Sustainable development approach of the project owner
The city of Amiens wanted to refurbish the kindergarden of Michel Ange, by making the first positive energy refurbishment on the French territory. The goal is even more ambitious than the occupants are young children, whose comfort can not be neglected.Rabot Dutilleul Construction Company has joined forces with SECA ENVIRONMENT agency, so as to offer to the city of Amiens an overall technical solution, incorporating both technical and structural constraints of a refurbishment, but also ambitious energy objectives.
The result: energy efficiency and sustainability beyond the initial specifications, in accordance with the budget.
Architectural description
Architect and general contractor- the city of Amiens.The goal was to reach the BEPOS level for a very major refurbishment of the building, without much changes in the visual aspect of the building, excepting the roof.
Building users opinion
For the city of Amiens, the refurbishment of the kindergarten Michel Ange represents different challenges. First, a social issue, because this project helps to make children but also their parents, and more generally the educational sector, more aware of the energy saving needs.
The economic aspect is also important with energy savings estimated at 17,000 € per year for the school. The last issue is of course environmental; this renovation project is a part of a sustainable development policy and of the objective of reducing greenhouse gas emissions initiated by Amiens Métropole, seen in particular in this school, through the production of electricity using photovoltaic panels on the roof.
In the construction phase, the use of a general contractor was appropriate to ensure the overall goal. By high energy performances, Rabot Dutilleul Construction has committed to ensure the respect of the air tightness of the building envelope. To preserve this air tightness during the future maintenance operations, data sheets have been developed to raise awareness of the procedures to avoid any deterioration of the concept.
After over a year of functioning, if the savings are real, the expected results are somewhat skewed because of the creation of a recreational centre inside the school which had not been included in the simulations before work.
The observations also show that further efforts are required in terms of awareness and user education which behavior can lead to overconsumption. In conclusion, the energy refurbishment of the kindergarten Michel Ange into a positive energy building - a first case in Picardy - is a most successful experiment of Amiens Métropole, whose profits may be valued on future construction or renovation projects .
