Other natural materials include bamboo poles set in beds of river stones. The poles create transparent dividing screens.
Elsewhere, curved partition walls are enlivened by bright graphics. Some of these feature text in several different languages a recognition of the multicultural background of the employees and the global nature of the company's business. Woven screens opposite key entry points ensure the working office areas are not a distraction for clients.
Tham says the office was designed so that 75% of the regularly occupied spaces have natural daylight. There are also daylight and motion light sensors to ensure energy is not wasted. And meeting rooms are glazed to maximise natural light, and to reinforce the sense of a transparent, open workplace.
"The open spaces are positioned close to the windows, so everyone benefits from the light and the views 90% of the seated spaces have direct outdoor views," says the designer. "There are also oxygen sensors that maintain optimum levels to ensure workers are not just productive, but also comfortable."
In keeping with the sustainable design brief, the office has achieved lighting energy savings of more than 30%, compared to similarly sized offices. The installation of water-saving fixtures has also led to a 20% reduction in water use.
Other environmentally friendly initiatives include the specification of materials with a high recycled content. Nearly a third of the furniture is from the former offices, and most materials have 20% recycled content. The timber flooring, for example, features recycled railway sleepers. Other materials, such as the bamboo, come from renewable resources. Low-VOC adhesives, sealants, paints, coatings, carpet systems, furniture and seating help to maintain a healthy environment.
