Civil engineers design, construct, operate, and manage public roads, buildings, airports, tunnels, dams, bridges, water supply and sewage treatment systems engineering construction, and maintenance, including the private sectors. The energy civil engineering building design is one of the most catalysts for wealth creation, economic growth, and social change in all countries. Buildings have a significant share of the total energy consumption worldwide; therefore, they profoundly impact the environment (Selects the construction area of these stages, architectural design , architecture and material selection, Construction, maintenance, disassembly, reuse, recycling, and waste disposal). The power building's life cycle has been used at all stages based on Field Programmable Gate Array (FPGA) and Embedded system. Embedded system is a civil design engineering that is often optimal for maximum compute output, no timelines, or business drivers. Energy consumption in buildings can be significantly reduced at every stage of the building lifecycle. The energy-saving method of construction lifecycle. Information about the building's life cycle, energy-saving, and explains the guiding principles in civil engineering buildings' life cycle design.
