CONSTRUCTION FIXINGS Sustainable anchoring
The European Consortium of Anchors Producers is part of a winning project for the Seventh Framework Programme for research and technological development (FP7) of the European Union.
the 1960s and 1970s, you know how little attention was given at that time to the energy efficiency, starting from the poor thermal insulation. On the other side, a strong and massive intervention on an old building could have social consequences. Just think about the many sad efforts that were done to renovate the façades of whole quarters in the countries of the former Eastern bloc, which then appeared even sadder and nobody felt at home. Also it could cause problems for sustainability, for which the social aspect is just one of its components.

“ The main objective of EASEE is to give to construction SMEs a ‘Toolkit’ to reduce energy demand, while minimising the impact on occupants during the retrofitting of existing buildings.”
When interventions are made on existing buildings, anchors
are the most sustainable way to intervene. For example, on a façade when a huge intervention is concentrated on a few fixing points. Using anchors on a façade brings advantages for energy, costs, and it implies a less invasive intervention and, therefore, easier possible dismantling of materials for their recycling or disposal. All this favourably affects the sustainability balance. For such reason, anchors are an integral part of a winning
European project, that faces the issue of developing an energy efficient envelope retrofitting of multi-storey and multi-owner buildings built before 1975. The project is called EASEE – “Envelope Approach to improve
Sustainability and Energy efficiency in Existing multi-storey and multi-owner residential buildings”. It is formed by a well balanced group of multinationals and SMEs, coming from all across Europe. ECAP, the European Consortium of Anchors Producers, is
ne of the biggest challenges in the European construction world, is to adapt existing buildings to the European regulations on energy. Indeed, if you have been living, like I have, in multi-owner buildings of
one of the partners. Its role is to support in the standardisation issues, in the selection of best anchoring systems for the retrofitting, and in the dissemination/training to SME installers. The main objective of EASEE is to give to construction SMEs a
‘Toolkit’ to reduce energy demand, while minimising the impact on occupants during the retrofitting of existing buildings. There is a strong need for the development of new, flexible and easy-to-apply solutions for the envelope retrofitting while keeping the original appearance of the façade. EASEE wants to preserve the original aspect of the façade,
so a combination of modular prefabricated components is used, which give the final appearance without additional finishing on site:
• Solution for the external façade: modular pre-fabricated components that have the final appearance without requiring wet finishing and with scaffolding-free installation.
• Novel loose fillers for the cavity wall. • Solutions for the inner walls. Proper combination of textile membranes, plasters and coatings.
And finally…how do you fix all that? ECAP members and a big German anchoring systems company are involved in this challenge: to conceive anchoring systems according to the aim of the project, whose duration is estimated to be forty eight months starting from January 2012. Other partners of the projects are producers of insulating plasters and renderings, prefabricated façade panels, advanced technical and protective textiles, insulating materials, software solutions, reconfigurable moulding, and construction companies. Research institutions experienced on energy efficiency and energy performances are from Switzerland, Italy, Belgium and Greece. One full scale demo building will be retrofitted with the
proposed method, from assessment of the starting conditions to the installation of the modular elements and to the monitoring of performance after retrofitting. A social housing in the Milan, Italy, area has been chosen as a demonstration site.
