“ RESPONSIVE REUSE is the parallel process
of reinvigorating an existing building by physically
transforming its mass, adding a new structure on
top, and connecting them with new architectural
and programmatic elements. The existing building is made more efficient by subtracting volume
from the centre, and converting the dark inner
core to parking. The overbuild is a perforated, donut shape that enhances natural ventilation and is
fitted with an adjustable, responsive facade calibrated to changing climatic conditions.

Total energy consumption of building is one
of the main focuses of environmental designer. Energy simulations help in understanding holistically
energy consumption of building in different aspect
such as heating, cooling, lighting and plug-in loads.
It provides data in various formats which further
helps in deciding design strategies according to the
climatic conditions and locations. One can provide
#2 various inputs in terms materials, systems, technologies, schedules etc and predict the energy usage of the building.

- Helps well in decreasing the peripheral glare and discomfort
- Effect of inside illuminance and reducing peripheral glare and discomfort depends on width of light shelf, location (inside, outside
or both), vertical positioning, its angle and also on dimensions and
type of glazing.
- Depending on the requirement of the space, one can decide upon
having light shelf either interior, exterior or both, as they all have different effect on illumination at interior space near perimeter.

LIGHT SHELVES- EXPLORATION AND EVALUATION

- For location near equator,
light shelf doesn’t work during months around March
and September as sun is almost overhead.
- Light shelf works equally
well for north and south façade.
- Illuminance level is almost
similar inside space in the
central part during early
morning (9am) and late afternoon (3pm) as sun penetrates the space at almost
similar angle from south.
MOSCOW, RUSSIA
- For location moving far
above tropic of cancer, light
shelf doesn’t work during
months around December as sun is at very low
altitude, even during noon
time.

- Light shelf works well for
months between months
from March to September
as sun is at higher altitude
compared to other months.

DAY LIG HTIN G

The objective of this research is to understand and highlight the effectiveness of light
shelves in different geographical region and their
effect in illuminance level inside the space. Daylight simulations were performed for a custom
light shelves (plastic material) for a typical space
in two different location - 1) Moscow, Russia and
2) Male Hulelu, Maldives. Moscow, in Russia, is located at 55.7 degree latitude and Male Hulelu, in
Maldives, is located at 4.2 degree latitude. Simulations were performed using Ecotect and Radiance
and weather data for both the space were taken
from U.S Department of Energy website. Simulation readings were taken both for sunny as well as
overcast sky, during 21st of March, June and September. For Maldives, readings are taken at 9 AM,
12 PM and 3 PM of day and for Moscow, readings
were taken at 9 AM, 12 PM and 5 PM. Along with
variation in day and time, reading were also taken
having variation in location of light shelf - both side
of wall (inside and outside), only exterior side of
wall and only interior side of wall and compared
with same situation of day and time without light
shelf.

Meyerson hall generates various wastes
such as paper, cardboard, plastic, aluminum cans,
glass and other miscellaneous materials. Several
materials such as wood, acrylic, cardboards, metals etc, comes in the fab lab. They produce various
products and create several wastes such as saw
dust, wooden pieces, metal dust etc. Out of all
these, wastes paper and cardboard are the major
one. Papers from printers/plotters are used on one
side and are than thrown to recycle bins or trash
bins. These wastes are than collected and send to
recycle center before their functional value is fully
utilized. Also the saw dust generated from fab lab,
which is initially collected separately, ends up in
trash, possess a value of reuse. For a sustainable
solution, there is a need to make a little intervention in the flow of the waste system. Once the
waste are being collected, materials such as paper,
cardboard, saw dust should be collected and reused in the building itself till they are fully utilized
and then should be disposed for recycling.

S UN PATH A N D SHA D OW STUDY

In designing buildings and structures, architects have constantly focused their attention towards
the sun. It has been both a bane as well as an aid for
building designers: too much sunlight will lead to excessive heating. Hence today architects must not only
design buildings to collect energy from the sun to provide heating and lighting, but also to reject solar energy when it can lead to overheating of the building.
Sun path study helps in understanding the motion of
the sun throughout the year which helps in deciding
the location and orientation of building on site.

Amount and quality of light vary from region
to region. It also varies in the building according to
requirement of space and function. Achieving appropriate light level (Natural + Artificial) helps not only in
achieving low energy consumption of the building, but
it also creates a healthy ambience and increase productivity. Illumination study helps in calculating the
light level at different hours thorough out the year and
hence helps design accordingly to the best or worst
weather condition.

Well ventilated buildings are most needed to
reduce the dependency on mechanical systems and to
reduce the energy consumption for the building. Wind
simulation study helps to calculate the motion of wind
in and around the building. It also helps in understanding the velocity, temperature and inflow angle of the
wind and assists in taking decision for improvising the
conditions.

is an artful school, that has
beautiful views, grounds, and contain “home-felt”
spaces with excellent ventilation. In no case, school
look’s like a place of confinement. Students here
are not only involved in routinely manual work but
also have ample opportunity for pleasures such as
music, lectures, parties, carriage rides, a library,
reading and worship, and excursions.

This school is - an inviolable refuge, a retreat, a protective shelter, a place to escape from
the causes of insanity. The insane cannot be usually healed at home and school is the proper places for the insane. Removal of an individual from
his city or town to the school is for the purpose of
treatment, not for custodial care.

Students are not only the beneficiaries of
the environment and activities provided by the superintendent but also gain from exposure to other
students.

Main aim of the institute is to provide shelter to children roaming on the street and provide with new life. Try to stabilize
their life and help to sustain them through their own skills. Provide them with basic education with understanding their Head Mistress
individual needs. Educate them with affection and kindness. To make them part of society by enriching their behaviours, Quarter

NEEMRANA is located at golden tri-

angle between Delhi and Jaipur. It is 15th century
old fort resort spreading across 2.5 hector on the
hill. It provides unique panoramic view of the landscape till the horizon.

Continuing its legacy of providing a unique
staying experience at fort palace, a new cottage
staying facility is designed at the foot of the place
with different architecture style, language and materiality. The new cottage submerge in the nature
with a surprise in itself. Surrounded by the rich variety of flora and fauna, cottage provides a serene

Exploring different material and technology for construction as against to the stone fort,
the cottage is designed as a mud dome. The dome
is entirely made up of Adobe brick, with necessary concrete bands. Dome sits on square base
with the dimension of 6M X 6M. Dome is 1M high
with diameter of 6M. The final finishing of the
dome and the walls are out of lime plaster and
fresco paintings. Attached with the dome, is the
bathing space, which is inspired by the local stone
construction. A small waste water system is also
developed which will treat water out of the bathroom with natural process and then will be used
for surrounding landscape. The front and rear timber pavilion reflects the language that can be seen
at the fort palace making a continuity.

With a view to provide infrastructural facilities in rural belts, the Bihar government has announced to construct Panchayat Bhavan in 8,463
Panchayats with assistance of World Bank. Panchayat Bhavan shall not only fulfill the functional requirements at panchayat level but also shall become a
landmark representing local self governance. Main
component of Panchayat bhavan are MUKHIYA and
SARPANCH. Other supporting staff for Mukhiya includes Panchayat Sachiv, ward member, Engineers,
Halka kamachari, computer operator etc, whereas
for Sarpanch are Nayay mitra, Jansevak, Health
worker, Supervisor etc. Other Services such as pantry, storage and wash area are required. As it is a
public service building, it is important to include the
factor of physical disability in order to access each
and every function. Idea was to explore a modular
design that could be easily modified for varying site
conditions and bring ease in construction process.

Bihar is rich in building traditions and craft.
Most of the people in the region continue practice
these traditional technologies. At the same time,
there is also a certain degree of change towards
modern materials particularly reinforced cement
concrete. However, quality of such construction is
not up to desirable level due to many complexities involved related to skills and affordability. As
a result, the Panchayat Bhavan will be constructed
with local materials such as Bricks and Bamboo,
which will provide easy availability of materials,
enhance local skills, provide platform to artisan to
move forward with their skills, reduces environmental impact and increase local economy.

SIPs (Structural Insulated Panels) consists

of EPS (Expanded Polystyrene) insulation laminated with structural adhesives to oriented strand
board structural sheathing. It is most air-tight and
well insulated systems available reducing energy
consumption. They are faster construction method as they reduces framing time as much as 50%
as compared to conventional stick frame method.
SIPs are made from renewable wood and the expanded polystyrene insulation contain no HCFs,
CFCs, and HCFCs and the life cycle analysis of SIPs
shows substantial reduction in greenhouse gas
emissions.

ABSTRACT

The housing sector is generating worldwide substantial environmental impacts. In fact, it contributes to
about half of the total energy consumption of high income
countries and is responsible of a major share of greenhouse
gas emissions also in development and transition (D&T) nations. Scientific data on environmental impacts of building
materials and technologies in D&T countries are rather limited and it is difficult to make informed choices aiming at
reducing such impacts. The study aims at filling a gap in the
assessment and documentation of environmental impacts
of building technologies in India and in D&T countries in
general. It is based on a detailed analysis of various walling
technologies used in single family houses of Kutch District,
Gujarat State, India, including traditional, modern and alternative new technologies. Based mainly on primary data,
the impacts have been assessed including the production
chain of materials, their transportation on site, all construction procedures as well as the maintenance activities over
fifty years, whereas the impacts due to demolition of the
structures at the end of their life cycle have been evaluated through qualitative analysis. Environmental impacts
are represented through indicators such as the total energy
consumption (embodied energy), the share of non renewable energies (NRE), the corresponding amount of CO2
emissions and the consumption of water. Various phases
of production processes (construction, transport and maintenance) are represented separately in order to inform on
their respective quantitative relevance.
