Duo Towers (“DUO”)

A solar study to demonstrate the regulatory compliance of an innovative façade

RWDI supported the design of DUO, a pair of landmark towers in Singapore’s Bugis district, by assessing the visual and thermal impacts of their distinctive honeycomb façades. While the brise-soleil shading was intended to reduce solar heat gains and enhance occupant comfort, Singapore’s strict anti-glare regulations required assurance that the design would not cause excessive reflections affecting neighbors, drivers, or pedestrians. Through screening and detailed receptor-point analyses, our team demonstrated that the façades effectively minimized glare and thermal effects, confirming compliance with local codes and validating the shading system’s dual role in both energy performance and environmental comfort.
