Oreintation and Building Design

The site is located at the frontage of Persiaran Barat, facing the Federal Highway. The building overlooks the highway, occupying PJ Sentral Garden City’s western boundary and is directly accessible from the Jalan Timur-Jalan Utara ring road as well as the Taman Jaya LRT Station. The building has a northwest orientation with a surface area to GFA ratio of 32.55 per cent. The spatial organisation adopts the ‘island plan’ in which the core of the building is located in the middle and the office areas surround the perimeter of the glazing to optimise view and daylighting.

The iconic lozenge shape of the building acts mainly as a symbol of the company brand. Moreover, the natural geometry of the vertical lozenge ensures that the floor plate reduces in size as it goes to the top of the building. This reduces the roof heat transfer as it has the smallest floor plate area. In terms of façade, the surface takes on a folding texture to give it a dynamic architectural profile. This is also done in order to reduce direct heat gain and glare by introducing angles on all surface of the glazing

Use of Wind

Natural ventilation is utilised for all podium car park areas and the covered cafeteria on the podium deck. For car park, adequate perimeter opening is allowed in order to obtain the minimum 10 per cent surface-opening-to-floorarea ratio required for natural ventilation.

Natural Daylighting & View Optimisation

Natural daylighting, together with the façade’s solar performance, was carefully balanced as it was the first few office buildings in Malaysia to have floor-to-ceiling glazing.

Materials & Shading Materials

With no external shading devices, it means that direct solar penetration would be high, and thermal transfer would skyrocket. To address this, and also to be able to minimise the size of air-conditioning devices, the selection of glass type is crucial.

Construction & Materials

During construction, a recycling regimen was adopted via segregation of materials, implemented on each floor with accessibility from circulation zones. Aluminium off-form casting was used for at least 23 typical tower levels to limit material wastage and the reuse of concrete moulds.
