environmental impact completely
through skilful, sensitive design. Keeping
in mind that it don’t affect the

BEES (Building for Environmental
and Economic Sustainability)
• A powerful
• Developed by the
Institute of Standards
the tool is based on
and designed to be
practical, flexible, and
• BEES Online, aimed
at designers, builders,
performance data for
LIFE CYCLE ANALYSIS
• Analyse the performance of building products by using the life-cycle
assessment approach specified in the ISO 14040 series of standards.
• All stages in the life of a product are analysed:
• Raw material acquisition
• Waste management
Economic performance is measured using the
ASTM(American Society for Testing and Materials) standard
life-cycle cost method, which covers the costs of initial
investment, replacement, operation, maintenance and repair,
Environmental and economic performance are combined into
an overall performance measure using the ASTM standard for
Multi-Attribute Decision Analysis
For the entire BEES analysis, building products are defined
and classified according to the ASTM standard classification
for building elements known as UNIFORMAT II (a standard
for specifications, cost estimation and cost analysis in USA
LOOP AND HOOK FASTNER
• Swiss engineer George de
Mestral invented the
amazingly useful fastening
material called VELCRO after
seeing how cockleburs from
the burdock plant stuck like
glue to the fur of his dog.
• Based upon that he came up
with the Velcro.
• Also called “hook and loop
fastener” or “touch fastener”
as “Velcro” .
RELAX YOUR WASHING MACHINES,
CLOTHES CAN CLEAN THEMSELVES TOO
• The leaves of Lotus are coated with
nanoscopically tiny bumps and the bumps
are, themselves, covered with a thin layer
• Dirt particles balance precariously on the
waxy bumps but never get a really good
grip on the main surface of the leaves
• The nano-bumps work a bit like a natural
detergent, holding dirt clear of the leaves
so water can easily wash it away.
• So, Now clothing manufacturers
are coating garments like skate
pants with nanofibers so they work
in a similar way.
• The idea is that dirt is held slightly
apart from the main fabric so stains
cannot penetrate deeply; clothes
coated with nanofibers can be
washed clean much more easily.
DIVING COSTUMES MIMICING SHARKS
• Human skin is not
designed for swimming
• Water doesn't flow well
past human skin because
the skin starts to wrinkle.
• For hairy body, every
single one of your hairs
will drag and slow you
down even more.
• To avoid the problem a swimsuit is
manufactured by Speedo company
to mimic a shark's skin.
• FASTSKIN, the tight-fitting suit
covered with tiny v-shaped channels,
just like the ridges (technically
known as placoid scales or dermal
denticles) on a shark's body.
• The idea is that water whizzes along
these channels, reducing drag and
turbulence, so you can swim faster.
• Fits tightly thus, compressing the
swimmer's muscles, helps to reduce
• According to Speedo,
swimsuits like this can boost
a swimmer's speed by up to
HEY!! DRESS UP LIKE A
• If it's going to rain, the spines close up to
protect the seeds inside.
• If it's going to stay dry, the spines open up
to improve the chances of the seeds
•The London College of Fashion are trying to design
biomimetic clothes that could work the same way.
•The fabric could be made with an outer layer of
tiny spikes, only 1/200th of a millimetre wide.
•When it's hot, the spikes would open up to let out
the heat, cooling you down.
•When it's cold, the spikes would flatten back down
to trap air and provide more effective insulation.
BETTER LEARN DRIVING FROM
• 80 million of them in a kilometre square
and yet they never collide.
• Collision avoidance circuitry is under
research, For this the neuron of locust is
• They have a distinctive way of processing
information through electrical and chemical
signals, giving them an extremely fast and
accurate warning system for impending
• Robotics is also in adopting the technique.
FLIGHT OF FREEDOM…..
• A German engineer called Otto
Lilienthal strapped wings to his arms
and jumped off a hill in an attempt
• Though eventually, kill himself
trying to fly like the birds.
• But his pioneering glider
experiments inspired the Wright
brothers to develop their engine-
powered airplanes in the early 20th
saving its life.
