Study and Simulation of Low Energy Solar Powered House in Libya
Abstract
This paper was prepared within the program of a national action plan for energy efficiency, where a building code will be prepared within this program in Libya. The goal of this work is to build a simulated environment that can accurately assess the energy consumption of a six-person, one-story family house. The simulation will consider the hot water heating system, the cooling and heating systems and the selection of building materials that help conserve energy. The TRNSYS model is built and programmed to evaluate system performance on an hourly basis throughout the year. As a result of using an insulating material for the building envelope, the cooling load of the building loads were reduced by 60% compared to the original design of the project. In addition, a hot water solar heater is used to produce around 3700 kWh (with solar fraction of 82%) of hot water yearly. A 6-kW roof top PV system is designed for this house. The total electric energy produced from this system is 10500 kWh.
