Sustainable Building Matters: Benefits for the Environment and Your Wallet

I. Introduction - A civil engineer is a professional who designs, builds, and maintains infrastructure such as roads, bridges, buildings, and water and sewage systems. They use their knowledge of mathematics, physics, and materials science to ensure the safety and functionality of these structures. Civil engineers also take into account factors such as environmental sustainability and cost-effectiveness in their designs. They work closely with other professionals, such as architects, construction managers, and surveyors, to bring their projects to fruition.

A. Definition of Sustainable Building- Sustainable building, also known as green building, is the practice of designing, constructing, operating, maintaining, and deconstructing buildings in an environmentally responsible and resource-efficient manner. It involves minimizing the negative impacts of buildings on the environment and human health, while maximizing their positive impacts, such as energy efficiency, water conservation, use of renewable resources, and indoor environmental quality. Sustainable building considers the entire life cycle of a building, from its design and construction to its operation and maintenance, as well as its eventual demolition or adaptive reuse. The goal is to create buildings that are socially, environmentally, and economically sustainable.
