The entire Aubevoye wastewater treatment plant responds to an innovative HQE® approach, proposing a bioclimatic timber frame construction building made of Douglas fir class 4, combined with natural and high-performance materials, enabling healthy, comfortable and sustainable construction. , with positive energy by an integrated photovoltaic roof at the heart of a remarkable site. The building is oriented on a North-South axis allowing to benefit from an optimal sunshine during the period of the winter and during the summer the heat is dissipated by the dual-flow ventilation and devices on the roof of solar shading. The whole building is part of a green setting. Landscaping is offered through different landscape units that make up an eco-landscape throughout the site, supporting a walkway integrated into the educational pathway and promoting the development of biodiversity.
Sustainable development approach of the project owner
The client's wish was particularly focused on the following environmental issues:
- Creation of a bioclimatic building with wood frame and accessible to the public;
- Integration of buildings and equipment into the environment;
- The use of materials easily recyclable;
- Use of photovoltaic panels;
- Integration of an anaerobic digestion unit within the building for the valorization of the heat network and the use of the energies produced to supply the equipment of the municipality;
- The quality of life of the operating staff and residents by taking priority into consideration of olfactory and acoustic comfort conditions;
- The acquisition of a new attitude, more responsible vis-à-vis the resources especially the water of the air of energy.
- Special attention for the restoration of biodiversity on site.

Building users opinion
The occupants are fully satisfied with the thermal comfort inside the building, the sanitary quality of the interior spaces, the visual comfort, the quality of the indoor air, the quality of the natural light inside the spaces. of work as well as acoustic comfort.
If you had to do it again?
We would have redone the same project by integrating all aspects that will make this project a reference from an eco-construction point of view.

Product
The Pine
Durapin
Piveteau-Bois
http://www.piveteaubois.com/fr/Structural work / Structure - Masonry - Facade
Frame made of treated pinewood class 4, from sustainably managed European forests, ensuring dimensional stability, strength, mechanical resistance, adapted to a warm and humid environment, and resistant to insects, termites and rot.
Product very well accepted by all the stakeholders of the project, and which allowed a clean (dry) and fast construction site for the assembly of the whole structure.

Life Cycle Analysis
Reasons for participating in the competition(s)
L’ensemble de la station d’épuration d’Aubevoye répond à une démarche HQE® innovante, proposant un bâtiment d’exploitation bioclimatique en ossature bois en pin douglas classe 4, associée aux matériaux naturels et performants permettant une construction saine, confortable et pérenne, à énergie positive par une toiture photovoltaïque intégrée au cœur d’un site remarquable.
Le bâtiment est orienté sur un axe nord-Sud permettant de bénéficier d’un ensoleillement optimal pendant la période de l'hiver et pendant l'été la chaleur est dissipée par la ventilation double flux et aux dispositifs en toiture de brise-soleil. La bâtiment intègre une station de méthanisation qui transforme les boues issues de la station en biogaz et réutilisées sous forme d'énergie, approvisionnant le réseau de chaleur de bâtiments publics.
L'ensemble du bâtiment s'intègre dans un écrin végétal. L'aménagement paysager se décline aux travers différentes entités paysagères constituant sur l'ensemble du site un éco-paysage, support d'une promenade intégrée au parcours pédagogique et favorisant le développement de la biodiversité. Le caractère environnemental du bâtiment est indissociable de son insertion dans l'écrin vert constitué de l'aménagement paysager, mais aussi de la zone humide d'acheminement des eaux traitées jusqu'au point de rejet dans le milieu naturel.
