Transcript of 160215_SitePlanning_V1501

Of this century...
...consider
...as we know it
The built-up area in Indian cities will grow several-folds in the coming decades. The urban population will continue to rise from 28% currently, to about 60% by 2050.
The BIGGEST challenge
The World...
Take a moment and..
That for the past 65 years we have done NOTHING but look to developed countries for solutions to OUR problems
That that is mostly because the problem was created by following foreign models to begin with

Version 2015
From our Constitution...
The 42nd Amendment
National Ambient Air Quality Standard
NAAQS kat gayi!!
In 1976, under the leadership of the then Prime Minister, Smt. Indira Gandhi, the Constitution (Forty Second Amendment) Act was passed and the provisions relating to the protection of environment for the first time were incorporated by adding a new provision Article 48-A in the Chapter, Directive Principles of State Policy.

According to Article 48-A “the State shall Endeavour to protect and improve the environment and to safeguard the forests and wildlife of the country”.

Further, a new provision Article 51-A in the form of “Fundamental Duties” was also incorporated by the 42nd Amendment. According to the sub-clause (g) of Art. 51-A, “it shall be the duty of every citizen of India to protect and improve the natural environment including forests, lakes, rivers and wildlife and to have compassion for living creatures”.

The above two provision impose two-fold responsibilities. On the one hand, it gives directive to the State for protection and improvement of environment, and on the other hand it casts/imposes a duty on every citizen to help in the preservation of natural environment.
GRIHA TIMES
“mA ghridam kasyasviddhanam”
(Ishavasya Upanishad – 300 to 15- B.C.E.)

“Thou shalt not covet thy neighbor’s wealth”
(Bible – 12 to 2 B.C.E.)

And do not wish for that by which Allah has made some of you exceed others. For men is a share of what they have earned, and for women is a share of what they have earned. And ask Allah of his bounty.
(The Holy Quran 610 - 632 C.E.)
in all of this
INDIA
A REVEALING COMPARISON!
who do we want to be when we grow up?
That ALL that has yielded NOTHING but
Crowded cities
Frustrated people
Traffic jams
Social Inequity
Spiritual unrest
Aggressive Competition and disharmony
Pathetic replicas of foreign phenomena including architecture
Mass destruction of our natural resources and forest cover
Is there an end in near sight?? Or ever?
will
"India plans to get a new atmosphere by the year 2025 to accomodate the lethal air pollution levels in all metropolitan cities.

That will boost the sales of cars and impact the economy positively."

"Protecting tree cover and increasing the forest cover is against our religion and out of the question." politicians said.
The "IDeA" - Integrated Design Approach
NBC, 2005 - PART 0 (ZERO)
This section is titled ‘PREREQUISITE FOR APPLYING PROVISIONS OF THE CODE’.

It calls for an approach to design and construction that includes all the consultants from the beginning itself.

In other words, all the project proponents, sit across the table, and agree on a common outcome for the project.

This drastically reduces later confusion (time and material overruns and increased project costs)
People required for "IDeA"
Architect
Civil engineer
Structural engineer
Electrical engineer
Plumbing engineer
Fire protection engineer
HVAC engineer
Environment specialist
Town planner
Urban designer
Landscape architect
Security system specialist
Interior designer
Quantity surveyor
Project/construction manager
Other subject specialist(s)
But what about pollution, energy consumption, carbon emissions, and so on?
Make in India!
Notwithstanding their high overall rating, there is hardly any difference in the scores obtained by mncs and Indian companies in environmental performance at the production plant and supply chain management. A fact corroborated by grp's green inspectors, who undertook nationwide site surveys. Domestic players have actually fared slightly better in the production phase. It has been observed that instead of showing the way by using new production technology and encouraging suppliers of components to be eco-friendly, mncs have conveniently adopted cheaper local practices. Consequently, there is a wide disparity between their plants in the West and those in India. Another example of their discriminatory approach.
Most pristine rivers will have a 5-day carbonaceous BOD below 1 mg/L. Moderately polluted rivers may have a BOD value in the range of 2 to 8 mg/L.

Municipal sewage that is efficiently treated by a three-stage process would have a value of about 20 mg/L or less.
Heard of the "Once Through" System of power generation?
Save Energy to Save Water!!
We consumer 80,000 liters of water per megawatt hour of energy generation (US = 100 - 120 K liters)
Delhi’s demand is over 100 million units per day
That in itself needs
80,000 X 100,000 (MWh) = 8,000,000,000 liters of water to generate
Delhi supplies
3,200,000,000 liters of water per day
So our total water footprint is
11,200 million liters of water per day
In other words, enough water to serve 82.96 million people per day
The problem is – Delhi’s population is 25 million
