Abstract—Many countries around the world have been executing district heating system projects to promote the efficient use of energy and boost the reduction of greenhouse gas emissions. Unlike Japan and European countries where the district heating system projects have been successfully implemented, Korea has difficulties in executing the projects because of supply heavily relying on new housing sites; fuel costs of energy and supplying market prices; and conflicts over interests between government-owned agencies and suppliers, thereby producing low profitability and accordingly low feasibility and distribution rate. Still, the stakeholders are only focusing on policy discussion to find out ways to solve the current problems, and the local governments that have adopted the system have yet to settle the system taking into account heat density and heat distribution ratios among heat source, heat transport, and heat using facilities, as was established for housing site planning. This research selected an area where the district heating system was adopted as a research subject, analyzed energy heat load characteristics for building usages by dividing the subject area into residential and non-residential areas, and identified energy load ratios by building usages against the supply scale of the heat source facility 
Index Terms—district heating energy system, IEB (Integrated Energy Business), Heat supply load ratio, CHP (Combined Heat & Power), PLB (Peak Load Boiler)
