The Gran Rubina project includes the design of a master plan for a total of 150.000m2 in central Jakarta for the developer, PT. Triyasa Propertindo.
The plan focuses heavily on sustainable design solutions, particularly social sustainability and low energy usage. Located on one of the few remaining green field sites in the heavily populated city, the idea has been to preserve public access around the buildings. Functions such as car parking and retail have been buried in a terraced “hill” with access from the perimeter, allowing free pedestrian flow between the buildings.
The buildings themselves have been organised in a staggered layout preserving views but minimising soar gain through their orientation. A series of deep horizontal bands and vertical glass fins ensure shading of the façade. Sky gardens located at various intervals up the buildings are similarly screened taking the traditional Indonesian rattan as inspiration for creating privacy but ensuring natural ventilation.
AG5 and PDW are working together on the first 26 storey, 40,000m2 building as a pilot project involving BIM and energy simulations.
