Green building aims to reduce environmental impact and improve occupant health. It incorporates architectural features, water and energy efficiency, materials selection, waste management, indoor air quality and thermal comfort. Converting an existing building to green involves adopting green practices during design, construction, renovation and reconstruction. This presentation compares an existing building to the same building converted to green, highlighting improvements like rainwater harvesting, LED lighting, low-VOC paints, and rooftop gardens. Certifying the converted building as green would provide tangible benefits like energy and water savings as well as intangible benefits like better indoor air quality.

3. WHAT IS GREEN BUILDING ?
• “A Green Building is one which uses less water, optimizes energy efficiency, conserves natural resources,
generates less waste and provides healthier spaces for occupants, as compared to a conventional
building.”
‘Green’ Symbolizes Environmental Sustainability
• Green building addresses the following: -
• Architectural features
• Water and Energy efficiency
• Materials
• Waste Management
• Environmental Aspects
• Indoor Air Quality
• Occupants Thermal Comfort

4. CONVERSION OF A CONVENTIONAL BUILDING TO A GREEN BUILDING
• NATURAL ENVIRONMENT, HUMAN HEALTH, AND THE ECONOMY HAS BEEN
AFFECTED A LOT BY BUILT ENVIRONMENT.
• WE CAN IMPROVE BOTH ECONOMIC AND ENVIRONMENTAL PERFORMANCE BY
ADOPTING GREEN PRACTICES
• GREEN CONSTRUCTION AT ANY STAGE CAN BE IMPLEMENTED IN BUILDING, FROM
DESIGN AND CONSTRUCTION, TO RENOVATION AND RECONSTRUCTION.
• ADOPTING GREEN PRACTICES FOR AN EXISTING STRUCTURE AND CONVERTING IT
INTO GREEN ONE IS LATEST INNOVATIVE TREND.
