Development of a Renewable Energy Facility Design and Its Simulation Case Study

Economic feasibility was conducted regarding the regulation that dictates obligatory installation of renewable energy facilities in small proportion. A concern is how to allocate the capacities of candidate facilities (solar collectors, PV cells and geothermal heat pumps) with minimum cost, and meet the obligatory energy supply proportion. A design rule has been developed, with which a designer can tune his or her design strategy between installation cost and LCC. This was derived mainly from documents regarding the KEMCO installation guide. It was concluded that PV was the cheapest, with respect to installation cost, but a geothermal heat pump was the most recommended, when LCC was also taken into account. The proposed design result was also confirmed, by simulation results obtained from Energy Plus.
