This is because Green buildings blend the unique construction features that ensure efficient use of resources such as water and energy. For example, by using task lighting strategy and a lot of daylight, green buildings immensely reduce the amount of power used in lighting systems, this allows users to save their water and energy bills. Given that operating and maintenance costs can account for as much as 80% of the lifetime costs of a building, reducing such costs significantly increases the earnings of building owners who collect rent from their buildings. Although the cost of constructing a green building may be slightly more expensive than non-green buildings, the reduction of operating and maintenance costs of green buildings makes them cheaper in the long …show more content…
And there are three type of efficiency: energy efficiency, water efficiency and material efficiency. And for the energy efficiency, this is due to the reason that designers of green buildings try to reduce reliance on energy from non-renewable sources such as coal. And these buildings save energy more than brick buildings. They only depend on all renewable energy resources such solar power, hydro-power and wind power which are used for heat and electricity and they design windows in a way that allows the natural light get in, therefore, Energy efficiency is essential not only for the user but also for the world because non-renewable energy sources are expensive and pollute the environment. On top of that, the second efficiency will be water efficiency The way to increase the efficiency of water use is to save water and ensure that today and future generations enjoy a reliable supply of clean water. Green building allows for the use of alternative sources of water such as rainwater, reducing water wastage by installing the effective plumbing fixtures that are efficient and reducing the strain on shared water resources by installing systems that purify water and enable recycling. Apart from that, the last is the materials efficiency, this is due to the reason that green buildings are built from natural, non-toxic eco-friendly and recycled materials such as bamboo, straw, recycled metal, concrete and
