    Sustainanble Architecture……an introduction
                      Los Angeles, California

* Man has always depended on nature for it’s needs; taken so much yet
redeemed so very less. To be true man has always robbed nature.

* co-existence between nature, man and man-made structures a must.

                      *The mutations in interpersonal relationships and
                      intergenerational gaps, technological development,
                      mass migrations and globalization have transformed
                      the spaces in the urban landscape.

                     a city with high inputs (of energy,food etc)and high
                     output (thermal output,sewage etc) is less likely to
                     ‘hold’ and thus keep up and is less sustainable (derived
                     from sub-[under] and tener-[hold] means to hold under)
                     than a city with less input and output.
               Need for sustainability :

* meeting the needs of the present without compromising the ability of future
generations to meet their own needs.

* Technological advancements, sophistication, infrastructural conquests, never
thought before designs, well…. a never ending list fuelled to excel . This is what
we see today.

*Due to all this we have a sorry loser in the form of nature. It has been
receiving unkindly blows every time – ever decreasing resources, increasing
pollution,congestion and all.

* these days an architect can’t turn over a mossy green
rock without finding the word sustainability written under it!!
Strange it may seem!! But this seems to be the only option
whereby humans and other forms of life will flourish on the
planet forever.


* inadequacies and the negative impacts of past choices and
related mechanisms.
                   Measures for Sustainability


  * Sustainably designed buildings aim to lessen the impact on our
environment and the building’s occupants through energy and resource
                              efficiency.

 * merging of innovation with technology,
         sustainability, function.

 * Architecture a hope for sustainability.



                   •1) Modular Building Blocks2) Reconfigurable Spaces
                     •3) Decentralised urban plannin4) Passive Energy

    * considerations like feasibility, affordability,materials etc
                          Kenectic energy
* Reduce pollutants, recycle, reuse when possible



 * Provide sustainable, easily available building materials
where possible blending it with the vernacular architecture
                  of that particular place.


* Reduce the stress on nature and opt for alternate means.
                        modular housing

* Earth provides us with a finite amount of natural resources

* Should be used in proper way

* When selecting products and materials to use in your home,
look for ones that have:

 High levels of:
  > Renewability, Reusability & Durability

 Low levels of:
   > Embodied energy, the energy required to extract, process,
and transport materials
   > Environmental impact, the negative effects on outdoor
and indoor environments

* It allows a flexible adaptability

* A specific module is selected

* Containing all the necessary electrical
 equipment

* Attached to each other with a seamless flexible connection

* Attached to the corridol ,shared walls (provides the
capability of expansion to a shared common place )


                                      * A systemic modularity allows infinite
                                      shapes and combinations.
                       Decentralized urban Planning
The primary motivation of the design lies in creating a design
solution that is flexible and adaptive at any scale, and at instances,
responsive and intelligently active with respect to the changing
individual and climatic contexts.

Accordingly, the goal for the sustainable urban place was to provide
a framework for flexibility that can be configured and reconfigured on
two scales.

Firstly, to satisfy the immediate desires of the community and users
with the capability of adaptability and expansion to meet the changing
needs of the urban place programmatic spatial requirements, and
secondly on a local scale to optimize the building for changing
environmental conditions.

Such adaptability then aims to meet the changing needs of the
users and their activities/environment for comfort and optimum spatial
efficiency and thermal conditions.
        Decentralized urban Planning

new kinds of built from based on factory-produced materials, with
individual lighweight transportable homes located in natural
countryside, thus creating a “townless, fully decentralised, and even
populated country” .

metropolitan region are not a harmonious equilibrium of city and
surroundings, but as fundamentally shaped by the actual behaviour of
individuals.

whether to concentrate development at higher densities within the
existing urban envelope, or whether to encourage decentralisation to
new areas or satellite communities.

residents look to their immediate surroundings rather than to the
city for their jobs and other needs.The dispersed settlement structure
is truly multicentered.
     Decentralized urban Planning
Decentralization destroys both “nature” in its natural form and “society” in
its civil form.

metropolitan region are not a harmonious equilibrium of city and
surroundings, but as fundamentally shaped by the actual behaviour of
individuals.

“The urban field as an artificial environment”.


The nature of the city is that it turns nature to the city.


Spatial balance as a key concept amounted to a decentralized urban
system based on three basic principles: these were identified as urban
spread, the development of corridors and the appropriate use of energy
and transport.
           Decentralized urban Planning
spread cities seem to have more advantages than the disadvantages
   because of the following reasons:
1. Compact cities would consume the open spaces making our cities’
   environmental quality poor;

2. The compact city policy would result in the neglect of our rural
    communities.although it makes up a fraction of the population, it
    controls the policies for the entire archipelago.

3. The compact city would cause congestion, increase pollution, loss of
    space and reduction of privacy;

4. Social gaps would grow as a result of high cost of accommodation in
    the city centers and;

5. Compact cities mean massive financial resources.Compact cities
    maybe more efficient in terms of transportation and energy
    consumption. But if we are to scrutinize the negative effects of the
    “compact”loss of rural to urban migration and consequently the slow
    development of the rural communities, we can see that it outweigh
    its benefits.
                               Energy
                      Passive Kenectic      energy
 Due to the incident solar radiation in the courtyard, the air in it
becomes warmer and rises up to replace it cool air from the ground
level flows through the covered opening of the room. Thus,
producing the air flow.
The roof surface are sloped towards the interior courtyards. Time
cools air. It sinks into the courtyard are enter the lower spaces
through vents and low level openings and leaves through high level
opening.
Courtyards with cut parapets permit coo lair to flow into the
building at night.

                       Passive Kenectic       energy
Traditional clear storey windows with projecting shade provide
diffuse light to create uniform ambient lighting in interiors. It helps
in producing an effective stack effect for better ventilation,
prevents glares and thereby lieat gains.

One of the common passive shading device feature is a
balcony whose upper portion is effectively used as a winter living
space and at the same time provides edequately shaped buffer
spaces below to create comfort condition during summer.

As the temperature of soil ant bout six inches or more below the
surface of the earth, if a pipe is buried underground at this depth
atmosphere’s air is passed or circulated through it. The air will
lose or gain heat depending upon whether it is.

When a hole is made at the apex of a dome or cylindrical roof.
The low pressure at this point vents the hot air under the roof. In
this way air is kept circulating through the room under the roof, air
vents are usually placed over living rooms, often with a pool of
water directly under the vent to cool the air which is moving up to
the vent by evaporation.

In addition to shading, this arrangement provide an increased
surface area for radiative emission, and an insulating cover of still
air over the roof, which impedes heat flow into the building white
still permitting upward heat flow at night.

Terrace garden should be provided to reduce heat gain through
exposed roof.

Curved roof has a larger convection heat transfer area and
transfer heat more efficiently than a flat roof therefore, a curved
roof is more easily cooled.
