Ecological Design In The Tropics (EDITT) is a proposal by TR Hamzah & Yeang for a 26-story high-rise constructed of recycled and recyclable materials featuring photovoltaic panels, natural ventilation, and a biogas generation plant all wrapped within an insulating living wall that covers half of its surface area. The eco-tower is designed to collect rainwater and re-distribute its grey-water for both irrigation and toilet flushing with an estimated 55% self-sufficiency and a photovoltaic system that can supply 40% of its energy needs.
