4. INTRODUCTION
Green building(also known as green construction or sustainable building) expands and complements the building design concerns of economy, utility, durability and comfort.
A Green building is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provides healthier space for occupants as compared to conventional buildings.

5. What is a Green Building?
A sustainable or green building produces net zero or smaller carbon footprint or reduces the other harmful emissions.
It is a building which dose not have adverse effects on the ecological balance.
These structures don’t have a negative impact on the environment as they generate their own energy from solar energy, wind energy etc.

6. What are Green Features?
Minimal disturbance to landscapes and site condition.
Use of recycled and Environmental Friendly Building materials.
Use of Non-Toxic and recycled Materials.
Use of Energy Efficient and Eco-Friendly Equipment.
Use of Renewable Energy.
Efficient use of Water and Water Recycling.
Quality of Indoor Air Quality for Human Safety and Comfort.

7. Principles of GREEN Building
Siting and structure design efficiency

Waste reduction

8. Siting and structure design efficiency
Why it is important?
Foundation of any construction project is rooted in 2 stages:
i. Concept stage ii. Design stage
During all life-cycle stages of a construction project
Concept stage minimize impact on cost & performance
Design stage minimize impact on environment

9. Buildings are complex products of diverse materials & components of various design variables to be decided at the design stage
A variation of every design variable may affect the environment during life-cycle stages

10. How can we achieve it?
Materials & Elements : Should reflect, transmit & absorb solar radiation.
Energy Utilization : Use renewable powers to:
Reduce utility cost
Environmental impacts of energy
production
Location : Develop in pedestrian friendly to:
promote healthy life styles
alternate modes of transportation
Surfaces : If low traffic, use porous paved to:
assist onsite storm water infiltration
reduce erosion

11. Energy Efficiency Why it is important?
Aims to reduce energy consumption in :
embodied energy to extract, process, transport and install building materials
operating energy to provide services such as heating and power for equipment.
High-performance buildings use less operating energy.
Embodied energy has greater importance.
Make up as much as 30% of the overall life cycle energy consumption.

12. How we can achieve it?
Building Material :Wood instead of brick, concrete or steel
Orientation :Shade windows & roofs in summer
Maximize solar gain in winter Effective Window placement
Windows, Insulation :High Efficient for building envelope Barrier for conditioned space
Energy Utilizations :Renewable Powers like Solar, Hydro, Wind, Bio mass
Design :Passive solar building design Eg. Low-Energy Home

13. Water Efficiency Why it is important?
Aims in Reduction of water consumption
Protection of water quality
Demands on supply exceed the ability of aquifer to replenish itself
Unnecessary wastage of water resources

14. How can we achieve it?
Facilities : To increase the dependence of existing water
Recycling : Water treatment and Heating :
improves water quality & energy efficiency
reduces amount of water in circulation
Fixtures : Use water conserving fixtures
Eg. Ultra low flush toilets, Low flow shower heads
Design : Landscaping plan:
Native, water retaining, drought resistant plants
Rainwater harvesting system for irrigation
Dual plumbing system:
Reuse water for flushing, car washing etc.

15. Materials Efficiency Why it is important?
Efficient use and reuse of material reduces
i. Environmental impact ii. Liable cost
How can we achieve it?
Use non-toxic, reusable, renewable & recyclable materials such as
i. Coal combustion products ii. Foundry sand
iii. Demolition debris in construction

16. Should be extracted & manufactured locally to minimize embedded energy in transportation
Manufacturing in off-site & bringing to site will:
i. Minimize waste, noise &dust
ii. Maximize recycling
iii. High quality elements
iv. Better OHS management

Heighten aesthetic qualities.
Minimize strain on local infrastructure.
Improve overall quality of life.

21. GREEN Building Rating Systems
There have been building which adopt one or more green features. To recognize the extent of features that a building adopted, rating system have been evolved. The Green building rating system are the qualitative measures of sustainability and the actual benefits of green design.
Government body and policy guidelines responsible for assessing sustainability in building sector in INDIA:
NBC(National Building Code)
ECBC(Energy Conservation Building Code),2007
Local byelaws

22. The INDIA Green Building Council(IGBC), 2009 is actively promoting green building in INDIA.
The INDIA has currently two GREEN Rating System:
GRIHA-(Green Rating for Integrated Habital Assessment)
LEED-(Leadership in Energy and Environmental Design)

23. 1-GRIHA
GRIHA is an acronym for Green Rating for Integrated Habitat Assessment. GRIHA is a Sanskrit word meaning – ‘Abode’.
Human Habitats (buildings) interact with the environment in various ways.
Throughout their life cycles, from construction to operation and then demolition, they consume resources in the form of energy, water, materials, etc. and emit wastes either directly in the form of municipal wastes or indirectly as emissions from electricity generation.
GRIHA attempts to minimize a building’s resource consumption, waste generation, and overall ecological impact to within certain nationally acceptable limits / benchmarks.

24. GRIHA Rating System
GRIHA rating system consists of 34 criteria categorized under various sections such as Site Selection and Site Planning, Conservation and Efficient Utilization of Resources, Building Operation and Maintenance, and Innovation points.
Eight of these 34 criteria are mandatory, four are partly mandatory, while the rest are optional. Each criterion has a number of points assigned to it. It means that a project intending to meet the criterion would qualify for the points. Different levels of certification (one star to five stars) are awarded based on the number of points earned. The minimum points required for certification is 50.

25. GRIHA Rating System: Points achieved GRIHA Rating 50-60 61-70 71-80
81-90
91-100

26. There are a set of 34 criteria formulated by GRIHA to rate a Building:
Criterion 1 Site Selection
Criterion 2 Preserve and protect landscape during construction/compensatory depository forestation.
Criterion 3 Soil conservation (post construction)
Criterion 4 Design to include existing site features
Criterion 5 Reduce hard paving on site
Criterion 6 Enhance outdoor lighting system efficiency
Criterion 7 Plan utilities efficiently and optimize on-site circulation efficiency
Criterion 8 Provide minimum level of sanitation/safety facilities for construction workers

30. 2-LEED
LEED is an acronym for Leadership in Energy and Environmental Design.
LEED was developed by the US Green Building Council (USGBC), and it is the most widely used rating system in North America.
IGBC has taken steps to promote the GREEN Building concept in INDIA. Currently, IGBC is facilitating the LEED rating of the US in INDIA. LEED-INDIA was launched in 2001 and rates buildings by addressing performance in the following six areas:

31. Sustainable sites
Water efficiency
Energy and atmosphere
Materials and Resources
Indoor environmental quality
Innovation and design process
In addition, LEED- INDIA has adopted several benchmarks for building performance. The buildings are given ratings of ‘Platinum’, ‘Gold’, ‘Silver’ and ‘Certified’ based on GREEN Building attributes.
