Energy-intensive building

General information

This office building located in the heart of Nantes It is certified HQE (excellent) and labelled BBC Effinergie (low consuption buildings, according to the French thermic regulation RT 2005). Its particularity is to offer BBC performance without resorting to renewable energy, relying heavily on its eco-design (compactness, orientation, performance systems ...) and remaining completely in the price of the market.

Its location (less than 5 minutes walk from the train station) and travel Plan also make a building that is fully involved in controlling the impact of the city of Nantes.

Sustainable development approach of the project owner

Triple certification Iso 9001, Iso 14001, OHSAS 18001

Architectural description

The building is very compact, with office floors up to 23 m deep. Slightly shifted its orientation from north-south axis allows each façade lighting even briefly, depending on the time and season. Although compact and a refined architecture, the building is remarkably well integrated into the urban fabric as its varied épannelage lets light for the benefit of residents and pedestrians. Vertical windows and "full height" give local brightness pleasant, and the large thickness of clear tables diffuse light without glare. Blinds and white wide blades act as light shelves.

Building users opinion

The energy performance of the building brings new constraints sometimes destabilizing (you can not adjust the heat as we would wish, but the instructions are adjustable strictly regulated).

In addition, the local light and very comfortable giving a feeling of luxury not ostentatious, which is certainly not for anything in the speed with which the lots were sold.
