Green Buildings :The Journey So Far and Way Ahead

31 October 2012

Green Building Congress


IGBC Vision

� Enable ‘sustainable built

environment for all’

� India to be one of the

global leaders in

sustainable built

environment by 2025

Buildings Habitats


Building Sector - Expected Growth

Year* 2012 2020 2030

Built-up Area*

(Billion Sq.ft.)

25 50 100

� Construction in the next 20 years >> past 100 years

� 207,000 MW installed capacity

� Need to add one 500 MW every 10 days for the next 10 years !


What We Want To See

� French doctor who

perfected cataract

operation (1970s)

� Cured millions of

people

� Some of them

blinded themselves

again

� To be in a world that

they earlier imagined


Major Aspects to be Addressed

1. Fossil fuels : How much and how far ?

2. Soil : A Natural capital

3. Waste : Lessons from Nature

4. Virgin Materials : The Mindset changes

5. Water : The paradox of plenty

6. People’s Health : Quality of life


1) Fossil fuels : How much and how far?

� 1970s

� How much of oil is left ?

� 2000s

� Whatever is left, can we

burn them ?

� About 30 Billion tons of

CO2 released into

atmosphere every year*

*Source :’The Ecology of Commerce’ by Paul Hawken


Transportation : The Impacts� 85% of crude oil is imported

� What is the average speed of

our cars on the road ?

� 60 kmph/40 kmph/10 kmph

� 30 km/day – 3 hours

� 10 kmph

� Speed of a bicycle !!!

� 1 litre of petrol : 2.31 kg CO2*

� 6 kg of CO2 every day !

� A fully grown-up tree can

absorb 20 kg CO2 per year !!!

To travel at the speed of a cycle we are devastating

our earth, air & health

2) Soil : Most Neglected Natural Capital

� Globally 25 Billion tons of top soil is lost every year *� Takes 500 or more years to enhance its fertility

� Definition of top soil has undergone a shift� 21” to 6”

� Using fossil fuels to transport top soil !



3) Waste: Lessons from Nature

� Nature’s waste is not waste at

all

� Every week on an average

human beings consume

10-15 kg of resources*

� 800-900 kg of waste is

discarded to support this

consumption

� Fossil fuels again used to

transport waste !



Waste Management

� Segregation is the key

� Bangalore example

� Municipality would

henceforth not collect

dry waste mixed with

wet waste

� 4000 T / day

� Every green building

� 450 T / Million sft

diverted


4) Virgin Materials : The Mindset changes

� Wood : An Architect’s

Delight

� Between 1975 and 2005

� World’s forest reduced by

608 million acres*

� 1991: 42 million acres

cut or destroyed*

� Highest destruction ever

in the history of mankind



Use of Salvaged Materials� Excellent example of changing mindsets

Energy spent in transporting timber & adding value is significant


Saltwater97.5%

Freshwater2.5%

Total potable water available < 1 % of world’s wate r

Groundwater30.1%

5) Water : The Paradox of Plenty


Moving towards Physical & Economic Scarcity

Source: International Water Management Institute analysis done for Comprehensive Assessment of Water Management in Agriculture using Watersim model.

� Physical water scarcity: Available water resources < demands

� Economic water scarcity: Investments required for growing water demand

are constrained by financial, human, or institutional capacity

� Water embedded / hidden in product


Water Performance

� Green Homes / commercial

buildings

� Rs. 800 - 1200 / tanker

� 30 – 40 % of this is towards

fossil fuel spent in transporting

6) People’s Health – Quality of Life

� People inside the

building

� Most important

asset

� Mindset changes

required

� Indoor air needs to

be in designer’s

priority


� If we are conscious about milk, why not paints ?

� Can we walk into a vendor shop & select better

paints ?

Low VOC Materials


Market Transformation


The Cost Paradigm

� All this is Fine ;

But what about the Cost ?

� Decreased from 12% incremental cost to 3% in 10 years

� Life-cycle cost

� Who would ultimately pay for the cost of natural capital ?

� Even if one pays, will it be available ?


Would the Consumer Pay ?

� 47% of leisure travelers

indicate that they

would pay between

$ 1 - $ 5 per night to

participate in a carbon

off-set program

For the Doubting Thomases

� How will these buildings

perform ?

� Any building with good design will

only perform well

� Data of energy consumption

reported by certified projects

are in IGBC website

� www.igbc.in

Benefits Achieved : Commercial Buildings

Data collected from 40 IGBC Rated Green Buildings so far


Benefits Achieved : Homes

� Lower monthly energy bills

than the neighbour (20 -30%)

� Every urban home can light up 35

village homes /year !

� Rain water Harvesting – can

provide free water for 3-4 months

� Every urban home can provide water

to 1 village home for the entire year !

� Green occupants would live longer !

� 80% of heart attacks due to stress

� Green Homes can provide serenity


� Let us not start installing renewable

after all our fossil fuels are gone

� Let us not start planting trees after

destroying the plant & animal species

� Let us follow our grandmother’s wisdom

� Do not dig the well when you are thirsty

To Sum Up…
