GRIHA Council Presents
Green buildings & sustainable habitat : The GRIHA way
The Energy and Resource Institute
Why green building?
Why rating?
Why GRIHA?
The 3 big questions???????????
1 2 3
Role of construction and buildings in development
Energy shortage of 2.1
per cent, or 24,077
million units (Mus)
48.8% population urban
by 2030
42% annual electricity
consumption attributed
to by buildings
Water and Waste: prevailing urban challenge
Water availability to
decrease by 15% per
capita 2020
Only 26% of estimated
domestic waste water
gets treated
42 million MT of solid
waste generated in urban
area daily
Challenges
• India has: – 2nd largest population
– 12th largest economy
– 70% population in rural areas
– Rapidly expanding urban areas
• Rising: – Energy consumption
– Associate GHG emissions
– Water consumption
– Unhandled waste
– Urban flooding
– Urban heat island effect
Policy response
• National Building Code • Energy Conservation Building Code • Appliance star labeling programme of BEE • Environmental Clearance/ EIA norms • Central Pollution Control Board guidelines • National Mission on Sustainable Habitats • Jawaharlal Nehru National Solar Mission • Solar buildings programme for energy efficiency • Solar cities programme • Waste to energy programme
Lack of integration and uniformity and clarity on application domain (e.g ECBC does not talk about residential buildings); Environmental clearance is a nightmare for many builders; no integration between comfort standards of NBC and efficiency standards of ECBC, implementation challenges- govt works in silos
GRIHA compliant building: beyond ECBC
ECBC Compliance: •Insulation
•High Performance glass
•Controls
•Efficient electrical , mechanical and
lighting systems
Incremental cost: 15%
Payback period < 5 years
GRIHA Compliance: •ECBC +
•Passive principles (shading,
orientation, controlled glass area)
•Higher indoor design conditions
(higher by 1 deg C)
•Optimized lighting design
No further incremental cost
Payback period: < 4 years

Puts emphasis on Human Comfort – since that’s what
buildings are designed for!
Enhancing transparency and ease
• Web enabled GRIHA online tool for project documentation and evaluation
• GRIHA app: to enhance accessibility and one to
one connectivity between GRIHA and the project proponents
• Pre certification meetings through skype: to avoid
the extra financial burden of travelling and enhancing accessibility to the GRIHA Secretariat
Building capacity
• Project design charrettes
• GRIHA training programmes for Evaluators and Trainers
• Setting up Centers of Excellence
• Developing curriculum
Other benefits of aligning
with GRIHA

Energy Saving Water Saving Waste management
Economical Health Time management
Electricity and water security for customers: first choice for purchasing property!
Faster construction
Systematic operations on site
Minimal health related issues on site
“ Malaria outbreak avoided at a project site in Tirupati due to regular fumigation of labour hutment”
Faster hence cheaper

Continuous handholding support…
• Continuous engagement: – Workshops for technical
staff
– Engagement on site for contractors/engineers
• Regional Secretariat presence in Pune, Mumbai, Bangaluru, Goa, Bhuvneshwar, Assam

…continuous handholding support
Examples of good practice
1. Tree protection
2. Mulching of top soil
3. Demarcation of construction area 4. Barricading along site

General Information
More than 80% of the regularly occupied spaces receive optimum daylight. The building is optimally oriented and façade is designed such that the heat gain is minimized and daylight is maximized.
• The landscape water demand has been reduced by minimizing the turf area, planting only indigenous species and using drip irrigation system for shrubs and trees.
• Building water use has been reduced by using low flow fixtures. • Phytorid technology based STP of 25 kLD capacity has been installed on site. 35 kL of storage tank
has been installed to collect rainwater for use in the building.
• Landscape has been designed to maximize green area and minimize hard paving. The net paved area is only 21.32% of landscape area.
• Fly ash has been extensively used in the project in RCC, mortar plaster and in the form of AAC blocks.
• Low energy materials such as unpolished stone and ceramic tiles have been used.

General Information
• Optimum window openings • Light floor for light diffusion • Soft landscape outside giving no reflected glare • Shaded walls and openings
• Buildings placed such that minimal trees are cut and agriculture is not impacted
• Buildings on hard ground to save on foundation cost . • Layout based on hydrogeological survey’s inputs so
that development does not impact negatively the recharge and discharge zones of water.
• Use of precast arch panels for roofs • Use of Stabilized Soil Cement blocks on walls and maintaining the same unplastered. • Double tile roofing for final roofs.
• CSEB based construction that has an embodied energy of 1% the regular construction(0.275MJ/Kg energy in CSEB wall and 72.3MJ)
• U-Block and arch lintels, CSEB arch panel roofs • Use of quarry dust to replace sand
• Solar Electric panels of 30KW capacity • Solar water heaters of 500L capacity • Biogas plant processing the food wastes & animal waste and producing 30cu.m gas • Recovering up to 95% of sewage water using a green sewage management
technology called Soil Biotechnology, which is used for landscaping.
Soil Bio-Technology at Govardhan Eco Village
• The civil cost was estimated around 750/sqft including brickwork. Additional expenses were floor finish, electrical, plumbing, bio-gas plant, furniture, kitchen equipment, solar water heater and solar power plant landscaping etc. Paint work was negligible as it is only done in some beams and some columns.
• Use of old bricks in construction.
