*인터렉티브 외피 시스템 [ aedas ] al bahar towers

인터렉티브 스킨 시스템을 제안합니다.

외부로 부터 유입되는 직사광선을 효과적으로 차단함으로써

내부환경을 쾌적하게 유지하도록 도와주는 스킨 시스템은 전통적인 이슬람

문양을 현대적인 디자인코드로 변환, 파라메트릭화한 디자인 결과물을 보여줍니다.

'마시라비야'라고 불리우는 이슬람 전통창의 격자패턴은 다양한 방향으로 확장 가능한

헥사곤 형태의 패턴으로 재구성되어 외부 태양빛을 차단합니다.

이로써 내부 열에너지의 과부하 현상을 줄임으로써 에너지 소비효율면에서도

150% 이상의 효과를 가져 오게 됩니다.

international practice aedas is nearing completion of the 'al bahar towers' for the abu dhabi investment council headquarters in abu dhabi, that utilize what is perhaps the largest and most advanced interactive sun-shading skin system. the two 25-storey office towers are parametrically designed based on islamic geometric mosaics, using the tessellation of simple shapes to drive the structure. the cylindrical forms maximize volume and floor-to-wall area while offering views in all directions, unfortunately however, this also opens the interior to a very large solar gain factor which is a substantial problem in the extreme local climates.

reinterpreting the traditional wood-lattice screens called 'mashrabiya' using today's technological abilities resulted in an outer skin system of triangular screens arranged in a series of scalable hexagons fold up to create a solid solar barrier. each of the 1000 panels is connected to a linear actuator which enables it to function in response to the position of the sun, effectively reducing heat gain and glare by 50% while giving islamic vernacular a contemporary representation. the intelligent facade, together with solar thermal panels for hot-water heating and photovoltaic panels on the roof, minimize the need for internal lighting and cooling, altogether reducing total carbon dioxide emissions by over 1750 tons per year.
