Energy efficiency is built into all levels of operations at the COLOURS OF OBLU resorts. LED lights are installed in indoor and outdoor areas with timers for optimised energy usage. Villas feature inverter technology air conditioning, and the majority are fitted with efficient key-card based energy management systems. Most of the hot water demand (80%) is catered from renewable resources, such as waste heat from gensets (via heat exchange) or solar heaters. Battery-operated vehicles and bicycles are used for transport on the island, to reduce the environmental impact.
