The term “green” refers to The term “green” refers to environmentally friendly environmentally friendly practices from building practices from building design to the landscaping design to the landscaping choices. It also choices. It also encompasses energy use, encompasses energy use, water use, and storm water water use, and storm water and wastewater reuse.and wastewater reuse.

Introduction to Green Building
• Green building is the practice of increasing the efficiency with which buildings use resources - energy, water and materials while reducing building impacts on human health and the Environment, through better site, design, construction, Operation, maintenance, and removal complete.

Design criteria
1.Efficiently using energy, water, and other resources.
2.Protecting occupant health and improving employee productivity.
3.Reducing waste, pollution and environmental degradation

5. Indoor environmental
quality enhancement
• EPA ranks indoor air pollution among the top five environmental risks.
• Unhealthy air is found in up to 30 percent of new and renovated buildings.
• Of hundreds of EPA-regulated chemicals, only ozone and sulfur dioxide are more prevalent outdoor than indoor.
• We can improve the indoor air quality by:-
• Introducing plants to the indoor environment
• Plants can help maintain humidity, increase productivity, and scrub the air of dangerous chemicals.
• the ability of plants to clean the air could result in less demand for ventilation, leading to lower energy use by mechanical systems.

2. Green Roofs2. Green Roofs
• A green or vegetated roof provides the function of a conventional roof while allowing plants to grow on the surface.
• A vegetated roof includes water proofing, a drainage system, filter layer, a lightweight growing medium, and plants.
• An ‘extensive’ green roof has a relatively shallow soil profile (1 to 5 inches) and is planted with ground cover plants that are adapted to the harsh conditions of the rooftop microclimate.
• The vegetated cover protects the roof membrane resulting in a longer The vegetated cover protects the roof membrane resulting in a longer service life before replacement is required. service life before replacement is required.
