The whole of the enclosed accommodation is served by a continuous inner ring of single-loaded circulation, which encircles and views the elliptical atrium. Equally, the office space can view inwards across the circulation, or outwards from the periphery of the essentially 'thin' plan-form. This arrangement also maximises the provision of extensive natural-light and affords a first-class working environment for all occupants.

Detail studies of the sunscreen louvre banks and solar filters determine the appropriate level of solar protection and modify the daylight, while minimising heat gain and reducing energy costs.

The final major element is the over-sailing 'free' sculptural roof structure of the elliptical atrium, which is designed as a transparent umbrella rain-screen, allowing daylight to penetrate to the garden oasis beneath its sheltering presence. At the same time, the cantilevered outriggers of the roof-umbrella are intended to shield extensive roof-gardens.

What is clearly evidenced in this project is the well-rehearsed repertoire of Veang's passive low-energy building agenda; all the elements are present, from the naturally ventilated lift-core lobbies to the skycourt gardens and partially open circulation. To this basic framework he has added the 'big idea' of the sheltered atrium and the elliptical geometry. The whole is gathered together into a sustainable building in response to the United Nations' agenda and towards a responsible 21st century architecture. For instance, in this case (as with all others that follow) Yeang has incorporated an Embodied Energy Study of the major building fabric - an aspect of his proposition that future design quality will be based upon knowledge - a substantiation of facts and of performance, quite as much as a spatial and aesthetic construct.

The Camuda building, in its summary form is at once both simplistic and profound. Consistent rehearsal of principles and constant manipulation of form have enabled Yeang to reinvent the bioclimatic skyscraper in a number of notable types -the Gamuda-type. in itself, serves to inform a series of following developments, and in this sense, together with Menara Mesiniaga, is a benchmark project.
