Positive Energy Building Label, Effinergie 2013 Use of BIM
BIM : The project was led from design stage in BIM, allowing free architectural expression, respecting technical and economic feasibility. Since the envelope was industrialised and handled by the companies of the Group, each envelope related trade provided a BIM model from 3D modeling software. This peculiarity of operation allows us to give life to the project from the design stage to the construction stagen the form of digital models, the initial architectural models being replaced by operation models in the process.
Positive Energy Building :
The other particularity of this project is the use of electricity as heating vector and as a production of hot water. During the phase of architectural design competition, the owner wanted to connect the project to the district heating network of the city of Rezé. However, thanks to our strong experience on other operations, we have been able to assert our expertise with the client, to overcome the current regulations, and letting go of the heating network. The owner wished therefore to orient its project toward energy efficiency, and to obtain the Positive Energy Building label. The project, meeting the demands of the city in terms of architectural integration (proximity to the Radiant City by Le Corbusier), was treating the fifth façade, treated with photovoltaic panels. We have combined the wishes of the contracting authority and those of the city in order to insert our project in the existing urban fabric (training center and shelter for young workers building) as best as we could.
