Located on the crest of the ravine Touza near the old mill on the heights of Fort de France, the house opens on two levels with trade winds. In the Caribbean climate, which has the particularity of being hot and humid, where only ventilation can naturally refresh, the elevated situation is an asset.
Designed for the Agence Française de Développement (AFD) agents on a delegation in Martinique, the Villa Vieux Moulin has sought to reduce its ecological footprint as much as possible while aiming for energy autonomy . Located on a steep ground, the house has been positioned to benefit as much as possible from the garden offering a panorama mastered. The surrounding plantations help refresh the atmosphere and hygrothermal comfort .
The space is divided into two distinct parts: A day on the ground floor and a night party on the floor, so that a protocol life can take place regardless of family life. The living room on the ground floor is open to the kitchen. The ground floor is also the place of the technical spaces of the house. A door to the kitchen leads to the cellar, laundry and garage. Upstairs, four bedrooms, one with en-suite bathroom, open onto an interior north-facing walkway. To the south, the rooms overlook a shared terrace overlooking the garden. The layout provides on the ground floor the possibility of making a room and an additional bathroom to accommodate, if necessary, a disabled agent.
The bioclimatic operation reinterprets the traditional principles of Creole architecture that channel the flow of wind into the roof and the living spaces to ensure its refreshment. The large façades equipped with glazed nacos make it possible to control the through ventilation and air brewers come into operation in case of absence of wind. The metal structure designed to withstand cyclones and seismic jolts that threaten the site can limit unnecessary inertial masses that would harm the comfort of the occupants, as evidenced by the thermodynamic simulations carried out by the office of study TRIBE. The sun breezes put the windows north and south away from direct radiation, the sun oscillating on both sides of the vertical in this latitude. Two solar captures, thermal for domestic hot water and photovoltaic for electricity allow to move towards energy autonomy and level with the frequent power cuts of the island.
The problem posed by AFD's program consisted of the realization of a villa naturally refreshed but which is air-conditioned in order to be able to receive people of fragile health . In order to satisfy these two seemingly contradictory requests on the bioclimatic level, air conditioners were installed in the rooms but coupled to a wall shelf installed in the living room which allows to measure in real time the consumption generated by the occupant . it is empowered and domestic consumption reduced.
Thus equipped with a software specially developed by Martinique company Windéo Green future in collaboration with XLGD architectures , the villa is constantly susceptible to calibration of consumption. This software that also includes the "logbook" of the villa allows to optimize maintenance and consider successive improvements in all the knowledge of both the comfort of use and the ecological footprint.
In 2018, the villa Vieux Moulin has been certified NF HQE housing by Cerqual.
Sustainable development approach of the project owner
The French Development Agency (AFD) intervenes in the world especially to fight against poverty and support economic growth. These actions led her to build up a real estate portfolio in each of the countries concerned. To date, it includes more than 360 well distributed in more than seventy countries of Africa, South America, Asia or the Caribbean. An important park therefore, that it has recently undertaken to renovate given its great age.
Architectural description
The Old Mill Villa
Located on the crest of the ravine Touza near the old mill on the heights of Fort de France, the house opens on two levels with trade winds. In the Caribbean climate, which has the particularity of being hot and humid, where only ventilation can naturally refresh, the elevated situation is an asset.
Conceived for the attention of Agence Française de Développement (AFD) agents on a delegation in Martinique, the Villa Vieux Moulin has sought to reduce its ecological footprint as much as possible while aiming for energy autonomy. Located on a terrain infort cant, the house has been positioned to benefit from the garden in its greatest length offering a panorama mastered. The surrounding plantations help refreshing the atmosphere and hygrothermal comfort.
The space is divided into two distinct parts: A day on the ground floor and a night party on the floor, so that a protocol life can take place regardless of family life. The living room on the ground floor is open to the kitchen. The ground floor is also the place of the technical spaces of the house. A door to the kitchen leads to the cellar, laundry and garage. Upstairs, four bedrooms, one with en-suite bathroom, open onto an interior north-facing walkway. To the south, the rooms overlook a shared terrace overlooking the garden. The layout provides on the ground floor the possibility of making a room and an additional bathroom to accommodate, if necessary, a disabled agent.
The bioclimatic operation reinterprets the traditional principles of Creole architecture that channel the flow of wind into the roof and the living spaces to ensure its refreshment. The large façades equipped with glazed nacos make it possible to control the through ventilation and air brewers come into operation in case of absence of wind. The metal structure designed to withstand cyclones and seismic jolts that threaten the site can limit unnecessary inertial masses that would harm the comfort of the occupants, as evidenced by the thermodynamic simulations carried out by the odesign office TRIBE.

In order to satisfy these two seemingly contradictory requests on the bioclimatic level, air conditioners have been installed in the rooms but coupled to a wall-mounted tablet installed in the living room which makes it possible to measure in real time the consumption generated by the occupant.

Building users opinion
Very well
If you had to do it again?
On this site in particular, a major difficulty of earthworks that we chose to face to release the sight and the space of the garden. An extra cost that was worth it.
