Côte d'Ivoire, a West African country, is officially named "Ivory Coast" in French, but the government requires the international community to use a transliteration of the name. 

Regarding the user's query about "ERV ventilation system" (energy recovery ventilation system), the current search results do not directly mention specific locations or 

buildings in Côte d'Ivoire where this system has been applied. However, the following general design principles for ventilation systems can be used as a reference:

Ventilation System Components

A typical system includes fans, ducts, air inlets, filters, and other equipment. The air inlet should be located in a clean air area, while the exhaust should be downwind of 

the prevailing wind direction and maintain a horizontal distance of 10 meters or more, or a vertical height difference of 3 meters or more, from the air inlet.

Installation Specifications

Duct hangers should be evenly spaced, and additional brackets must be installed at elbows and valves.

Flange bolt threading should align with the airflow, and the gasket thickness of clean system flanges should be 5mm or more.

For specific information on the application of ERV systems in Côte d'Ivoire, it is recommended to further consult the country's building codes or project examples.
