DUO is designed to meet Singapore’s Building & Construction Authority (BCA) Green Mark Scheme, an initiative to shape more environmentally friendly buildings and to promote sustainability in the built environment. The development achieved a GreenMark Platinum rating for DUO Tower and DUO Galleria, and a GreenMark Gold Plus rating for DUO Residences and its 5-star hotel in the recent BCA Awards 2013.

The development incorporates environmental strategies through passive and active energy-efficient design and naturally ventilated spaces. The building’s orientation is optimized to prevailing sun and wind angles, while the concave building massing captures and channels wind flows through and across the site, fostering cool microclimates within the shaded outdoor spaces. Leisure zones and gardens act as a connector between multiple transport hubs and establish a flow of tropical green and lively communal activity, accessible to the public 24 hours a day.
