CASE STUDY

GREEN BUILDING…???

A green building is the one that:- Is environmentally responsible. Is healthy place to live and work. Results in low cost ultimately.

GREEN BUILDING FEATURES

Eco-friendly- by least disturbance to eco-system.

Energy efficient- through natural lighting, ventilation and solar passive designs.

Efficient use of water- through recycling and water harvesting.

Use of renewable energy- through photovoltaic systems and solar heating systems etc.

GREEN BUILDING FEATURES

Indoor environment. Use of recycle/recyclable materials i.e.

minimum wastage. Efficient waste utilization and disposal. Use of non toxic materials.

WHY IT IS NECESSARY TO

MAKE THE BUILDING

GREEN???
