Green buildings incorporate unique construction features that ensure efficient use of resources such water and energy. For example, by using task lighting strategy and a lot of daylight, green buildings vastly reduce the amount of power used in lighting systems; This allows users to save as much as a third of 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. Even though constructing a green building may be slightly more expensive than their non-green counterparts, the reduced operation and maintenance costs of green buildings make them much cheaper in the long term.
Designers of green buildings try as much as possible to reduce dependency on energy from non-renewable sources such as coal. To this end, they install solar panels to make use of energy from the sun, and design windows in a way that allows as much natural light as possible and, therefore, reduces the use of artificial light; these and other methods ensure that the building uses energy in an efficient manner. Energy efficiency is essential not only for the user but also for the entire world because non-renewable energy sources are expensive and pollute the environment.
Indoor environment quality depends on conditions inside a building and how they affect the occupants of the building. These conditions include lighting, ergonomics, thermal conditions and air quality. Good indoor environment quality is one protects the health of the building's occupants, reduces stress and improves their quality of life. Green buildings achieve this through the installation of operable windows that allow in as much sunlight as possible and reducing the use of materials that may emit elements that are dangerous to the health.
Water efficiency involves using water resources in a manner that saves water and ensures 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 waste through the installation of plumbing fixtures that are efficient and reducing the strain on shared water resources by installing systems that purify water and enable recycling.
People who live in green buildings enjoy many health benefits because of the safety of materials used in the construction of such buildings. For instance, eco-friendly construction companies avoid using plastic by-products that have been found to release toxic materials. Toxic substances like carcinogens not only cause significant breathing difficulties but also increase the chances of getting cancer.
Material efficiency involves the use of physical process and materials in a manner that allows for the minimum use of materials without compromising the quality of the outcome; also, the processes should generate as little waste as possible. To achieve material efficiency, green building companies use materials that are long lasting, recycle and reuse some products, design buildings in a manner that allow for the use of fewer materials and employ processes that use less water, raw materials, and energy. All these help achieve material efficiency.
By reducing usage of energy sources that pollute the environment such as coal, green buildings contribute to keeping the environment clean. In addition, by reducing the levels of carbon (IV) oxide emitted to the atmosphere, they help to lessen the pace of climate change.
As population increases, local shared resources such as water and energy come under considerable pressure. Through the use of technologies and processes that increase water and energy efficiency, green buildings can reduce this strain.
As these benefits of green buildings show, it is possible for human beings to effectively meet all their present needs without depleting resources and endangering the environment in a manner that makes it difficult for future generations to survive comfortably. Eco-friendly buildings use unique construction techniques that ensure that resources are used efficiently and responsibly while not compromising on the user's health and comfort.
