A lot of efforts have recently been made to design and construct energy efficient, ecologically sustainable offices generally regarded as "Green Offices". However, the sustainability focus can often be dimmed once the building has been occupied. A highly sustainable "green" office can still perform poorly if performed inefficiently. The final performance of green offices highly depends on their users'awareness. On the other hand, some general practices can improve the efficiency of conventional offices in terms of green features. The aim of this study is to evaluate the level of awareness towards green office occupancy requirements.
