• NYC alone generates 1.3 trillion.

• Tokyo’s is even larger at 1.4 trillion plus.

• Buildings that have sought Green certification is now at 850 m. sft.

• Set to touch 1 billion Sft before March 2012.

• That’s 1 green Sft for every citizen

• The first billion took nine years. The 2nd billion green sft will come in next 4 years.

• This year alone India is building 6 billion Sft. Gradually going up to 30 billion by 2030.

BCIL’s Zed variety

• no toxic paints for walls / metal / wood surfaces.

• nearly no plastering and paints for external surfaces.

• no diesel for gensets beyond up to about 30% of the fuel need. The

• rest 70 % is renewable energy or bio-fuels.

• We use only LEDs for external lights; not even CFLs are used for external lighting.

• only solar-based or other hybrids for external lighting,

• no reliance on either grid power or gensets for such campus lighting.

• No pure cement used, only composites.

• Costs us same as regular building

• Our customer price line is same, even less when competition is fierce

• Customers save 70% on energy bills

• They never suffer water shortage

• Their monthly campus maintenance cost is 35% less than regular apartments

• DON’T GO GREEN!

• Every 2000 houses can mean 1 million units of energy saved, or 10 MU’s generated with just the switch from Incandescents/ 40W T’lights … to CFL’s and LED’s.

• That’s 50 million units saved a year for a city like Chennai. Or 500 MU’s of power generation avoided.

• DON’T GO GREEN!

• Every 2000 houses can save 70 million liters a year. Nearly a week’s fresh water supply. With aerators / flow restrictors costing less than Rs

2000. That’s 4 billion liters a year for a city of 100,000 households.

• Treating gray/black water and looping for flush tanks can save a city like Chennai about

400 million liters of water a day.

• DON’T GO GREEN!

• Reducing Contract load to 3 KW per household can bring power demand estimates down by 40 pc.

• Treating wet waste locally in apartments and homes can save 25 million liters of diesel and about 400 cr saved, for a Bangalore city on just disposing Garbage.

• DON’T GO GREEN!

• Every 1 Lac Sft of a multi-stack building

means about 4200 cu. m of concrete,

400+ tonnes of steel, and 1/10th of a Sq km of river bed sand at half-a-meter depth.

• Every 100,000 Sft of a regular building means about 250 tonnes of copper for electrical cabling.

• DON’T GO GREEN!

• 1 tonne of steel means loss of about

300 tonnes of raw earth and about 100 tonnes of iron ore to be smelted. Not to forget energy used by furnaces.

• 1 MW of energy generated at any thermal plant means 500,000 kg of coal and 30% of this as fly ash.

Those Deeper Questions

• Can we disrupt?• A 100K Sft building weighs about 15,000

tonnes.

• A 2K Sft house weights about 280 tonnes.

• Can we bring it down to half the weight, with half the matter being renewable?

Those deeper questions

• What comes ahead on value chain?

• Can we move away from Architecture-led Services of the past?

• To Services-led architecture?

… deeper questions

• Before releasing a drawing …

• Can an Arch think of the river bed sand that that drawing will destroy?

• Of the limestone it will deplete?

• The forests it will destroy for coal the building will need?

What’s next at ZED Habitats?

• To make more housing projects with no WSSB, no ESCOM, no Sewerage board connections …

• Zero import of water, zero export of waste, zero import of energy.

• 1 million more Sft of such housing on anvil this year. In Bangalore, Chennai, Pune…

Next at ZED!
