GREEN BUILDINGS

INTRODECTION:-GREEN
Building Industry is producing second largest amount of Demolition Waste and GHG (almost 40%). BENEFITS OF GREEN BUILDING CONCEP:-
Buildings have major environmental impacts over their entire life cycle. •Green buildings are designed to be healthier and having more enjoyable working environment. Workplace
•Resources such as ground cover, forests, water, and energy are depleted to construct and operate buildings. qualities that improve the environment and which help in developing the knowledge of workers and may also
•Resource-intensive materials provide the building envelope and landscaping add beauty to it – in turn using up water and reduce stress and lead to longer lives for multidisciplinary teams.

•Energy-consuming systems for lighting, space conditioning and water heating provide comfort to its occupants •Significantly, better lighting quality including more day lighting, better daylight harvesting and use of shading,
• Hi-tech controls add intelligence to ‘inanimate' buildings so that they can respond to varying conditions, and intelligently greater occupancy control over light levels and less glare.
monitor and control resource use, security, and usage of fire systems etc. in the building. •Improved thermal comfort and better ventilation.
•Water is another vital resource which gets consumed continuously during building construction and operation. •Limited waste generation due to recycling process and reuse.
•Several building processes and occupant function generate large amount of waste. •Increase productivity of workers and machines. It is reported that productivity can be increased by about
FOR SOLVING THESE ROBLEMS THE CONCEPT OF GREEN ARCHITECTURE WAS FORMED. 25% while following such green house norms.

finding the balance between homebuilding and the sustainable environment.
KEY POINTS TO BE REMEMBERED:-
GREEN BUILDING DESIGN CONCEPT:- 1. Sustainable Site Design
TO HAVE A GREEN BUILDING DESIGN CONCEPY WE MUST FOLLOW THE FOLLOWING POINTS:- 2. Water Quality & Conservation
To have Green Building Concept, we should look after the following: Optimum use of Energy or power 3. Energy & Environment (MINIMIZING THE USE)
•Water conservation 4. Indoor Environmental Quality
•Solid and Water Waste management, its treatment and reuse 5. Materials and Resources
•Energy efficient transport systems
•Efficient Building System Planning etc. SOME INTERESTING GREEN BUILDING FEATURES IN THE PALLCIA ( LIVE CASE STUDY):-
If all Buildings in urban areas were made to adopt green Building concepts, India could save more than 8400 MW of power
which is enough to light half of Delhi or 5.5 lakh homes a year according to estimates by TERI A green building depletes very
little of the natural resources during its construction and operation. The aim of a green building design is to minimize the
demand on non-renewable resources and maximize the utilization efficiency of these resources when in use and utilization of
renewable resources.

CHARACTERISTICS OF A GREEN BUILDING:-

•Green Building i.e. energy efficient building is the one which can reduce energy consumption by at least 40% as compared to
conventional building.
•The cost of constructing energy efficient building is estimated to be 15 – 20% higher as compared to conventional building
without energy efficiency. This is more than compensated over the period of time i.e during life cycle cost and operation &
living. ALL UNITS HAVE CROSS LIGHTWELLS LIGHTWELLS VIEW FROM UNITS
•Using green building materials and products, promotes conservation of non renewable resources internationally. VENTILATION THROUGH ROOMS
