The overall majority of public works construction projects in Japan nowadays include an overall greatest value assessment or are conducted using a (technical) proposal method/Comprehensive Evaluation Bidding Method. For ESCO Projects it is more specifically for projects where suppliers provide comprehensive energy-saving designs for public buildings.
