A Maison Cité 2025

The construction of this house is a part of the  Cité internationale’s Cité 2025 development plan. The Maison de l’Île-de-France is the first collective accommodation building that is energy positive using 100% solar and collection realised in France. It won the Green Solutions Award 2018 international prize within the COP 24 category in Poland. It is the result of a shared desire between the Île-de-France region and the Cité internationale to invest in ecologically technical future. It allows the Cité internationale to be at the forefront of collective construction that isn’t harmful to the environment.

The Maison de l’Île-de-France is managed by the Fondation nationale Cité internationale universitaire de Paris.

Architecture that privileges resident comfort

The house, which has 142 rooms, privileges communal space, notably with a large double-height multipurpose room that opens up to the park. Every floor has 23 spacious rooms which are furnished and equipped with a shower and toilets, all of which are handicap accessible; they are spread out along a double corridor that is elongated by a north-facing communal kitchen.


A unique geometry

Realised by the architecture agency ANMA, the building consists of 8 floors, is compact and geometrically unique with a triangular shape on the park side, and is more open on the peripheral side to make a large partition that captures solar energy. The south façade is exposed to the road and is used to create an acoustic barrier, its orientation also allows solar panels to be installed.

An environmentally innovative project

Designed to significantly reduce energy consumption and greenhouse gas emission, the Maison de l’Île-de-France reasserts the Cité internationale’s ecological ambitions.

In accordance with regional guidelines and the City of Paris’ Climate Plan, and thanks to the innovative techniques available, the house aims for environmental exemplariness. The Maison de l’Île-de-France benefits from a true solar power plant that guarantees 75% of its thermal needs. Solar tubes heat a total volume of 156 mof water that is distributed into two premade tanks which are 15m tall and hold 110 m3 and were developed by the DEERNS design office. The accumulated heat in the tanks is produced thanks to the thermal solar tubes installed on the south-facing façade of the building. This allows it to produce heating and clean water and to also store the excess which can be used in the winter months. In parallel with this innovative system, the building’s electricity production is provided by the photovoltaic panels on the roof and on the slope of the south-facing façade.

The house was awarded the International Green Solutions Award 2018 at the COP 24 in Poland.
