The luxurious Four Seasons Hotel in Abu Dhabi is placed next to the city’s new financial district, Sowwah Square, in Al Maryah Island (Island to be a new city centre). The hotel is located in a 10 600 sq/m site, having 34 floors, which round up to 200 hotel rooms and 120 apartments. The building’s external aluminium and glass shading were developed to help mitigate solar radiation. To guarantee the building’s protection against the harsh surrounding environmental conditions and to assure the quality of its indoor air, Effisus Ecofacade was applied. The membrane was used to seal the building’s façade connections, such as windows, metal frames, and more.
