Green buildings are energy efficient and environmentally responsible for sustainable human health development. Their design, construction and operational practices that consider sustainability will minimize their negative impact on the environment and people, while taking into consideration the financial impacts. Although solid energy policy architecture is in place, sustainable energy targets are weak, government support is limited, and bureaucratic hurdles for energy investment still frustrate potential investors. Most importantly, many top policymakers do not seem to be ready to play a productive role in designing a forward-looking, sustainable energy policy. Construction sector has a great potential to reduce total energy consumption through sustainable projects. All over the world policy makers have already realized the potential and begun setting some governmental goals. This paper discusses the green building concept for sustainable energy development.
