| Abstract | The paper presents the Levelized cost of energy - LCOE in the cost-optimal by linear optimization for energy services of Net Zero House Energy - NZEH, with Lisbon as the case study. The LCOE for the renewable technologies is applied in the optimization using solar collector biomass, geothermal, solar panel for the household energy services of space heating and water heating. The linear programing is able to give valid solution for simple options of separate technologies. Analyzing the costs that occur with such choices, it is showed that more renewable technologies to perform the same energy service, the more investment cost needed. Given the complexity in choosing the best technologies for energy services in NZEH - linear programming is not able to give such solutions that are best in efficiency, satisfy the required percentage of renewables and present a cost optimum. |
