Discovery Kartika Plaza Hotel is a 5 star hotel located in the heart of the tourist centre in Bali. In 2007, Kartika hired Contained Energy to design and install an entire solar thermal hot-water system to supply their 318-rooms luxury hotel. The system consists of 144 flat plate solar thermal collectors that operate the hot water system from 7:30 am to 6:00 pm. 15-20 cubic meters of water is heated from 30-60°C each day.
Kartika’s decision to go solar has reduced diesel fuel consumption by 50%, from 400 L down to 200 L per day. The lower fuel consumption will reduce CO2 emissions by more than 600 tons per year and help Discovery Kartika Plaza in becoming ‘green’.
