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

• Green building consultant – TERI (The Energy & Resource Institute)

• Project got LEED Platinum rating in 2001

• TERI GRIHA released in 2005

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

CESE building IIT Kanpur – very little hard paved surfaces, lots of shading under trees

CESE building, two years after construction

CESE building IIT Kanpur – design and site planning respond to various site features like weaving the building around the trees, longest facades face north and south etc.

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.
