ABSTRACT
From the previous LEHR-project, it became clear that many retrofit projects are executed in a very fragmented way: many actors do a certain part of the works, without cooperation or coordination. Sometimes, there is a lack of attention for works that have been executed already, or the works that have to be executed afterwards are not kept in mind. This is however very important, especially when striving for nearly zero energy buildings in housing.
It is desirable that every activity executed in a renovation, is integrated in a global concept, and thus takes into account the works executed earlier and afterwards in the process chain.
The presented research was executed during the One-Stop-Shop-project. It maps these interactions for thorough, nearly-zero-energy, retrofit projects, using a structured approach (matrix), a process analysis and contacts with frontrunners in the field. An overview is given of the most important and critical attention points during design and execution, when different actors intervene in the same project.
This overview allows for the development of solutions. These can be a more integrated execution of the works and/or the application of innovative technology. A selection of solutions is presented.
