Cost-benefits analysis of non-energy benefits (NEB) for each stakeholders and consideration for redistribution of NEB: Study on low-carbon communities and cities by use of decentralized energy network

1. This study has carried out a cost benefits analysis for each stakeholder in an attempt to develop low-carbon communities and cities by implementing regional cogeneration systems and leasing photovoltaic systems to commercial buildings. 2. As a result, the economic benefits for energy service provider acting as an investor have been proved when non-energy benefits (NEBs) are accounted. In addition, numerous benefits to stakeholders other than investor have been proved. Also, subsidies by public sector (National, Local Government) will increase the economic efficiency for energy service provider (investor). 3. Since building owners and building users will gain NEBs such as of increase in real estate value, risk reduction (contribution of business and living continuity plan (BLCP), regulatory compliance etc) and maintenance cost reduction, possibility for redistribution of NEBs to the energy service provider (investor) in the form of service charge (rent, energy expense etc) have also been considered.
