Development of a software package for community energy system assessment – Part I: Building a load estimator

As part of an assessment software package for community energy systems, a database application is developed to systematically calculate the energy demands for mixes of 12 different types of building in Korea. The program generates the hourly demands for electricity, heating, cooling, and hot water for the mix of building types for 8760 h of a year. The calculation is based on field and measured data from major cities throughout the country. The energy demand curves generated by the package can be applied to the basic design processes of CESs (Community Energy Systems).
