The current progresses, challenges, contribution to sustainable development
・The current progresses
It has been cut than planning
Energy cost reduction ・・・ 775juta/year Co2 reduction ・・・ 178ton/year
・The challenges
Water quality management of hot water supply is important
Regular maintenance of filtration equipment is required
・Technology replication opportunities in Indonesia
As a possible method.
In Working with companies in Indonesia to manufacture in Indonesia.
・Contribution to the sustainable development in Indonesia※ ex； In Bali Island, there are so many hotels◇The swimming pool and hot water for the shower◇The needs of air-conditioning12
