Methods to reduce carbon footprintGreen building

A building is considered “green” when it saves resources and money. In addition it protects human health and the environment, and creates a healthy living space. A green building is one which is more efficient, economical, healthy and environmentally friendly. To become green, a building needs to use materials and resources that are of recyclable content, it maximizes the use of renewable energy, it conserves water and creates a healthy indoor air quality.

Examples- Study of the pilot office building – Focused on building materials
