,000 visitors were welcomed at 130 houses and 21 office buildings. Whereas the campaign web platform www.ecobouwers.be attracted more than 1.000.000 visitors. It is expected that the campaign will have a high impact on the decision makers regarding energy performance of buildings be it new one or those under refurbishment. 40.4% of the visitors had building plans; 24.5% had renovation plans and 21.6% were right in the middle of their construction/renovation works. 88% of respondents considered campaign and valuable and informative.
“Ecobouwers Opendeur” scaled up its success under the framework of the Intelligent Energy – Europe program. With BBL leadership and guidance, campaigns promoting Nearly Zero Energy Buildings was launched in 9 new countries under the common name of NZB2021 ‘Doors Open Days’.
